Monitoring the Pesticide Treatments of the Japanese Beetle Project, Sacramento County, California, 1983-1986. Volume 1: Carbaryl

摘要

The Japanese beetle has the potential of being a serious agricultural pest if it becomes established in California. Therefore, the Sacramento County Agriculture Department and the California Department of Food and Agriculture conducted a program to eradicate an infestation found in the Orangevale area. The program was initiated during the summer of 1983 and continued through the spring of 1986. One phase of the eradication program consisted of multiple applications of carbaryl to foliage during each of the three summers for 1983, 1984, and 1985. Carbaryl concentrations resulting from these Japanese beetle treatments were similar to those seen during gypsy moth programs. No accumulation of residues from one application to the next was observed, even when applications were four to nine days apart. Off-target movement of carbaryl was low as measured by the amount discharged in runoff and drifting into an adjacent water body.
