Problems solved by technology

[0007] Imperata praecox, red thistle, iron mango, and spinosa are common weeds in a variety of crop fields and non-cultivated land. Using glyphosate, fluroxypyr and mefentrazone alone cannot control these weeds at the same time. Weeds, and in actual application, the weeding speed of glyphosate and fluroxypyr iso-octyl alone is slow, and it is easily affected by bad weather such as low temperature and rainfall, which limits the efficacy of the medicine

Embodiment 1

[0033]By weight percentage, glyphosate 30%, fluroxypyr isooctyl 12%, fenflurzone 10%, sodium lauryl sulfate 10%, sodium lignosulfonate 10%, methylenebis Sodium naphthalenesulfonate 8%, the balance is white carbon black. First add white carbon black and mefentrazone into the mixer and mix evenly, then add glyphosate, fluroxypyr isooctyl, sodium lauryl sulfate, sodium lignin sulfonate and methylene bis-naphthyl Sodium sulfonate is sequentially added into a mixer and fully mixed, and the uniformly mixed material is added into a jet mill and pulverized until the fineness reaches 325 mesh, and a composition wettable powder with an active ingredient content of 52% is obtained.

Embodiment 2

[0034] Example 2 (66% glyphosate · fluroxypyr isooctyl · fenflurzone wettable powder):

[0035] By weight percentage, glyphosate 60%, fluroxypyr isooctyl 4%, fenflurzone 2%, sodium lauryl ether sulfate 2%, calcium lauryl sulfate 2%, lauryl Sodium benzenesulfonate 4%, balance is light calcium carbonate. First add light calcium carbonate and fenflurzone into the mixer and mix evenly, then add glyphosate, fluroxypyr isooctyl, sodium lauryl ether sulfate, calcium lauryl sulfate and lauryl Sodium benzenesulfonate is sequentially added into a mixer and fully mixed, and the uniformly mixed material is added into a jet mill and pulverized until the fineness reaches 325 mesh, and a composition wettable powder with an active ingredient content of 66% is obtained.

Embodiment 3

[0036] Example 3 (83% glyphosate · fluroxypyr isooctyl · fenflurzone wettable powder):

[0037] By weight percentage, glyphosate 70%, fluroxypyr isooctyl 12%, mefentrazone 1%, sodium alkanolamide polyoxyethylene ether sulfonate 2%, fatty alcohol polyoxyethylene ether sulfonic acid Sodium 2%, sodium dodecylbenzene sulfonate 1%, the balance is attapulgite. First add attapulgite and mefentrazone into the mixer and mix evenly, then add glyphosate, fluroxypyr isooctyl, sodium alkanolamide polyoxyethylene ether sulfonate, fatty alcohol polyoxyethylene ether sulfonate Sodium dodecylbenzenesulfonate and sodium dodecylbenzenesulfonate were successively added to the mixer and fully mixed, and the uniformly mixed material was added to the jet mill and pulverized until the fineness reached 325 meshes, and a composition with an active ingredient content of 83% was obtained. powder.

Abstract

The invention discloses a weedicide composition containing glyphosate, fluroxypyr-meptyl and carfentrazone-ethyl. The composition contains the active weedicide components of glyphosate, fluroxypyr-meptyl and carfentrazone-ethyl. Based on the weedicide composition, the composition comprises the following components in percentage by weight: 30-70% of glyphosate, 1-15% of fluroxypyr-meptyl, 1-10% of carfentrazone-ethyl and the balance of assistant. The preparation formulation of the weedicide composition can be wettable powder, water-dispersible granules, a water emulsion and a microemulsion. The composition has obvious synergistic action after being complexed, enlarges the weed control spectrum, improves the weeding speed and remarkably reduces the consumption and use frequency of the weedicide, and can be used for controlling weeds such as cogongrass, Ageratum conyzoides, Diranopteris dichotoma, Alternanthera philoxeroides and the like.

Description

technical field [0001] The present invention relates to a pesticide composition, especially a herbicide composition with glyphosate, fluroxypyr-isooctyl and fenflurzone as active ingredients. The pesticide composition can be used to control Imperata cylindrica, Red thistle Ageratum conyzoides, Dicranopteris dichotoma, Alternantheraphiloxeroides and other weeds. technical background [0002] Glyphosate is also known as Roundup and Zhencaoning. The English common name is glyphosate, CA registration number: 1071-83-6, and the chemical name is N-(phosphomethyl)glycine. Molecular formula C 3 h 8 NO 5 P, molecular weight 169.09. It is an organophosphorus herbicide and a systemic herbicide absorbed by stems and leaves. It mainly inhibits enolacetonyl shikimelin phosphate synthase in the body, thereby inhibiting the conversion of shikime to phenylalanine and tyrosine And the transformation of tryptophan, the protein synthesis is interfered and the plant dies, and it can be used...
