Control of Armyworm and Pepper Weevil on Bell Pepper, Fall 1996

Abstract

Abstract Transplants were set 6 Sep, 12 inches apart on 8-inch-high and 32-inch-wide beds of EauGallie fine sand covered with white polyethylene mulch. Each plot consisted of a single row of 12 plants with rows on 5-ft centers. Treatments were replicated 4 times in a RCB design and were applied with a 2.5-gal, hand-held CO2-powered sprayer on 25 Sep, 2, 9, 16, 23, 30 Oct, 6, 13, 20 Nov, 4, 11, 18, and 23 Dec. The sprayer was outfitted with a single nozzle with a D-5 disk and #45 core and delivered 100 gpa at 60 psi. Fruit were harvested on 12, 25 Nov, 10, and 30 Dec and the number and weight of undamaged fruit and the number of fruit damaged by beet army-worm larvae were determined. Fruit with damage only on the fruit petiole or calyx were considered marketable and fruit with pod damage were considered unmarketable. Fruit also were examined for the presence of oviposition scars on the outsides of the fruit and for the presence of larval feeding damage on the insides of the fruit caused by the pepper weevil.
