Symptoms and Control Methods of Melon Virus Disease
Today, we will introduce the symptoms and control methods of melon virus disease in green plant and flower introductions. Let's learn about it together.
Symptoms and Control Methods of Melon Virus Disease
flow.
When melon virus disease occurs, there are two types of symptoms: one is that the heart leaves show obvious veins, which then develop into dark green spots on the leaf surface, causing the leaves to become malformed. The other is a yellowing type, where the leaves initially show chlorotic spots, which later turn into mottled leaves, and the leaves also become yellow and thick. Once plants infected with melon virus disease are detected, it is necessary to spray with virus-specific agents, organic silicon, and zinc sulfate.
Symptoms of Melon Virus Disease
The symptoms of melon virus disease show two manifestations: one is that the heart leaves show obvious veins, which then develop into dark green spots on the leaf surface, causing the leaves to become malformed, and during dry periods, the diseased leaves will shrink.
The second is a yellowing type, where the leaves initially show chlorotic spots, which later turn into mottled leaves, and the leaves also become yellow and thick, with the leaf veins being more prominent and the leaf edges having a sawtooth shape.
Hazards of Melon Virus Disease
When melons are infected with virus disease, the leaves will produce systemic irregular necrosis, as well as chlorotic spots and spots. In severe cases, it will harm the plant, causing the plant to become dwarfed and the fruit to become malformed, affecting the quality.
Causes of Melon Virus Disease
Melon virus disease is a disease caused by the melon virus, which is transmitted by planthoppers, aphids, or thrips. This virus must寄生 inside melon cells and has a strong specificity. It will infect plants when the environment is suitable.
Medication for Melon Virus Disease
When plants infected with melon virus disease are first detected, it is necessary to spray with a virus-specific agent (40 grams), organic silicon, and 0.2% zinc sulfate. This is usually done on the 1st, 2nd, and 5th day, totaling three times. After the condition is under control, it switches to prevention.
Special Medication for Treating Melon Virus Disease
To treat melon virus disease, it is first necessary to control the vectors that transmit the virus. It is recommended to use fubenamine, pymetrozine, imidacloprid, thiamethoxam, etc., combined with chlorobromoisocyanuric acid, ningnanmycin, tetramycin, amino-oligosaccharides, foliar fertilizer zinc fertilizer, cytokinins, and abamectin for spraying.
Control Methods for Melon Virus Disease
1. You can plant a bit earlier, first soaking the seeds in warm water at 55℃ for 20 minutes, then transferring them to cold water to cool before germination and planting. It is also necessary to use mulch to promote rapid growth of seedlings and improve disease resistance.
2. When planting melons, avoid mixing them with seeds, watermelons, or zucchini to prevent cross-infection. Cultivate strong seedlings and plant at the appropriate time. During agricultural operations such as pruning, removing suckers, and pollination, be careful not to injure the leaves and vines to prevent contact infection.
