The young fruit period is the most critical period for the prevention and control of apple pests and diseases. This period is mainly used to control ring rotten rot disease, gold-grained moths, maggots, and calcium deficiency diseases. It also protects against spotted defoliation, black spot disease, apples Astragalus membranaceus, apple aphid, leaf roller moth, borerworm, cornel mealybug and so on. Specific measures include ten aspects.
1. From 7 days to 10 days after flowering, spray 80% of Gotemali WP 800 to 1000 times or 80% of Dasong M-45 WP 800 to 1000 times continuously for 1 or 10 days. , Even spray 3 to 4 times, keep the leaves and protect the fruit.
2. After flowering and before wheat harvest, spray 15% 25% diflubenzuron suspension agent 1500-2000 times, 20% L-urea suspension agent 4000-fold, or 30% mothalidone WP 2000-times. , Prevention of gold moths.
3. Before and after flowering, it is the key period for the control of hawthorn leafhoppers. The end of May and early June is the key period for the control of two leaf-filled spiders (white spiders) and spider mites. The use of 9.5% chlordiazepoxide to kill 2000 times ～ 2500 times liquid and avermectin pesticides to control the red spider and the two-spotted spider mite are effective. The scorpion type pesticide only has good control effect on spider mites.
4. After spraying 3, 4 and 5 weeks, spray 1 quick-acting calcium 500-600 times or high-efficiency calcium 500-600 times to prevent calcium deficiency.
5. It is effective to control apple astragalus with 48% Leosmian EC 1000-1500 times, 52.25% CAI 2000- 2500 times, and 10% imidacloprid wettable powder 2500 times.
6. Use 20% Suspending Agent 3000-4000 times, 48% Leosmother Emulsion 1000-1500 times, 52.25% Fertilizer 2000- to 2500-fold and 30% Tao Xiao-Ling 1500-fold Such as control leaf roller moth good effect.
7. From late May to early June, two or three days after the rain, sprinkle phoxim granules on the ground, use 2 kg to 2.5 kg/mu, or spray 48% of Le Siben, 0.5 kg/mu, on water. 200 times to 300 times, prevention and treatment of overwintering Peach borer.
8. There are apple orchards in the orchard, spraying 48% of Loester EC 1000 times to 1500 times the liquid for prevention and control of apple astragalus.
9.Before apples must be sprayed once 80% of WP WP 800 times, or 80% of DM M-45 WP 800 times +48% of LS, 1000-1500 times, or 52.25 % Farmland is 2,000 times to 2500 times the amount of cream, prevention and treatment of bagging black spot disease and Cornell mealybugs, and prevent rotten fruit rotten disease, roller leaf moth and so on.
10. Addition of pesticide spreading agents or auxotrophic pesticide synergists can significantly improve the control effect when controlling gold-grained moths, aphids, red spiders, and two-spotted spider mites.
1. From 7 days to 10 days after flowering, spray 80% of Gotemali WP 800 to 1000 times or 80% of Dasong M-45 WP 800 to 1000 times continuously for 1 or 10 days. , Even spray 3 to 4 times, keep the leaves and protect the fruit.
