Abstract
Two tests were conducted to determine efficacy of foliar-applied insecticides against a stink bug complex in soybean. ‘USG 74B58’ soybean was planted on 10 May 2012 on a private farm in Goochland, VA, using 7.5-inch row spacing. A randomized complete block experimental design was used with 2 replicates; plots were 6 ft by 30 ft. Treatments in both tests were broadcast on 28 Aug with a CO2-pressurized backpack sprayer at 14.3 gpa and 18 psi through four 8002VS nozzles spaced 18-in apart on a 6-ft spray boom. Efficacy against the stink bug complex was determined at multiple days after treatment (DAT) by taking 15 sweeps/plot with a standard 15-in diameter sweep net and recording the number of nymphs and adults for BMSB, GSB, and BSB (totals for the species are reported). Data were analyzed using ANOVA and LSD statistical procedures.
