An investigation on the combined effects of cultural and chemical control of damage by the carrot rust fly, Psila rosae (F.), showed that marketable carrots could be grown even without chemicals in S. W. British Columbia provided they were sown alter March 30 but before May 13 and harvested within 100 days of seeding. Carrots sown after April 14 and left in the ground more than 100 days were subject to heavy damage by second-generation carrot maggots. Carrots sown on April 1'4 and treated with organophosphate or organocarbamate insecticides applied in the seed furrow, as drenches, or in the furrow supplemented with drenches, suffered little or no damage up to 100 days alter seeding. However, of 9 insecticides tested only Bayer 25141 [O,O-diethyl O-p- (methylsulfinyl) phenyl phosphorothioate] prevented damage by the sec- and generation of maggots. Zinophos®, (O,O-diethyl 0-2- pyrazinyl phosphorothioate) was somewhat less effective and the rest were ineffective. All were phytotoxic in some degree In the seed furrow.
