Residual that works as hard as you do.

If you’re in charge of a farming or livestock operation, one of your many jobs is to control weeds on your fence lines and around buildings. You need to keep large areas clear, and you don’t have the time or the budget to keep making retreatments. You need Esplanade® EZ, the pre-mixed, backpack-applied weed control product with the longest-lasting residual on the market. For more information, visit vm.bayer.us.

2019 Bayer Management Manual | Range, Pasture and Animal Health

Recommended Mixing Order for Bayer Range & Pasture Herbicides Read and understand all product labels being used before you begin 1. Start with a clean tank, nozzles and pump systems. Replace any worn or leaking parts.

7. Add suspension concentrates (Esplanade® EZ if treating noncrop areas or fence lines).

2. Calibrate sprayer (see calibration page).

8. Add emulsifiable concentrates (EC’s).

3. Fill tank 1/2 full of clean water.

9. Add water soluble liquids (Method® if treating fence lines or wildlife refuge areas, or Part B of Cimarron Max [2, 4-d + dicamba]).

4. Start tank agitation. 5. If spraying glyphosate, add any water conditioners needed (dry products should be pre-slurried before adding to the tank). Allow to agitate until well dispersed throughout tank. Some water conditioners may lower the pH of the water. A buffering agent may be needed to raise the pH to an acceptable level. 6. Pre-slurry, in water, all dry products (e.g. wettable powders (WP), dry flowable (DF) and drygranule (DG) products. Examples include Cimarron®-Part A of Cimarron Max, Cimarron Plus and/or Pastora®). Make sure to use a clean container.

10. Add glyphosate products, if needed. 11. Add proper adjuvants, if needed or recommended (e.g. non-ionic surfactant (NIS), methylated seed oil (MSO), crop oil concentrate (COC), etc.).

Herbicide Sprayer Calibration Tips Fill the sprayer tank half-full with water. Adjust the spray pump to the same pressure you will use to spray herbicide – broadcast ground sprayer 30 psi (pounds per square inch) or lower pressure to reduce spray drift, down to 20 psi if the spray pattern is maintained. Boomless sprayer calibration Spray a swath on a hard surface that can be easily measured. Measure the width of the swath in feet almost to the edges, allowing for a small amount of overlap. Use this chart to choose your “calibration course.”

If your swath is this wide (feet) 20 25 30 35 40 45 50 Then, spray a row this distance (feet) to equal 1/8 mile 273 218 182 156 136 121 109 A 1/8 acre swath will be sufficient to calibrate your sprayer. Mark the length of the course and drive the course in the gear and at the rpm you’d use to spray. Record your drive time. This is how long it will take to spray 1/8 acre. Park the tractor, maintain rpm used to drive the course and turn on the sprayer. Catch the water being sprayed from the nozzle for the same time it took you to drive the calibration course. A clean, 2-liter soft drink bottle with a hole cut in the side is a handy funnel into a container. If you’re calibrating a cluster nozzle, tie a garbage bag around the nozzle to catch water. Run the sprayer, collecting the output, for the same time it took to drive the calibration course. Measure the volume of the water using a container graduated in pints. Pints of water caught in the bucket are equal to number of gallons the sprayer will deliver per acre. Boom sprayer calibration Measure the nozzle spacing. Use this chart to determine your calibration course length.

Nozzle spacing (inches) 18

Length of calibration course (feet) 227

204

136

102

Mark the course and record the time required to drive in the desired gear and rpm. This is the amount of time required to spray 1/128 of an acre. Catch the water from 1 nozzle for the time it took to drive the calibration course. The number of ounces of water caught will determine the number of gallons that will be sprayed per acre. Catch water from each nozzle to determine if all of the nozzles are delivering the same volume. If the flow is uneven, examine the nozzles and screens checking that everything is the same size and not blocked with debris.

