Abstract
The invention relates to a nicosulfuron weedicide composite which contains effective adjuvant for farm insecticides and is prepared by the components by volume proportion of 100 portions of nicosulfuron suspending agent diluents and 0.05-0.5 portion of effective adjuvant, wherein, the nicosulfuron suspending agent diluents are formed by diluting nicosulfuron weedicide the mass content of which is 4% in water into 300-1500 times of volume; the effective adjuvant contains the following components by weight percentage: 10-20% of methyl hexadecanoate, 5-10% of methyl stearate, 20-40% of 9-cis-octadecenoic acid methyl ester, 20-40% of 9-cis, 12-cis-octadecadienoic acid methyl ester, 10-20% of 9-cis-11-trans-13-trans-ecoric acid methyl ester, 10-20% of benzene ethylphenol polyoxyethylene ether and 1-5% of calcium alkylbenzene sulfonate. The composite has the advantages of available raw materials, no environmental pollution, convenient preparation and easy application, can obviously enhance the efficacy of the nicosulfuron weedicide, and has great application value.
Description
technical field [0001] The invention relates to a chemical herbicide composition, in particular to a nicosulfuron herbicide composition. Background technique [0002] Herbicides are widely used pesticides in modern agriculture, and have been widely used in the production of various crops such as rice, wheat, rape, corn and vegetables. The main economic and technical indicators for evaluating the function of herbicides are to maximize the efficacy of killing weeds at a certain dose and to minimize the damage to the protected crops. How to improve the efficacy of chemical herbicides has always been a subject of great concern. [0003] At present, for atrazine herbicide and nicosulfuron herbicide, its conventional practice is to select suitable auxiliary materials, such as surfactants, etc., mix it with herbicide, and prepare it into water suspension (English abbreviation is SC ), to disperse and suspend the water-insoluble herbicide in water to improve the efficacy of the he...
