Embodiment 1

[0043] Weigh 5% fenfentrazone, 25% flufenacet, 8% mesotrione, 6% phenethylphenol polyoxyethylene ether phosphate, 4% sodium alkyl polyoxyethylene ether sulfonate, 5% % polycarboxylate, 1.5% magnesium aluminum silicate, 2% sodium benzoate, 4% ethylene glycol, deionized water added to 100% parts by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 38% oxentrazone·flufenacet·mesotrione suspension concentrate.

Embodiment 2

[0045] Weigh 3% fenfentrazone, 5% flufenacet, 15% mesotrione, 3% sodium lignosulfonate, 5% BY-125, 8% agricultural milk 1601#, 4% sodium alkyl sulfate , 3% polycarboxylate, 1% white carbon black, 1% bentonite, and methyl oleate added 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 a 23% fenflumezone·flufenacet·mesotrione dispersible oil suspension concentrate.

Embodiment 3

[0047] Weigh 1% fenfentrazone, 12% flufenacet, 8% mesotrione, 3% sodium polycarboxylate, 5% Tween-60#, 8% agricultural milk 700#, 6% BY-110 , 1% sodium alkylsulfonate, 0.5% bentonite, 5% propylene glycol, and rapeseed oil added 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 a 26% fenflumezone·flufenacet·mesotrione dispersible oil suspension concentrate.

Abstract

The invention discloses a ternary weeding composition containing topramezone. Effective active ingredients of the weeding composition consist of a first active ingredient topramezone, a second activeingredient flufenacet and a third active ingredient mesotrione. Topramezone accounts for 1%-30% of the weight of the composition, flufenacet accounts for 5%-50% of the weight of the composition, and mesotrione accounts for 1%-20% of the weight of the composition. The ternary weeding composition has reasonable components, the weeding effect on gramineous weeds such as barnyard grass, crab grass andeleusine indica in a corn field and broadleaf weeds such as commelina communis, chenopodium glaucum, piemarker and amaranthus retroflexus is good, the activity and the weeding effect of the weeding composition are not simple superposition of the activity of each component, and compared with the existing single preparation or binary compound preparation, the weeding composition has the advantagesof remarkable weeding effect, remarkable synergistic effect, reduced dosage, enlarged weed control spectrum and high safety to crops.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a three-component herbicidal composition containing fenfentrazone, which is used for weeding cornfields. Background technique [0002] Topramezone, also known as benzopyrazone, its English name is topramezone, and its chemical name is: [3-(4,5-dihydro-3-oxazolyl)-4-methylsulfonyl-2-methyl phenyl]5-hydroxy-1-methyl-1H-pyrazol-4-yl)methanone. Belonging to pyrazolone herbicides, it has a wide herbicidal spectrum and has the control effect on most grass weeds and broad-leaved weeds in corn fields. Purslane, cocklebur, nightshade, etc., but the control effect on crabgrass and barnyardgrass is not ideal. Fenfentrazone can be absorbed by the leaves, roots and stems of weeds, and conduct bidirectionally up and down in the plant body, indirectly affecting the synthesis of carotenoids, interfering with the synthesis and function of chloroplasts under light, and eventually c...
