Grape anthracnose is a common disease during grape cultivation.

So what are the symptoms of grape anthracnose? How should we prevent and control grape anthracnose in daily life?

symptom

After the onset of grape anthracnose, brown circular spots the size of a needle tip will appear on the grape fruits. As the disease worsens, the spots will become larger and larger, and finally form obvious depressions. When the weather is humid, red sticky substances will appear around the spots.

Prevention and treatment methods

1. Prevention and control method 1

If you want to prevent the occurrence of grape anthracnose, you can remove all the diseased branches and diseased and dead fruits when pruning grapes in winter, collect them, destroy them in a centralized manner or bury them deep underground. This can reduce the number of pathogens and prevent the occurrence of grape anthracnose.

2. Prevention and control method 2

Bagging is also one of the main methods to prevent grape anthracnose, especially in areas where the disease is serious. Grape berries can be bagged in time when they grow to the size of soybeans in mid-June. This can reduce the damage of the pathogen to the grape fruit and thus reduce the occurrence of grape anthracnose.

3. Prevention and control method three

Drug treatment is also an important method for preventing and controlling grape anthracnose. You can spray sodium pentachlorophenol solution during the growing period of grapes, and spray again when spores appear in the garden. Then use the medicine once every fifteen days, and use it three times in a row.
