Abstract
Seed dressing with insecticides is an effective measure for the control of grubs in peanut field.Field experimental results showed that the control effect of the high dose treatment of 25% Chlorpyrifos CS against grubs was 76.31%~87.80%,and that of the low dose treatment was 58.60%~59.60%.Two different doses treatments of 5% Chlorpyrifos GR increased peanut yield by 17.05% and 21.37% respectively as compared with the check.No matter CS or GR,the control and yield-increasing effects of Chlorpyrifos were better than those of Diazinon and Phoxim.
