Embodiment 1

[0045] Formulation Example 1: 70% glufosinate-ammonium and 2,4-D butyric acid dispersible oil suspension concentrate

[0046] Weigh glufosinate-ammonium (10%), 2,4-D butyric acid (60%), calcium dodecylbenzenesulfonate (5%) fatty acid and ethylene oxide condensate (5%), polyoleic acid Oxyethylene ether (5%), bentonite (3%), white carbon black (2%), silicone defoamer (0.03%), and methyl oleate are added to 100% by weight. The above raw materials were mixed and dispersed by high-speed shearing for 30 minutes, and sand-milled with a sand mill for 2-3 hours until the D90 of the granules was less than 10 μm to prepare 70% glufosinate-ammonium·2,4-D butyric acid dispersible oil suspension concentrate.

Embodiment 2

[0047] Formulation example two: 65% glufosinate-ammonium and 2,4-D butyric acid aqueous suspension concentrate

[0048] Weigh glufosinate-ammonium (5%), 2,4-D butyric acid (50%), alkyl naphthalene sulfonate (5%), sodium lauryl sulfate (3%), magnesium aluminum silicate (2 %), xanthan gum (0.3%), polyethylene glycol (3%), silicone defoamer (0.03%), ethylene glycol (2%) and water to make up to 100% by weight. The above raw materials were mixed and dispersed by high-speed shearing for 30 minutes, and then sand-milled with a sand mill for 2-3 hours until the D90 of the granules was less than 10 μm, and a 65% glufosinate-ammonium·2,4-D butyric acid aqueous suspension was prepared.

Embodiment 3

[0049] Formulation example three: 90% glufosinate-ammonium and 2,4-D butyric acid soluble liquid

[0050] Weigh glufosinate-ammonium (60%), 2,4-D butyric acid (30%), alkylphenol and ethylene oxide condensation product OP-10 (3%), alkylphenol polyoxyethylene ether phosphate ( 3%), polyether defoamer (1%), DMF (1%), propylene glycol (1%) and water to make up to 100% by weight. Put the above raw materials into the blending kettle, start the mixer, and after stirring evenly, prepare 90% glufosinate-ammonium and 2,4-D butyric acid soluble liquid.

Abstract

The invention relates to a herbicidal composition. The herbicidal composition is prepared from glufosinate and 4-(2,4-dichlorophenoxy)butyric acid or a derivative thereof, wherein the mass ratio of glufosinate to 4-(2,4-dichlorophenoxy)butyric acid or a derivative thereof is (1 to 100):(100 to 1), preferably (3 to 10):10, the two active ingredients have a significant synergistic effect after compounding. The invention further relates to dispersible oil suspensions, aqueous suspensions, soluble liquids, microemulsions, or aqueous emulsions made from the above herbicidal compositions. The phenomenon that the pesticide effect of the glyphosate at low temperature is poor is alleviated, and the problem that the glufosinate in the preparation of the suspension dosage form has a paste during heattreatment after grinding is overcome. According to the herbicidal composition and the pesticide preparation containing the herbicidal composition provided by the invention expand the herbicidal spectrum, the herbicidal activity is improved, the defect of single agents on main weeds is compensated for, the lasting effect is long, the safety to crops is high, and the application frequency and the application cost are effectively reduced, and the economic benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a synergistic herbicidal composition containing two active ingredients of glufosinate-ammonium, 2,4-D butyric acid and its derivatives, and a dispersible oil suspension concentrate, water Suspension, soluble liquid, microemulsion, water emulsion or emulsifiable concentrate. Background technique [0002] Glufosinate-ammonium (glufosinate-ammonium) is an organophosphorus non-conductive herbicide with glutamine synthetase (GS) as the target enzyme created by Hoechst, Germany. Its active ingredient is phosphinothricin (PPT), chemical The name is (RS)-2-amino-4-(hydroxymethylphosphinyl)ammonium butyrate. Glufosinate-ammonium is safe for crops, not easy to drift, and has a wide range of weeding, high activity, environmental friendliness, and easy degradation in soil. Therefore, it is widely used in orchards, vineyards, non-arable land, potato fields, etc. to control annual and perenn...
