Abstract
Abstract Plots were direct seeded on Jun 1 at the North Carolina State University Central Crops Research Station, Clayton, NC. Plots consisted of a single row of tomatoes 20-ft long and 3.5 ft wide, separated within rows by 10—Ft of bare ground and between rows by one unplanted row. Overhead irrigation was supplied as needed. Treatments were replicated 4 times in a randomized complete block experimental design. Foliar sprays were applied using a tractor mounted, high pressure sprayer equipped with 3 hollow cone nozzles/row and delivering 60 gal/acre at 150 psi. Treatments were begun when ca 50% of the plants had set fruit. Applications were made weekly from Jul 26 to Aug 30. Sixty randomly selected ripe fruit/plot were harvested on Aug 31, one day after the last treatment, and 60 more/plot were harvested on Sep 6. All were examined for injury by H. zea.
