Soybean Aphids Still Low (08/16/18)

Soybean Aphids Still Low

Hot weather has decreased the risk of economic soybean aphid infestations, and soybeans are maturing quickly. The crop stages of soybean ranged from R4 (full pod set) through R6 (full seed set) crop stages, so in some areas we are at the R6 (full seed set) crop stage where there is minimum impact on yield from soybean aphid feeding injury. It looks like most soybean fields escaped damage from soybean aphids in ND! Good news for soybean producers.

Continue to scout for soybean aphid populations, especially in any late-planted soybeans.
