Abstract
The carrot rust fly (Psila rosae) is now fairly well established in northern and n.-w. Oregon. 1944 tests with DDT (3% Geigy) dust in small replicated plots have shown promising control of the carrot rust fly when used as a dust at the rate of 8 ounces per 30-ft. row or as a seed treatment at the rate of 2.5 lb. per 180-ft. row.This publication has 0 references indexed in Scilit:
