Abstract
The invention relates to the technical field of pesticide production and discloses a formula of a weeding composition. The composition contains two active ingredients, namely trifludimoxazin and pyroxasulfone. The composition is obtained by mixing auxiliaries including thickener, dispersant, antifreezing agent and defoamer with water and then conducing high-speed shearing, wet sanding and uniform filtering to obtain a suspending agent. The weight ratio of the active ingredients trifludimoxazin and pyroxasulfone is 1:10-20. The weight percentage of the two active ingredients in the composition is 16-65%. By mixing the two active ingredients trifludimoxazin and pyroxasulfone, the defects of a single ingredient are overcome, a remarkable synergistic effect is realized, safety performance is high, and the composition is an ideal weeding composition.
Description
Technical field
The invention belongs to pesticide field, relate to a kind of Herbicidal combinations with improvement, particularly relate to a kind of Herbicidal combinations containing trifluoro grass piperazine and sulfone pyrrole grass azoles.
Background technology
At present nearly 30,000 kinds of weeds all over the world, wherein about 1800 kinds of every annual meetings bring the total yield loss of about 9.7%, and chemical herbicide becomes the important means that development is efficient, high-quality is agriculture.Along with the mankind more and more pay attention to environment and the health of self, " efficient, low toxicity, safety " has become the theme of new herbicides initiative.
Sulfone pyrrole grass azoles (pyroxasulfone) is found by Japanese K-I chemistry institute and is formulated the earliest, find that it presents remarkable herbicidal effect with the dosage of 100-250g/hm2 to barnyard grass, millet class, lamb's-quarters and millet class grassy weed through dryland soil process, after to be combined by Japanese combinatorial chemistry company and Japanese Buddhist nunnery chemical company and realize industrialization, for the soil treatment of wheat, corn and soybean planting, have the advantages that herbicidal effect is good, using dosage is low, safety is high, 2011 Australia, 2012 America & Canada obtain registration.
Trifluoro grass piperazine (trifludimoxazin), is researched and developed by BASF, belongs to Triazinone weed killer herbicide.ISO agricultural chemicals common name technical committee have approved its new active component common name according to agricultural chemicals common name outline (CPCN) in 2014.Having various crop weeds well kills except effect.
