Cabbage Looper Control on Lettuce, 1978

Four applications were applied during Oct (11, 17, 24, and 31) with a 2.5 gal backpack CO2 pressurized hand sprayer equipped with a 6-nozzle boom operated at 40 psi. Treatment plots were replicated 4 times and arranged in a randomized block design. Each plot consisted of a 42-ft row with an untreated guard row on each side. Results were meas measured by egg and larval counts on 10 plants from the middle of the plots. Counts were made 4 days after each treatment and a final count 10 days after the 4th application.
