China has the highest garlic planting area and garlic production in the world. Chinese people like to eat garlic, but garlic farmers often have various diseases in the process of garlic planting and growth, such as yellowing of garlic leaves. As one big garlic suppler, I often see this disease when we go to see our garlic farming base.
The causes of yellowing of garlic leaves can be divided into physiological and pathological reasons.
Physiology: lack of nitrogen, potassium, calcium and magnesium will lead to yellowing of garlic leaves, or management reasons such as fertilizer damage and drug damage, and environmental factors such as temperature, humidity and soil will also lead to yellowing of garlic leaves. Pathological: blight, leaf blight and bacterial soft rot may cause yellowing of garlic leaves.
