Problems solved by technology

For many years, the chemical pesticides used to control weeds in wheat fields mainly use a few herbicide varieties represented by tribenuron-methyl. Due to long-term repeated or unscientific use of these agents, the resistance of weeds in wheat fields is serious (such as Artemisia sobas to bensulfone Long resistance is already very serious), so the dosage increases, resulting in higher control costs, increased residues, and increased environmental and ecological risks

Embodiment 1

[0032] 10% to 40% of the composition, 10% to 20% of the surfactant sodium dodecylbenzenesulfonate, polyethylene glycol phenolic phosphate and alkylphenol polyoxyethylene ether, and the rest of the liquid carrier acetone, placed in a stirrer Mix evenly to get the composition emulsifiable cream.

Embodiment 2

[0034] Formulated composition:

[0035] Composition 10-80%, surfactant naphthalene sulfonate formaldehyde condensate, alkylnaphthalene sulfonate formaldehyde condensate and sodium lauryl sulfate 10-20%, white carbon black 5-10%, kaolin balance , stir evenly, pulverize with a high-speed airflow mill until the particle size of the material reaches 325 mesh, and then mix evenly to obtain a wettable powder of the composition.

Embodiment 3

[0037] Composition 10-60%, surfactant alkylphenol polyoxyethylene ether, lignin sulfonate and alkylnaphthalene sulfonate formaldehyde condensate 10-25%, white carbon black 10-15%, calcium chloride and 10-15% ammonium sulfate, stirred evenly, put into a ball mill for rough grinding, and then put into a sander for fine grinding until the particle size of the material reaches 325 mesh, and then dry in a spray drying tower to obtain a dry suspension concentrate of the composition.

Abstract

The invention relates to the technical field of plant protection, particularly to a clacyfos-containing herbicide composition and applications in prevention and removal of agricultural weeds. The herbicide composition contains an active component A and an active component B, wherein the active component A is clacyfos, the active component B is selected from halosulfuron-methyl, iodosulfuron-methylsodium, amidosulfuron, chlorimuron-ethyl, cyclosulfamuron, flucarbazone-sodium, prosulfuron, tritosulfuron, mesosulfuron-methyl, propoxycarbazone-sodium, pyroxsulam, flumetsulam, florasulam and the like, and a mass ratio of the active component A to the active component B is 1:(0.001-100). The clacyfos-containing herbicide composition is small in dosage and high in prevention effect, relieves theburden of the environment, is safe to people, livestock, beneficial organisms and environmental ecology, and meets the requirement of sustainable development.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to a glufosinate-containing herbicide composition and application thereof. Background technique [0002] Chlorophosphine: the chemical name is O, O-dimethyl-1-(2,4-dichlorophenoxyacetoxy) ethyl phosphonate, and the molecular formula is C 12 h 15 Cl 2 o 6 P, developed by Central China Normal University, is a new type of herbicide with independent intellectual property rights in my country. It belongs to substituted phenoxyacetoxyalkyl phosphonate compounds and is a strong inhibitor of pyruvate dehydrogenase system. Chlorophosphate has a novel structure, high activity, broad herbicidal spectrum, strong systemic property, low toxicity, low residue, and environmental ecological safety. It is currently the only commodity that targets the pyruvate dehydrogenase system herbicides. As a selective herbicide, glufosinate chloride has good application and development prospects in...
