Symptoms of Grape Yellow Leaf Disease
Grapes grown in highly alkaline soil are prone to yellow leaf disease, causing the leaves to turn yellow, followed by a transition to yellow-green or yellow-white, with the vines ceasing growth and shedding leaves.
Grape yellow leaf disease is caused by iron deficiency, and in severe cases, the leaf surface turns pale yellow or yellow-white, leading to reduced fruit setting, lower quality, and low yield in the later stage.
Medication for Grape Yellow Leaf Disease
In the early stage of grape yellow leaf disease, you can spray citric acid solution or a mixture of ferrous sulfate solution once a week. Avoiding direct sunlight will enhance the effectiveness.
Grape yellow leaf disease can be prevented by spraying a moderate amount of benomyl or zineb to prevent pests, and when yellow leaf disease appears, spray ferrous sulfate solution for treatment.
Prevention and Control Methods for Grape Yellow Leaf Disease
The treatment method for yellow leaf disease involves spraying benomyl during the growing period of grape yellow leaf disease. If yellow leaves appear, spray ferrous sulfate solution promptly to improve the soil's acidity and alkalinity.
Grape yellow leaf disease should be remedied by using foliar fertilizers, such as spraying yellow fulvate or amino acid complex fertilizer plus micro-fertilizer potassium dihydrogen phosphate, for 3-5 consecutive times, followed by soil acidification.
