Abstract
Abstract 'Votes' collards were direct seeded In 3-ft rows on Jun 13 and thinned to 10-in spacing 1 month later. Treatment plots were replicated 4 times and arranged In a randomized block design. Each plot consisted of a single 30-ft long row with an untreated row adjacent to each treatment plot. The sprays were applied with a D. B. Smith 5-gallon, knapsack, hand-operated, compressed-air sprayer at the rate of 100 gal/acre (40 psi), using a D. B. Smith #E-147 adjustable cone nozzle. A single application was made on Sep 16. Treatments were evaluated by counting the number of flea beetles per 10 sweeps with a 15 inch diameter insect net at 3, 24 and 96 hours after treatment.
