Some of the exposed cucumbers were susceptible to viral diseases in July, which were caused by three main viruses: Cucumber Mosaic Virus (CMV), Melon Mosaic Virus (MMV), and Tobacco Mosaic Virus (TMV). During the growth period of cucumber plants, mixed infections often occur. Typically, from the upper part of tender leaves, you can observe some flowers, while others show dark green, raised wrinkles, uneven leaf surfaces, or even fern-like leaves with lobes. These symptoms usually appear early, leading to stunted growth, wilting, or overall plant decline.
To prevent and control these viral diseases, a comprehensive approach is essential. This includes planting resistant varieties, improving cultivation practices, and implementing strict disease management strategies. First, it's crucial to grow strong seedlings and apply adequate phosphorus and potassium fertilizers to enhance the plant’s natural resistance. Second, maintaining field hygiene is important—always wash your hands with soap after touching infected plants or soil. Special attention should be given to controlling pests like aphids, especially during the seedling stage. If aphids are detected, insecticides such as imidacloprid, acetamiprid, or avermectin can be used effectively.
In the early stages of a viral infection, spraying 20% virus A wettable powder diluted at 500 times or 20% virus wettable powder at 600 times can help. Other substances, such as fluoroquinolones (like norfloxacin), have shown good inhibitory effects on the virus. Infected plants may still continue to grow, so using growth regulators that promote plant development can help maintain flowering and productivity even under disease stress.
If the infection becomes severe, a compound spray is recommended. The mixture includes 0.16% anti-sick Wei (virus K), 0.16% virus will (or other virus-inactivating agents), medical norfloxacin, virus Ling (1 tablet per liter of water), 0.16% zinc sulfate, and either natural cloudworm (Jinyunda-120) or naphthaleneacetic acid at 5 mg/l. The first application can be more concentrated, and then regular applications can follow after 1–2 treatments. For each sprayer containing 15 liters of water, the required amounts are: 25 mg of anti-disease agent, 25 grams of virus agent, 25 tablets of morpholine, 30 grams of zinc sulfate, and 1.5 grams of natural cloud alfalfa. This combination helps reduce symptoms and supports the recovery of infected plants.
