Weeding Out The Weeds Considerations for Weed Control This Summer Dallisgrass
by Matt Elmore, Ph.D.
I
t seems we never get a break from the weeds in Texas. The mild winter weather was great for many winter annual weeds, which have been owering in recent weeks. Meanwhile, summer annuals such as crabgrass have germinated but are still lurking below the turfgrass canopy. Summer perennial weeds such as dallisgrass (Paspalum dilatatum) and Virginia buttonweed (Diodia virginiana) are also growing well, even if you applied a pre-emergent to control annual weeds. With
all of these weeds, how will you develop a strategy to control them this summer?
1SPQFS 5VSG .BOBHFNFOU Proper turfgrass management is the key to successfully managing weed infestations. This is probably something you hear all the time, but that is because it’s true. Weeds are not the cause of poor turfgrass, they are the result of poor turfgrass. Proper management can reduce our reliance on herbicides for weed control.
Increase mowing height Increasing your mowing height to the higher end of the range recommended for a particular turfgrass species may help reduce infestations of annual weeds such as crabgrass. Research has consistently demonstrated ~50% reductions in crabgrass by raising the mowing height from 1� to 2� and further reductions are usually observed by mowing at 3�.
Fertilize with nitrogen. Proper nitrogen fertilization increases the competitive advantage of grasses against broadleaf weeds. Research

shows that moderately fertilized turfgrass has fewer broadleaf weeds than under-fertilized turfgrass. A great example of the value of nitrogen in reducing broadleaf weeds is the Park Grass experiment that began in 1856 at the Rothamstead Experiment Station near London. In this experiment, a single yearly addition of nitrogen at about 1 pound of nitrogen per 1000 square feet changed the species composition from about 40 plant species to just a few grass species1. While the Park Grass experiment simulates a hay ďŹ eld, short-term turfgrass experiments have yielded similar results. Keep in mind that it is important to fertilize turfgrasses only when they are actively growing and have fully greened up. Nitrogen fertilizer should not be used when turfgrass is just emerging from dormancy in spring, or when growth slows in fall. Fertilization at the wrong time can increase fungal disease problems and promote weeds such as annual bluegrass (Poa annua) because they are growing more rapidly than
warm-season grasses in the early spring and fall.
Aerate. Core cultivation (aeriďŹ cation) is another important cultural practice, especially in areas that receive a lot of foot or equipment trafďŹ c. Goosegrass (Eleusine indica) and prostrate knotweed (Polygonum aviculare) are summer annuals that outcompete turfgrass in compacted soils. These weeds often grow along the edges of sidewalks and highly trafďŹ cked areas on athletic ďŹ elds. Core or solid tine cultivation is a beneďŹ cial practice even in lightly trafďŹ cked lawns, but especially in the compacted areas where goosegrass and prostrate knotweed thrive. It is best to aerate when the turfgrass is actively growing. The upcoming months of May and June are great months to aerate.
)FSCJDJEFT Even with proper management, weeds tend to invade many lawns. Herbicides are good tools to help us manage weeds. Here are some new and old solutions for managing a few of our most problematic weeds.
Crabgrass Pre-

emergent herbicides are the most economical method to control crabgrass. Although crabgrass has already germinated this year and the window to apply these products has passed, there are some options that provide both preand post-emergence control. Most products that contain dithiopyr (Dimension) are labeled for control
of crabgrass prior to the tillering stage. New this year, Dimension 2EW (this formulation only) will be labeled to control large (Digitaria sanguinalis), smooth (D. ischaemum), and southern (D. ciliaris) crabgrass up to the ďŹ ve-tiller stage. Note that it may not control india (D. longiora) and blanket (D. serotina) crabgrass post-emergence. See the supplemental Dimension 2EW label for more information on rates and adjuvants. Other options for post-emergence crabgrass control include products that contain quinclorac (Drive XLR8 or Quinclorac 75 DF). Including methylated seed oil-based adjuvants will increase quinclorac efďŹ cacy compared to other adjuvants. Quinclorac has limited soil residual, so combine it with a pre-emergence herbicide for severe infestations. Quinclorac should not be applied to St. Augustinegrass or centipedegrass.
Dallisgrass This perennial grass cannot be controlled with preemergent herbicides (Figure 1). In a post-MSMA world, herbicide options are limited. Herbicides are most effective against dallisgrass when applied in the fall and early spring. Sequential application of Tribute Total beginning in the fall can provide dallisgrass control in bermudagrass and zoysiagrass. Spot treatments of Celsius will suppress dallisgrass in St. Augustinegrass and centipedegrass. Ornamec will also control dallisgrass but can only be used in zoysiagrass. These herbicides are most effective when applied in the fall and early spring. See the factsheet at aggieturf. tamu.edu for more information on proper application timing. Depending on the size of the infestation, a shovel may be your

