Embodiment 1

[0018] Formulation example 1: 46% florasulam·aminopyralid potassium salt·dimethyltetrachlorosodium water dispersible granules.

[0019]

[0020] 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, it is dried and sieved to obtain 46% florasulam·aminopyralid·dimethazine Sodium chloride water dispersible granules.

Embodiment 2

[0021] Formulation Example 2: 37% florasulam·aminopyralid sodium salt·2,4-D-butyl ester water-dispersible granules.

[0022]

[0023] 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 this material into an extrusion granulator to extrude and granulate. After granulation, dry and sieve to obtain 37% florasulam · aminopyralid sodium salt 2 , 4-D butyl ester water dispersible granules.

Embodiment 3

[0024] Formulation Example 3: 27% florasulam·aminopyralid·dimethyltetrachloroisooctyl wettable powder.

[0025]

[0026] 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 27% Flusulam·aminopyralid·dimethyltetrachloroisooctyl wettable powder.

Abstract

The invention relates to a herbicide composition for a wheat field. The herbicide composition contains effective components including florasulam, aminopyralid (or salt compounds of aminopyralid) and a phenoxy carboxylic acid herbicide, wherein the phenoxy carboxylic acid herbicide is one selected from 2-methyl-4-chlorophenoxyacetic acid, 2-methyl-4-chlorophenoxyacetic acid sodium salt, 2-methyl-4-chlorophenoxyacetic acid-isooctyl, 2,4-D, 2,4-D butyl ester and 2,4-D isooctyl ester. The herbicide composition disclosed by the invention has a synergistic effect and is remarkably better than each independently-used agent in effect on preventing and removing annual weeds in the wheat field; and by using the herbicide composition, the herbicide controlling spectrum is widened, meanwhile, the dosage is reduced, the generation of herbicide resistance of the weeds is delayed, and the environment pollution is relieved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition with florasulam, alanopyral (or its salt compound), and phenoxycarboxylic acid herbicides as active ingredients, which is suitable for controlling wheat fields In particular, the annual weeds in wheat fields are dominated by shepherd's purse (Capsella bursa-pastoris), geranium wilfordii, thistle (Cirsium setosum) and Descurainia sophia. Background technique [0002] Flumesulam (florasulam) Flumesulam is a super efficient herbicide of triazolopyrimidine sulfonamide, and florasulam is a systemic conduction herbicide, which can be transmitted to the whole plant of weeds, thus killing weeds Thorough, no relapse, stable efficacy at low temperature, even at 2°C, stable efficacy can still be guaranteed, florasulam has a broad herbicidal spectrum, and can control most broad-leaved weeds in wheat fields, including pig scorpion (Rubiaceae), Maijiago...