2019 Bayer Management Manual | Range, Pasture and Animal Health

Manage Brush for Clean Fences and Better Wildlife Habitat The exterior fence around your property protects your entire business and is one of the highest capital investments. New fence construction can cost $10,000 to $30,000 per mile. It makes sense to keep the exterior fence clean of woody species. Control brush in and around established fences with Method速 240 SL herbicide with triclopyr (Remedy速 Ultra, Garlon速 3A, Element速 3A and others). This combination provides excellent control of many woody plant species that invade fencelines. Method 240 SL can also be used for sculpting wildlife habitat and can be integrated with other management methods to achieve a preferred habitat for wildlife. Method 240 SL herbicide is labeled for wildlife management areas that are not grazed by livestock. Woody species controlled by Method 240 SL tank mixes include agarito (Mahonia trifoliiota), bumelia (Bumelia spp.), catclaw acacia (Acacia greggii), coyotillo (Karwinskia humboldtiana), flameleaf sumac (Rhus copallina), huisache (Acacia smallii), juniper (Juniperus spp.), lotebush (Zizyphus obtusifolia), honey mesquite (Prosopis glandulosa), pricklypear (Opuntia spp.), tasajillo (Opuntia leptocaulis), Texas mountain laurel (Sophora secundiflora), Texas persimmon (Diospyros texana), whitebrush (Aloysia gratissima), and yucca (Yucca spp.). 2(ee) Recommendation for AZ, NM, OK and TX. Method 240 SL and Esplanade EZ herbicides are labeled for only non-cropland areas and cannot be used on interior fences where domestic livestock graze. Method 240 SL can be used on wildlife management areas that are not grazed by domestic livestock and on exterior fences.

A new Method for managing brush along fencelines AND wildlife habitats.

Introducing another option within our portfolio for ranchers and wildlife land managers. In addition to exterior fence control, Method is now approved for wildlife (non-grazed) area management. Use Method as a foundation within your custom tank mixes to combat broadleaf and brush challenges. Some species that can be managed by Method tank mixes include: Algerita, Bumelia, Catclaw acacia, Coyotillo, Flameleaf sumac, Huisache, Tasajillo, Texas mountain laurel, Texas persimmon, Whitebrush, Honey mesquite and Yucca.

Begin to send soil samples to the labs for analysis. Plan your nutrient program for needed or projected yields. See page 7 for a list of soil testing labs. Fertilize to soil lab recommendations. Lime if necessary. Phosphorus (P) and potassium (K) are nutrients that are virtually immobile in the soil. Plan early applications to get the most benefit from these nutrients. Test for micronutrients as well.

Delay nitrogen (N) applications until soil temperature is 60° F or higher. Now is the time to plan applications and timings for your herbicides. It’s a good idea to order sprayer parts, Velpar® L VU Spot Guns and soil thermometers this month.

Lice are cold weather pests in northern areas of the region. Help protect your cattle with the Bayer product that suits your cattle management style: Clean-Up™ II Pour-On Insecticide with IGR, CyLence® Pour-On Insecticide or Permectrin® CDS Pour-On Insecticide. Check with your Bayer Animal Health representative for more information on these products. Contact your Bayer representative about cattle health products this spring.

21 MARTIN LUTHER KING DAY

January and February are prime months for prescribed burns, which can help with grass stands as well as sandbur/ grassbur (62) control. Coordinate prescribed burning with your local USDA NRCS office, your local burn board, the Extension agent for your county, your state wildlife agency or organizations such as The Nature Conservancy. There are also commercial companies, which can assist you by providing a turnkey burn service. Be aware of local burn bans that are enforced on a county-by-county basis. Inventory and assess early weeds and unwanted grasses in hay meadows and implement a control plan. Contact your Bayer Range & Pasture Specialist for assistance.

Interesting fact: Every ton of bermudagrass hay that is removed from your pastures contains 50 pounds of nitrogen (N), 14 pounds of phosphorous (P) and 42 pounds of potassium (K). Remember the ratio: 4-1-3 for N, P & K removal if you are a hay producer.

31 Fall or winter rains can bring on unwanted weeds or unwanted grass pressures in range and pastures. Cimarron® MAX, Cimarron® Plus or Pastora® can help manage your weed or unwanted grass problems. January is a great time to attend winter CEU or CCA classes to obtain or renew a herbicide applicator’s license. Check with your local Extension offices for dates in your area. Certain products are restricted-use or State Limited Use (SLU) and in most states, both categories require a herbicide applicator’s license. Cimarron® MAX, Cimarron® Plus, Pastora®, Velpar® L VU and Esplanade® EZ are not restricted use products. Cimarron® MAX is SLU in Texas and does require a license to purchase.

