O.S.R. pollen beetle 2019

Try not to look in the crop mid afternoon on a hot still day, as that's when numbers are highest. Look again on a windy evening and you'll see less, so will make the more environmentally friendly decision not to treat!

Note my wording about environmentally friendly, not crop friendly... A large % of pollen beetles are resistant to pyrethroids, so for no major decline in beetle yet a far bigger decline in future pollinators needed next week when that plant comes into flower will leave you net worse off. Try not to spray insecticides please, people. Excessive use of pyrethroids is why we're in this mess of resistance in the first place.

I’m of the same thought process, that’s why I posted to make myself feel better! Gone away from the farm today so they’ll be left to it...

Should we all plant a few percent of seeds of a very early flowering variety as a cultural controll ??

Is anyone spraying for pollen beetle? I had to treat some to save my crop a week or two ago. Some main heads had up to 5 buds remaining and laterals were getting hit before pushing out. I have never sprayed for them before and now am forced to do it again! I had 90+ beetles per plant, before last app. Now numbers building again and severe damage caused yet again. This is only on my campus. Everything else is further ahead and in full flower.
