Crop deficiency symptoms

Symptoms of boron deficiency are generally manifested as inhibition of the apical growth, sprouting of lateral buds, clumping of branches and leaves, leaf shrinkage, curling, chlorosis, wilting and flower bud loss. When boron is deficient in corn, irregular white spots appear on the upper leaves, followed by white streaks, and the ear is deformed. When the peanuts lack boron, the fruit leaves shrink. Boron deficiency is more common in vegetable crops. For example, radish can cause brown heart rot. The center of the cucumber will appear woody, and rust spots will appear on the tomato fruit. When apples are deficient in boron, the fruit will have fruit shrinkage. Rapeseed, cotton, apple, Chinese cabbage, carrot are sensitive to boron, and rice and wheat are insensitive to boron.

Symptoms of molybdenum deficiency generally appear as yellow or orange spots in the leaves, and the leaf margin curls up like a cup, leaving the leaves deadly or underdeveloped. When broccoli is deficient in molybdenum, whiplash syndrome occurs. First, there are spots of water stains between veins, followed by necrosis. The lack of molybdenum radish when the performance of leaf degradation, leaf fissuring, leaf upturned. When the tomato was in 1 to 2 true leaves, the leaves turned yellow and curled, and then the new leaves showed spotted spots. The lacking green part arched up and the small leaves rolled up. Finally, the tip and leaf margins of the leaflets both shrank and died. Molybdenum-sensitive crops mainly include broccoli and radish, followed by tomato.

Symptoms of chlorine deficiency are generally characterized by wilting of plants and loss of green leaves. The lack of chlorine in tomatoes is mainly characterized by the wilting of the leaflets of the lower leaves, the growth is hindered, and then the wilting part is necrotic, and the lobule can not return to normal. When cotton lacks chlorine, the leaves are withered and the leaves are dark green. In severe cases, the leaf margin is dry and curled, and the incidence of young leaves is heavier than that of the old leaves. Due to the wide availability of chlorine, the chlorine in the fields and rainwater exceeds the annual demand of the crop. Therefore, the symptoms of lack of chlorine rarely occur in crops grown in Daejeon. (Zhang Qiaoyun)
