Abstract
Various rates and methods of applying organophosphorus and organocarbamate insecticides were compared in peat soil and sandy loam, against cyclodiene-resistant cabbage maggot, Hylemya brassicae (Bouché), in rutabaga. Phototoxicity and lack of persistence of single applications of the compounds at seeding caused initial problems. Granules applied at reduced rates in the furrow or as bands at seeding or a drench over young seedlings overcame the phytotoxicity. Three supplementary drenches during the growing season counteracted the lack of persistence of the pesticides. NIA.10242, an organocarbamate, was the most effective insecticide in sandy loam, and Zinophos, an organophosphorus compound, in peat soil. The best interval for the three supplementary drenches, starting 28 days after seeding, was 3 weeks.Keywords
