Insecticide Control Demonstration of Plant Bugs and Effect on Beneficial Spp. , 1983

The objective of this demonstration was to evaluate some of the currently recommended insecticides for plant bug control and to determine if soybean oil (SBOC Standard) is better suited as a carrier of insecticides than water, and to determine the effect on beneficial populations. ‘Delcot 390’ variety cotton was planted 21 May on the Univ. of Missouri Delta Center Lee Farm near Portageville (Pemiscot County), Mo. Eight row plots, 100 ft Long were replicated four times in a randomized complete block design. Insecticides were applied 18 Aug. Water carried insecticides were applied with a four row boom at the rate of 4 gal/acre (5 mph, 30 lb/in2 , One TX-12 cone spray nozzle per row) through an air pressurized system. Soybean oil (SBOC Standard) carried insecticides were applied with a four row boom at the rate of 2.38 qt/acre (8.8 mph, 20 lb/in2 , one Micro max nozzle #20 orifice per row, 2,000 rpm) through an air pressurized system. Twelve ft of row were sampled (drop cloth method) at 1 day, 3 day, and 7 days posttreatment.
