Prevention of squash virus disease in time

Zucchini virus disease is mainly transmitted by ticks. With the increase of temperature, the incidence of summer squash virus disease has reached a peak period. In particular, lands with extensive management and unfavorable supply of fertilizers and water are prone to onset. Virus infections cause large losses, and production can be reduced by more than 1/2 in severe cases. Therefore, timely prevention of squash virus disease.

Symptoms Symptoms In the initial stage of disease, dark green spots appear on the leaves, and the symptoms gradually worsen. The upper leaves of the diseased plants are chicken-like, and the plants are dwarf. The new leaves show bright veins and mosaics, the leaves are unevenly colored, the leaves become smaller, and the nicks are missing. Deep, leaf margin yellow, shrinkage, diseased melon, no melon or melon malformation.

Prevention and control methods eliminate aphids: Aphids are an important vector for transmission of viral diseases. The occurrence and severity of viral diseases are closely related to the occurrence of aphids. Therefore, prevention and control of aphids is one of the key measures to prevent viral diseases. Can be used 2.5% deltamethrin or 10% imidacloprid wettable powder 1500 times, or 50% anti-inferiority WP 800 to 1000 times, or 10% cypermethrin EC 2500 times alternating spray, even spray 3 to 4 times , spray once every 7~10 days, where conditions can also install insect nets to prevent locusts from entering the shed. Reducing exposure to virus transmission: Viral diseases can be transmitted through plant wounds. Therefore, the row spacing should be increased in order to minimize the wounds caused by agricultural operations. Farming operations should follow the principle of "spontaneous strains after the disease." For early maturation of zucchini, it is not necessary to burp and avoid causing wound transmission. Strengthen the management of fertilizers and waters: The premature death of seedlings of zucchini is highly susceptible to viral diseases. In cultivation, fertilizer and water management must be strengthened to prevent premature aging due to dehydration due to lack of water. Chemical control: At the beginning of the disease, 20% virus A wettable powder 500 times solution, or antitoxic agent No. 1 300 times solution, or potassium permanganate 1000 times solution, sprayed once every 7~10 days, even spray 3 ~4 times, the above liquid can be used interchangeably.