best option for dallisgrass control. Make sure to remove the entire clump that contains the underground rhizomes. Some topsoil may be necessary to ďŹ ll in the hole.
Asters This summer annual weed is abundant in North and Central Texas. Slender aster (Symphyotrichum ligulatum) is a common aster found in turfgrass. It may be especially problematic this year since it germinated especially early, before most pre-emergent herbicides were applied. I saw slender aster seedlings in the DFW area in December that were not killed by subsequent frosts. This weed is very easily controlled by most post-emergence herbicides that control broadleaf weeds. However, it is important to control it in the
vegetative stage during the spring and early summer (Figure 2). I get lots of questions about this weed when it owers each September, but by this time it is too late for control. Even if a herbicide kills the owering plant, the woody stem it produces will remain all winter. It is important to control this weed before it transitions from the vegetative to reproductive phase.

Pest Management Gone Wrong: When Nothing Seems to Work! by Erfan Vafaie
I
t’s a bright beautiful sunny day and all of your crops are ourishing. With great conďŹ dence in how to grow your crops and good strategies to manage your pests, you have things completely under control.

Until now. You have a particular pest, one that you had no problem managing before, that is not submitting to your will! You may be using the exact same strategy as before or perhaps you have upgraded your sprayer, but you have no idea why you are not getting the kind of control you should be. At this point, you are greatly inclined to blame Obama, but before doing so, there are several factors to consider when not getting the pest knockdown you have been used to.
*EFOUJmDBUJPO To an untrained eye, an aphid is an aphid, and a whitey is a whitey. Anyone with extensive experience dealing with pest insects will know that this is not quite the case. There are around 250 agricultural pest species of aphids and over 1550 species of whitey described. Depending on how the insecticide is designed to kill the pest in question, it can effectively kill some and not other closely related pest species. For example, Acephate 97UP has whiteies on the label, but has “sweetpotato & silverleaf whiteyâ€? as exceptions. So if you happen to have a different whitey species as before, you may be spraying an insect that is not susceptible to your insecticide. Different species can also vary in their behavior, which also impacts the effectiveness of an insecticide. For example, the western ower thrips, as the name would suggest, tend to spend time in the owers, whereas onion thrips and chilli thrips can be found on leaves and stems. Contact insecticides are often less likely to penetrate into the ower heads, making contact insecticides less suitable for western ower thrips. By assuming that you always have the same species of thrips on your crop, you may be using a management strategies that is not best targeted to the behavior of your pest species.
Figure 1. There can be several factors contributing to the ineectiveness in managing an insect pest. This diagram illustrates some of the factors discuss in the article. .":t+ 6 / & 5 & 9" 4 / 6 3 4 & 3: - " / % 4 $ " 1 & " 4 4 0 $ * "5 * 0 / 8 8 8 5 / - "0 / - * / & 0 3 (