Tune up your sprayers–calibrate, change nozzles and update pumps or hoses. Learn about sprayer calibration on page 7. On native range or introduced pastures, late fall or early winter rains can initiate heavy weed or grass germination. Many thistles (53) or broomweeds (38) can germinate in the fall as well as spring. Cimarron® MAX (2, 4-D + dicamba + metsulfuron) or Cimarron® Plus can help manage many problem broadleaf weeds early. Smaller weeds (less than 2 inches) require less herbicide to provide good results.

When yucca (74) begins to break dormancy and approaches bloom, broadcast or use an IPT application of Cimarron® MAX or Cimarron® Plus for control. Check with your local USDA NRCS, Extension agent or your Bayer Range & Pasture Specialist for the proper tank mix. Refer to 2ee recommendations.

Cold weather can stress new calves. Support healthy calves with healthy cows. Bayer Zelnate® DNA Immunostimulant can be administered any time of the year, when administered at the time of, or within 24 hours after, a perceived stressful event.

In southern areas, implement milkweed (46 & 47) control with Cimarron® MAX. In central and South Texas, begin to scout bermudagrass pastures for KR bluestem (60), sandburs/ grassburs (62) or johnsongrass (59).

Based on your location and January soil test results, consider starting nitrogen (N) applications to hay meadows and introduced pastures when soil temperatures reach 60° F or warmer.

18 PRESIDENT’S DAY

Train your herbicide applicator to know how and where Velpar® L VU fits in your brush management program. Consider hiring a professional applicator for this task. Do not apply Velpar® L VU to saturated soil. Always be aware of slope and/or other potential non-target issues with Velpar® L VU. Apply Esplanade® EZ along fencelines, in and around pens, machinery yards and around farm and ranch buildings. Esplanade® EZ can also be used along driveways, sidewalks and other non-crop areas to keep these places clean for up to six months.

In southern areas of the region, flies will soon become a pest. Treat for flies with insecticidal fly tags. Corathon® and CyLence Ultra® Insecticide Cattle Ear Tags are both effective against horn flies and face flies for up to 5 months. Bayer PatriotTM Insecticide Cattle Ear Tags are effective against pyrethroid-resistant horn flies for up to 5 months. Contact your Bayer representative about cattle health products this spring.

14 VALENTINE’S DAY

Begin or continue Velpar® L VU IPT applications to control mesquite, juniper and many other brush species in range and pastures or along fencelines. Velpar® L VU also controls huisache (70), osage orange (bois d’arc), hackberry (69), locust (69), sweetgum and many more unwanted brush species.

If seeding new grasses in range and pastures, an application of Cimarron® Plus (1/8 ounce per acre) can be made pre-planting, pre-emergence or early post-emergence to the grasses. Apply after the new grasses are at the three- to four-leaf stage if applying at early post-emergence. *This is a new and much needed use and label for Cimarron® Plus. Contact your Bayer Range and Pasture representative for the tank mix that will work best for your specific needs. Bermudagrass Producers

Don’t let unwanted winter annual grasses or broadleaf weeds use expensive nitrogen (N), phosphorus (P) and potassium (K). Scout bermudagrass pastures for annual ryegrass (56), little barley (60), cheatgrass (57), rescuegrass (62), downy or Japanese brome as well as broadleaf weeds such as henbit (44), thistles (53), chickweed, Carolina geranium and many others. In central or South Texas, begin or continue to scout for johnsongrass (59) and sandbur/grassbur (62) germination and for KR bluestem (60) emergence. An application of Pastora® or of Cimarron® Plus mixed with glyphyosate can manage both broadleaf weeds and unwanted grasses to ensure a clean hayfield from the beginning. Cimarron® Plus mixed with glyphosate is a good treatment if bermudagrass is completely dormant. Use Pastora® if the bermudagrass has broken dormancy or if any green bermudagrass growth is present at the base of the plant. Pastora® or Cimarron® Plus controls more than 25 grasses and 100–plus broadleaf weeds in bermudagrass pastures.

Early control of unwanted grasses or weeds in rangeland, pastures or in bermudagrass pastures will return the most dollars. Ask your Bayer Range & Pasture Specialist how long control can be expected with a herbicide. Cimarron® MAX, Cimarron® Plus and Pastora® have the residual benefit of Cimarron®. Controlling weeds today is essential, but being able to control weeds that germinate later is a big advantage as well. In native pastures, either Cimarron® MAX or Cimarron® Plus can provide long-lasting weed control that helps to keep your pastures clean. In bermudagrass pastures, Pastora®, Cimarron® MAX or Cimarron® Plus can provide the same benefit. These products can help manage annual milkweed or crotons that emerge later (see pages 41, 46 & 47).

