Control of Soybean Insects at Mississippi State, MS, 1985

This test was conducted on the North Plant Science Farm at Mississippi State, MS. Test plots were 6 rows 40 inches wide and 50 ft long replicated 4 times in a randomized complete block design. One sample was taken from each plot. A sample consisted of the insects collected by 25 sweeps of a 15-inch sweep net. The contents of each sample were transferred to paper bags killed and counted under laboratory conditions. Insecticide applications were made on 21 Sep, at 5 gal/acre. At this time the soybeans were in the late pod fill stage and some leaves were senescing. Four rows of the plot were sprayed using a 4-row spray boom mounted on a Hi-Boy with 2 nozzles/row using CO2 as a spray propellent. This test received 0.63 and 0.12 inches of rainfall on 22 and 23 Sep respectively.
