Fenoxaprop-p-ethyl and fluroxypyr-mepthyl-containing composition and application

Abstract

The invention discloses a fenoxaprop-p-ethyl and fluroxypyr-mepthyl-containing composition. The composition comprises two effective components, namely fenoxaprop-p-ethyl and fluroxypyr-mepthyl; a massratio of the fenoxaprop-p-ethyl to the fluroxypyr-mepthyl ranges from (1:1) to (5:6); the total mass percentage of the fenoxaprop-p-ethyl and the fluroxypyr-mepthyl in the composition is 3 to 75 percent, and the composition comprises the balance of auxiliary components added during pesticide use. The weeding composition and a preparation thereof which are provided by the invention take the fenoxaprop-p-ethyl and the fluroxypyr-mepthyl as the effective components; when the fenoxaprop-p-ethyl and the fluroxypyr-mepthyl are proportioned according to a certain proportion, the composition is better in weeding effect than a single-agent herbicide containing effective components with the same mass.

Description

technical field [0001] The invention relates to the technical field of pesticide compositions, in particular to a composition containing fenoxaprop-p-ethyl and isooctyl fluroxypyr and its application. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs are mixed, but also the emergence of weeds is uneven, and the seeds, young and old weeds are staggered, so the herbicide species alone When used, all will show some defects and limitations. [0003] Fluroxypyr iso-octyl is an organic heterocyclic selective systemic conduction post-emergence herbicide, which is suitable for controlling various broad-leaved weeds in fields of grass crops such as wheat, barley, and corn.

At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs are mixed, but also the emergence of weeds is uneven, and the seeds, young and old weeds are staggered, so the herbicide species alone When used, it will show some defects and limitations

[0003] Fluroxypyr iso-octyl is an organic heterocyclic selective systemic conduction post-emergence herbicide, which is suitable for controlling various broad-leaved weeds in fields of grass crops such as wheat, barley, and corn. Octyl esters can control various broad-leaved weeds such as pig vines, purslane, solanum nigrum, chickweed, fruit and vegetable field bindweed, vetch, wormwood and bindweed, and grasses and sedges family weed invalid
