Every kind of fruit tree is different, even big trees and small trees are different. Different areas have different control targets.
The main common pathogens of apple trees are: defoliation (including: spotted deciduous, brown spots, round spots, etc.), and fruit damage is anthrax and mold heart disease.
When 70%-80% of the flowers fall, it is the critical period for preventing anthrax and mycotic diseases. The main medications are: phenacridazole, mancozeb, bromide zinc, carbendazim, thiophanate-methyl, etc.
The first time to control defoliation was in June, when the weather gradually turned hot, and pathogenic bacteria began to harm fruit trees. This period can be prevented by Bordeaux fluid. Every 20 days or so, mancozeb, tebuconazole, and carbendazim are alternately used. At the same time, we must also prevent red spider!
The weather in each place has different planting structures and there are differences in management plans. The specific situation we can discuss together!
The spring garden is usually in the first half of the bud, once in the red season, Xie spends about 80% of the spraying, 3 times in a row, spaced 7-10 days or so, and then began to bagging. Pre-pocket medication generally do not use EC, powder is generally not used. Both are high grade fungicides. The management after bagging is rather extensive, and it varies greatly depending on the region.
Apples usually use drugs 10-12 times a year. According to the situation, 11 drugs are normal. They are: dry branches (dormant period) in mid-late and late March, and Hualuhong period (mid-April). In early May-early June, mid-May, mid-May, 20 days after Xiehua, and late May, 30 days after Xiehua, about 2-3 days before bagging, 5-6 times after bagging. Once again fungicide.
