Embodiment 1

[0030] Example 1 ： The medicinal fertilizer granule for preventing and controlling weeds in paddy fields of the invention is composed of penoxsulam, bensulfuron-methyl, fertilizer, slow-release agent, binder, coating agent and filler raw 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, dri...

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 pesticide-and-fertilizer granules for preventing and killing weeds in paddy fields and a preparation method thereof. The pesticide-and-fertilizer granules for killing the weeds comprise the following components in percentage by weight: 0.01-10% of penoxsulam and 0.01-10% of bensulfuron-methyl which are used as active ingredients, 10-60% of a fertilizer (or fertilizers), 0.1-2% of a slow-release preparation, 0.1-10% of a binder (or binders), 0.1-1% of a membrane forming agent (or membrane forming agents) and the balance of a filler (or fillers). The preparation method comprises the following steps of: uniformly mixing the components in ratio; granulating by using a membrane forming method; drying; and screening to prepare the pesticide-and-fertilizer granules. The pesticide-and-fertilizer granules are applied only once during the rice production and have the effects of killing the weeds and fertilizing at the same time, so that the defect that two or more steps are required for applying the herbicide and the fertilizer (s) in the prior art is overcome.

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 ...
