This week soybean aphids were found in several northeast Nebraska fields at low numbers. Although it has been too hot for soybean aphids to thrive, populations could quickly increase with cooler temperatures. Scouting is recommended at this time.
The current recommended economic threshold for late vegetative through R5 stage soybeans is 250 aphids per plant with 80% of the plants infested and populations increasing. Depending on economic conditions, this generally gives you about five to seven days to schedule treatment before populations reach economically damaging levels.
July is when growers start to see a variety of defoliators in Nebraska soybean fields. It's easy to overestimate the amount of defoliation and soybean plants can compensate for some leaf area loss. This article describes how to assess defoliation and provides basic treatment thresholds.
While soybean defoliation, the most common injury to soybeans from insects, can look devastating, soybean plants can often compensate for the leaf loss. When making pest-management decisions, crucial considerations are the size of the remaining leaf canopy and the soybeans' growth stage.
