Common diseases of hanging melon and its control

Hanging melon may not be familiar with everyone, but hanging melon can not only be used for stir-frying vegetables, hanging melon seeds can also be processed into melon seeds for consumption. And the medicinal value of Diaogua is very high, which has been eaten for thousands of years in our country. The planting history is also very long, and now there are many people in the seed, but there will be many diseases and insect pests in the planting process, so what diseases and insect pests will appear? How to prevent and cure it? Let's take a look at it with me.

1. Vine blight

Disease characteristics: vine blight mainly harms the leaf melon and stem vine of hanging melon. After the leaf is infected, there will be a lot of yellow stripes on the leaf edge, which are distributed in the shape of "V". In the humidity environment, there will be many black spots on the strips. these black spots are the spores of the bacteria. The stem vine is similar to the leaf after the disease.

Prevention and cure method: when the stem vine of the hanging melon grows to a certain length, carry on the chemical prevention work to the stem vine once, and then carry on the prevention again according to the actual situation when growing from June to August, and the dosage depends on the growth situation. The medicine can be sprayed with Antaisheng wettable powder and so on.

2. Anthrax

Disease characteristics: anthracnose is the most troublesome disease in the hanging melon disease, which is likely to occur in the seedling stage and the final mature stage. It is a threat to all parts of the plant, causing great harm to melons, fruits and vines when the disease is rapid, and even directly leading to fruit decay and withering of stems. After the leaf is infected, there will be many spots on the leaf surface, these spots will gradually expand and extend, and then slowly merge to form huge patches, causing the leaves to wither and die and then fall.

Prevention and control methods: the incidence of anthrax is regular, and it is the most prone to anthrax in summer and autumn every year, so we should spray an appropriate amount of chemicals to prevent and cure anthrax before this time comes. After the onset of the disease, you can use carbendazim and other agents for continuous spraying, once a week, for at least three weeks.

3. Virus disease

Disease characteristics: the virus disease mainly harms the leaves of hanging melons, especially the old leaves, which begin to shrink and wrinkle at a speed visible to the naked eye. The leaves begin to bulge and become dry and brittle as if they had lost water. And the growth of branches will also be greatly affected, the branches are weak, showing the shape of hanging upside down, resulting in growth hindrance, so that the fruit setting rate is reduced, affecting the yield.

Prevention and control methods: the main way of transmission of virus diseases is aphids, so if we want to control virus diseases, we need to control the reproduction of aphids. When young buds emerge, chemical prevention should be used to strengthen orchard management, clear orchards regularly, remove diseased bodies and fallen leaves from orchards in time, reduce the existence of insect eggs in orchards, and control aphids. Spray such as oligosaccharides can also be added to the agents to control virus diseases. The number of times is the same as the prevention and treatment of anthrax.

The above three diseases are the diseases that often occur when planting hanging melons. If the diseases are not prevented in time, they will be very serious to the growth of the plant. But we also need to prevent pests while preventing diseases, because pests generally cause other diseases, so strictly speaking, the harm of pests is greater than diseases, strengthen management, find any abnormal situation must be dealt with in a timely manner.
