Whiteflies (see fig. 3) are very common in soybeans throughout most of the eastern half of Kansas. This is not uncommon, but they seem to be more plentiful this year. However, there is no treatment threshold or even any problems that have been determined from these tiny whiteflies in Kansas soybeans. Potato leafhoppers are also still very common in soybeans where they also never seem to have much impact.

Also, at least for the last week, most soybean fields seemed to have very few defoliators.
