In recent years, the control study on the control of chestnut borer in five plots of state-owned Mengliangtu forest farm found that the control of chestnut borer by the first half of June before using 25% phoxim per kilogram of 667 square meters plus 150 kilograms of water Sprayed under the canopy, can kill unearthed larvae, and then applied 25% chlorbenzuron 3 suspension 1000 times in mid-July tree spray, mid-August sprayed 21% of trees killed 2500-3000 times Liquid, the best, can increase the yield of 38%, chestnut beetle for the prevention and treatment to provide materials and basis, in order to find the best method of prevention and control of chestnut borer.
