Abstract

The invention relates to a synergistic weeding composition containing fluroxypyr. The composition is a ternary compound herbicide composition using fluroxypyr, carfentrazone-ethyl and MPCA sodium as active components, wherein a weight ratio of fluroxypyr to carfentrazone-ethyl to MPCA sodium is 1-60: 1-40: 10-80, and the composition may be prepared to form a wettable powder, a water-dispersible granule, an oil flowable concentrate, a suspoemulsion, a micron emulsion and an emulsion in water. The synergistic weeding composition provided by the invention is used for preventing and treating broad-leaf weeds, grassy weeds and cyperaceae weeds in corn fields and wheat fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic herbicidal composition containing fluroxypyr, which is used for preventing and controlling common weeds in corn fields and wheat fields. Background technique [0002] In recent years, the direction of pesticide development is to embody high efficiency, low toxicity, low residue and no pollution. The specific performance is the pursuit of "three highs", that is, (1) high safety, which not only requires low toxicity, low residue, and pollution-free; (2) high biological activity; (3) high selectivity. Therefore, continue to improve the performance of the current pesticide products to meet the requirements of high efficiency, low toxicity and no pollution. Therefore, choosing a compound mixture of pesticides has become the current first choice and an effective way. By adjusting the ratio of different pesticides, the best synergistic effect can be obtaine...
