Disease control of Binchuanhong in the early stage

Yunnan Binchuan is an important production base of red grapes in China. The red grapes produced there are large, sweet and have high nutritional value. However, during the planting period of Binchuan red grapes, many diseases often occur. If they are not prevented and controlled in time, the quality of the red grapes will be greatly reduced, and the income of fruit farmers will also be affected. I will write down the specific methods of early disease prevention and control of Binchuan red grapes in a while, and friends in need can study them carefully.

Disease control of Binchuanhong in the early stage

1. Prevention and control of red grape white rot

In order to prevent the occurrence of white rot of red grapes, you can choose red grape varieties with strong disease resistance, or you can cut off the diseased branches and leaves in time during the planting period to clean up the source of the disease. In addition, in the early stage of white rot of red grapes, timely medication is used for treatment. Drugs such as carbendazim and methyl thiophanate have relatively good effects.

2. Red grape black pox

Black pox is also a common disease of red grapes. Prevention is the main approach to this disease. Drugs should be sprayed before the grapes germinate. Lime sulfur and ferrous sulfate are commonly used drugs to treat black pox. In addition to prevention, black pox can also be protected by drugs after the leaves unfold. Bordeaux mixture is one of the commonly used drugs. Spraying it can allow the fruit to color and grow normally.

3. Red grape downy mildew

Red grape downy mildew is a stubborn disease. It must be dealt with in time after it occurs, otherwise the vineyard will have this disease every year. The best way to deal with it is to burn or bury all the diseased leaves and fruits together in late autumn. In the year when it occurs, you can spray drugs for treatment in time. After the disease occurs, spray ziram, and spray once every two weeks, and spray three to five times in a row. The treatment effect is relatively good.
