Description
Technical field
The present invention relates to a kind of chemical herbicide composition, relate in particular to a kind of atrazine herbicidal composition.
Background technology
Weed killer herbicide is the widely used agricultural chemicals of modern agriculture, has been widely used in multiple kinds of crops productions such as paddy rice, wheat, rape, corn and vegetables.And the drug effect of killing weeds under the doses reaches maximum and be to estimate the main economic and technical norms of weed killer herbicide function to the infringement minimum of the crop protected.How to improve the effect of chemical herbicide, be always people the problem very paid close attention to.
At present, for atrazine herbicidal and nicosulfuron herbicidal, its conventional way is; Select proper supplementary material,, it is mixed with weed killer herbicide like surfactant etc.; Preparation becomes aqueous suspension agent (being abbreviated as SC), makes water-insoluble weed killer herbicide dispersion suspension in water, when reality is used, improves the weed killer herbicide effect to reach; Perhaps with two kinds of different weed killer herbicides according to certain mixed; Kill the grass spectrum so that improve effect, the expansion of weed killer herbicide, like Chinese patent, application number: 02133350.5 disclosed technology.
At present; The production of commercially available effluent north Xuanhua farmingization Co., Ltd be the weed killer herbicide of main active with the atrazine, be atrazine content and be 38% aqueous suspension agent (being abbreviated as SC), compatibilities such as atrazine and dispersant, thickener, anti-freezant, antifoaming agent and water are prepared into; Same; The nicosulfuron herbicidal of at present commercially available Japanese Ishihara Sangyo Kaisha, Ltd. is nicosulfuron content and is 4% aqueous suspension agent (being abbreviated as SC), and trade name be beautiful farming pleasure.
No matter be Chinese patent, application number: 02133350.5 disclosed technology, still commercially available is the weed killer herbicide of main active with the atrazine; And commercially available nicosulfuron herbicidal; All only considered the dispersiveness of active component, to improve result of use, therefore; And use the result to prove that its herbicidal effect is further improved.
Chinese patent 01127499.9 provides a kind of herbicide specially for corn field; Two kinds of pesticide processing of atrazine and nicosulfuron are become a kind of complex preparation; Kill the grass spectrum to scheme to enlarge, delay the weeds resistance and produce, make things convenient for the peasant to use, still; The technology that this patent provides is prone to cause weed killer herbicide that the poisoning of crop is increased after the use.
Therefore, a kind of atrazine herbicidal composition that contains agricultural chemicals synergist of developmental research will be the very expectation of people institute.
