Control of Fruitworm and Pinworm on Tomato, 1977

The test conducted at the North Alabama Horticulture Substation, Cullman, Alabama. Seedlings were transplanted on July 13. Plots consisted of 3 rows (88-inch centers) X 40 ft and were separated by 5-ft alleys. Plant spacing on the rows was 18 inches. A randomized complete block design with 4 replications per treatment was used. To prevent fruit rots, Manzate 200 (at 2 lb ai/acre) was applied weekly through September 9, then Difolatan (at 2 lb ai/acre) from September 16 through October 7. Test insecticides were applied at weekly intervals from August 27 through October 7 using a Super Blue Boy 6000sprayer delivering 50 gal/acre. Data were taken from the middle rows. Damage to fruit by fruitworm and pinworm was determined by harvesting and examining all rotting and ripe fruits weekly from September 15 to October 13 and all ripe and mature green fruits on October 20. Data from all harvest dates were pooled for statistical analysis.
