When selecting herbicides, it should be easy to decompose in soil or plant body, with short duration and low residue. The following pesticides are recommended for you in China's pesticide network , which can be used as needed.
Benzorone has a short duration of action in the soil and has no effect on the crops, which is highly safe for wheat crops. It is suitable for the control of grassy weeds such as wild oats before the 5-leaf stage, and can be used to treat broad-leaved weeds in wheat fields with 2 to 4 chlorine. When used, the surfactant ammonium sulfate, vegetable oil and mineral oil can be used to significantly improve the efficacy.
The catching period in the soil is very short and has no effect on the crop. Suitable for use on dicotyledonous crops and vegetables such as soybeans, beets, canola, flax, and cotton.
The three herbicides, pentachlorophenol, dinitrophenol and dinose, have a relatively short duration of action in the soil, generally 2 to 4 weeks. However, after the animal is absorbed, it is difficult to be metabolized and remains in the body, so it is highly toxic to animals and should not be used in rice fields for raising crabs and raising fish.
According to the pesticide network , the two herbicides, acetochlor and butachlor, have a short duration of action in the soil, generally 1 to 3 months. Most varieties have low volatility and are easily degraded in plants. Due to long-term use, attention should be paid to changing the variety. Glyphosate is highly efficient, broad-spectrum, low-toxic, easy to decompose, and safe for the environment. It is a herbicide herbicide suitable for use in orchards, roadsides and non-cultivated land.
The three herbicides of trichlorobenzoic acid, legumin and herbicide have a shelf life of 6 to 12 weeks in the soil. Among them, trichlorobenzoic acid and herbicide are suitable for crops such as wheat and corn, and control perennial deep-rooted broad-leaved weeds, such as Tianxuanhua, Tianqi, and Chicory. Bean Kewei is suitable for crops such as soybean, peanut, corn, sunflower, carrot, tomato, pepper, sweet potato, etc. Pre-emergence soil treatment is used to control annual monocotyledonous weeds.
Dinitroanilines include trifluralin, aminoethionine and the like. Easy to solve. Applicable to cotton and legumes, cruciferous crops, cockroaches, crabgrass, goosegrass, foxtail, and maiden.
2 A 4 chlorine in the soil for 2 to 8 weeks. The lower the temperature, the more dry the soil and the longer the duration of the effect. Applicable to wheat, rice, corn and other cereal crops, stem and leaf treatment to control annual or perennial broadleaf weeds.
Sin cure rapidly degraded in the soil, pesticide Vinca short. Applicable to soybean, cotton, tobacco, peanut, rice and other crops, pre-emergence soil treatment to control annual grass weeds and broadleaf weeds.
