Spinach virus disease is a disease caused by virus infection. After the spinach is sick, the leaves shrink, the leaves are thin and deformed, the new leaves show a flower-like shape, the plants dwarf, and the old leaves fall off earlier.
The virus is overwintering on wintering spinach and vegetable weeds, and the seeds can also be poisonous. The virus is mainly spread and spread by locusts, and leaf friction can also be transmitted. The incidence of early sowing drought in the field is heavy, and the incidence of land near radish and cucumber is heavy.
Control methods:
1. Agricultural control. Use seeds harvested from disease-free plants. Field laying, hanging silver-gray plastic film strips to repel aphids, sticky tapeworm with yellow sticky board. Drought should be more watering, can reduce the incidence. Apply organic manure, increase phosphorus and potash fertilizers, and increase the disease resistance of spinach. Clean up the pastoral areas in time to eradicate weeds in the field and remove diseased plants in time. Do so at the right time to avoid sowing too soon. From the seedling stage, it is necessary to pay attention to controlling locusts in time and eradicate the transmission medium.
2. Chemical control. In the initial stage of disease, it is sprayed with 1.0% 1000 times solution of Lingzhi Ling emulsion or 0.5% antitoxic agent No. 1 water solution with 300 times liquid to prevent and cure. The addition of 920 or cytokinin to the drug enhances control.
