Abstract

Soybean aphid populations have increased dramatically in fields across the state with growing populations noted in central, western, and northwest counties. Populations may be peaking in eastern and northeastern county fields. Numbers now being reported in some fields have exceeded 1,000 to 2,000 aphids per plant. With numbers like this on R2-R4 stage plants, economic losses are likely and treatments are merited in most cases.
