What causes loofah vine rot? You need to learn these preventive measures

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

I. Causes of loofah vine rot

In winter, the temperature itself is relatively low and light is insufficient, so the greenhouse temperature becomes too low and humidity too high. If the ventilation volume is too small, bacterial diseases will 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, causing 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 the wounds can heal as quickly as possible, reducing the probability of bacterial disease transmission and the possibility of vine rot occurring.

2. In addition, when pruning and picking the gourds, promptly apply agents such as copper hydroxide and copper quinoline to the wounds; this can block bacteria from invading through the wounds and prevent disease. Under good ventilation conditions, pesticides can be sprayed in time for control. When the disease is severe and the greenhouse ventilation volume is small, fumigation can be used for control, so as to reduce greenhouse humidity and improve the control effect.

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

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