Prevention and Mitigation of Herbicide Harm in Corn Field

With the increase in the proportion of herbicides applied, herbicides in corn fields in our province have become very common in recent years. Mild herbicides affect the normal growth of corn, while severely reduce the production. There are three types of corn herbicide poisoning: 1 Former use of perchlorosulfuron, imidazoyl niacin, metsulfuron-methyl, chlorsulfuron-type corn herbicide residues produced by the injury; 2 when the use of chemical herbicide such as sowing too shallow , Sustained low temperature, more rain, improper medication or excessive drug use is prone to injury; 3 For herbicides that control legume weeds after legumes and cash crops, they are close to the corn field and are easy to use when spraying. Corn caused drift hazards. Prevention and mitigation measures: Pay attention to the prevention of herbicide residues in the former crop; carefully select the correct use of 2,4-D, oxathione, and nicosulfuron to prevent the herbicides of the year. In the event of a phytotoxicity, corn may be sprayed with phytotoxicity relieving agents or plant growth regulators (brassica lactones), foliar fertilizers, etc. to alleviate the phytotoxicity in the early stage of the emergence of phytotoxicity symptoms, so that the damaged plants can resume growth as soon as possible. It is recommended to use 0.01% Trifluoperin 150ml or 0.1% Sophora 481 soluble powder per hectare for 120g or 0.003% AiZengMei 75ml mixed quality quick-acting foliar fertilizer to spray at the initial stage of symptoms of injury. Brassinolide can effectively regulate the physiological and biochemical functions of damaged plants, promote the restoration of normal growth of damaged plants as soon as possible, and high-quality foliar fertilizer can supplement nutritional plants.
