How to prevent getting rich leaf blight

It is found that the diseased leaves of the rich tree should be removed and destroyed in time. In the cultivation process of the rich tree, the conservation management should be strengthened, and watering and fertilization should be carried out in a timely manner. Two or three times of foliar fertilizer can be sprayed in each growing season, such as 0.5% potassium dihydrogen phosphate or double-effect micro-fertilizer 200 times liquid.

Before the seedlings are transported, the leaf surface is sprayed with a protective fungicide, such as 70% chlorothalonil 800 times solution, or 18% of the multi-bacteria copper milk powder 200 times solution, or 50% of the sterilized 600 times solution.

Seedlings should be planted in time after transport, strengthen fertilizer and water management, and prevent dehydration and de-fertilization. Spray 50% carbendazim 800 times solution, or 70% chlorothalonil 800 times solution, or 75% methyl thiophanate 1500 times solution every 10 to 15 days.
