The disease manifests itself in the form of a plaque resembling flour in appearance. The spots begin to gradually dry out and turn yellow. This means that the plant is sick. Powdery mildew likes to "attack" young plants in gloomy, wet weather.
Prevention: it is required to observe crop rotation, remove old organic matter in time, disinfect the ground, maintain a temperature of twenty-three degrees Celsius in the greenhouse, and cover the vines with a film. When the first signs of the disease appear, it is recommended to spray the plants with a fungicide.

Prevention: disinfection of seeds and seedlings during planting is necessary, annual digging of the earth and disinfection with copper sulfate or potassium permanganate, watering with warm water. It is recommended to remove and burn infected plants.
