Cherry brown rot is a more harmful disease, which can damage flowers, leaves, fruits, branches and other parts, among which the fruit is the most seriously damaged. The following methods can be used to control pesticide fungicides :
1. Eliminate the source of overwintering bacteria, completely remove the diseased fruit and diseased branches, and burn them intensively. Combine the orchard with the tillage and bury the stiff fruit below 10cm.
2. Spray 3-5 degrees stone sulphur mixture before germination.
3. In the initial flowering period, spray 50% speed Keling 1000 times after spraying, or 30% nail frosting 1500-2000 times, 70% Jiato 800-1000 times, 50% more mildew 1000 times. 40% Longli (Scharlot, pyrimethanil) 800-1000 times. After that, spray again twice every 10 days.
4. Spray 50% myristicin 1000 times solution or 50% phlegm 1000 times in the first 30 days before maturity. 24% cyanobenzophenone (should be) 2500-3000 times alternately with Dasheng.
Once the brown rot of cherry occurs, it must be prevented in time. The fruit damage will occur from young fruit to maturity. Therefore, timely selection of fungicides is the key.
