Problems solved by technology

When a herbicide with a single active ingredient is used in agricultural production, it cannot completely and effectively control the occurrence of weeds in wheat fields due to factors such as herbicidal range, herbicidal ability, and resistance, and the efficacy of weed eradication will be greatly reduced. Some herbicides are likely to cause residual toxicity to current crops or subsequent crops due to their high water solubility, short field duration, excessive dosage, or uneven application.

Embodiment 1、75

[0027] (Example 1, 75% water dispersible granules)

[0028] 75% monopyrimsulfonate·isoproturon water dispersible granules: monopyrimsulfonate 1.1%, isoproturon 73.9%, D-425 (naphthalene sulfonate dispersant) 5%, K12 sodium lauryl sulfate 2.5% %, sodium bentonite 2%, kaolin to make up to 100%, (the above contents are all mass percentage contents, the same below).

[0029] Prepare water dispersible granules with a mass percentage of 75% according to the conventional preparation method: after all the weighed materials are mixed uniformly, pulverized by a jet mill, mixed uniformly again, and then a certain amount of water is added to knead the mixture , extrusion granulation, drying and sieving to obtain water dispersible granules.

Embodiment 2、40

[0030] (Example 2, 40% dispersible oil)

[0031] 40% monopyrimsulfonate·isoproturon dispersible oil: monopyrimsulfonate 0.59%, isoproturon 39.41%, alkylbenzene polyoxyethylene ether 4%, phosphate ester 4%, dodecylbenzenesulfonic acid Calcium 8%, organic bentonite 0.5%, methyl oleate supplemented to 100%, and prepared into a dispersible oil agent with a mass percentage of 40% according to a conventional preparation method.

Embodiment 3、50

[0032] (Example 3, 50% suspending agent)

[0033] 50% monopyrimsulfonate·isoproturon suspending agent: monopyrimsulfonate 0.74%, isoproturon 49.26%, sodium methylnaphthalene sulfonate formaldehyde condensate 6%, octylphenol polyoxyethylene ether 3%, silicic acid 0.5% magnesium aluminum, 5% propylene glycol, 0.1% xanthan gum, 0.2% sodium benzoate, 0.2% silicone oil, add water to make up to 100%, and prepare a suspension agent with a mass percentage of 50% according to a conventional preparation method.

Abstract

The invention discloses a compound herbicidal composition containing monopyrimsulfonate and its application. The active ingredients are monopyrimsulfonate and isoproturon. The binary herbicidal composition of the present invention is compounded by using monosulfanilate and isoproturon with different herbicidal spectrums and complementary advantages and disadvantages. The combined use of the two delays the generation of drug resistance of crops and has ideal application effects: killing It has the advantages of wide grass spectrum, quick effect, high efficiency, low toxicity, low residue, safety and environmental protection, which can reduce the dosage of pesticides, reduce pesticide residues, good environmental compatibility, and safety for humans and animals. It is a high-quality chemical herbicide for wheat crops. As the content of active ingredients is reduced, the pesticide residues are reduced on the premise of improving the efficacy of the pesticide, and the safety of wheat and subsequent crops is higher, and the possibility of residual poisoning of pesticides to humans and animals is avoided.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a compound herbicidal composition containing a monopyrimsulfonate and its application. Background technique [0002] Wheat is one of the main crops in my country. With the continuous expansion of wheat planting area, the weed damage in wheat fields is also becoming more and more serious. Whether it can effectively control the weed damage in wheat fields and stabilize the high yield of wheat has become one of the main topics of modern agricultural herbicide research. . [0003] At present, most of the wheat field herbicides on the market have the problem that the herbicidal spectrum is narrow and cannot be effective in the field of broadleaf weeds and grass weeds at the same time. [0004] Monosulfuron ester (code #NK94827) is a sulfonylurea herbicide developed by the National Engineering Research Center of Pesticide (Nankai University) after the industrialization of monosulfuron (#NK92...
