[0006] Chinese patent 01127499.9 provides a special herbicide for corn fields. Atrazine and nicosulfuron are processed into a compound preparation in order to expand the herbicidal spectrum, delay the emergence of weed resistance, and facilitate farmers to use , however, the technology provided by this patent will easily lead to increased phytotoxicity of herbicides on crops after use

Abstract
The invention discloses an atrazine weedicide composite containing effective adjuvant for farm insecticides, and the composite is formed by the components by volume proportion of 100 portions of atrazine aqueous suspending agent diluents and 0.05-0.5 portion of effective adjuvant, wherein, the atrazine aqueous suspending agent diluents are formed by diluting atrazine weedicide of 38% weight content in water into 200-300 times of volume; the effective adjuvant is composed of the following components by weight percentage: 10-20% of methyl hexadecanoate, 5-10% of methyl stearate, 20-40% of 9-cis-methyl-6-octadecenoate, 20-40% of 9-cis, 12-cis-octadecadienoic acid methyl ester, 10-20%of 9-cis-11-trans-13-trans-octadecadienoic 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 atrazine weedicide, and has great application value.
Description
technical field [0001] The invention relates to a chemical herbicide composition, in particular to an atrazine 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 method is to select suitable adjuvant, such as surfactant, etc., mix it with herbicide, and prepare it into water suspension (abbreviated as SC) , to disperse and suspend water-insoluble herbicides in water to improve the efficacy of herbicides in actual use, or mix tw...
