Problems solved by technology

[0007] Using any one of the above one-component herbicides alone is not only costly, but also has a narrow herbicidal spectrum, making it difficult to achieve the effect of controlling multiple weeds at one time, and the application procedure is cumbersome, time-consuming and labor-intensive

Embodiment 1

[0026] Example 1: 62% Bensulfuron-methyl Metozalam Water-Dispersible Granules

[0027] Weigh 60% bensulfuron-methyl, 2% metofen, 3% diffusing agent NNO (alkylnaphthalene sulfonate formaldehyde condensate), 2% sodium lignosulfonate, 1% pull-off powder BX (dibutyl Sodium naphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% carboxymethyl cellulose, 0.1% xanthan gum, 8% diatomaceous earth, light calcium carbonate add to 100% parts by weight . 62% Bensulfuron-methyl-Metozazone water-dispersible granules were prepared by the conventional method for preparing water-dispersible granules from the above-mentioned raw materials, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

Embodiment 2

[0028] Example 2: 35% bensulfuron-methyl-metafluna suspending concentrate

[0029] Weigh 30% bensulfuron-methyl, 5% mefentrazone, 3% sodium lignosulfonate, 3% TERSPERSE4894, 4% sodium lauryl sulfate, 0.1% xanthan gum, 4% ethylene glycol, 0.5% Add sodium benzoate, 0.4% organosilicon defoamer, and deionized water to 100% to prepare a 35% bensulfuron-methyl-metafluna suspending agent.

Embodiment 3

[0030] Example 3: 51% Bensulfuron-methyl Metozalam WP

[0031] Weigh 1% bensulfuron-methyl, 50% metoxazone, 4% ERSPERSE2700, 2% pull-off powder BX, 4% sodium dodecylsulfonate, 3% talcum powder, and clay to make 100% by weight. The above-mentioned raw materials were mixed and air-jet pulverized to obtain 51% bensulfuron-methyl-metafluna wettable powder.

Abstract

The invention discloses herbicide composition containing cafenstrole. The herbicide composition comprises active ingredients including a sulfonylurea herbicide and the cafenstrole in the weight ratio being 30:1-1:50. Bensulfuron methyl or pyrazosulfuron-ethyl and the cafenstrole are compounded in a certain ratio, the composition comprises reasonable components, has the control effect superior to activity of each component when the components are applied separately, and has the synergistic effect, besides, the weed control spectrum is broadened, and grassy, sedge and broadleaf weeds in paddy fields are controlled through one-time application of the composition; meanwhile, the number of application times is decreased, the control cost is reduced, production of resistance of the weeds is retarded, and the composition has good safety for crops and meets safety requirements of pesticide preparations.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide composition containing carfentrazone. technical background [0002] With the phase-out of highly toxic pesticides, new pesticides with high efficiency, low toxicity, safety and environmental friendliness are needed. At the same time, the long-term use of pesticides has resulted in resistance to pests and weeds, and the requirements for control chemicals are also getting higher and higher. It is necessary for pesticide research and development personnel to develop more efficient and safe new agents to meet the control requirements. Since the creation of pesticides in my country has just started, and the varieties of pesticides with independent intellectual property rights can not meet the needs, therefore, the development of new pesticide mixed preparations is the only way for the current development of pesticides. [0003] Rice is one of the main food crops in my ...
