When the peanut is deficient in iron, the first part of the young leaves are chlorotic, while the lower old leaves and veins remain green. When the iron is severely deficient, the veins are chlorotic and yellow, and the upper new leaves are all white, and brown spots are necrotic. Dry and fall off. Compared with the chlorosis caused by nitrogen deficiency and zinc deficiency in peanuts, the characteristics of iron deficiency chlorosis in peanuts are prominently reflected in the absence of significant changes in leaf size and significant chlorosis. The yellowing and chlorosis caused by nitrogen deficiency often makes the leaves thin and small, and the plants are short; the zinc deficiency is easy to cause large clusters of leaves, and yellow and white leaf spots appear.
Peanut yellow leaf control method: Foliar sulphate solution can be used with the new high-fat film 600 times solution for foliar spray, spray once every 5-7 days, and can be sprayed 3-4 times continuously to enhance leaf adhesion. 0.1% detergent powder can be added to enhance the spraying effect and enhance the absorption function of the foliage.
