Canola flea beetles emerging

By Janet J. Knodel Extension Entomologist

Spring temperatures have warmed up above 60 degree F causing the flea beetles to emerge from overwintering areas and search for volunteer canola and other Brassicaceae weeds (wild mustard) to feed on. Crucifer and striped flea beetles have been observed in the northeast (Anitha Chirumamilla, LREC), Benson County (Scott Knoke) and northwest Minnesota (Dave Grafstrom). Both the striped flea beetle and the crucifer flea beetle have been observed with the crucifer flea beetle being more common. Flea beetles are easy to identify in the field by their flea-like hopping behavior. The crucifer flea beetle adult is a small, oval-shaped, dark beetle with an iridescent blue sheen on the black wing covers, measuring about ? inch long. The striped flea beetle adult is similar to the crucifer flea beetle in size and has two yellow stripes on its black wing covers.

As canola is planted, farmers and crop consultants need to plan to scout for flea beetles as soon as the crop emerges, at least 2-3 times a week. Insecticide seed treatments need to be confirmed they are working and providing good protection against flea beetle damage during the first 3 weeks after canola emergence. Feeding damage is often worst with hot temperatures, low moisture and low plant stands. Continue to scout until canola is in the 6-8 leaf stage when the crop can tolerate most flea beetle feeding pressure.

• Increased early season vigor

• Phosphorus and Zinc to drive rooting & cold start the crop.

• Zinc to help with early season hormone production, ie. Auxin for root and shoot growth.

• Convey Technology to help with early season stresses, such as cool soils and excess moisture. It also improves nutrient use efficiency.

• Other essential nutrients target at each specific crop, ie. Boron for cell wall strength; Manganese for efficient photosynthesis.

• Second chance for a starter fertilizer

• Formulations are targeted at early season root growth (more root = more efficient moisture and nutrient uptake).

• Proactive way of managing the crops nutritional requirement.

• Convey Technology helps with early season stresses such as cool soils, excess moisture, and drought. Also improves nutrient use efficiency.

• Speeds up recovery from herbicide hangover - the correct supply of nutrients helps the crop metabolize the herbicide more quickly.

• Contains novel Phosphorus nutrition, providing increased nutrient uptake and movement within the plant.

• Targeted at the reproductive phse of the plant.

• Proactive way of managing the crops utritional requirement

• Contains other essential nutrients targeted for each specific crop, ie. Boron to aid pollen tube growth, Zinc to help produce Auxin, to ensure healthy pollen tube growth.

Flea beetle feeding on volunteer canola (on left) and yellow sticky traps used to monitor adult beetles (Anitha Chirumamilla, LREC) (P. Beauzay) North Dakota State University CROP & PEST REPORT May 18, 2023 2 If more than 25% defoliation is observed in canola fields, a foliar insecticide spray is warranted to prevent yield loss. Pyrethroids (3A) are the only class of insecticide registered for foliar control of flea beetles in canola (active ingredients - bifenthrin, deltamethrin, lambda-cyhalothrin, zeta-cypermethrin). One premix is labeled as Besiege (chlorantraniliprole + lambdacyhalothrin). For insecticides registered for control of flea beetles for canola, please refer to the 2023 North Dakota Field Crop Insect Management Guide.

Our Fargo 2022 insecticide seed treatment trials against flea beetles examined thiamethoxam (Helix) at 23 fl oz / cwt alone and in combination with cyantraniliprole (Lumiderm, Fortenza), and clothianidin (Prosper) at 21.5 fl oz / cwt alone, in combination with cyantraniliprole (Lumiderm, Fortenza), and in combination with flupyradifurone (Buteo Start) (see Table 1). Flea beetle populations were about 75% striped flea beetle and 25% crucifer flea beetle. For feeding injury ratings, we observed slightly higher feeding injury when thiamethoxam and clothianidin were used alone compared to those same actives in combination with either cyantraniliprole or flupyradifurone. Yield also was significantly higher for the combination of two active ingredients (average of 2421 lbs/acre), compared to the single active ingredient (average of 2123 lbs/acre) and the untreated check (1831 lbs/acre).

