Use of Furadan 4F for Striped Cucumber Beetle Control in Spring Cucurbits, 1993

Cucumbers were planted on 10 Jun at the Eastern Shore Agricultural Experiment Station, Painter, VA. Each plot consisted of a 25 ft row bordered on each side by an untreated guard row, with 5 ft row spacing. Plots were replicated 4 times in a randomized complete block design. Furadan 4F treatments were applied with a single nozzle boom backpack sprayer in furrow immediately prior to planting. Foliar sprays were applied on the dates indicated in the table in 45 gal water/acre at 40 psi. A single nozzle boom was used for the first spray, and a three nozzle boom for subsequent sprays after the vines had begun to run. Evaluation criteria consisted of insect counts on 6 feet of row, and ratings of percent defoliation and bacterial wilt. The entire 25 ft row of each plot was harvested on 21, 26, and 30 Jul, and 3 Aug. SCB was the dominant insect species present, with low numbers of squash bugs and spotted cucumber beetle also present.
