Problems solved by technology

[0003] Oil suspensions usually require that the solubility of the original drug in the oil should be less than 500mg / l, and the increase in solubility will easily cause Austenitic ripening, which will cause oil separation, precipitation and agglomeration at the bottom, which will affect the quality of the preparation
At present, the oil suspensions containing atrazine on the market, because the solubility of atrazine in conventional oil suspension solvents (such as methyl oleate, vegetable oil) is usually greater than 2000mg / l, it will cause Oswald ripening when placed for a long time, and there will be separation. Serious quality problems such as layering, oil separation, agglomeration, and degradation of the original drug, and it is difficult for farmers to dilute and spray during use, the control effect is greatly reduced, and frequent occurrence of phytotoxicity due to unevenness greatly limits this type of weeding The development of oil suspension concentrate

Embodiment 1

[0029] This example provides an oil suspension, its raw material formula is: Nicosulfuron 3%, Mesotrione 7%, Atrazine 20%, Fatty alcohol polyvinyl ether 10%, EO / PO block copolymer 5% %, calcium dodecylbenzenesulfonate 5%, sodium alkylnaphthalene sulfonate 3%, white carbon black 1%, mineral spirits (n-dodecylbenzene) make up 100%.

[0030] Mix all the raw materials evenly in proportion, and then go through a sand mill for ultrafine sand grinding, control the particle size at 3 μm, once for 60 minutes, and repeat twice.

Abstract

The invention relates to an oil suspended agent prepared from an agricultural chemical active ingredient and solvent oil, wherein the agricultural chemical active ingredient is a combination of one or more of sulfonylurea compounds, triketone compounds and triazine compounds; the solvent oil contains compounds as shown in a general formula (I) R-(CH2)n-R minute (I); in the formula (I), R is alkyl with 5 to 10 carbon atoms, n is an integer of 6 to 20, and R minute is phenyl, benzyl or naphthyl. The oil suspended agent is good in medicinal effect and has no biosecurity perplexity; in addition, after the oil suspended agent is placed for a long time, less oil is separated out, and no bottom precipitation phenomenon is caused; the product is stable in quality, the problem of poor stability in the storage process of the product is solved, and the use of farmers is facilitated.

Description

technical field [0001] The invention belongs to the field of plant protection preparations, in particular to an oil suspension. Background technique [0002] Oil suspension (oil suspension) is a pesticide preparation with vegetable oil, mineral oil or other synthetic oils as the carrier. It has strong conductivity, good adhesion, long residence time, resistance to rain erosion, and high utilization of active ingredients. Advantages, showing higher efficacy and duration. Oil suspension concentrate is an efficient and economical green pesticide dosage form, especially in herbicides, which has a large market space. [0003] Oil suspensions usually require that the solubility of the original drug in the oil should be less than 500mg / l. The increase in solubility will easily cause Austenitic ripening, resulting in oil separation, and precipitation and agglomeration at the bottom, which will affect the quality of the preparation. At present, the oil suspensions containing atrazi...
