Effects of Different Peanut Planting Modes on Occurrences of White Grub and Control Effect of Insecticide
摘要
Abstract
To determine the effects of different peanut planting modes (film mulching peanut, opened peanut, straw-returning peanut, wheat peanut intercropping) on occurrences of white grub in spring and summer sowing peanut field and effects of sowing date on control effect of insecticide, the field investigation and insecticide experiment were conducted in both spring and summer sowing pea-nut field.The results showed that higher white grub populations were counted in spring sowing pea-nut field than the summer.Comparing to open planted peanut, film mulching peanut had less white grub populations.The straw-returning summer sowing peanut field had higher white grub populations than no straw-returning treatment.Peanut seed treated with 70% thiamethoxam ZF at 36g AI /667 m2 in the summer sowing peanut field had a good effect on controlling of white grub, the control effect a-mounted to 94.23%.But, it decreased significantly in both early and late spring sowing peanut field, with a 55.36% and 69.23% control effect, respectively.In the early spring sowing peanut field, ap-plication of thiamethoxam by seed dressing + root-irrigation had the best control effect against white grub.The control effect reached 92.04%.Root-irrigation with thiamethoxam could control white grub effectively with control effect of 87.18%.The control effect of using seed dressing was only 55.36%, which was not effective in controlling white grub.The control effect of thiamethoxam was higher than chlorpyrifos through the same application method.Therefore, we recommend that using seeding dressing + root-irrigation against white grub in spring sowing peanut field.While summer sowing peanut using seed dressing methods can be effective against white grub in the whole growth period of peanut.关键词
