Pumpkin plants can sometimes experience a condition known as "melon," which occurs when the fruit stops growing and begins to wither, typically when it reaches the size of a fist. This phenomenon is often caused by environmental stress or improper care. To prevent this issue, timely application of pesticides is essential.
The main causes of pumpkin melon include excessively high temperatures, which can hinder fruit development and cause premature wilting. Over-fertilization, especially after harvest, can lead to excessive vine growth if pruning is not properly managed, resulting in an imbalance between vegetative growth and fruit production. Additionally, damage from pests and diseases can also contribute to this problem.
To avoid pumpkins turning into melons, several preventive measures should be taken. First, ensure the plants are resilient to heat and drought conditions. Second, implement proper cultivation practices based on the plant's growth stage. For overgrown vines, it's important to regulate fertilizer and water intake, while also focusing on pollination, pruning, and removing excess side shoots. Encourage the development of female flowers on the main vines and control the overall plant length. For weaker plants, apply additional fertilizers to support fruit growth. When dealing with pest or disease infestations, use targeted treatments. For example, insecticides like imidacloprid can effectively manage aphids, and other medications such as rehabilitation can also be used. It’s also crucial to monitor and control viral diseases that may be spread by aphids. For fungal issues like powdery mildew, products such as Fuxing, pink rust, or high-level pharmaceuticals can be applied for effective control.
In addition to these methods, maintaining good field hygiene, rotating crops, and regularly inspecting plants for early signs of problems will greatly improve the chances of healthy pumpkin development. With consistent care and appropriate interventions, pumpkin growers can significantly reduce the risk of melon formation and achieve better yields.
