Weeding composition containing fenoxaprop-p-ethyl and bispyribac-sodium

Abstract

The invention discloses a weeding composition containing fenoxaprop-p-ethyl and bispyribac-sodium. The weeding composition contains fenoxaprop-p-ethyl and bispyribac-sodium as active ingredients, and the balance being pesticide additives, wherein the mass part ratio of fenoxaprop-p-ethyl to bispyribac-sodium is (1:20)-(20:1); the total mass of fenoxaprop-p-ethyl and bispyribac-sodium accounts for 5-50% of the mass percentage of the composition. According to a conventional pesticide processing technique, the weeding composition can be prepared into wettable powder and suspending agents, and can be applied to preventing annual weeds in rice fields.

Description

technical field [0001] The paddy field herbicidal composition related to the present invention uses fenoxaprop-p-ethyl and bispyriben as active ingredients, and is used for controlling annual weeds in paddy fields. Background technique [0002] Fenoxaprop-P-P is an aryloxyphenoxypropionic acid herbicide and is an inhibitor of fatty acid synthesis. After being absorbed by the leaves of plants, it is transported to the leaf base, stems, and roots, and inhibits the biosynthesis of fatty acids in gramineous plants, hindering the growth of plant growth points, reducing the chlorophyll content in leaves, and free amino acids in stems and leaf tissues. Soluble sugars increase, the plant's normal metabolism is disrupted, and eventually sensitive plants die. It can be quickly metabolized in broad-leaved crops or broad-leaved weeds. It is quickly decomposed in the soil and has no effect on subsequent crops. [0003] Bispyribac inhibits the synthesis of acetic acid through the absor...
