Reports are coming in late last week of fields in Eastern Ontario reaching well above threshold levels for soybean aphids. Just a few weeks prior, these fields had only 30 to 40 per plant.

Late Planted Soys at Risk of Soybean Aphids?
I've been pondering our planting situation lately and what impacts it is going to have on some of our key insect pests. We've been anticipating this year to be a good soybean aphid year for Ontario.

It hasn't been since 2002 that we have experienced this low of levels of soybean aphids. Cross my fingers and knock on wood but I think we are going to get through the season without a problem.
That said, spidermites are starting to pop up in fields, particularly where it is starting to get a bit... Continue reading

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... Continue reading

A recent summer migration of soybean aphids in Ontario has resulted in many new fields having a fair number of aphids in them now. Fields that were scouted a week or two ago and were found to have very few aphids could now be closer to threshold than you think. Scouting is advised. Scout Cruis... Continue reading

SPIDERMITES: I have a sneaking suspicion that spidermites are making their way into those fields that haven't had rain in a while. We have had situations in the past where not only have they popped up in soybeans and were being disregarded as "drought stress" symptoms but also in seed corn, espec... Continue reading
