With the improvement of people's understanding of bitter vegetables, bitter vegetables have become one of the popular foods with certain health care functions. Although the disease resistance of bitter gourd is very strong, the diseases of bitter gourd, such as chilling injury, anthracnose, virus disease, powdery mildew, brown spot and so on. Is the main disease that harms bitter gourd. How to effectively prevent it?

It belongs to the female-dominated disease in the hospital, also known as fungal disease of cucumber pathogen. The spores of mature oocytes are yellowish brown or yellowish. Infectable fruits, seedlings, pearls and infected fruits lose their commercial value. Generally, pedicels are infected first, and fruits appear first. The head is concave, nearly round, dark green and scaly. With the spread of the disease, rare fungi appeared on the surface of the fruit, and soft and rotten wrinkles appeared on the affected area. In actual production, we found that most seriously ill plots have poor ventilation, high field humidity and poor soil permeability. If it rains heavily in Georgia, it is easy to induce the epidemic of infectious diseases. There are many ways for infectious diseases to infect plants. For example, the whole plant of bitter gourd is damaged, stomata, micro-damage caused by agricultural labor and so on.

Infectious diseases of bitter gourd are generally mainly prevented. If bitter gourd itself has no hope of cure after illness, it should be removed as soon as possible. After dinner, bitter gourd will not be watered except drinking water before it reaches its full mother, in case the humidity is too high, which will induce bitter gourd disease. After the delayed seedlings reach the initial flowering stage, water them according to the drought situation of the land. If planted outdoors, stop watering when the weather forecast is rainy. Too much rain after watering and too high humidity in the field will induce female insects to get sick. The day before watering bitter gourd, spray fungicides everywhere. 2000 times of liquid 30% AKUSESTER suspension (30%) can be used. Or choose 800-fold solution of 64% virus vaccine and 800-fold solution of chlorothalonil (800-fold solution) and spray it carefully to 2 1 16 every day, which can prevent the female host from getting sick.

After the disease of bitter gourd vine, it is necessary to thoroughly remove the disease, pull out the seedlings, and remove the remaining leaves and fruits together for harmless treatment. In fields with serious diseases, stubble should be planted in turn, preferably with gramineous plants in turn, for at least 3 to 5 years. Some fields were originally free of infectious diseases, so melon seeds were introduced. The germs in the seeds were not completely killed and brought to the ground to cause diseases. Therefore, when planting bitter gourd, thoroughly disinfect the seeds to kill pathogens. Generally, bitter gourd seeds are mixed in warm water of about 60 degrees 15 minutes, and the water temperature drops to 30 degrees at room temperature. Some clothes are packed with rich rice, which has better sterilization effect.
