Abstract
Red Norland" potatoes were planted in 25 foot rows on 18 May 92. Plots consisted of a single row treatment. The distance between rows was 72 inches and the distance between plants within the row was 9 inches. The plots were arranged in a randomized complete block design with 4 replications. The soil was a Norfolk “A” loamy sand. Granular treatments were applied with a small shaker can over top the seed pieces in the furrow. In furrow H20 treatments were applied to the seed at the rate of 20 gal/acre with a 2 gal sprinkle can. Initial treatments were applied at planting with foliar spray treatments of Furadan when necessary. Sprays were applied 18 Jun; 3 and 4 Jul. In evaluating the treatments, direct counts of the number of adults, larvae and egg masses/10 plants and the % defoliation were recorded. Defoliation categories were assigned using a pretransformed defoliation rating scale, based on dividing 90° into 13 steps corresponding to arcsin transformation values (Little & Hills 1978). Yields were taken on 3 Aug from 25-ft row.
