Abstract
SUMMARY Trials were done in eastern England in 1972–74 to study relationships between control of wheat bulb fly larvae and amounts of insecticide on treated seed. Carbophenothion in short‐row trials in 1972–73 was relatively ineffective even at the largest dose, 100 μg/seed. Chlorfenvinphos at low dosages did not significantly decrease the percentage of plants with live larvae but was increasingly effective as the dosage increased. Dieldrin decreased the percentage of plants with live larvae even at small dosages, about 10 μg/seed. Clilorfenvinphos was further studied in larger plots (c. 0.01 ha) in 1973–74. Plant examinations confirmed results of the previous year but large yield increases were obtained at only two of four sites, one with the greatest plant attack (55 per cent damaged shoots) and the other with the latest sowing date (22 November).
