T/ZWAZJSXH 005-2024 Apple Green Prevention and Control Technical Regulations for Main Pests and Diseases and Injurious Animals

Scope

Main Technical Content: Green Prevention and Control Techniques for Major Diseases and Pests of Apples 5.1 During the dormant period from December to early March of the following year, adopt agricultural prevention measures such as reasonable pruning, clean-up of orchards, and protection of wounds to reduce the overwintering population of diseases and pests in orchards and enhance tree vitality. 5.1.1 Rational pruning: Conduct scientific shaping and pruning of apple trees to improve ventilation and lighting conditions in the entire orchard and enhance their disease resistance. Pruning shall comply with NY/T5012 and DB14/T748. 5.1.2 Clean-up of orchards: During the dormant period, remove diseased and residual branches, fallen leaves, and dropped fruits, take them out of the orchard and destroy them centrally. At the same time, remove the insect-attracting strips tied to the base of the trunk in the previous autumn and burn them centrally to reduce the source of pathogens and pests in the orchard. 5.1.3 Protection of wounds: Apply protective agents to pruning and sawing wounds with diameters exceeding 1cm to prevent diseases, pests, and frost damage. Common protective agents include white emulsion paint, waterproof paint, lime milk, and methylthionyl methane paste. 5.2 From budding to flowering (March to early April), adopt measures such as grass cultivation in orchards, scraping off diseased spots, and spraying the entire orchard to reduce the early spring population of diseases and pests in orchards. 5.2.1 Grass cultivation: Plant white clover, flat-stemmed Astragalus, alfalfa, and creeping clover in the rows between apple trees to improve soil fertility, enhance ecological conditions in the orchard, and increase the number of natural enemies and their populations. When sowing, level and loosen the soil, and shallowly plant the seeds in rows with a depth of no more than 5cm. When the grass reaches a height of 30cm, mow it promptly, leaving a stubble of