Apply or continue to apply Esplanade® EZ along fencelines, in and around pens, machinery yards and around farm and ranch buildings. Esplanade® EZ can also be used along driveways, sidewalks and other non-crop areas to keep these places clean for up to six months. Begin or continue control of mesquite (71), juniper, huisache (70) and many more species with Velpar® L VU on rangelands and in pastures or along fencelines. Be aware of any possible non-target issues. Review earlier months for application tips on Velpar® L VU. Scout and begin native pasture applications with Cimarron® MAX or Cimarron® Plus if broomweed (38) or other weeds are at economic levels.

Continue to use IPT or broadcast applications of Cimarron® MAX or Cimarron® Plus to control yucca (74). Check with local USDA NRCS, Extension agent or your Bayer Range & Pasture Specialist for the proper tank mix. Refer to 2ee recommendations.

OKLAHOMA YOUTH EXPO, MAR. 13-22, OKC

Implement dewberry (68) control before blooming or berry set with Cimarron® Plus at a minimum of 5/8 ounce product per acre. If seeding any new pastures, an application of Cimarron® Plus, at a rate of 1/8 ounce per acre, can be made pre-plant (before planting), pre-emergence (after planting but before emergence) or early postemergence after the newly seeded grasses have three to four true leaves. Check with your Bayer Range & Pasture Specialist for more information in grass establishment and weed management in newly seeded grasses.

If phosphorus (P) and potassium (K) were applied earlier as suggested, plan your nitrogen (N) applications to maximize hay yields. Soil temperatures need to be 60° F or more to utilize nitrogen (N). If bahiagrass (56) is an issue in bermudagrass pastures, implement control with Cimarron® MAX, Cimarron® Plus or Pastora®. At least ½ ounce per acre of Cimarron® is needed to do a good job on this invasive grass, so do the calculations to make sure the product of choice has that amount of Cimarron® in it. In South Texas, implement KR bluestem (60) control with Pastora®. Two applications will be needed to manage this tough and invasive grass. Repeat the second application four to eight weeks after the first application. Talk to your Bayer Range & Pasture Specialist for additional advice and recommendations. Continue applications of Pastora® for early-season unwanted grass control in bermudagrass pastures. When bermudagrass has broken dormancy, stop any glyphosate applications, in accordance with current labels.

Defend your beef operation at every point. Flies and ticks can wreak havoc on the productivity of your cattle operation. They can transmit disease, destroy property and disrupt feeding – and cattle that aren’t eating aren’t growing. Fly season is starting. Check with your Bayer representative for the best Bayer class of insecticide and delivery method – fly tags, sprays, pourons, insecticidal dust, larvicides – for your management style and area. Contact your Bayer representative about cattle health products this spring.

Begin or continue to scout for many broadleaf weeds. Many weeds germinate when the soil temperature reaches 80° F or more. Once again, soil thermometers and soil probes are very useful tools to have around your farm or ranch. Unwanted vegetation around barns, stalls, working pens and similar areas can become a host for unwanted pests such as flies and/or mosquitoes. Esplanade EZ is a great tool to manage unwanted vegetation in these areas. Both Esplanade EZ and Method 240 SL are tools to help manage weeds, grasses and unwanted brush in fence lines. Contact your Bayer Range & Pasture specialists (4) for specific details and recommendations.

Fall, winter or early spring rains are great indicators of possible heavy weed or grass pressure in range and pastures. Seedling weeds are often hard to detect. Scouting and weed identification are your best tools. Start early! Download weed identification information (8) to help you address your farm or ranch weed issues. Early application of Cimarron® MAX or Cimarron® Plus is useful in maximizing grass production and can help stop late-season weed problems. These products in a good program can help manage many weed or grass problems. Talk to your Bayer Range & Pasture Specialist to determine which one fits your program: Cimarron® MAX-native, bermudagrass or introduced grasses; Cimarron® Plusnative, bermudagrass or introduced grasses (also new seeding plantings); Pastora®-bermudagrass. Implement bahiagrass (56) control in bermudagrass pastures or hay fields with any of the above products. Ensure you have at least 1/2 oz/acre Cimarron® Plus or MAX (metsulfuron) in your mix.

