Embodiment 1）

[0026] The dosage form of the paddy field herbicide composition of the present embodiment is a dry suspension concentrate, which consists of the following components by weight: 10 parts by weight of carfentrazone-ethyl, 50 parts by weight of bispyribac, 6 parts by weight of Sodium butylnaphthalene sulfonate of agent, 5 parts by weight of sodium lignosulfonate as dispersant, 2 parts by weight of urea as disintegrant, 1 part by weight of sodium carboxymethylcellulose as binder, 11 parts by weight of light calcium carbonate as a carrier and 15 parts by weight of white carbon black as a carrier. The parts by weight of each component listed above are also called formulas. In the above components, carfentrazone-ethyl and bispyribac are active components, and wetting agents, dispersants, disintegrants and binders are auxiliary agents.

[0027] The above-mentioned carfentrazone-ethyl and bispyriben as active components are all from Jiangsu Agricultural Hormone Engineering Technology ...

Embodiment 2）

[0030] The dosage form of the rice field herbicide composition of the present embodiment is a wettable powder, which consists of the following components by weight: 10 parts by weight of carfentrazone-ethyl, 15 parts by weight of bispyribac, 6 parts by weight of Alkylphenol polyoxyethylene ether of agent, 3 parts by weight of sodium lignosulfonate as dispersant, 60 parts by weight of light calcium carbonate as carrier and 6 parts by weight of white carbon black as carrier. The parts by weight of each component listed above are also called formulas. In the above components, carfentrazone-ethyl and bispyribac are active components, and the wetting agent and the dispersing agent are auxiliary agents.

[0031] The sources of the above-mentioned carfentrazone-ethyl, bisfluorin, sodium lignosulfonate, light calcium carbonate and white carbon black are the same as those in Example 1. The above-mentioned alkylphenol polyoxyethylene ether used as a wetting agent comes from Rhodia Comp...

Embodiment 3）

[0034] The dosage form of the paddy field herbicide composition of the present embodiment is still wettable powder, and the rest of this wettable powder is the same as embodiment 2, and the difference is: the proportioning of each component described is: 16 parts by weight of carfentrazone-ethyl, 34 parts by weight of bisfluorin, 8 parts by weight of alkylphenol polyoxyethylene ether as a wetting agent, 5 parts by weight of sodium lignosulfonate as a dispersant, and 20 parts by weight of sodium lignosulfonate as a carrier light calcium carbonate and 17 parts by weight of white carbon black as a carrier.

[0035] The preparation method is the same as in Example 2.

Abstract

The invention discloses an herbicide composition in a paddy field. The herbicide composition consists of active ingredients, an aid and a carrier, wherein the active ingredients consist of carfentrazone-ethyl and bispyribac-sodium, wherein a weight ratio of the carfentrazone-ethyl to the bispyribac-sodium is 1:50 to 50:1; and the active ingredients are 5 to 90 percent of the total weight of the composition. The formulations of the composition can be wettable powder, water dispersible granules, dry suspending agents and microemulsion. The herbicide composition in the paddy field has the advantages of wide herbicidal spectrum, high herbicidal rate and the like, and has obvious synergism.

Description

technical field [0001] The invention relates to a herbicide, in particular to a rice field herbicide composition. Background technique [0002] Rice is the main food crop in my country. In recent years, the planting area of ​​rice has stabilized at about 420 million mu, so the demand for herbicides is very large. At present, there are many kinds of herbicides used in paddy fields. The most widely used herbicides in my country are bensulfuron-methyl, butachlor, quinclorac, molinate, metsulfuron-methyl and pyrazosulfuron-methyl. Among them, butachlor is about to be eliminated due to its high toxicity to fish and poor safety of post-emergence use. Other herbicides have also developed weed resistance due to their long-term promotion and use in rice fields. [0003] Mefentrazone-ethyl (also known as triafentrazone-ethyl, mefentrazone or mefentrazone, CAS No. 128621-72-7) is a triazolinone herbicide developed by FMC Corporation of the United States. Its chemical name is :( RS ...
