Some insect activity out there, but not much happening yet

Thanks to Nick Zwambag for commenting on here that they are seeing cabbage seedpod weevil activity in winter canola near thamesville earlier this week.  But with this weather, little can be done about it and fortunately the cool temps should slow them down a bit.   Scout once this front goes thro...

More Western Bean Cutworm Damage Being Found

  We visited the Newbury WBC site last week and it was concerning to see so many plants infested with WBC larvae.  There were no external entry holes from the outside of the ear which could fool those who think the ears are clean.  Pay extra attention to those ears that are slightly opened a...

I have been getting more calls this week with people wanting to spray the aphids just to take care of them..even if they are not at threshold.  Most realize that the natural enemies are going to get killed but they also assume 100% kill of the aphids and struggle to understand how the aphids can bu...
