Problems solved by technology

It is mainly used to control gramineous weeds in rice fields such as barnyardgrass, blue horsegrass, crabgrass, daughter of a daughter, foxtail, and cyperus. It is safe for direct-seeding rice and transplanting rice; but for broad-leaf and sedge The control effect is not ideal
[0004] Although both oxazicone and cyclazone can control weeds in paddy fields, due to the occurrence of drug resistance in the process of use, and the range of resistance expands year by year, the control effect decreases year by year, which leads to the single-component damage to paddy fields. The comprehensive control effect of total weeds is low, and the purpose of weeding cannot be achieved

Abstract

The invention discloses a weeding composition containing oxaziclomefone and profoxydim. The effective components of the weeding composition are the profoxydim and the oxaziclomefone, wherein a mass ratio of the oxaziclomefone to the profoxydim is (8-30): (7.5-40). The weeding composition disclosed by the invention has a synergistic effect, is mainly used for gramineae weeds, nutgrass flatsedge weeds, broadleaf weeds and the like in paddy fields, and has a special effect on barnyard grass and moleplant seeds. Through compounding, the dosage of the composition can be reduced, high safety is realized, pesticide application frequency is decreased, pesticide application cost is lowered; and the composition also can control a weed population change, reduce the drug resistance of weeds, maintainagricultural ecological balance and protect the environment, so the compounding of the the profoxydim and the oxaziclomefone is worth popularizing.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides, and in particular relates to a herbicidal composition containing oxazone and cycloclozone. Background technique [0002] Oxaziclomefone, English name oxaziclomefone, CAS registration number 153197-14-9, oxaziclomefone is a systemic organic heterocyclic herbicide for paddy fields, absorbed by the roots and stems and leaves of weeds The herbicidal mechanism of other herbicides inhibits the growth of target plant cells, causing the stems and leaves to lose chlorosis, stop growing, and die. Through biochemical tests, we know that oxaziclozone and known herbicides inhibit respiration, photosynthesis, DNA biochemical synthesis, RNAChemicalbook biochemical synthesis, protein biochemical synthesis, lipid biochemical synthesis, fatty acid synthase, ACc enzyme The mechanism of action of inhibition, amino acid biochemical synthesis inhibition and asparagine synthase inhibition is inconsistent,...
