Cyperaceae crop weeding suspoemulsion as well as preparation method, application and application method thereof

Abstract

The invention provides cyperaceae crop weeding suspoemulsion as well as a preparation method, application and an application method thereof, which relate to the technical field of agriculture. The cyperaceae crop weeding suspoemulsion provided by the invention comprises prometryn, s-metolachlor and flumioxazin, the action mechanisms of prometryn, s-metolachlor and flumioxazin on weeds are different, prometryn, s-metolachlor and flumioxazin can be mutually matched and promoted after being mixed according to a specific proportion, and the hindering effect on weed growth is enhanced. Thesuspoemulsion not only has a relatively high control effect onannual weeds unearthed, but also has a relatively high control effect on part of weeds which are unearthed during pesticide application, and is high in safety to cyperus esculentus. The preparation method of the cyperaceae crop weeding suspoemulsion is simple and convenient, and the prepared cyperaceae crop weeding suspoemulsion is good in stability and can be used for weed control of cyperaceae economic 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...

AI Technical Summary

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.
