Abstract
Abstract ‘Ohio 7870’ tomato transplants were planted both no-till and conventional till in 25-ft rows on 15 May ’85 with a 2-row Holland transplanter. The planter was equipped with a chisel in front of each planter shoe for no-till treatments. Plots consisted of 3 rows with the center row being the record row. The distance between rows was 64 inches and the distance between plants within the row was 12 inches. No transplanting was made in overwintered rye. Plots were arranged in a randomized complete block design with 4 replications. The soil was a Norfolk “A” loamy sand. All spray treatments were mixed in 10 gal of water and applied with a custom built row crop sprayer. Each row was covered by 6 drop nozzles delivering 50 gal/acre at 90 psi. Treatments were applied 7, 27 Jun and 3, 18 arid 23 Jul. In evaluating the treatments, direct counts of the number of CPB larvae/10 plants were recorded.
