Embodiment 1

[0018] This example provides the preparation of 10% cycloclofen-cyclocenzazone suspension concentrate.

[0019] In terms of parts by mass, every 100 parts of Cyclofenac-Cyclotrione Suspension Contains, 5 parts of Cycloclofenac, 5 parts of Cyclobucilone, 5 parts of calcium dodecylbenzenesulfonate, 5 parts of lignosulfonate 3 parts of hydrochloric acid, 20 parts of dibutyl phthalate, 0.5 parts of butanol, 0.8 parts of polyvinyl alcohol, and 60.7 parts of sterile water.

[0020] Weigh each component according to the above-mentioned parts by mass, add cyclamate, cyclazone, calcium dodecylbenzenesulfonate, lignosulfonate, butanol, and polyvinyl alcohol into the scrubbing kettle, and grind to a certain After the fineness is obtained, transfer the material to a stirring tank, add the remaining dibutyl phthalate and sterile water, and mix thoroughly to obtain a 10% cycloclofen-cyclobenzazone suspension concentrate.

Embodiment 2

[0022] This example provides the preparation of 10% cycloclofenac·clocloflume EC.

[0023] In terms of parts by mass, every 100 parts of cycloclofenac-cycloxytrione emulsifiable concentrate contains 6 parts of cycloclofenac, 4 parts of cycloclofenone, 25 parts of Nongru 400#, 45 parts of N-methylpyrrolidone, 17.5 parts of industrial vegetable oil, 2.5 parts of epichlorohydrin.

[0024] Weigh each component according to the above-mentioned parts by mass, add cycloheptadin and cycloclotrione into N-methylpyrrolidone, mix well, add industrial vegetable oil, agricultural milk 400# and epichlorohydrin in sequence, and stir well into a uniform transparent oily liquid to obtain 10% Cycloclofen-Cyclobucilone EC.

Embodiment 3

[0026] This example provides the preparation of 30% Cycloclofen·Cycloclotrione water-dispersible granules.

[0027] In terms of parts by mass, every 100 parts of Cyclofenac-Cyclotrione water-dispersible granule contains 20 parts of Cycloclofenac-10 parts, 10 parts of Cycloclofenone, 2 parts of lignocarbonsulfonate, dodecane 3 parts of sodium sulfate, 5 parts of sodium sulfate, 5 parts of polyethylene glycol, and 55 parts of kaolin.

[0028] Weigh each component according to the above parts by mass, put the material into the mixer and mix evenly, then pulverize it through the jet mill, pass through a 600-mesh standard sieve, add it into the kneader to knead into a plastic material, and finally put the material into extrusion granulation Squeeze and granulate in the machine, dry and sieve after granulation to obtain 30% Cycloclofen-Cyclobutrione water-dispersible granules.

Abstract

The invention provides a pyriftalid-containing weeding composition. The active ingredients of the pyriftalid-containing weeding composition comprise pyriftalid and profoxydim, and the mass ratio of pyriftalid to profoxydim in the weeding composition is (20: 1)-(1: 10). Within the ratio range, the composition not only has a remarkable control effect on gramineous weeds, broadleaf weeds and cyperaceae weeds in a rice field, but also has a certain control effect on wild oats and amur foxtail in a wheat field, is suitable for control of weeds in a crop rotation field, is safe and harmless to crops and human bodies, and is suitable for large-area use and popularization.

Description

technical field [0001] The invention belongs to the technical field of agricultural compositions, and relates to a herbicide, in particular to a herbicide composition containing cyclamate. Background technique [0002] In recent years, with the change of rice cultivation system, the application area of ​​rice light cultivation technology has been expanding. At the same time, the harm of weeds in rice fields is also becoming more and more serious, which seriously affects the production of rice. Therefore, it is necessary to choose a safe, effective and economical herbicide to solve the harm of weeds in paddy fields. [0003] Pyriftalid (English name: pyriftalid) is a broad-spectrum herbicide used in the early post-emergence stage of rice. It belongs to the class of pyrimidine oxy (thio) benzoic acid herbicides, and its structure is similar to pyrimidine hydroxybenzoic acid. Its mechanism of action is to inhibit the synthesis of acetolactate synthase (ALS). It is specially ...
