Control of European Corn Borer and Green Peach Aphid on Peppers, 1992

Peppers were transplanted on 30 Jun at the Eastern Shore Agricultural Experiment Station, Painter, VA. Each plot consisted of a double 25 ft row bordered on each side by an untreated guard row, replicated 4 times in a randomized, complete block design. Plant spacing was 12 inch with 36 inch between rows. Sprays were applied with a propane compressed-gas backpack sprayer using 3 hollow cone nozzles per row and delivering 60 gal water/acre at 40 psi. Applications were made weekly beginning 5 Aug through 28 Sep. Triton AG-98 (4 oz product/acre) was added to each treatment. Kocide (12 lb product/acre) and Maneb (2 lb product/acre) were applied weekly to control bacterial spot. Evaluation criteria consisted of harvests of all market-sized fruit per plot. This fruit was graded as either marketable (no insect damage) or worm-damaged. On 29 Sep stem holes from ECB feeding were counted on 10 randomly chosen plants per plot. The number of GPA on 25 leaves per plot was recorded on 5 Oct.
