Abstract
Abstract Transplants were set 8 Sep, 15 inches apart on 8-inch-high beds of Eau Gallie fine sand covered with white polyethylene mulch. Each plot consisted of a single 15 ft row with rows on 5-ft centers. Treatments were replicated 4 times in a randomized complete blocks design and were applied with a 2.5 gal, hand held CO2-powered sprayer on 17, 24, 31 Oct, 7, 14, 21, 28 Nov and 5 Dec. The sprayer was operated at 40 psi and the gallonage was increased as the plants grew. Thus, the sprayer delivered 90 gal/acre on the first spray, 105 gal/acre the next three sprays, 115 gal/acre the next three sprays, and 120 gal/acre for the final spray. The sprayer had a single nozzle fitted with a D-5 disk and #45 core. Fruit were harvested on 7 Dec and the numbers and weight of undamaged fruit and the numbers of fruit damaged by noctuid larvae (primarily the southern armyworm, S. eridania (Cramer) were determined.
