Control of Tomato Fruitworm on Tomato, 1978

The test was located at the Agricultural Experiment Station in Inarajan, Guam. Seedlings were transplanted into the field (volcanic ash with a Mariana limestone base) on Dec 15, 1977. Each plot consisted of 3 rows 12 ft long and 5 ft apart. Each row consisted of 7 plants. Plants were grown to 5 ft tall on suspended strings. A randomized complete block design with 3 replications was used. There were 3 treatments plus a control. Treatments were applied starting on Feb 10, 1978, and continued every 4 days until Apr 19. All tomatoes formed prior to Feb 10 were removed so all fruit would be treated. Fruitworm damage was assessed by examining all immature fruit on the plants on Feb 23, Mar 30, and Apr 27, recording damaged vs. undamaged. All ripe fruit were harvested throughout the production of the plant and recorded as damaged or undamaged.
