Embodiment 1～20

[0099] Embodiment 1~20 wettable powder

[0100] Mix ciprosulfuron-methyl, active ingredient B, dispersant, wetting agent and filler in a mixing tank evenly, pulverize with a jet mill and then mix evenly to make ciprosulfuron-methyl-active ingredient B wettability For powder products, the active ingredient B includes one of fluroxypyr, sodium 2-methyl-4-chloride, acifluorfen, isoproturon, bromoxynil and their salts. The specific formula is shown in Table 7.

[0102]

[0103]

[0104] The new preparation can be prepared by exchanging fluroxyrpyr, sodium 2-methyl-4-chloride, acifluorfen, isoproturon, bromoxynil and their salts in the table.

Embodiment 21～32

[0105] Embodiment 21~32 water dispersible granules

[0106] Cyprosulfuron-methyl, active ingredient B, dispersant, wetting agent, disintegrant, filler, etc. are air-pulverized together to obtain the required particle size, and then other additives such as binder are added to obtain granulation materials. Quantitatively send the material into the fluidized bed granulation dryer, and after granulation and drying, the ciprosulfuron-methyl-active ingredient B water-dispersible granule product is obtained. The active ingredient B includes fluroxypyr, 2-formazol One of 4 sodium chloride, fluorfen, isoproturon, bromoxynil and their salts. See Table 8 for details.

Abstract

The invention relates to a weeding composition containing cyclosulfamuron. The weeding composition is mainly characterized by comprising 1-60% of an active ingredient A cyclosulfamuron and 1-80% of an active ingredient B, wherein the active ingredient B is selected from any of the following components: fluroxypyr, MCPA-Na, fluoroglycofen-ethyl, isoproturon, bromoxynil and salt. The weeding composition can be prepared into a wettable powder, a water dispersible granule, an oil suspended agent, a suspoemulsion, a microemulsion and an emulsion in water. The weeding composition can be used for preventing and treating wheat, corn and rice.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing cyprosulfuron-methyl, which is used for preventing and controlling field weeds. Background technique [0002] In recent years, the direction of pesticide development is to embody high efficiency, low toxicity, low residue and no pollution. The specific performance is the pursuit of "three highs", that is, (1) high safety, which not only requires low toxicity, low residue, and pollution-free; (2) high biological activity; (3) high selectivity. Therefore, continue to improve the performance of the current pesticide products to meet the requirements of high efficiency, low toxicity and no pollution. Therefore, choosing a compound mixture of pesticides has become the current first choice and an effective way. By adjusting the ratio of different pesticides, the best synergistic effect can be obtained from the pesticides with compleme...
