Embodiment 1

[0026] Weigh 3% isoxaflutole, 12% metolachlor, 3% mesotrione, 5% sodium lignosulfonate, 7% sodium alkyl polyoxyethylene ether sulfonate, 4% polyethylene alcohol, 2% bentonite, 3% isothiazolinone, 1% potassium sorbate, 1% octanol, and deionized water to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare 18% isoxaflutole · refined metolachlor · mesotrione suspension concentrate.

Embodiment 2

[0028] Weigh 6% isoxaflutole, 18% refined metolachlor, 6% oxaflumele, 4% polyoxyethylene polyoxypropylene ether block copolymer, 5% sodium polycarboxylate, 1% Carboxyethyl cellulose, 6% sorbitol, 0.8% formaldehyde, 0.4% hexanol, and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed by high-speed shearing for 30 minutes, and sanded with a sand mill to prepare a 30% isoxaflutole · refined metolachlor · oxaflutole suspension concentrate.

Embodiment 3

[0030] Weigh 4% isoxaflutole, 8% refined metolachlor, 2% mesotrione, 6% diffusing agent NNO, 4% TERSPERSE 2020, 5% Span-60#, 5% emulsifier BY -110, 3% sodium alkyl sulfate, 1.3% bentonite, 2% urea, rapeseed oil added to 100% by weight. The above-mentioned raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare 14% isoxaflutole · refined metolachlor · mesotrione dispersible oil suspension concentrate.

Abstract

The invention discloses a ternary weeding composition containing isoxaflutole and application thereof. The effective active components are composed of the first active component isoxaflutole, the second active component s-metolachlor and the third active component mesotrione or topramezone. The weight ratio of isoxaflutole to the composition is 1-20%, the weight ratio of s-metolachlor to the composition is 10-40%, and the weight ratio of mesotrione or topramezone to the composition is 1-20%. The composition can be prepared into a suspension agent, a dispersible oil suspension agent, wettable powder, water dispersible granules, an emulsion in water and a microemulsion which are agriculturally allowable. The composition is reasonable in component and has a good weeding effect on gramineous weeds such as echinochloa crusgalli, setaria viridis and eleusine indica and broad-leaf weeds such as commelina communis, polygonum lapathifolium and portulaca oleracea in corn field, and the activityand weeding effect of the composition is not simple superposition of the activity of all the components. Compared with existing monotonous preparations or binary compound preparations, the compositionhas the obvious weeding effect and further has the obvious synergistic effect, the pesticide application amount is low, the weed control spectrum is large, and the crop safety is good.

Description

technical field [0001] The invention relates to a cornfield herbicide composition, which is composed of active ingredients isoxaflutole, refined metolachlor, mesotrione or oxentrazone and auxiliary agents, and belongs to the technical field of compound pesticides. Background technique [0002] Isoxaflutole, the English name is isoxaflutole, the chemical name is 5-cyclopropyl-1,2-oxazol-4-yl-a,a,a-trifluoro-2-methylhydrazinesulfonyl-p-toluene ketone. Isoxaflutole is a p-hydroxyphenylpyruvate dioxygenase inhibitor, that is, an HPPD inhibitor. Its action is characterized by broad-spectrum herbicidal activity, can be used before and after emergence, and the weeds will die after albinism. Although its symptoms are very similar to those of carotenoid bioinhibitors, its chemical structure characteristics such as polarity and degree of ionization are significantly different from those of known carotenoid bioinhibitors. By inhibiting the synthesis of p-hydroxyphenylpyruvate dioxyge...
