75 results about "Metsulfuron-methyl" patented technology

Metsulfuron-methyl is an organic compound classified as a sulfonylurea herbicide, which kills broadleaf weeds and some annual grasses. It is a systemic compound with foliar and soil activity, that inhibits cell division in shoots and roots. It has residual activity in soils, allowing it to be used infrequently but requiring up to 22 months before planting certain crops (sunflowers, flax, corn, or safflower). It has very low toxicity to mammals, birds, fish, and insects but is a moderate eye irritant.

A fertilizer used for killing pests and weeding and a preparation method thereof

The invention discloses a fertilizer used for killing pests and weeding. The fertilizer is prepared from following raw materials in parts by weight: 20-25 of weathered coal, 10-14 of river sand, 8-10 of bentonite, 10-13 of tobacco leaf residue and broken pieces, 20-23 of a nitrogen fertilizer, 14-18 of a phosphor fertilizer, 10-15 of a potassium fertilizer, 12-16 of potassium humate, 5-8 of calcium nitrate, 2-3 of citric acid, 1-2 of metsulfuron methyl, 6-9 of cane sugar, 11-15 of a soil conditioner and a proper amount of water. The fertilizer used for killing pests and weeding provides crops with energy and nutrients, increases the utilization rate of the fertilizer, allows the crop yield and quality to be improved, and has functions of killing pests and weeding, and therefore the fertilizer used for killing pests and weeding has many functions and high efficacy. The added metsulfuron methyl can effectively control growth of a plurality of weeds. The tobacco leaf residue and broken pieces contains a large quantity of vitamins and has a good pest killing effect. The potassium humate is an efficient organic potassium fertilizer, is capable of increasing the content of soil available potassium, reducing potassium loss and immobilization and increasing the adsorption rate and the utilization rate of the potassium by the crops, and has functions of conditioning the soil, promoting the crop growth, enhancing the anti-adversity ability of the crops, improving the crop quality, protecting the agroecological environment, and the like. In addition, the added soil conditioner can effectively improve the soil physical and chemical properties and soil nutrient conditions and can promote nutrient adsorption and water adsorption of the plants, and has positive influence on soil microorganisms.

Method for simultaneously measuring residue contents of five weedicides with different structures in soil

The invention discloses a method for simultaneously measuring the residue contents of five weedicides with different structures in soil, and belongs to the technical field of physicochemical detection of pesticide residues in the soil. Specifically, the residue contents of three types of five weedicides with different structures in the soil are directly measured by a high-performance liquid chromatographic (HPLC) instrument by combining dispersive solid-phase extraction (DSPE) with dispersive liquid-liquid microextraction (DLLME). According to the method, the defects and the condition limitations in the prior art are overcome, a method for pre-treating a soil sample and the detection conditions of the instrument are optimized, a DSPE-DLLME-HPLC method is built for simultaneously detecting three types of five weedicides (metsulfuron methyl, bensulfuron methyl, prometryn, atrazine and quinclorac) with different structures in the soil, the linear correlation coefficients are all more than 0.99, the detection limit is 1.5-3.1 ngg<-1>, the average recovery rate is 74.9-90.1%, the relative standard deviation (RSD) is 4.0-5.7%, both the accuracy and the precision meet the residue detection requirements, and the method has the characteristics of low organic solvent consumption, good purification and concentration effects, high sensitivity, simplicity for performing and the like.

Pesticide composition containing bispyribac sodium and metsulfuron methyl, and application thereof

The invention discloses a pesticide composition containing bispyribac sodium and metsulfuron methyl and application thereof. The pesticide composition comprises the following active components: bispyribac sodium and metsulfuron methyl which are in a mass ratio of 1-10: 0.1-1.5. The pesticide composition exerts an obvious synergistic effect on prevention and treatment of alternanther philoxeroides in the range of the above-mentioned ratio, so the application dosage of pesticide is reduced, pesticide application frequency is reduced, pesticide application cost is lowered down, and negative influence of the pesticide on the ecological environment is mitigated. Combination of the two active components enables spreading and regeneration capability of alternanther philoxeroides to be effectively controlled and defects and limitations in usage of a single active component to be compensated. The service life of the composition is prolonged, which is of great significance to comprehensive control of alternanther philoxeroides. Through combination of the two active components, drug effects are rapidly performed, action time of the composition is long, usage cost of the composition is low, and the composition can be used for preventing and treating alternanther philoxeroides.
