ResumoAbstract Seedlings of ‘K-K Cross’ cabbage were transplanted 29 Mar, in a soil classified as clayey, gibbsitic, nonacid, isohvperthermic Lithic Ustorthents in Barrigada, Guam. Each plot consisted of 5 rows with 12 plants/row. The distances between rows and between plants within a row were 120 cm and 46 cm, respectively. Experimental design was a randomized complete block with 4 replicates. Treatments were applied with back-pack sprayers on 12 and 27 Apr and 6 and 16 May. On 20 May the percentage of plants with various insect damage was examined by observing 30 plants/plot. Insect damage rating was estimated on a 1-5 scale (1, no insect damage; 2, 25% insect damage; 3, 50% insect damage; 4, 75% insect damage; 5, 100% insect damage). On 23 May 20 heads/plot were harvested and weighed to determine yield.
