The main criteria for herbicide phytotoxicity are: weak yellow seedlings, slow growth, black root dead seedlings, green and necrotic stems and leaves, malformations, reduced flower and fruit numbers and no heading.
Second, the herbicide damage remedies
1. Water spray detoxification: When herbicides are applied in excess, spray the affected crops 3 or 5 times as early as possible. For herbicides that are easily decomposed with alkaline substances, spray with 0.2% lime or 0.2% sodium carbonate solution. Wash to reduce the residual amount of foliar pesticides.
2. Drainage and Irrigation: For the application of herbicides such as 2 A 4 Cl 2 and 2,4-D butyl esters, it is possible to use a large amount of water first, then to drain the water, then to fill in the fresh water, and to combine the top-dressing quick effect. Nitrogen fertilizer promotes the recovery of physiological functions in affected areas as soon as possible.
3. Strengthen field management: (1) Combine watering, increase organic fertilizers and quick-acting fertilizers, promote root development and regeneration, restore the physiological functions of the affected crops, and mitigate drug damage; strengthen the cultivating loose soil, increase the permeability of the soil, and increase the ground temperature; Enhances the ability of roots to absorb nutrients and moisture, so that the plants can restore growth and development as soon as possible and reduce the damage caused by phytotoxicity. (2) Spray foliar fertilizer: After the occurrence of the injury, spray the foliar fertilizer in time, usually 5 to 7 days to spray 1, and spray 2 to 3 times, 1%~2% urea solution can be used, 0.3% Potassium dihydrogen phosphate solution, Tianda 211, vigor, Tianfengsu, or Huimanfeng 800-1000 times liquid spray. (3) Spraying plant growth regulators: crops are subject to phytotoxicity caused by hormonal herbicides such as 2,4-D butyl ester, 2 A 4 chlorinated, paracetamol, and cimarone, etc. When crop residues of herbicides are damaged by crops, plant growth regulators such as alizarin lactone and sodium nitroprusside may be sprayed at the seedling stage to stimulate the growth of the damaged plants.
4. Application herbicide antidote: Naian is a herbicide side effect prevention and control agent has been widely used. Nai 80 grams per mu can be used in combination with herbicides for soil closure. After misuse of herbicides, spraying 80 to 100 grams of Nai'an per acre can relieve herbicides and reduce the inhibitory period of herbicides by more than 10 days. In the early stage of the emergence of herbicides in crops, 80 to 100 grams of Naian per acre was used to spray stems and leaves. Http://Content/e353cd3c-3408-4f13-8a89-59203a08ffb3?cType=2
