Apple plant pest prevention and control should implement the "prevention-based, comprehensive prevention and control" plant protection policy, based on agricultural and physical control, biological control as the core principle of prevention and control, scientific use of chemical control technology, effective control of pests and diseases. We will vigorously promote unified defense and improve the effectiveness of pest control. It is worth mentioning that the unified defense rule must adhere to the "four unifications", that is, the unified technological plan, unified forecasting, unified time, unified medication.
Major diseases and insect pests: Major diseases: rot, anthracnose, brown spot, ringworm, deciduous, powdery mildew, black spot, root rot; main pests: borer (Pinomyces pulcheralis, P. minor) Leafhoppers, gold moths, chafers, locusts, etc.
Agricultural control measures include the removal of pests and branches, the removal of litter, the scraping of cracked trunks of tree trunks, the turning of tree trays, the covering of ground stalks, the weeding of orchards, the application of scientific fertilization, and the removal of pests and fruits to prevent pests and diseases.
Physical control According to the biological characteristics of pests, pests may be hunted using methods such as sweet and sour liquid, tangled grass rope and black light.
Biological control Artificial release of Trichogramma, assisting in the movement and protection of natural enemies such as ladybugs, grasshoppers, predators, etc., applying Beauveria bassiana to the soil to prevent peach borer pests, using insect pheromones to trap or disturb adult mating.
Chemical control The whole park inspected and scraped the rot. The wound was smeared with 100% of 2% bacteria. Spray once a week after flowering, 3% polymycin, dilution of 800-1000 times. Spray 2% of gram of gram g once, dilution 200-260 times. The main prevention and treatment of defoliation, and prevent powdery mildew, black spot disease. In mid-July, 2% of the bacteria were sprayed with poisonous grams and the dilution was 200-260 times. In early September, 3% polymyxin was sprayed and the dilution was 800-1000 times. The main prevention and control of anthrax, ring disease, and prevent black spot disease.
Pest control In mid-August, sweet vinegar or trapped turtles were used to kill the scarab. During the dormant period of deciduous leaves, the diseased shoots, rotten fruit, and defoliants in the garden are burned or buried deeply.