In bermudagrass pastures, initiate control or suppression of sandbur/grassbur (62), johnsongrass (59) and KR bluestem (60) with Pastora®. Applications to sandbur should be made when the seedlings are two inches or less. Johnsongrass (59) should be in the 12- to 18-inch size, and in the preboot stage. Good coverage on both of these species is also very important. Nozzle spacing and size of nozzles are also very important. Flat fan type nozzles with narrow spacing (20 inches) are recommended. Pastora® can be applied in nitrogen (N) fertilizer, but should be limited to 30 pounds of actual nitrogen (N) per/acre or less. Talk to your Bayer Range & Pasture Specialist to ensure best results. Scout and continue or begin applications of Cimarron® MAX or Cimarron® Plus herbicide in native or introduced pastures. Early applications of these herbicides when weeds are small (less than two inches) will provide the best results and most return for dollars invested..

1 Herbicide timing and weed or grass identification are keys to success. Control weeds or grasses when they are small and actively growing to obtain maximum benefits from herbicide dollars. Check page 8 for some excellent resources for identifying problem weeds or contact your local Bayer Range & Pasture Specialist for further help. Flies can have a serious impact on your livestock from now until October. Do you notice your cattle bunching up? They may be trying to get away from flies. The cattle on the outer edge of the bunch are being bitten, but the cattle in the middle may be suffering heat stress. No matter where the cattle are in the bunch they are not grazing and not gaining weight. Ask your veterinarian whether sprays, pour-ons, insecticidal tags, dust bags or an oral larvicide would be best for your operation.

5 CINCO DE MAYO

Continue to scout for sandbur/grassbur (62) and johnsongrass (59), along with KR bluestem (60) and bahiagrass (56) in bermudagrass pastures. Remember these tips to get the most from your Pastora® applications: Apply when bermudagrass has less than two inches of growth; Apply when sandbur/grassbur seedlings are two inches or smaller–if the seedlings are larger, a tank mix of Pastora® mixed with glyphosate may be recommended or needed. Check the Pastora® label for additional information; Apply when johnsongrass is in the pre-boot stage; Limit nitrogen (N) to 30 pounds actual nitrogen (N) when applying Pastora®. Coverage is essential, so flat fan type nozzles on 20-inch spacing are preferred.

BRD is often overlooked in summer, especially on cow-calf operations because they don’t expect to have to treat calves for stress-related diseases like pneumonia this time of year. But in drier situations, with young calves going to water while following the mother, those calves are right at the level where the animals are kicking up dust and they can’t get fresh air. Calves breathe in particulate that can interfere with the respiratory tract’s normal defense mechanisms. Contact your Bayer representative about cattle health products to plan your fall herd health program.

Consider planting wildlife-friendly food plots. If you used Cimarron® MAX or Cimarron® Plus, you can successfully plant crops that will benefit wildlife species or provide additional grazing forages for your cattle. Evaluate your pastures after they’ve been grazed off to see which grasses are increasing or decreasing. Clean out stock tanks and remove algae growth. Maintain the integrity of your dams by removing vegetation that could weaken the structure through root growth.

Continue your IPT plan with Velpar® L VU to control mixed brush species such as mesquite (71) and juniper with Velpar® L VU, in range and pastures as well as along fencelines. Always be aware of non-target species or off-target movement. Continue to monitor nutrients in bermudagrass pastures. Apply additional nutrients if needed. One ton of bermudagrass hay contains 50 pounds of actual nitrogen (N), 14 pounds of actual phosphorus (P), and 42 pounds of actual potassium (K).

October is a good month to begin early season soil testing. Send soil samples to the lab for fertility analysis. Send hay samples to the lab for complete nutrient analysis. Knowing what your hay provides will help determine your livestock feeding needs for the upcoming winter months.

Check the long-range weather forecast for your area. Allow three weeks before the first frost for huisache (70) and Sericea lespedeza (50) applications.

