Embodiment 1

[0017] Formulation Example 1: 50% acesulfame·aminopyralid potassium salt·metutrazone water-dispersible granules.

[0018]

[0019] Put the above materials together into the conical mixer and mix them evenly, and then crush them through the jet mill, and then mix the crushed materials through the conical mixer. Knead into a plastic material, and finally put the material into an extrusion granulator to extrude and granulate. After granulation, dry and sieve to obtain 50% acesulfame · aminopyralid potassium salt · carfentrazone Ketone water dispersible granules.

Embodiment 2

[0020] Formulation example 2: 40% acesulfame·aminopyralid sodium salt·metutrazone wettable powder.

[0021]

[0022]

[0023] Add the above materials together into a conical mixer and mix them evenly, then pulverize them through a jet mill, and then mix the pulverized materials through a conical mixer. The fineness of the mixed materials is 98% and passes through a 600-mesh standard sieve to obtain 40% Acesulfame · Ampicillin Sodium Salt · Methazone WP.

[0024] Formulation Example 3: 35% acesulfame·aminopyralid·meflutrazone suspension concentrate.

[0025]

[0026] The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and then prepared after high-shear mixing to obtain a 35% acesulfame·aminopyralid·metuflumezone suspension concentrate.

Embodiment 4

[0027] Formulation example 4: 28% acesulfame·aminopyralid·metrazone oil suspension

[0028]

[0029]

[0030] Put the above materials (except organic bentonite) into the reaction kettle mixer together, stir for 2 hours, open the feed valve at the bottom of the kettle, inject the materials into the multi-stage sand mill for grinding, and the fineness of the ground materials is 98% through 1- After 5um, the material is discharged, and the material is put into a high-shear emulsification kettle together with the pre-dissolved organic bentonite. After emulsification, it can be made into 28% acesulfame, aminopyralid, and mefentrazone with good flowability. oil suspension.

[0031] Biological Assay Example 1: Indoor toxicity test of acesulfame, aminopyralid, mefentrazone and their compound pairs of shepherd's purse (Capsella bursa-pastoris) and Descurainia sophia.

[0032] According to the Colby method to evaluate the combination of herbicides (NY / T 1155.7-2006), the formula ...

Abstract

The invention relates to a wheat paddock weed killer. Effective components are pyroxsulam, aminopyralid (or a salt compound thereof) and carfentrazone. The weed killer disclosed by the invention has a synergistic interaction effect, obviously has a better effect of killing the manual weeds of a wheat paddock than a single agent which is used independently and has the advantages of widening the weed killing spectrum, delaying generation of drug resistance of the weeds and alleviating the environmental pollution, and being reduced in dosage.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicide with acesulfame, aminopyralid (or its salt compound) and mefentrazone as active ingredients, especially for shepherd's purse and Artemisia annua. The synergistic effect is suitable for the control of annual weeds in wheat fields, especially the annual weeds in wheat fields where shepherd's purse and Artemisia indica are the dominant weeds. Background technique [0002] Pyroxsulam (pyroxsulam) sulfonamide systemic conduction type, selective winter wheat field post-emergence herbicide, broad herbicidal spectrum, high herbicidal activity, fast drug effect. The drug is absorbed by weed leaves, sheaths, stems or roots, accumulates at growth points, inhibits acetolactate synthase, and cannot synthesize branched-chain amino acids, which in turn affects protein synthesis and weed cell division, causing weeds to stop growing, It turns yellow and then dies. It h...
