Abstract
Abstract ‘Marion’ tomatoes were transplanted July 26, 1976, in 6-ft rows with 20-inch spacing between plants. Treatment plots were replicated 4 times in a randomized block design. Each treatment plot consisted of a single, 25-ff row bordered on each side by an untreated row. The sprays were applied with a D. B. Smith 5-gallon, knapsack, hand-operated, compressed-air sprayer at the rate of 100 gal/A (40 psi) using a D. B. Smith #147 adjustable-cone nozzle. Applications were made on August 30, September 7, 13, 20, 27, October 5, and 13, 1976. In evaluating the various insecticidal treatments, the number of leafminers and number of pinworm mines/10 plants were counted along with the number of potato aphids/10 leaves selected at random and fruitworm-infested tomatoes/100 fruit. All counts were made on October 8. Unfortunately an unseasonably early frost on October 18 (28°F) destroyed so much foliage and fruit that it was impossible to take records thereafter, and the experiment was terminated.
