preparation example Construction
[0067] Second aspect, the present invention provides a kind of preparation method of Cyperaceae herbicidal suspoemulsion, comprising the following steps:
[0068] Prepare a suspoemulsion dosage form by preparing a formula amount of proturazine and propargylflurafen and refined metolachlor to prepare a suspoemulsion for herbicides of Cyperaceae crops;
[0069] The preparation method of the herbicidal suspoemulsion for Cyperaceae crops provided by the present invention is simple and convenient, and the formulation amount of promethazin, flurafen propargyl and refined metolachlor are mixed to form a suspoemulsion dosage form, so that proturazin, propargyl Flurafen and metolachlor are fully dispersed, and the prepared suspoemulsion for sedge crops has good stability.
[0070] Preferably, the particle size of the prometon and flufenazol is less than 45 μm;
[0071] Preferably, promethazin, flurafen propargyl are mixed with emulsifier and suspending agent to obtain a mixed solution...
Embodiment 1
[0090] A herbicidal suspoemulsion for sedge crops, comprising promezam, metolachlor-sperm and flurafen-propargyl, the ratio of proturazin, metolachlor-smart and flurachlor-propargyl is 30:30 :1.
Embodiment 2
[0092] A herbicidal suspoemulsion for Cyperaceae crops, the difference from Example 1 is that the ratio of promethazin, metolachlor-sperm, and flurafen-propynyl is 30:30:1.5.
