Effect of Insecticides on Squash Bug Oviposition on Squash Interplanted with Other Vegetables, 1981

Abstract

Abstract ‘Early Prolific Straight Neck’ summer squash was planted on Jun 4 at Virginia State University’s Randolph Farm, Chesterfield Co., VA. Soil type was a Goldsboro fine sandy loam. The field plots were arranged as a randomized complete block design with 4 rows, each 10-ft long. Squash was planted in one of these rows while col lard, pepper and eggplant were planted in the remaining 3 rows. These plots were replicated 4 times with 5-ft alleys between plots. Squash was treated 2 wks after planting with a piston pump sprayer mounted with a single hollow cone nozzle. Spray solutions were prepared at the rate of 100 gallons/acre. Spraying was initiated on May 20 and was continued at biweekly intervals thereafter. Spraying was concluded on Aug 12 with a total of 7 sprayings. Three plants were uprooted from each treatment on Aug 10, two days before the 7th spraying and eggs were counted on a leaf by leaf basis. Similar data were taken on Aug 20, one wk after the 7th spraying.
