Example Embodiment

[0030] Example 1

[0031] S1, take by weighing 70kg calcium dodecyl benzene sulfonate, 40kg tristyryl phenol polyoxyethylene ether and 20kg alkylphenol polyoxyethylene ether and mix uniformly in advance as emulsifying aid, drop emulsifying aid into 500kg methyl oleate Mix evenly in the ester;

[0032] S2, then add 5kg pine needle soil, 10kg calcium sugar alcoholate and 3kg bentonite, stir and mix, then add 270kg mesotrione to shear for 30min, and the shearing speed is 3000r / min;

[0033] S3. The sheared material is ground by a sand mill, and after grinding for 30 minutes, it is put into a mixing kettle and stirred evenly to obtain a dispersible oil suspension agent.

Abstract

The invention relates to the field of herbicides, and particularly discloses a dispersible oil suspending agent and a preparation method thereof. The dispersible oil suspending agent comprises 270-330 parts of an active compound, 130-190 parts of an emulsifying aid, 500-570 parts of a dispersion medium, 3-7 parts of a suspension stabilizer and 15-35 parts of an adsorption stabilizer, the active compound comprises mesotrione, the adsorption stabilizer comprises pine needle mulch and sugar alcohol calcium, and the weight ratio of the pine needle mulch to the sugar alcohol calcium is (1-3): (2-4); the preparation method comprises the following steps: sequentially adding the emulsifying aid, the suspension stabilizer, the atrazine, the mesotrione, the nicosulfuron, the pine needle mulch and the sugar alcohol calcium into the dispersion medium, shearing, grinding and uniformly stirring to obtain the dispersible oil suspending agent. The dispersible oil suspending agent can be used for alkaline soil weeding, the mobility of mesotrione in alkaline soil is reduced, mesotrione entering underground water is reduced, and then the adverse effect on the weeding effect is reduced.

Description

technical field [0001] The present application relates to the field of herbicides, more particularly, it relates to a dispersible oil suspension and a preparation method thereof. Background technique [0002] Dispersible oil suspension agent refers to one or more active ingredients of pesticides (at least one of which is a solid original drug) in a non-aqueous dispersion medium, with the help of some additives, through sand mill grinding, the original drug is uniformly distributed. Disperse in the oil phase to form a highly dispersed, highly suspended, flowable and stable liquid-solid system. [0003] Nicosulfuron-methyl, mesotrione and atrazine are all insoluble technical substances, which can be used for herbicides by making dispersible oil suspensions. [0004] Aiming at the above-mentioned related art, the inventor believes that: because mesotrione belongs to the soil that is difficult to adsorb pesticides and has strong water solubility, when mesotrione is used in alka...
