Prevention methods for grape crown gall disease
Today's topic is about grapes from the plant experience flower clinic, focusing on the prevention methods for grape crown gall disease. Let's learn about it together.
Grape crown gall disease is a bacterial disease that is spread through rainwater and irrigation water, etc. It invades through mechanical injuries or pruning cuts. After the bacteria enter, they stimulate the division of the epidermal cells, causing them to increase in size and form tumors. Once the host cells become tumor cells, they can continue to form tumors even in the absence of bacteria.
The bacteria can survive in the soil for more than a year, causing the seedlings to become diseased, growth to be hindered, and the plants to become stunted. The lateral and fibrous roots are reduced, and in severe cases, the leaves turn yellow and fall early; infected adult grapevines produce fewer fruits, smaller fruits, and in severe cases, no flowers or fruits, shortening the tree's lifespan and eventually leading to death.
Grape crown gall disease is one of the additional plant quarantine objects in the Inner Mongolia Autonomous Region. Currently, there are no effective control measures available domestically or internationally. If the disease occurs and is not treated in time, it can cause catastrophic damage.
Therefore, it is recommended:
1. The main way of long-distance transmission of bacteria in seedlings is one of the key ways to prevent bacterial infection in seedlings. It is essential to disinfect before planting. Special attention should be paid to the quarantine and epidemic monitoring of new grape nurseries to strengthen prevention and reduce the incidence of this disease.
2. For large-scale grape planting, it is best to propagate and grow grape seedlings oneself to reduce the chances of introducing dangerous diseases and pests from externally transferred seedlings. This can lower costs and improve the adaptability and disease resistance of the seedlings.
The above is a brief explanation of the prevention methods for grape crown gall disease, hoping to bring a little help to your life!
