Abstract

California Brussels sprout growers, lacking adequate sampling techniques to determine economically significant damage by insects, historically have applied preventive sprays of pesticide combinations after each irrigation (approximately every 18 days). An average of 19 pounds (active ingredient) of insecticides per acre were applied by growers in 1981.
