Control measures of blueberry mosaic disease

Mosaic disease is a common disease in blueberry production. When the disease occurs, the yield can be reduced by about 15%. It will also affect the fruit varieties and do great harm. The following editor brings you the symptoms and prevention methods of blueberry mosaic disease. Let's take a look.

1. Occurrence of symptoms

Mosaic disease is a disease that harms mosaic leaves. The disease is caused by pink, yellow or yellowish green spots and red stripes on one or more branches, spots and annular wilt, and purple spots. After the fruit, it will also infect the fruit, resulting in disease spots on the fruit surface, causing the fruit to grow slowly or form a stiff fruit, which is very easy to fall off, and the fruit quality will be very poor after ripening, and the yield will be reduced by about 15%. If it is not prevented and treated in time, the yield reduction may be more serious.

2. The route of transmission

The disease does not occur every year and may be related to light intensity and field permeability. its main route of transmission is through centimeter aphids and virus-carrying seedlings and soil. The virus lurks in the seedlings, and when the plant grows to a certain extent, the virus begins to break out and spreads the disease through soil and water, causing plants in the region to be infected with the disease, especially in the outbreak period of aphids. After the aphids ingest the juice of the virus-carrying plants, the virus will latent in the body, and the virus will spread through it when sucking other plants.

3. prevention and control measures

In order to effectively control the occurrence of the disease, it is necessary to deal with the land before planting, clean up the diseased plants and weeds in time, and do a good job of disinfection after turning the soil and preparing the soil. When planting, the seedlings with strong growth, strong disease resistance and no disease should be selected. after planting, we should strengthen field management, increase fertilizer application, improve disease resistance, properly prune, maintain good ventilation and light transmittance in the field, and reduce the incidence of disease. Control is the effective use of insecticides to spray aphids, control the number of aphids, cut off the route of transmission, for light diseased plants can be pruned, spray chemicals, while the more serious plants can be pulled out of the garden, and do a good job of disinfection.