Fall and winter are prime time for parasite infections. Cattle are exposed to internal parasites all summer while grazing. Cattle then carry the infections with them when they come off pasture, which can negatively affect how well they feed. Deworming in the fall as soon as cattle are coming off pasture helps keep the herd clean during winter and maximizes the benefits of winter hay and supplements. Cydectin®(moxidectin) Pour-On or Cydectin® (moxidectin) Injectable can be an important part of your fall and winter parasite protocols. Cydectin uses a unique molecular structure leading to greater distribution in the fat of the animal. Because of this, both Cydectin Pour-On and Cydectin Injectable kill key internal and external parasites such as lice, mites and grubs. *Keep Cydectin out of reach of children.

Winter is a prime time for parasite infections. Biting and sucking lice are external parasites that cause an estimated $126 million of annual economic loss in the U.S4. Lice reproduce more in the cold weather. Cattle also tend to bunch together to stay warm, which quickens the spread of lice throughout the herd. Clean-Up™ II Pour-On Insecticide with IGR kills both adult lice and eggs.

Four Points to Include in Ranch Pest Control Defense Point 1 – On the animal, treat for flies, lice, ticks and other external parasites and pests with properly applied pour-on or spray insecticides, insecticidal ear tags, dust bags or backrubbers with insecticides. Defense Point 2 – Keep the barn, stalls, corrals, working pens and ranch structures free of vegetation that provides resting cover for flying pests. Use a premise spray to control crawling insects. Defense Point 3 – In the environment, use fly traps, fly baits and spot sprays to control pests. Screens can help keep pests out of indoor working areas. Clean manure out of working areas as part of the annual herd health management program for your livestock. Defense Point 4 – In the animal, use feed-through larvicide products to control flies that nest in manure.

One hand, 100 flies To help producers calculate the number of flies, Bayer Animal Health estimates that 100 flies can fit in the area covered by an average-size hand — fingers, thumb, and palm included.

2019 Bayer Management Manual | Range, Pasture and Animal Health

Fly Geography The location of the fly on the cattle can help you determine which pest you are working to control. House fly The house fly is a filth fly, feeding on manure, old feed, waste, sweat, and tears. They transmit disease just by landing on the cattle and have been known to carry up to 65 diseases. Stable fly Commonly found on the lower legs of the cattle, stable flies feed on blood. Their bite is painful, and they usually take two to three bites to get a satisfactory blood meal. Stable flies generally cause cattle to bunch to avoid their bites. Horn fly The horn fly bite is not as painful as that of a stable fly, but it does feed on the blood of cattle. Horn flies typically bite 30 times per day and are found on the back and sides of the animal. Cattle swish their tails to shoo the horn fly away. Face fly The face fly feeds on nasal secretions and tears of cattle. They are known to transmit pinkeye in cattle and present the risk of transmitting bacteria and other viruses.

2019 Bayer Management Manual | Range, Pasture and Animal Health

Horn Fly Control Horn fly control is important for animal welfare, performance and herd health. If horn flies are not controlled, research has shown that animal gains are often reduced by 0.09 lbs/day for nursing calves and 0.20 lbs/day for stocker cattle. To help reduce problems with resistance, chemical classes of topical insecticides should be rotated each year. The topical products currently available can be classified as pyrethroids, organophosphates or avermectins. Remember to rotate chemical classes and not just brand names or application methods.

How Fly Tags Work Insecticidal fly tags work by “rubbing insecticide off as the cow interacts with her calf, herself through grooming, and her peers in the pasture,” says Larry Hawkins, senior technical service veterinarian with Bayer Animal Health. Fly tags are made by mixing the insecticide with a soft plastic to allow the insecticide to easily pass from the fly tag to the cattle. Most fly tag products are effective for up to five months (150 days) and protect cattle from flies and ticks. Temperatures, rainfall, and how frequently the cattle wade into the pond can impact the fly tags’ effectiveness, Hawkins says. Use two tags per animal to get better control. A tag in each ear of your livestock will help spread the insecticide around the herd. Hawkins also suggests attaching the tags so that a portion hangs below the perimeter of the ear.

