Fruit and pest control measures in early spring fruit trees In winter orchards, pests and diseases have entered lurking winter. At this time, the pests did not have the appearance of appearance, coupled with the lack of understanding of the hard-working farmers for a year, gave up a perfect opportunity for prevention and control, and created opportunities for the occurrence of diseases and insect pests in the coming year. To grasp the characteristics of overwintering in orchard pests and diseases, and to adopt comprehensive measures such as agricultural control, physical control, and chemical control in light of local conditions, special attention should be paid to the first application of pest control in early spring. The object of pest control in early spring orchards is: rot, dry rot, powdery mildew, rough skin disease, rotten fruit rotten disease, and scale insects, apple aphid, aphids, and leafhoppers. In other words, insecticides should not only consider both insects and cockroaches, but also have certain wax-soluble properties, that is, they have a strong contact effect on scale insects and certain eggs and egg masses; fungicides must not only have a broad spectrum of sterilization. Spectrum, that is, a drug treatment of many diseases, and there must be internal suction conduction, in order to ensure that even in the buds of fruit trees can still exhibit excellent bactericidal effect. In addition, most insecticides and bactericides are sensitive to alkaline substances, and in production, dilution of pesticides with alkaline water can be found everywhere. It is recommended to use the high-tech product, Sanitary Water, manufactured by Singapore Linon Company, for dispensing. Optimize water quality for agricultural use, increase adhesion, increase permeability, and give full play to efficacy. The result of the 2006 Xi'an Fruit Friendship Association's test in the northwestern apple production area shows that in the early spring orchards, once sprayed by Jin Luxi 5000-6000 times + An Minle 800-1000 times + Roushuitong 3000-4000 times, it can effectively kill the latent. The pathogens and apple aphids, aphids, and scale insects greatly reduced the pests and diseases of the year. It is worth mentioning that once a latent rot disease breaks out, it will cause great harm. The light will cause the tree vigor to weaken, the yield will be seriously reduced, the fruit will be small, and the quality will be poor. In severe cases, the tree will die and even the orchard will be destroyed. According to experiments in apple, Shaanxi, Gansu, Shanxi, Hebei and Henan provinces, 400-500 times of Roushuitong, 200-300 times of Guinness and 1,000 times of Steadcope are used, and the mixed solution is either cut or scraped. Smear spots, have extremely excellent control effect, and low cost. At the same time, it is recommended to scrape and treat lesions, use plastic sheeting to tile under the tree plate, after the end of the curettage, use plastic sheeting to collect lesions and burn them. It is necessary to pay attention to the early spring prevention and control of orchards, reduce the incidence of diseases and insect pests in the year, and strengthen the tree vigor so as to increase production and income.
