Insect Control on Tomato in Southwest Florida, Spring 1984

Transplants were set 16 Feb, 18 inches apart on 3-ft wide by 6-inch high beds of Immokalee fine sand covered with black polyethylene mulch. Plots consisted of 10 plants and treatments were replicated 4 times in a randomized complete block design. Treatments were applied 8, 15, 22 Mar, 2, 6, 12, 19 and 26 Apr with a 2.5 gal hand-held CO powered sprayer which was operated at 40 psi and delivered 40-120 gal/acre (gal increased as the plants grew). On 9 May, the no. of small and large leafmines (those either less than or greater than 0.5 inch in length, respectively) were counted on the terminal 3 leaflets of 10 branches per plot. The no. of undamaged fruit and those damaged by lepidopterous larvae (principally the southern armyworm and tomato pinworm) and stink bugs were counted in a single harvest on 11 May.
