Pre-emergence control of fruit trees in early spring: weeds, deciduous and diseased fruit in orchards, scrape off rough skin and rough skin, trim disease, residue, and dead branches, and then burn or bury it 100 times, can effectively control the occurrence of rot disease. Spreading and inhibiting the wintering propagation of red spiders have obvious effects on the control of powdery mildew, leaf roller insects and scale insects. Post-emergence control: Orchard general spray 150-200 times the 45% crystal lime sulfur or Baume 0.3 degrees lime sulfur plus 50% of 1605 EC 1000 times, can kill more than 90% of the spider mites and in the bud Overwintering powdery spores such as powdery mildew, defoliation, etc. can also control chafers and aphids. Prevention of post-emergence and pre-flowering of fruit trees: spraying 1500-fold 50% 1605 or 80% dichlorvos 1200-1500 times, enemy-killing and pyrethroid pesticides 2500-3000 times, apparently for leaf-eating pests and rot diseases The control effect. After the flowering of the fruit trees, after the flowering of the fruit trees, the lime sulfur concentration of 0.3-0.5 degrees by Baume can be continued to prevent leaf disease and spider mites. Can also spray 2500-3000 times the kung fu, extinction sweep, can not only control the red spider but also kill leaf insects, pest eggs. 10-15 days after flowering, fruit trees can be sprayed with 1:4:20 (copper sulfate: lime: water) Bordeaux mixture or sprayed with 40% carbendazim and 600-800 times of tetrazine, which can effectively control defoliation, anthrax and Brown spot. The use of isocarbohydrate and dichlorvos is strictly prohibited within one month after fruiting.
