Example Embodiment

[0126] Example 1 10% sulforaphane sulfide + 10% flurochlorid wettable powder

[0127] The formula is composed of 10% pyrethrum sulfide, 10% flurochloridone, 8% sodium salt of naphthalenesulfonic acid formaldehyde condensate, 6% alkylphenol polyoxyethylene ether phosphate, and the balance of kaolin;

[0128] The preparation method is as follows: weigh the above-mentioned components in the formula amount, and mix, grind and pulverize them to prepare a wettable powder.

Example Embodiment

[0129] Example 2 1% sulforaphane sulfide + 50% flurochlorid wettable powder

[0130] The formula is composed of: pyrifenpyrsulfide 1%, flurochloridone 50%, fatty alcohol polyoxyethylene ether sodium sulfate 8%, trisiloxane polyoxyethylene ether 8%, and the balance of bentonite;

[0131] The preparation method is as follows: weigh the above-mentioned components in the formula amount, and mix, grind and pulverize them to prepare a wettable powder.

Example Embodiment

[0132] Example 3 5% sulforaphane sulfide + 25% flurochloridone water emulsion

[0133] The formula is composed of: pyrimidine sulfide 5%, flurochloridone 25%, N-methylpyrrolidone 20%, phenethylphenol polyoxyethylene polyoxypropylene ether 5%, ethylene glycol 5%, propylene glycol 5%, Water margin

[0134] The preparation method is as follows: adding pyrimfen sulfide, flurochloridone, solvent, emulsifier and the like together to dissolve into a uniform oil phase; mixing antifreeze, antifoaming agent, water, etc. together to form a uniform water phase. Under high-speed stirring, add the oil phase to the water phase to prepare a water emulsion.

Description

technical field [0001] The present invention relates to the field of agriculture, in particular to a herbicidal composition; it also relates to the use of the herbicidal composition to control unwanted plant germination or growth. Background technique [0002] The use of chemical herbicides is one of the important symbols of modern agriculture. In recent years, the sales of herbicides have increased year by year, and the application area has also expanded year by year. However, with the continued use of many herbicide varieties on a large scale, many problems have arisen, such as the problem of weed resistance, especially the problem of resistance to older weeds is particularly prominent; Short validity and so on. Therefore, there is an urgent need for long-acting herbicides with a wide range of weed control, strong selectivity and less pressure on weed resistance, and combinations thereof. Contents of the invention [0003] The object of the present invention is to prov...
