Abstract
Abstract Transplants were set on 16 Jun at the Mountain Horticultural Crops Research Station, Fletcher, NC. Plants were set two ft apart within 20 ft rows and rows were on 10 ft centers. Single-row plots were arranged in a randomized complete block design with four replications. Materials were applied on 13, 20, 29 Jul, 8, 19, 29 Aug and 12 Sep with a tractor-mounted boom sprayer delivering 55-125 gpa (gpa increased as plants grew) through 7 hollow cone nozzles per row (three on each side and one overhead). The Dipel, Xentari and Mattch treatments also received the experimental aphicide RH-7988 on 8 and 29 Aug, and the Kryocide treatment received RH-7988 on 8 Aug. PA populations were monitored on 14, 21, 28 Jul, 4, 11, 19 and 31 Aug by observing 10 leaves (3rd most recently expanded leaf) per treatment and recording the number infested with > 1 apterous aphid. FT were monitored twice during the season on 22 Jul and 12 Aug by counting the total number of thrips on 10 flowers per treatment (40 flowers total per 4 reps). Fruit was harvested on 22 Aug, 2, 9, 16, 23, and 28 Sep and those damaged by SB, TFW, and FT were recorded. All data were analyzed using a two-way ANOVA, and means were separated using LSD (P = 0.05).
