Embodiment 1

[0050] Weigh 15% fluclopyridine, 35% methylsulfuron-methyl, 10% acesulfame, 10% mefenpyr-ethyl, 4% alkylnaphthalene formaldehyde condensate calcium sulfonate, 5% alkylphenol poly Sodium oxyethylene ether sulfonate, 2% sodium alkylnaphthalene sulfonate, 5% talc, and kaolin are added to 100% by weight. The above-mentioned raw materials are mixed and air-jet pulverized to obtain 60% mesosulfuron-halfafen-apymesulam wettable powder.

Embodiment 2

[0052] Weigh 5% fluclopyridine, 20% methylsulfuron-methyl, 20% acesulfame-methyl, 5% mefenpyr-ethyl, 5% alkylnaphthalene formaldehyde condensate calcium sulfonate, 6% alkylphenol polysulfone Sodium oxyethylene ether sulfonate, 3% sodium alkylnaphthalene sulfonate, 5% talc, and diatomaceous earth are added to 100% by weight. The above raw materials are mixed and air-jet crushed to obtain 45% mesosulfuron-fluoropyridine-acymesulam wettable powder.

Embodiment 3

[0054] Weigh 30% fluclopyridine, 25% mesosulfuron-methyl, 5% acesulfame, 8% mefenpyr-ethyl, 4% sodium lignosulfonate, 5% fatty alcohol polyoxyethylene ether phosphate , 4% sodium polycarboxylate, 3% sodium alkyl sulfate, 3% white carbon black, and talc powder added to 100% by weight. The above-mentioned raw materials are mixed and air-jet pulverized to obtain a 60% wettable powder of haclopyridin-methylsulfuron-sulfuron and acesulfame.

Abstract

The invention discloses a ternary herbicidal composition containing halauxifen-methyl and application of the ternary herbicidal composition. The ternary herbicidal composition is prepared from the following active ingredients: a first active ingredient halauxifen-methyl, a second active ingredient mesosulfuron-methyl and a third active ingredient pyroxsulam, wherein a mass ratio of halauxifen-methyl to mesosulfuron-methyl to pyroxsulam is (1-90):(1-90):(1-90); the composition can be prepared into agriculturally allowable water dispersible granules, wettable powders, suspensions and dispersible oil suspensions. The ternary herbicidal composition provided by the invention is reasonable in ingredient, has good herbicidal effect in wheat fields, and has activities and herbicidal effects not a simple sum of activities of all ingredients; compared with conventional single preparation or binary compound preparation, the ternary herbicidal composition has significant synergistic effect besides significant herbicidal effect, and is lower in dosage, wider in herbicidal spectrum and safer to crops.

Description

technical field [0001] The invention relates to a wheat field herbicidal composition, which is composed of active ingredients such as haclopyridine, mesosulfuron-methyl, acesulfame and auxiliary agents, and belongs to the technical field of compound pesticides. Background technique [0002] Halauxifen-methyl, the English name is halauxifen-methyl. It is an active ingredient developed by Dow AgroSciences, which can be used as a picolinate herbicide. The ISO common name of this active ingredient was approved in November 2012. Dow AgroSciences has marketed the compound's haclopyridine methyl ester and launched it in the Canadian cereal crop market for post-emergence broadleaf weed control. Haclopyralid is the first product of a new chemical class of arylpyralidic acids among synthetic auxin herbicides. It mimics the effects of high doses of natural auxin, causing overstimulation of specific auxin-regulated genes, interfering with multiple growth processes in sensitive plants....