National Go Fishing Day

Fly fishing, worm fishing, boating or wading… whatever your preference, get yourself up and out early to catch yourself the biggest fish you can.

The sun is just beginning to rise over the horizon, painting the sky a vivid palette of reds and oranges. The quiet buzz of insects can be heard as they dance over the water’s surface, punctuated occasionally by the splash of a fish breaking the surface for its morning meal, unknowing that it is destined to become a meal itself. National Go Fishing Day celebrates quiet, meditative moments like this and those individuals who find solace in the pursuit of this elusive prey.

We have certainly all fished before. Fished for compliments, fished for some decent wine to go with our Sunday roast but the act of fishing is indeed considered an actual sport.

Whether you fish with the old fashion maggots, or whether you’ve progressed to the corn bait, you will find that fishing in general is a sport that requires both patience and strength. There are plenty of fish to choose from, depending on where you choose to fish and although some people fish for a living, this little hobby can develop into much more than just a Sunday morning past time…

Over-the-counter sale of livestock antibiotics ends June 11, 2023

Beginning on June 11, 2023, over-the-counter antibiotics will no longer be available through traditional retail channels. Instead, these antibiotics will require a prescription from a veterinarian licensed in the state where the animals are housed.

Why is this happening?

To ensure continued effective antibiotic use in humans and animals, the U.S. Food and Drug Administration Center for Veterinary Medicine developed a 5-year Veterinary Stewardship Plan to slow the emergence of antimicrobial resistance from the misuse of antibiotics in animals while ensuring the safe and effective use of medical antibiotics in animals and humans. Many antibiotics are crucial to human and animal health. This legislation ensures that these drugs are used under veterinary supervision, reducing antimicrobial resistance to these drugs in humans and animals. This new rule concerns the few antibiotics that remain available over the counter in the form of injectables, intramammary tubes and boluses.

What does this mean to you?

You will no longer be able to purchase antibiotics from a farm store, mail order, or route driver unless you have a prescription from your veterinarian. Prescriptions must be filled by a pharmacist, but it is unlikely that local Wilco, Coastal or Tractor Supply stores will hire a pharmacist to fill veterinary prescriptions. You will be able to purchase these antibiotics from your veterinarian, or you can use a veterinarian’s prescription to buy from an online vendor. Some local pharmacies will likely carry more veterinary-labeled products. Work with your veterinarian to adjust how your farm will access animal health products. This legislation also applies to nonfood animal species like dogs, cats, camelids and horses.

Which antibiotics will be affected?

Prescription-only items will include injectable tylosin (Tylan injectable and water soluble), injectable and intramammary penicillin (Albadry), injectable and oral oxytetracycline (Liquimycin LA-200, Noromycin 300 LA, Oxytetracycline HCl soluble powder), sulfadimethoxine and sulfamethazine (Albon, Sustain III bolus), gentamicin (Gentamicin sulfate injectable), cephapirin and cephapirin benzathine intramammary tubes (Today, Tomorrow). Most other products — including dewormers, fly preventatives, vaccines and coccidiostats — will not be impacted by these changes.

How will I obtain antibiotics after June 2023?

To obtain these drugs, producers will need a valid veterinarian-client-patient relationship (VCPR) with a licensed veterinarian. A VCPR is considered valid if all of the following apply:

A veterinarian has assumed the responsibility for making medical judgments regarding the health of an animal and the need for medical treatment.

The animal owner or caretaker has agreed to follow the instructions of the veterinarian.

The veterinarian has sufficient knowledge of the animal to initiate at least a general or preliminary diagnosis of the medical condition of the animal.

The practicing veterinarian is readily available for followup in case of adverse reactions or failure of the therapy regimen.

The veterinarian has recently seen and is personally acquainted with the keeping and care of the animal by virtue of examination of the animal, and/or by medically appropriate and timely visits to the premises where the animal is kept. In Oregon, this means that a veterinarian has visited or seen your operation or animals within the past 12 months.

The veterinarian is not required to examine every animal to be treated but has sufficient knowledge of your specific situation to initiate and prescribe treatment.

Should I just stock up on antibiotic supplies?

No! Now is not the time to stock up on over-the-counter