$VMUVSBM 1SBDUJDFT Keep it clean: We understand the importance of keeping a kitchen clean, to prevent mold growth and prevent an uninvited trail of ants in your home. The same logic applies in the ďŹ eld and in greenhouse. Keeping a clean and sanitary environment helps reduce pest pressure by removing potential habitat, food, and sources of pest eggs. Fallen leaves, fallen fruit, pet plants, and weeds can all act as reservoirs for pest populations: remove them. Some weeds can be considered beneďŹ cial for attracting predators or other pollinators, whereas others can become a source of insect pests. Monitoring nearby weeds to identify which plants may be attracting pests to your area and be sure to remove them. If you plan on keeping those weeds around for beneďŹ cial insects, be sure to monitor the plants for pest populations throughout the season as well, otherwise you may be encouraging the problem you are facing. Fertilization rates: Over-fertilization can encourage pest populations. Twospotted spider mites, for example, thrive in nurseries and greenhouses where plants are over-fertilized. The excess nitrogen in the plants is the perfect material for the spider mites to make more babies. If you ďŹ nd yourself unable to keep the two-spotted spider mites in check, consider temporarily (or permanently) decreasing fertilizer rates until you get the mite populations in check. Temperature control: Insect metabolism increases and generation time decreases with increasing temperature, so high temperatures are rather favorable for insect population growth. As such, a heated greenhouse in the winter or springtime may be a contributing factor to the seeming
Figure 2. Using water sensitive cards can be an eective means of knowing your spray coverage. When using a contact insecticide, make sure you have good spray coverage (~550 droplets per square inch). Don’t decrease the dosage of insecticide because you have excellent coverage – read the insecticide label and follow directions to ensure that a lethal dose is delivered to the pest. ever-increasing population of an insect pest. Consider decreasing the temperature temporarily while you try and get the pest population in check. Least Infested to Most Infested: If you have a pest population that has overrun a part of the farm, employees and other personnel should be limiting movement between that site and other sites on the farm. If personnel still need to get into the area for watering and maintenance, consider having people work in the infested area at the end of the day, otherwise, they may be assisting the insects spread all over the farm. Small insects, such as thrips, aphids, and whiteies, can easily latch onto clothes and be transported around by humans.
$IFNJDBM $POUSPM The most commonly used tool by the southern nursery and landscape
growers to combat pests involves the use of chemical insecticides. If used correctly, insecticides are effective, relatively rapid, and give a consistent result. However, when used incorrectly, such as lack of chemical rotation and awareness of insecticide resistant populations, insecticides can become a broken crutch. Chemical Rotation & Insecticide Resistance: Rotating chemical insecticides is vital for targeting different life stages of an insect pest and for insecticide resistance management. Different insecticides can target different insect life stages, such as eggs, nymphs, or adults. By rotating insecticides that target different life stages, you have a better chance of removing all sources of the population. Additionally, you want to ensure that you are rotating

modes of action: the mechanism in which the active ingredient of the insecticide (often the top on the “Ingredientsâ€? list) acts on the insect to kill it. Although it can be tempting to use the same highly effective insecticide over and over again, such a practice can result in insecticide resistance. According to pesticideresistance.org, sponsored by Michigan State University, there are over 165 cases of reported insecticide resistance in western ower thrips and 578 cases of sweetpotato whitey insecticide resistance. Resources, such as iraconline.org (click “Modes of Actionâ€?) can help you determine whether the insecticides you are using belong to different mode of action groups, so that you can prevent the development of insecticide resistance in your pest populations. If you think you are already on the verge of battling an insect that is resistant to the insecticides you are using, considering using chemicals with more “mechanicalâ€? approaches to management, such as horticultural oils or insecticidal soaps. These products act by either suffocating or causing damage to cell membranes, making it less likely for insects to develop resistance against them.

Coverage: Perhaps you just got a new sprayer, and even though it’s suppose to be better than the last one, you are having more challenges with managing your pest (Figure 2). The problem may be related to coverage and dosage delivery. If you are spraying a contact insecticide, make sure you have your sprayer calibrated just right for the insecticide being used. Additionally, don’t decrease the insecticide rate just because you are getting exceptional coverage; the insecticide is most effective at the dosage

recommended on the label. Deciding to use less insecticide because the delivery mechanism is highly efďŹ cient may result in sub-lethal levels of insecticide delivery to the target. Boosting the Pest: Believe it or not, some insecticides can actually encourage some pest populations. For example, a study in 2011 found that applications of imidacloprid caused outbreaks of spider mites on elm trees in urban landscapes (Szczepaniec et al. 2011 published in PLoS One). According to UC IPM (ipm.ucdavis. edu), acephate, organophosphates (i.e. malathion), carbamates (carbaryl), and pyrethroids (i.e. bifenthrin, cyuthrin, uvalinate, and
permethrin) can also cause spider mite outbreaks. If you are spraying several chemicals and are ďŹ nding that your pest is still thriving, you may need to investigate whether any of the chemicals in your rotation are causing the pest outbreak. Consider using horticultural oils or insecticidal soaps and gradually adding the different chemicals back into your rotation to ďŹ nd out what may be causing the boost to your pest population.
$PODMVTJPO Pest management can be challenging as it is, but add elements such as insecticide resistance, fertilization rate, sanitation, and differences between insect species, and pest management can sometimes seem near-impossible.

