What is papaya mosaic virus disease? What are the control methods for papaya mosaic virus disease? Please provide guidanceDamage of papaya mosaic virus disease:
Papaya mosaic virus disease is a devastating disease that has commonly occurred in papaya production areas in recent years. Once the plant is planted, it will develop the disease, with mottled yellow flower spots appearing on the leaves. New leaves are densely packed and tightly bunched, quickly lose their green color and become hard and brittle, and are easily broken. Afterward, no new roots grow and no new leaves develop. The plant grows smaller and smaller and gradually withers and dies.
Infected plants of papaya mosaic virus disease cannot bloom or bear fruit, with low yield and poor quality.
Control methods for papaya mosaic virus disease:
1. After papaya seedlings are established and survive, drench the roots once with a mixed solution of 1000 times zinc sulfate and 600 times plant virus vaccine, about 1-1.5 kg per plant, to weaken the virus activity in the papaya plant body, which can significantly reduce the occurrence and damage of papaya mosaic virus disease.
2. During the growth and development of papaya plants, spray the leaves once every 15-20 days with a mixed solution of 600 times plant virus vaccine, 1500 times Shennongsu chelated fertilizer, and 1000 times zinc sulfate, or 800 times Bingdubike, 1000 times Zhuangfengyou, and 1000 times zinc sulfate mixed solution, evenly wetting all leaves, until water droplets begin to drip down. This can prevent and control the occurrence and damage of papaya mosaic virus disease.
3. Pay attention to controlling insects that transmit mosaic virus disease, such as aphids, scale insects, and whiteflies. During the growth and development of papaya, check the stems and leaves carefully. When the above pests are found causing damage, promptly spray 2-3 consecutive applications of 1000 times Yashijing aqueous solution, or 1500 times Jieshijing aqueous solution, or 1000 times Lesiben aqueous solution for control, spraying once every 7-10 days, evenly wetting all stems and leaves, until water droplets begin to drip down. This can kill the above pests and avoid the spread of mosaic virus disease.
