Background
Oxaziclomefone (Oxaziclomefone), chinese generic name: 7, removing barnyard grass; RYH-105; the oxaziclomefone has a molecular formula of C20H19Cl2NO2, belongs to organic heterocycles, is a systemic conduction type paddy field herbicide, is mainly absorbed by roots, stems and leaves of weeds, and leaves of the weeds lose green and stop growing after the weeds contact with the herbicide until the weeds die, and is taken orally at an acute time: >5000 mg/kg; acute percutaneous therapy: the weeding composition is more than 2000mg/kg, can prevent and kill barnyard grass, chickweed, moleplant seed, cyperus heterophyllus and other weeds, has good diffusivity and labor-saving weeding operation, and can be directly thrown from a bottle.
Clomazone, other chinese names: clomazone, chemical name: 2- (2-chlorobenzyl) -4, 4-dimethylisoxazole-3-ketone is an organic heterocyclic selective pre-emergence herbicide, is suitable for preventing and killing annual gramineous weeds and broadleaf weeds in crop fields such as soybean, peanut, corn and the like, has long lasting period, can achieve the whole growth period of crops by one-time application; the application time is flexible, the soil before the seedling seals the stem and leaf after the seedling, and the fertilizer has strong inhibiting effect on barnyard grass, green bristlegrass, large crabgrass, meadowrue grass, goosegrass herb, black nightshade and the like.
Pyrazosulfuron-ethyl (Clomazone) is a high-efficiency sulfonylurea selective paddy field herbicide, and the effective components can be quickly diffused in water, and are transferred into plant bodies after being absorbed by the roots of weeds, so that the synthesis of amino acid is hindered. Rapidly inhibit the growth of the stem and leaf parts of the weeds and the extension of the root parts of the weeds, then completely die, is safe to rice, has a wide insecticidal spectrum, and has good control effects on broadleaf weeds, cyperaceae weeds, barnyard grass and the like. The pesticide effect is not influenced by temperature, the pesticide effect is durable, the pesticide effect is applied once, and various weed hazards in the rice growth period can be controlled.
The herbicide mixture has the advantages of wide weeding spectrum, improvement of actual effect, delay of weed drug resistance, time saving and labor saving. Through pesticide formula screening, the actual control effect can be effectively improved, the dosage is reduced, the cost is reduced, and the generation of drug resistance of diseases, insects and weeds is delayed, so that the method is an important means for agricultural comprehensive treatment. The inventor of the invention has conducted intensive research on formulation screening of oxaziclomefone, clomazone and pyrazosulfuron-ethyl, and finds that mixing of oxaziclomefone, clomazone and pyrazosulfuron-ethyl has an obvious synergistic effect on annual weeds in a paddy field in a certain mixing proportion range, and further research has completed the invention.
