Soybean Aphid Scouting and Management
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.
Soybean Aphids Found in Northeast Nebraska; Scouting Warranted
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.
Decision Making for Soybean Defoliating Insects
