Control of Armyworms and Pepper Weevil on Bell Pepper, Spring 1997

Abstract

Abstract Transplant were set 10 Mar, 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 14 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 2, 7, 14, 21, 29 Apr, 5, 19, 27 May, 2, 11, 18, 25 Jun, 2 and 9 Jul. 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 21 May and 9 Jun. The number and weight of undamaged fruit and the number of fruit damaged by armyworm larvae were determined. Fruit also were examined for the presence of oviposition scars on the outsides of the fruit and for the presence of larval feeding damage caused by the pepper weevil inside the fruit. On 14 Jul, all fruit were harvested and examined for the presence of oviposition scars and internal pepper weevil damage.
