What is the best medicine for the prevention and treatment of grape yellow leaf disease
A comprehensive explanation of the best medicine for the prevention and treatment of grape yellow leaf disease in the field of green plants and flowers, let's understand together next.
What is the best medicine for the prevention and treatment of grape yellow leaf disease
If grape yellow leaf disease is caused by iron deficiency, it is generally treated with 100ml of ferrous sulfate solution. Unsuitable soil can also cause grape yellow leaf disease, usually treated by adjusting soil acidity, and it is necessary to loosen the soil frequently to reduce soil salinity and alkalinity. More sunlight should also be provided to prevent the occurrence of grape yellow leaf disease.
What is grape yellow leaf disease
Grape yellow leaf disease is a common disease in grapes. In the early stage, the young leaves turn yellow, and in the later stage, most of the leaves become yellowed, affecting the growth of the entire plant, and the berries will start to fall off. Timely spraying of medicine is required upon detection.
Treatment for grape yellow leaf disease
1. Unsuitable soil: In this case, the method of adjusting soil acidity is generally used to prevent and treat, reducing the salinity and alkalinity of the soil and loosening the soil frequently.
2. Insufficient sunlight: As long as excessive branches and leaves are pruned on time to avoid being too dense, maintaining ventilation and light penetration, and fully absorbing sunlight is sufficient.
3. Lack of iron elements: Iron deficiency-induced yellow leaf disease can be treated by the method of burying bottles to absorb iron under the ground, placing 100ml of ferrous sulfate solution in the bottle and placing it in the tree pan.
Prevention of grape yellow leaf disease
1. Try to supplement the nutrient elements needed by grape plants, such as organic and inorganic foliar fertilizers, spray 3-5 times with a solution of 300-500 times fulvic acid salt or amino acid compound fertilizer mixed with 300-500 times of micro-fertilizer potassium dihydrogen phosphate, which can effectively regulate physiological functions.
2. In cases of iron deficiency, it is necessary to use the buried bottle treatment method more often, which has a very good correction effect. Place 100ml of ferrous sulfate solution in the bottle, seal the bottle opening, and insert fine roots into the bottle opening, then bury it in the soil.
3. Excessive soil salinity and alkalinity can lead to an imbalance in the physiological state of grapes, hindering the supply of nutrients. In this case, the method of adjusting soil acidity should be used for prevention and treatment, which can reduce the local pH of the soil to convert insoluble iron elements into effective ones.
