Embodiment Construction

[0011] One, the processing steps of preparing the fenpyramid compound herbicide of the present invention:

[0012] 1. Weighing: Weigh 3-8kg of fenpyramid, 1kg of bensulfuron-methyl, 1.5kg of auxiliary agent NN0 (sodium benzenesulfonic acid formaldehyde condensate), and 1.5 kg of BX (sodium butylnaphthalenesulfonate) , Kaolin 38 ~ 43kg.

[0013] 2. After stirring and mixing the above raw materials, they are crushed by air flow, then stirred and mixed, and packed separately.

[0014] Two, the example of application of the fenpyramid compound herbicide of the present invention:

[0015] The field test of fenpyramid compound herbicide was carried out at the Wantou Base of the Institute of Agricultural Sciences in Lixiahe District, Jiangsu Province. Weeds include barnyardgrass, daughter, three-edge grass, Moshang vegetables, festival vegetables, bermudagrass, clove Polygonum and so on. The rice was sown on June 5, 2009, and the rice variety was Yangfujing 8. Apply pesticides 18...

Abstract

The invention which provides a metamifop compound herbicide relates to the technical field of agricultural production, and specially relates to the technical field of paddy field compound herbicide production. Metamifop and bensulfuron methyl are treated as effective components with a mass ratio of 3 to 8:1. The metamifop compound herbicide, which is prepared through conventional methods and is a novel, high efficient and special herbicide for the paddy field, allows various weeds to be controlled once and effectively, can be used in paddy direct-seeding fields, dry direct-seeding fields, seedling fields, transplantation fields, throwing-transplanted fields or machine-transplanted fields, and has special efficacy on weeds such as barnyard grass, Chinese sprangletop, digitaria sanguinalis and the like which are difficult to control in the direct-seeding fields. The herbicide allows paddy to be safe, usage to be convenient, labor and time to be saved and production and income to be increased.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to the technical field of compound herbicide production in paddy fields. Background technique [0002] Old products such as quinclorac have low control effects on barnyardgrass in paddy fields, and there is no excellent barnyard killer at present. In addition, when using quinclorac, factors such as weather, temperature, seedling quality and improper use are prone to phytotoxicity. [0003] Ding-benzyl herbicides have high activity, good safety, and low cost, and are the leading herbicides in the southern seedling throwing field. However, the control effect of this type of herbicide on barnyard grass is slightly poor, and the control effect is only 65%~ 76%. Therefore, there are almost no herbicides on the market that can kill both weeds and barnyardgrass. [0004] Metamifop (Metamifop) is an aryloxyphenoxypropionate herbicide developed by Korea Chemical Technology...