Please Report Crepe Myrtle Bark Scale by Mengmeng Gu, Ph.D.
C
Mengmeng Gu , Ph.D. is an Assistant Professor/Extension Specialist at TAMU. She received her BS in landscape horticulture and MS in ornamental horticulture from Beijing Forestry University
repe myrtle bark scale (CMBS), Eriococcus lagerstroemiae or Acanthococcus lagerstroemiae (Kuwana) (Eriococcidae: Acanthococcus), is an emerging new pest threatening the production and landscape use of crepe myrtles, a $66 M wholesale value crop in 2014, which increased 42% from 2009. The number of crepe myrtles sold in 2014 was close to 5 M, 64% increase from 2009. It was recognized among the top nine pests reported in the past two years by the Greenhouse Grower magazine and was listed as one of “key management arthropods�. In the most recent Pest Management Strategic Plan for Container and Field-Produced Nursery Crops in FL, GA, KY, NC, SC, TN, and VA: Revision 2015 [(PMSP) coordinated by Southern Nursery Integrated Pest Management Working Group and funded by the Southern Region IPM Center] it was noted that “no biological control of the crape myrtle bark scale is known�. There is no report of CMBS in California currently, but California Department of Food and Agriculture has rated
A crepe myrtle with heavy scale infestation, which causes the black sooty mold on branches and leaves. CMBS as “14â€? on a scale of 1-15 with 15 being the highest point in its pest rating proposal (http://blogs.cdfa.ca.gov/ Section3162/?tag=crepe myrtle-scale), because it: ¡ is “likely to establish a widespread distribution in Californiaâ€?; ¡ has “moderate host rangeâ€?, (continued on page 24)
The total wholesale value of crepe myrtle and the number of plants sold in 1998, 2009 and 2014, based on data from three Census of Agriculture. Real value was calculated based on consumer purchase index in 1982. .":t+ 6 / & 5 & 9" 4 / 6 3 4 & 3: - " / % 4 $ " 1 & " 4 4 0 $ * "5 * 0 / 8 8 8 5 / - "0 / - * / & 0 3 (

¡ has “both high reproduction and dispersal potentialâ€?; and ¡ could cause both economic impacts [“lower crop yield, lower crop value (includes increasing crop production costs), and trigger the loss of markets (includes quarantines)â€?], and environmental impacts (“trigger additional ofďŹ cial or private treatment programs; and signiďŹ cantly impacts cultural practices, home/urban gardening or ornamental plantingsâ€?). Unsightly, sooty mold caused by CMBS infestation threatens to diminish the popularity of crepe myrtle with growers, landscapers and consumers. People have started to avoid planting crepe myrtle. Scale insects can be very hard to control and timing of treatments
CMBS has been reported on the following 17 genera in 13 families with important genera and species in the U.S. indicated by bold fonts. 1. Buxaceae: Buxus 2. Cannabaceae: Celtis sinensis 3. Combretaceae: Anogeissus, Anogeissus latifolia 4. Ebenaceae: Diospyros kaki 5. Euphorbiaceae: Mallotus japonicus 6. Fabaceae: Dalbergia eremicola, Glycine max 7. Lythraceae: Lagerstroemia indica, Lagerstroemia speciosa and Punica granatum 8. Moraceae: Ficus carica 9. Myrtaceae: Myrtus 10. Oleaceae: Ligustrum obtusifolium 11. Pentaphylacaceae: Ternstroemia japonica 12. Phyllanthaceae: Glochidion puberum 13. Rosaceae: Malus pumila, Rubus

