Description
Technical field
The present invention relates to a kind of chemical herbicide composition, relate in particular to a kind of nicosulfuron 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, as surfactant etc., it is mixed with weed killer herbicide, preparation becomes aqueous suspension agent (english abbreviation is SC), make water-insoluble weed killer herbicide dispersion suspension in water, when reality is used, improve the weed killer herbicide effect to reach, perhaps two kinds of different weed killer herbicides are mixed according to certain ratio, kill the grass spectrum so that improve effect, the expansion of weed killer herbicide, as Chinese patent, application number: 02133350.5 disclosed technology.
At present, what commercially available effluent north Xuanhua farmingization Co., Ltd produced is 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, defoamer 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, to scheme to enlarge grass spectrum extremely, delaying the weeds resistance produces, makes things convenient for the peasant to use, but, the technology that this patent provides easily causes weed killer herbicide that the poisoning of crop is increased after the use.
Therefore, a kind of nicosulfuron herbicidal composition that contains agricultural chemicals synergist of developmental research will be the very expectation of people institute.
Summary of the invention
The purpose of this invention is to provide a kind of nicosulfuron herbicidal composition that contains agricultural chemicals synergist,, satisfy people's needs to overcome the above-mentioned defective that prior art exists.
The nicosulfuron herbicidal composition that contains agricultural chemicals synergist of the present invention, form by the component of following parts by volume:
