Aphids at low levels in soybean fields in the London area have been evident since Thursday June 17th.These shots taken near Thamesford Ontario on Wed June 24 show aphid colonies in the hundreds on newly developed soybean leaves.There is no economic threshold level currently established for the early vegetative stage of soybean growth.As you can see the above soybeans were at the second true trifoliate leaf stage.U of G are currently attempting to determine what the vegetative threshold level should be. The hope is that natural predators will begin building their populations and draw down these aphid numbers.We will keep you informed as to what unfurls in this regard.
