Dusting with materials containing contain-ing rotenene, which is found in the roots of certain tropical plants has proved to be an effecient conltrol measure for the pea wea-vil. wea-vil. Dusts should be applied at the rate of 20 lbs. per acre, Dr. Knowlton explains. Peas to be harvested while green should be dusted during the two or three day interval be tweeen the time of blossoming and the appearance of the first pods. Dusting must not be delayed delay-ed because loss of the crop may results if the dust is not applied until eggs are laid.
