Abstract: ‘Bravo’ cabbage were planted in 1 row plots 35 ft. long on 11 Aug. Plants were spaced 22 inches apart in the row with 72 inches between rows. The treatments were arranged in a randomized complete block design with 4 replications. The soil was a Norfolk A loamy sand. All spray treatments were mixed in 2.0 gal of water and applied with a custom-built row crop sprayer. Each row was covered by 6 drop nozzles delivering 50 gal/acre at 28 psi. Treatments were applied on 31 Aug; 7, 14, 20, 30 Sep; 6 and 14 Oct. Foliage injury ratings ranged from 1-6 and were indexed as follows: 1) no apparent insect feeding; 2) minor insect feeding on wrapper or outer leaves, 0 - 1% leaf area eaten; 3) moderate insect feeding on wrapper or outer leaves with no head damage, 2-5% leaf area eaten; 4) moderate insect feeding on wrapper or outer leaves with minor feeding on head, 6-10% leaf area eaten, head unmarketable during normal marketing conditions; 5) moderate to heavy feeding on wrapper and head leaves and moderate number of feeding scars on head, 11-30% of leaf area eaten; 6) considerable insect feeding on wrapper and head leaves with head having numerous feeding scars, over 30% of leaf area eaten.
