With the rising temperatures in spring, squash virus disease enters its peak season. Greenhouses with poor management, insufficient fertilization, and inadequate irrigation are particularly vulnerable to this disease. Therefore, vegetable farmers should take proactive measures to prevent it.
First, understanding the symptoms is crucial. In the early stages, dark green spots appear on the leaves. As the disease progresses, the upper leaves become crinkled, and the plants show stunted growth. New leaves may display bright veins and mosaic patterns, with uneven coloration, smaller size, and yellowing margins. The leaves may also become curled or shriveled, and the fruits may fail to develop properly, resulting in deformed or no fruit at all.
Second, effective control methods are essential.
1. **Aphid control** is key, as they are major vectors for the virus. Farmers can use 2.5% deltamethrin, 10% imidacloprid wettable powder (diluted 1500 times), or 50% acephate WP (diluted 800–1000 times) alternately. Spraying should be done 3–4 times, with an interval of 7–10 days. In addition, installing insect nets in greenhouses can help prevent aphids from entering.
2. **Minimize contact transmission**. Viruses can spread through plant wounds caused by farming activities. Increasing row spacing and following a careful cultivation schedule—such as working on less infected plants first—can reduce damage. Early-maturing zucchini should avoid unnecessary pruning to prevent wound transmission.
3. **Improve fertilizer and water management**. Young squash plants are more susceptible to viral infections, so maintaining proper moisture levels is vital. During hot weather, watering frequency can be increased to lower soil temperature and prevent seedlings from aging prematurely. Shade nets can also be used when necessary.
4. **Chemical treatment** should be applied early. A 20% virazole wettable powder diluted 500 times or antitoxic agent No. 1 diluted 300 times can be sprayed every 7–10 days, repeating the process 3–4 times for best results.
By implementing these strategies, farmers can significantly reduce the risk of squash virus disease and protect their crops during the critical spring growing season.
