As the oily bean belongs to Cyperaceae, it is sensitive to most herbicides, which limits the application of most herbicides in the oily bean
[0003] In addition, as of August 23, 2020, there were 11,082 herbicides registered in my country, which were used in most of the crops cultivated in my country. Among them, after inquiry, no research and development and use of herbicide varieties in Yousha bean fields have been found

[0137] According to one aspect of the present invention, a kind of preparation method of above-mentioned herbicide, described preparation method comprises the following steps:
[0138] The herbicide is obtained by shearing, preparing and mixing the components.
[0139] The preparation method of the herbicide provided by the invention comprises the steps of uniformly mixing each component to prepare the herbicide. The above preparation method has the advantages of simple preparation method and easy operation.
[0140] According to one aspect of the present invention, the application of a kind of above-mentioned herbicide in bean field, broomcorn millet field and millet field.
[0141] The above-mentioned herbicide provided by the present invention can be widely used in the planting of bean fields, millet fields and millet fields.
[0142] In a preferred embodiment of the present invention, the application method of the herbicide is 5-10 cm behind the seedlings of the oleracea ...
Embodiment 1
[0146] A herbicide comprising the following components:
[0147] 18 parts of atrazine, 6 parts of isooctyl fluroxypyr, 17 parts of emulsifier, 0.7 parts of dispersant, 1.5 parts of spreading agent, 2 parts of suspending agent, 0.4 part of spreading agent, 0.4 part of leaf affinity agent, Make up to 100 parts with water;
[0148] The preparation method of described herbicide comprises the following steps:
[0149]First add the measured atrazine and appropriate amount of water into a sand mill for sand milling. After the original powder particles of the original drug are less than 45um, open the discharge valve and enter the shear mixer, add some additives for stirring, and On the one hand, put isooctyl fluroxypyr and the corresponding additives into another shearing mixer for full shearing and stirring. After the properties are stable, put the two into the same shearing mixer, and make up other Auxiliaries (emulsifier, dispersant, spreading agent, suspending agent, spreading ...
Embodiment 2
[0151] A herbicide comprising the following components:
[0152] 48 parts of atrazine, 7 parts of isooctyl fluroxypyr, 17-21 parts of emulsifier, 0.7 part of dispersant, 1.5 parts of spreading agent, 4 parts of suspending agent, 0.6 part of developing agent, 0.6 part of leaf affinity agent parts, make up to 100 parts with water;
[0153] The preparation method of the present embodiment herbicide is the same as embodiment 1.

Abstract
The invention provides a cyperus esculentus field stem and leaf treatment herbicide and a preparation method and application thereof, and relates to the technical field of agricultural planting. The cyperus esculentus field stem and leaf treatment herbicide comprises fluroxypyr-mepthyl and atrazine, and the mass ratio of fluroxypyr-mepthyl to atrazine is 1: (3-8), wherein the fluroxypyr-mepthyl isan systemic conduction type post-emergence herbicide; atrazine is systemic selective pre-emergence and post-emergence herbicides; the fluroxypyr-mepthyl and the atrazine are large in active mechanismdifference, after the fluroxypyr-mepthyl and the atrazine are applied in a combined mode according to the mass ratio, a remarkable synergistic effect on weed removal is achieved, and weeds are not prone to generating stress resistance; in addition, a weed leaf affinity agent is also added in processing or use of the herbicide, so that the prevention and control effect on weeds can also be improved. Meanwhile, atrazine and fluroxypyr in the herbicidal composition are compounded, so that the herbicidal composition has relatively high safety to broom corn millet and millet, and can be used for preventing and controlling broadleaf weeds in broom corn millet and millet fields.
Description
technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a herbicide for treating stems and leaves in oil sedge bean fields and its preparation method and application. Background technique [0002] Yassa bean has been cultivated in a large area in my country since its introduction to 2006. Scientific researchers have conducted extensive and in-depth explorations on its breeding, cultivation technology, harvesting machinery, and even product processing, and have achieved gratifying scientific research results. Yassa bean is resistant to drought, barrenness and high economic output ratio. The planting area has increased year by year. In the adjustment of agricultural planting industry structure, the selectivity of crop rotation has been increased. In terms of plant protection, the oily bean has the characteristics of resistance to diseases and insects, but weeds are the most harmful to it, which has become the main and urge...