Scale found on a native American beautyberry (Callicarpa americana) next to an infested crepe myrtle in Texarkana, TX has been conďŹ rmed as CMBS by both morphological and molecular tools. can be critical. Landscapers, groundskeepers, homeowners, and even buyers have begun to notice CMBS, often after signiďŹ cant buildup of black, sooty mold on trunks, branches and twigs. In many cases sooty mold may be mistakenly attributed to the crepe myrtle aphid, a common and relatively easy to control pest on crepe myrtles. Some may think this is only a serious issue for crepe myrtle producers (well, there are 34 states of them!) and those use crepe myrtles in landscapes. WRONG! In its native range CMBS has been reported on plants from thirteen families, including economically important crops such as soybean (Glycine max), apple (Malus pumila), brambles (Rubus sp.), boxwood (Buxus sp.), cleyera (Ternstroemia japonica), ďŹ g (Ficus carica), persimmon (Diospyros kaki), and pomegranate (Punica granatum), in addition to crepe myrtles. The American native plants in three genera, Celtis, Diospyros
and Myrtus, could very likely be potential hosts of CMBS. In addition, both morphological and molecular identiďŹ cation have conďŹ rmed that scales found on native American beautyberry plants (Callicarpa americana, Verbenaceae) next to CMBS-infested crepe myrtles in Texarkana, TX were indeed CMBS. This would add the 14th, to the existing 13 families, reported with CMBS infestation. There are so many examples of exotic pests (benign, not too harmful or even useful at ďŹ rst glance) becoming invasive and causing signiďŹ cant economic and environmental impacts, that CMBS should be taken very seriously. Here’s how you can help if you see something similar to Fig. 3 on crepe myrtle and ‘pink blood’ comes out when smashed, report it at www. eddmaps.org! An educational session is scheduled at the Nursery/Landscape EXPO in August to provide more information on this issue.

Notes fr om SFA Gar dens
SFA Gardens Industry Day 2016 by Dr. Dawn Stover
S Dawn Stover is a Research Associate with the SFA Mast Arboretum in Nacogdoches, Texas. As a Research Associate, Dawn currently manages the living plant collection within the SFA Mast Arboretum and the horticulture greenhouse facilities.
FA Gardens hosted our ďŹ rst ever Industry Day last June, and we had a grand time touring the gardens and listening to expert speakers who introduced us to some remarkable plants with great potential. Since it was our ďŹ rst go-round, we deďŹ nitely had a few wrinkles to iron out. All in all, it was a pretty great day and we’re ready for a bigger and better event this year. We are ready to host another Industry Day this summer with a few changes to make it an even better learning and networking opportunity for all of our horticulture industry folks. The event itself is designed to be tree and shrub based complement to the annual color programs at the Dallas Arboretum Plant Trials Field Day and the East Texas Horticultural Field Day at Overton, and will again follow on the heels of both events this coming June. Last year, SFA Gardens director, Dr. David Creech, led a large tour group through each of our gardens and collections, a lot to take in at one time, and folks had a hard time hearing many of the jewels of plant knowledge and history that Dr. Creech doled out. This year, we welcome folks to tour any and all of our gardens at their leisure in the cooler morning hours. Yes it’s June in Texas, so cooler might be a relative term. Dr. Creech will offer two guided tours at 8:30 a.m. and 10:30 a.m., focusing on the outstanding collection in the Ruby Mize Azalea Garden. Folks will have an opportunity to lunch on their own in our quaint little town, with a designated restaurant for those who want to gather together. At 1:30 p.m., we will gather in the Ina Brundrett Conservation Education Building at the SFA Pineywoods Native Plant Center.
This year’s speaker line-up is impressive. Robert “Buddy� Lee, the inventor of EncoreŽ Azalea and the current Director of Plant Innovations for Plant Development Services will be speaking about “New Woodies on the Horizon.� Dr. James Robbins, Extension Specialist in commercial ornamental plants at the University of Arkansas, will highlight “Disposable Woody Plants.� Dr. Mike Arnold, Professor of Horticultural Sciences at Texas A&M University, will present “Droughts and Deluges: How To Survive With Native and Adapted Woody Plants�, and Dr. Todd Lasseigne, President and CEO of the Tulsa Botanic Garden will offer outstanding selections from North Carolina to Oklahoma and parts in between. Folks that attend the lectures will be eligible for CEU’s - details will be published on our website. What can you expect if you have never been to SFA Gardens? It’s an astonishing world of plant collections, including Texas’ largest azalea garden. Our collections include everything from edibles, to natives and ornamentals. SFA Gardens is the sum of several parts: the Mast Arboretum, Ruby M. Mize Azalea Garden, Pineywoods Native Plant Center, Gayla Mize Garden and our newest addition of the Jimmy Hinds Park. And while we leave the annual color to the Dallas Arboretum and Overton Experiment Station, with over 15,000 different plant taxa, there is something here for just about everyone. Make plans to attend Industry Day at SFA on June 24, 2016. Visit our website at www.sfagardens.sfasu.edu for more information, or contact me directly at dawnstover@sfasu.edu or 936-468-4404. Keep growing!
