Problems solved by technology

[0002] The common name of compound (A) is niscosulfuron (nicosulfuron, Chinese common name), and its chemical name is 2-(4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl)-N,N- Dimethylnicotinamide is a new type of herbicide that can be used to control monocot and dicotyledonous weeds in corn fields, but its herbicidal spectrum is limited. The control effect of iron amaranth, etc. is not very ideal
In addition, domestic and foreign patents have not mentioned its composition with other specific compounds
Therefore its effect in combination with other compounds is unpredictable

Embodiment 1

[0025] Embodiment 1 is a dosage form preparation example, and Embodiments 2-5 are biological embodiments.

[0026] Example 1:

[0027] a suspending agent

[0028] Mix 2% of active component A (purity ≤ 90%) and 20% of active component B (purity 81%) with 5% of 0201B as emulsifier, 5% of JFC as wetting agent, and 5% of JFC as dispersant 3% pull-off powder and 3% n-butanol as a defoamer are mixed sequentially and ground in a colloid mill until the particle size is below 5 microns.

[0029] b wettable powder:

[0030] 40 parts of weight of effective composition and 2 parts of weight of sodium dodecylbenzenesulfonate as wetting agent, 5 parts of raw sodium lignosulfonate as dispersant and 53 parts of weight of kaolin in the air flow It is made by ultrafine pulverization in a pulverizer.

[0031] c powder

[0032] It is prepared by mixing 10 parts by weight of the effective composition and 90 parts by weight of talcum powder as an inert substance, and pulverizing them uniforml...

Embodiment 2

[0036] Location: Xinyi, Jiangsu Sowing: June 15, 2001

[0037]

[0038] Conclusion: The combined control effect of nicosulfuron and 2,4-D-butyl ester is higher than the expected theoretical control effect, which proves that the mixed use of nicosulfuron-methyl and 2,4-D-butyl ester has a synergistic effect. Example 3: The control effect of nicosulfuron and metrizone on weeds in cornfields (%)

Embodiment 3

[0039] Location: Xinyi, Jiangsu Sowing: June 15, 2001

[0040]

[0041] Conclusion: The combined control effect of nicosulfuron and metrizone is higher than the expected theoretical control effect, which proves that the mixed use of nicosulfuron and metrizone has a synergistic effect. Embodiment 4: The control effect (%) of nicosulfuron and sulcotrione mixed to cornfield weeds

Abstract

An improved herbicide composition is one kind of mixture comprising 2-(4,6-dimethoxy pyrimidyl-2-aminoformamidosulfonyl)-N,N-dimethyl nicotinamide and at least one of 1,4-D butylate, metribuzin, sulcotrione and atrazine. It has high herbicidal effect to crab grass, green bristle grass, goose grass, etc. in corn field, and its herbicidal effect is higher than that of its single component.

Description

technical field [0001] The present invention relates to herbicidal compositions having improved properties. Wherein the compound (A) represented by the effective component formula (1) and at least one specific other herbicidal composition (B) Background technique [0002] The common name of compound (A) is niscosulfuron (nicosulfuron, Chinese common name), and its chemical name is 2-(4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl)-N,N- Dimethylnicotinamide is a new type of herbicide that can be used to control monocot and dicotyledonous weeds in corn fields, but its herbicidal spectrum is limited. The control effect of iron amaranth is not very ideal. In addition, domestic and foreign patents have not mentioned its composition with other specific compounds. Therefore its effect in combination with other compounds is unpredictable. Contents of the invention [0003] The purpose of the present invention is to find out that the efficacy or activity level of the herbicida...
