Cucumber flow plastic is Sclerotinia?
In winter and spring, the humidity in the shed during the low temperature season is relatively high. In addition, there are hazy weather from time to time. Many cucumber sheds do not vent in time, causing sclerotial sclerotia to spread in the shed. Many vegetable farmers believe that the phenomenon of plastic flow on melon strips or stems is a sclerotiorum disease.
Actually, this is a wrong understanding because it may be caused by other pathogens. The net sclerotia will not only prevent the disease, but will also cause plant damage. Sclerotium is a powerful antibacterial agent. If it is used improperly, the main symptoms are as follows: Cucumber shows malformed melons (mostly sharp-edged melons), and there are yellow spots between the leaves or veins.
To identify Sclerotinia, from the sclerotia, the sclerotia will make cucumber plants grow white hairy hyphae, or in the early occurrence of gray mold, will develop in the disease later in the disease part of the brown rat urine Substances, which are typical symptoms of Sclerotinia, are usually produced at the base of decayed stems, so the melon strips or stem vinegars that are common in production are not Sclerotinia.
So how about melons or stems? In fact, there are many kinds of diseases that can cause the flow of glue in cucumbers. Fusarium wilt, anthracnose, blight, and scab can all cause melon strips or stems to swell. The symptoms of these diseases are similar. Differentiation: In general, Fusarium wilt is just on the vine upper stream; real scabs occur less often, and when scabs occur, dark green spots appear on the melons, and the disease is sore; anthrax; Diseases and sprains can cause gums to appear on melons or vines. The symptoms of leaf blight on the leaves are circular or "V"-shaped brownish spots inward from the leaf margins, and are easily broken in later stages. Black spots appear on the lesions. In addition, if the melon strip is subject to injury, it will also cause fluid leakage.
This is a self-regulating method of cucumber.
What happens to the phenomenon of flow of cucumber? Can use the following methods: First, reduce greenhouse moisture. When watering, it is necessary to dilute with water and choose sunny watering at noon. In cloudy days, aerosols can be used to prevent various diseases and increase air humidity. Second, it can be used to prevent ammonia and other copper agents. Since the melon strips may also be accompanied by cucumber rot or gray mold, they should be supplemented with drugs such as Botryphine or Sulfamethoxazole to prevent the melon from getting infected again. To prevent the occurrence of this disease, the key is to control the humidity of the air. Especially in the dark, the cucumbers in the protected areas must pay attention to strengthening the ventilation on the basis of maintaining the temperature in the shed.
