Analysis of the Causes of Luffa Vine Rot and Preventive Measures

Luffa is a crop that thrives in high temperatures, with an optimal daytime growing temperature between 28-32 degrees, so it is mostly planted in summer and autumn. It also prefers moist soil and a relatively dry air environment. During winter greenhouse cultivation, luffa vine rot is often encountered. What causes it? Let's find out together.

I. Causes of Luffa Vine Rot

In winter, the temperature itself is relatively low and light is insufficient, which leads to excessively low greenhouse temperatures and high humidity. If the ventilation rate is too small, it will cause bacterial diseases to break out in large numbers. When picking the gourds or carrying out farming operations, the wounds on the plants are difficult to heal, and pathogens quickly invade, leading to vine rot.

II. Preventive Measures

1. When carrying out farming operations such as picking the gourds, be sure to do so when ventilation conditions are good and the air is relatively dry, so that the wounds heal as quickly as possible, reducing the chance of bacterial disease spread and the possibility of vine rot occurring.

2. In addition, when pruning and picking the gourds, promptly apply agents such as Keshade and copper quinoline to the wounds. This can prevent bacteria from invading through the wounds and prevent disease occurrence. Under well-ventilated conditions, pesticides can be sprayed in time for control. When the disease is severe and the greenhouse ventilation rate is small, smoke fumigation can be used for control, to reduce greenhouse humidity and improve the control effect.

3. When carrying out farming operations, it is not advisable to do so in rainy weather or when ventilation is poor and humidity is high. At such times, absolutely do not remove leaves or pinch off branches, in order to control the spread of pathogens and reduce the possibility of vine rot occurring.

4. One more point: when watering, appropriately control the water. When watering, it is best to choose drip irrigation or the under-film watering method, to avoid excessive humidity and severe pest and disease occurrence. Rice husks or straw can be laid down to achieve the purpose of raising ground temperature and reducing greenhouse humidity, thereby reducing the occurrence of vine rot.
