Abstract

The invention discloses a comprehensive control method for diseases and insect pests of Chinese chestnuts. The comprehensive control method comprises four control measures of plant quarantine, physical control, biological control and chemical control, wherein the physical control comprises scientific cultivation and management, manual capturing, trapping and killing, tree disk ploughing, tree trunk whitening and garden cleaning in winter; and the biological control comprises the following steps: planting nectariferous plants in the chestnut garden, and attracting chestnut parasitic wasps and predatory natural enemies; raising chickens or pigeons in the chestnut garden in a stocking mode, or attracting beneficial birds into the forest; planting corn, sunflower or cotton around the chestnut garden; applying biological pesticide; and applying insect hormones. The method follows the principle that prevention is dominated and comprehensive control is carried out, chemical pesticide reduction is taken as the purpose, the four control measures including plant quarantine, physical control, biological control and chemical control are adopted, Chinese chestnut diseases and insect pests can be effectively controlled, the yield of the Chinese chestnuts is increased, the quality of the Chinese chestnuts is improved, and economic benefits are improved; and the pesticide used for chemical control is a high-efficiency, low-toxicity and low-residue mineral source pesticide and has good environmental compatibility.