Options to Control Cattle Lice Excerpted from Veterinary Entomology, Cornell University*

Female lice lay their eggs by attaching them to hairs with a strong glue to prevent them from falling off. The eggs, known as nits, hatch in 10 to 14 days, and the young lice (nymphs) complete their development within several weeks. Infested animals become irritable and difficult to work with, especially during milking. People working around lousy animals are exposed to greater risk of injury and are also annoyed by stray lice they pick up from infested animals during handling. Before selecting an insecticide, consider how it can be applied to meet individual needs and production practices. There are several categories of application methods: self-application devices, whole-animal sprays, pour-ons, and dusts. Insecticides must be used properly to achieve satisfactory control of lice. Many louse-control products require 2 treatments, 10 to 14 days apart. The second treatment is essential to kill newly hatched lice that were present as eggs at the time of the first treatment and were therefore not killed. Failure to make the second treatment in a timely manner will create problems requiring many more subsequent treatments.

Three Reasons to Use Insecticide Right 1. Save money Always read and follow the product label to find the right dose of insecticide for your livestock or run the risk of pouring on extra dollars by over application or spending double the dollars by under applying. Larry Hawkins, senior technical service veterinarian with Bayer Animal Health, says, “Research-based data determines what dose to use. We want to use insecticides to get the best performance possible and use the least amount of product.” 2. Right dose + right place = best results Most insecticide doses are based on the weight of the livestock. Applying a set amount across the whole herd could be a waste on smaller animals and not enough of a dose for larger animals. A set of scales will help you determine the right dose. Misapplication can be a problem, too. For example, Hawkins says a certain species of lice is found primarily on the head of cattle. If the insecticide is applied to the body and not the head, this is an underdose. 3. Reduce the possibility of resistant parasites Some parasites or bugs may survive an under-dose. “If we kill off the ones that are susceptible, then the only population that is left are the ones that are resistant to that particular insecticide,” Hawkins says.

THE LINE PARASITES CROSS AT THEIR OWN RISK

Better health means better production. So why not choose better parasite control? Cydectin® (moxidectin) Pour-On dewormer kills key parasites that threaten your beef cattle and has little to no impact on beneficial dung beetles. Make a healthier choice for your herd. Choose Cydectin.

Tips to Avoid Resistant Insects Insecticide resistance is the repeated, absolute failure of an insecticide to produce the intended effect on an insect population as a result of selection pressure. Reduced susceptibility is not absolute failure of a product, but reduced sensitivity to it relative to previous sensitivity. If an insecticide’s mode of action (MOA) no longer affects the target pest in the expected way at all – regardless of dosage or duration of exposure – then the pest is resistant to it. Effective insect resistance management and rotation practices • Rotate insecticides with different MOAs, not just different brands or active ingredients. • Rotate late in the season to cut down on resistant overwintering flies. •

Discontinue using insecticide ear tags as soon as horn fly numbers decline in the fall, to minimize the flies’ exposure time to the insecticide and help ensure fly populations that proliferate later in the season remain susceptible.

• Rotate MOA classes between applications when applying insecticides more than once per season or year. • Use insecticides at their full doses according to product label recommendations.

Needle Selection Basics Proper needle selection is important for reducing the risk of broken needles, and it makes the process of giving injections easier. Both needle length and gauge should be considered. Shorter needles (i.e. 5/8 and 3/4) make it easier to properly give subcutaneous injections. For intramuscular injections, a 1-inch long needle is sufficient even on bulls and cows; using a longer needle increases the risk of the needle bending and breaking. For thicker products, a 16-gauge needle works well. Either a 16 or 18-gauge needle is fine for thinner products. Avoid needles that are less than 18-gauge when giving injections to cattle.

Follow Label Instructions for Injected Medicines When it comes to using injected medications in your cattle herd health program, follow the product label recommendations for injection sites. Using more than the recommended amount can reduce how well the product works and can increase withdrawal times. If the label doesnâ&#x20AC;&#x2122;t specify an amount, then a good guideline is to use a maximum of 10 mL per injection site. For example, if the dose was 60 mL, then that amount should be divided into 6 locations, spaced at least 3 to 4 inches apart.

Understand Flight Zone to Make Cattle Movement Easier The flight zone is the comfortable distance livestock maintain between you and them. The flight zone of cattle will vary depending on their disposition. Calm cattle have a very small flight zone while more temperamental cattle have a larger flight zone. The flight zone will increase as cattle become excited or agitated. Cattle should be worked from the edge of the flight zone, or the pressure zone. When you move into the pressure zone cattle will move away from you and as you move out of the pressure zone cattle will generally stop.
