If the winter and spring are cold and rainy, the chafer is less harmful, and the chestnut blight is more serious. In the rainy days in July, the pruning weevil and the red spider (the chestnut small catching) occur lightly. Chestnut paste disease and anthrax occur more seriously.
In July, the peach amaranth, chestnut snow flakes, and anthracnose caused similar symptoms to chestnut damage. First, some stinging deaths gradually expanded, and later, the chestnut cracks and fell.
In recent years, excessive use of boron fertilizer and spraying of organophosphorus pesticides have led to poisoning of chestnut leaves, shrinkage of chestnut leaves, curling, chlorosis, redness of leaf margins, and large loss of chestnut leaves. This situation is more common. The masses mistakenly believe that pests and diseases are blindly controlled and increase the degree of damage to chestnut trees.
Comprehensive prevention:
1. Manual removal: In April, the chestnut pumping new shoots, if there is a tumor, can be removed at any time, which can alleviate the damage of the chestnut bee in the same year and the coming year. From mid-July, it will be picked up 10 to 15 days apart until the chestnut harvest is over. Picking up the chestnuts and burning them. The pruning weevil, from mid-June to late July, removes the chestnuts that fall off the surface at 5 to 7 days and concentrates on burning, all of which can alleviate the pests of the coming year.
2. In addition to the scorpion complex: Mao Li is a pruning weevil, chestnut snow flake elephant, another host of chestnut food weevil, clearing the chestnut within 500 meters of the chestnut garden. In winter, the chestnut garden reclamation and destroying the wintering place of pests can alleviate the above pests.
3. Change the improved varieties: susceptible to susceptible insects such as early-maturing dihydrate, the yield is unstable, and can be changed to Dahongpao, sticky floor, Yeli chestnut and other high-quality, high-yield, stable production, insect-resistant and disease-resistant varieties.
4. Physical control: Chafer, peach aphid, and beetle have strong phototaxis. They can be trapped by black light or ordinary lighting. The light is set on the slope of 50~100 meters away from the chestnut garden, behind the house or on the side of the road. The light time is from 8:00 to 10:00 in the evening, and the lure is from early April to mid-May. The trapping effect is better than pesticide control.
5. Scientific use of drugs: chafer, pruning weevil, peach aphid and other fruit, leaf-eating pests can use high-efficiency cypermethrin, trichlorfon, oxymatrine and other pesticides. High-efficiency, low-residue insecticides and acaricides such as arsenic, imidacloprid, and acetamiprid are used for sucking pests such as chestnut, chestnut, and spider mites. Chestnut anthracnose and chestnut blight are selected from copper preparations, agricultural anti-120, methyl thiophanate, carbendazim and other fungicides. A diesel emulsion for controlling chestnut plaster.
