Embodiment 1

[0030] Embodiment 1: A medicinal fertilizer granule for controlling weeds in paddy fields of the present invention is composed of penoxsulam, bensulfuron-methyl, fertilizer, slow-release agent, binder, coating agent, and filler materials. Based on the total weight of medicinal fertilizer granules, including: 0.01% to 10% of penoxsulam, 0.01% to 10% of bensulfuron-methyl, 10% to 60% of fertilizer, 0.1% to 2% of slow-release agent, and Agent 0.1% ~ 10%, coating agent 0.1 ~ 1%, the rest is filler.

[0031] Such as figure 1 As shown, according to a method for preparing medicinal fertilizer granules for controlling weeds in paddy fields of the present invention, 0.01% to 10% penoxsulam, 0.01% to 10% bensulfuron-methyl, and 10% to 60% fertilizer , 0.1%~2% sustained-release agent, 0.1%~10% binder, 0.1%~0.5% coating agent, and appropriate amount of filler are mixed evenly in a closed mixing tank, and then added to the granulation equipment for coating method Granules, dried at 80°C ...

Embodiment 2

[0033] Embodiment 2: In order to better verify the actual application effect of the present invention, the following examples are used to illustrate the efficacy test effect of the medicinal fertilizer granule of the present invention for controlling weeds in rice seedling throwing fields.

[0034] In July 2012, the present inventor used the present invention to prevent and control weeds in rice throwing fields in Laokeng Village, Renshan Town, Huidong County, Guangdong Province.

[0035] Test agents: (1) 0.03% penoxsulam·bensulfuron-methyl fertilizer granules.

[0036] Control agents: (2) 2.5% penoxsulam oil suspension concentrate, (3) 10% bensulfuron-methyl wettable powder, (4) manual weeding.

[0037] Control object: Weeds in rice throwing field.

Abstract

The invention discloses a medicinal fertilizer granule for controlling weeds in paddy fields and a preparation method thereof. The active ingredients of the herbicide fertilizer granule of the present invention are penoxsulam and bensulfuron-methyl, based on the total weight of the granule, wherein: 0.01% to 10% of penoxsulam and 0.01% to 10% of bensulfuron-methyl %, fertilizer 10%-60%, slow-release agent 0.1%-2%, binder 0.1%-10%, coating agent 0.1%-1%, and the rest are fillers. The above-mentioned materials are uniformly mixed in proportion, granulated by coating method, dried and sieved to obtain the medicinal fertilizer granule of the present invention. The medicinal fertilizer granule provided by the invention has both herbicide and fertilization effects in one application in rice production, and overcomes the practice of using herbicides and fertilizers twice or more under the prior art conditions.

Description

technical field [0001] The invention relates to a medicinal fertilizer granule for controlling weeds in paddy fields and a preparation method thereof. Background technique [0002] Penoxsulam, structural formula: [0003] [0004] English name: penoxsulam, chemical name: 2-(2,2-difluoroethoxy)-N-(5,8-dimethoxy(1,2,4)triazole-(1,5-C)pyrimidine- 2-yl)-6-trifluoromethyl-benzenesulfonamide, the mechanism of action: the drug is absorbed through the leaves, sheaths or roots of the weeds, and is transmitted to the meristems, causing the weeds to stop growing, yellow, and then die. It has good control effect on grass weeds, sedges and broadleaf grasses. [0005] Bensulfuron-methyl, structural formula: [0006] [0007] English name: bensulfuron-methyl, chemical name: α-{[(4,6-dimethoxypyrimidin-α-yl)aminocarbonylamino]sulfonylmethyl}benzoic acid methyl ester. Bensulfuron-methyl is a selective systemic herbicide, the active ingredient can diffuse rapidly in water, absorbed ...
