Problems solved by technology

As the bean belongs to Cyperaceae, it is sensitive to most herbicides, which limits the application of most herbicides in the bean field
Currently there is no registration and use of related herbicides in sedge crops
And most of its planting environment is sandy soil, which also limits the normal play of herbicide efficacy.
In addition, the conditions for the emergence of oily bean seedlings have higher temperature requirements. Generally, they are sown in the middle and late May. At this time, some weeds have already emerged, which increases the difficulty of weed control after sowing and pre-emergence soil treatment.

preparation example Construction

[0067] Second aspect, the present invention provides a kind of preparation method of Cyperaceae herbicidal suspoemulsion, comprising the following steps:

[0068] Prepare a suspoemulsion dosage form by preparing a formula amount of proturazine and propargylflurafen and refined metolachlor to prepare a suspoemulsion for herbicides of Cyperaceae crops;

[0069] The preparation method of the herbicidal suspoemulsion for Cyperaceae crops provided by the present invention is simple and convenient, and the formulation amount of promethazin, flurafen propargyl and refined metolachlor are mixed to form a suspoemulsion dosage form, so that proturazin, propargyl Flurafen and metolachlor are fully dispersed, and the prepared suspoemulsion for sedge crops has good stability.

[0070] Preferably, the particle size of the prometon and flufenazol is less than 45 μm;

[0071] Preferably, promethazin, flurafen propargyl are mixed with emulsifier and suspending agent to obtain a mixed solution...

Embodiment 1

[0090] A herbicidal suspoemulsion for sedge crops, comprising promezam, metolachlor-sperm and flurafen-propargyl, the ratio of proturazin, metolachlor-smart and flurachlor-propargyl is 30:30 :1.

Embodiment 2

[0092] A herbicidal suspoemulsion for Cyperaceae crops, the difference from Example 1 is that the ratio of promethazin, metolachlor-sperm, and flurafen-propynyl is 30:30:1.5.

Abstract

The invention provides a sedge crop herbicidal suspoemulsion and its preparation method, application and application method, which relate to the field of agricultural technology. The herbicidal suspoemulsion for Cyperaceae crops provided by the present invention includes prometon, metolachlor-sperm and flurafen propargyl, the three have different mechanisms of action on weeds, and the three can interact with each other after being mixed according to a specific ratio. Cooperate, promote each other, and enhance the hindering effect on the growth of weeds. It not only has a high control effect on the annual weeds that have been unearthed, but also has a high control effect on some weeds that have been unearthed when the pesticide is applied, and it is safe for oily bean. high sex. The preparation method of the herbicidal suspoemulsion for Cyperaceae crops provided by the invention is simple and convenient, the prepared herbicidal suspoemulsion for Cyperaceae crops has good stability, and can be used for weed control in Cyperaceae economical and medicinal crop fields.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a sedge crop herbicidal suspoemulsion and a preparation method, application and application method thereof. Background technique [0002] Oil sedge (Cyperusesulentus L.Var. Sativus) has another name called oil sedge. Angiosperm, Cyperaceae, Cyperus perennial herb. It is suitable for planting in well-ventilated sandy soil and sandy loam with high fertility. In terms of plant protection, weeds are more harmful to it. Weeds not only affect the emergence and tillering of the bean, but also affect the root development and tuber growth of the bean. As the bean belongs to Cyperaceae, it is sensitive to most herbicides, which limits the application of most herbicides in the bean field. At present, there is no registration and use of related herbicides in sedge crops. And most of its planting environment is sandy soil, which also limits the normal performance of herbicide effica...
