Tomato Fruitworm Control on Fresh Market Tomatoes, 1981

This test was conducted at the North Alabama Horticulture Substation, Cullman. Tomato transplants were set on Jun 13. Plots consisted of 3 rows, 25 ft long (88-inch centers), with 5-ft alleys. A randomized complete block design with 4 replications per treatment was used. Sprays were initiated when fruit began to set. All applications were made with a Super Blue Boy 6000 high clearance sprayer. Treatments were applied on Aug 5, 12, 26, Sep 2, 9 and 27. For disease control, Manzate 200 (at 1.6 lb ai/acre) was applied early in the season and Difolafan (at 1.0 lb ai/acre) was used late in the season. Tomatoes were harvested 5 times (Aug 25, Sep 1, 8, 16 and 23). Damage and yield data were taken from the middle row of each plot. All fruits were examined visually, and dissected when necessary, to determine damage by the fruitworm.
