Control measures of Strawberry virus Disease

Strawberry virus disease is a difficult disease to control in strawberry growing period, which often brings great economic losses to farmers, so farmers should strengthen the prevention and control measures of this disease. Let's take a look at the symptoms, causes and prevention measures of strawberry virus disease together with Xiaobian.

1. Symptoms

Strawberry affected by a single virus disease, often symptoms are not obvious. Often after being infected by multiple viruses, it will show symptoms such as weak growth, degeneration, insufficient development of new leaves, dull leaves, chlorosis and yellowing, shrinkage and distortion, dwarfing plants, less fruit setting, low fruit yield, etc. The symptoms of strawberry virus disease are different, the common ones are strawberry mottle virus, strawberry light yellow edge virus, strawberry vein banding virus and strawberry wrinkle virus. The four symptoms are different, but they often lead to the decline of strawberry yield and quality.

2. Causes of occurrence

Strawberry virus disease occurs for many reasons, first of all is the seedling reason, planting seedlings with virus, has been in the seedlings continue to reproduce, until the environment is not suitable will soon come on, but also will connect soil, water infection of other plants. In addition, aphids, thrips, whiteflies, nematodes and other pests can also spread virus vectors, in the damage to strawberry plants, there may also be incorrect transmission, then the most important reason for the difficulty of controlling virus diseases, as long as there are pests, it can continue to spread. In addition, high temperature and drought environment is also easy to induce virus disease, high temperature and drought bad environment will cause poor plant growth, plant resistance decreased, easy to infect virus disease.

3. Prevention and control measures

In seed selection, disease-resistant varieties should be selected, non-toxic seedlings should be planted, sick seedlings should be strictly eliminated when caused, and introduction from seriously ill areas or seriously ill fields should not be carried out. Field inspection should be strengthened after planting. Once found, sick plants should be uprooted and burned in time. At the early stage of the disease, spraying is started. The commonly used pesticides are Zhibingling emulsion and Duxing moroxydine hydrochloride copper wettable powder. Control every 10-15 days for 2-3 consecutive times. In addition, it is necessary to control aphids from the seedling stage. It is best to use botanical pesticides to control aphids in greenhouses and damage them to pollinating bees.
