Cabbage Maggot Control, 1982

The plot was planted and treated Jun 15 at our vegetable crops research farm near Geneva, NY in a Honeyoye fine sandy loam soil. Seeds were planted at 10/ft and treatments were applied using cone seeders. Germination counts were made Jul 1. The crop was then thinned to ca 1 plant every 18 in. Plots consisted of a single row, 25 ft long, replicated 4 times in a randomized complete block. Insecticide applications were based on a 36-inch row width. All over-furrow sprays were applied at 50 GPA using a C02-powered sprayer mounted on a cone seeder. In-furrow liquid applications were made with a gravity system mounted on a cone seeder which delivered 50 GPA. Over-furrow treatments were applied in a band 4-inch wide using a hand-pushed Gandy applicator. The band of granules was then planted through, resulting in a slight mixing of the insecticide into the seed furrow. Injury ratings were made Sep 13 by pulling 10 roots/plot, washing them, and counting the number of tunnels present.
