First, the leaves are dry At the end of autumn grape harvesting, the main reason for leaf scorching is poor disease control, resulting in the hazards of “downy mildewâ€, “powdery diseaseâ€, “brown spotâ€, “black pox†and “anthraxâ€. The cure method: 1. Take comprehensive measures to effectively strengthen the prevention and control of “Downy mildewâ€, “powdery diseaseâ€, “brown spotâ€, “black spot disease†and “anthraxâ€. 2. Spray the "potassium dihydrogen phosphate" and "iron, zinc, magnesium, manganese, boron" and other trace element fertilizers. Second, leaf spot (or plaque) yellow (red, brown) In autumn, the leaves of the grape often appear obvious spots (or patches) yellow (red, brown). After investigation and analysis, it was mainly due to excessive fruiting, insufficient application and supply of organic fertilizer, potash fertilizer and trace element fertilizer, and lack of elements such as “potassium, iron, zinc, magnesium, manganese and boron†in the plant body. The cure method: 1, increase organic fertilizer, increase the amount of potassium fertilizer. 2, a small amount of root iron, zinc, magnesium, manganese, boron and other trace elements fertilizer. 3, spraying potassium dihydrogen phosphate and iron, zinc, magnesium, manganese, boron and other trace element fertilizers. When spraying, choose to spray sooner or later, pay attention to spray the back of the leaf, in order to enhance the absorption and utilization of leaf surface, improve fertilizer efficiency. Third, plant growth declined, even death In some individual grape plants, yellow and reddish leaves appear, and growth declines. The base of the stem begins to grow large and rot. Afterwards, the ants etc. enter the hazard. If the cure is not timely, the plants will die and cause seedling deficiency, which will affect the yield. The occurrence of heavy planting of new planted grapes and fruit trees. Mainly caused by white rot. The cure method: 1. Not to collect species in fields where white rot is severe. 2. Strengthen pastoral management and reduce damage to branches. 3. When spraying and preventing disease, pay attention to spraying old sticks or soil to improve control efficiency. 4, dig out the seriously ill strain, after disinfecting with quicklime, to make up the lack of batten.
