I. Sensitive Drugs and Diseases Symptoms Vegetable corns used in the use of dichlorvos, trichlorfon, phoxim, 2.4-D, etc., or excessive application may not produce the critical symptoms; such as 2.4-D applied or drifting. The leaves can be curled into onion leaves, the lower stems clustered together, and the aerial root volume is not in contact with the soil; over-application of phoxim can cause the leaves to become white or large in part, causing the leaves to dry and freeze-like. The use of pesticides or herbicides, if the concentration exceeds a certain level, can result in abnormally colored leaf classes such as leukoplakia or brown spots, curling or thickening of young shoots and roots, suppression of plant growth, shortening of temporal lobe or exposure of grains and grains; Excessive use of pesticides or excessive application of pesticides will always germinate or die after emergence, residual dwarfing, yellowing or dead leaves. Excessive application of chemical fertilizers, such as soluble nitrogen, potassium and other fertilizers close to the seed, will inhibit the germination of seeds or cause death after seedling emergence; phosphorus phosphorus and other organophosphorus pesticides produce discoloration and other phytotoxicity mechanism is the strong hydrophobic organic phosphorus Pesticides are adsorbed by green leaf tissue or surrounding tissues, resulting in flocculation of chloroplast function, which hinders the electronic conduction reaction, that is, the Hill reaction, inhibits photosynthesis, discoloration occurs, the more serious the injury, the reduction of carbohydrate content in the body, the total nitrogen content Relative increase. Due to the different conditions of corn varieties, development stages, and environmental factors. Different degrees of injury will cause the leaves to die, discoloration, deformity and so on. Second, prevention and control methods: 1, using formula fertilization technology, timely and appropriate application, should not be excessive. 2. When using herbicides, strictly select varieties and master dosages to avoid over-concentration, and it is not advisable to spray directly at the bell mouth. 3. Do not use sensitive insecticides such as trichlorfon and dichlorvos in the corn field, and strictly control the dosage when using phoxim to control underground pests. 4, found that high concentrations should be watered immediately. 5, after the occurrence of phytotoxicity, we must strengthen management. 6. If necessary, spray Fengbao I type active liquid fertilizer 400-500 times.
