Description

Herbicidal composition containing triazosulfone and application thereof Technical field

The invention belongs to the field of pesticides, and in particular relates to a herbicidal composition containing triazosulfone and application thereof.

Background technique

Chemical weeding is the most economical and effective means of controlling weeds in farmland. However, long-term continuous high-dose use of single-species or single-acting chemical herbicides is prone to problems such as weed resistance and resistance evolution.

The chemical structural formula of triazosulfone is

It is a newly developed HPPD inhibitor herbicide for post-emergence stem and leaf treatment of rice fields. It has excellent biological activity and can effectively control a variety of malignant weeds in rice fields.

哒草特化学结构式

It is a selective post-emergence herbicide. After treatment, the stems and leaves are quickly absorbed by the leaves, hindering the Hill reaction of photosynthesis, causing the weed leaves to turn yellow and stop growing, and die to death. It is suitable for the control of broadleaf weeds such as wheat, rice, corn and other cereal crops, especially for swine fever, anti-branches and some underlying weeds.

The structural formula of the compound cyclopyrimorate (test code H-965) is

It is a pyridazine herbicide developed by Mitsui Chemicals Co., Ltd., and is a photosystem II inhibitor. Its creation may be based on the structure of pyridate and cedazine.

The compound amiodarone (BAY 314666, amicarbazone, CAS: 129909-90-6) is a triazolinone herbicide discovered by the Bayer Plant Protection Department in 1988. It is mainly used for controlling annual broadleaf weeds in corn fields and sugarcane fields. And part one Annual grass weeds.

The structural formula of the compound chlorofluoropyridyl ester is

It is the second aryl picolinate herbicide developed by Dow AgroSinciol following fluorochloropyridyl ester. Chlorhexidine ester is broad-spectrum, high-efficiency, fast-acting, low-dose, post-emergence stem and leaf treatment, used for multi-crop including rice, multi-regional control of grass weeds, broadleaf weeds and sedge.

In determining the ratio or content of A and active ingredient B, it should be measured from the characteristics and virulence of the two agents, and the main purpose of the formulation should be considered. On the basis of the preliminary pre-test, the A and B active ingredients used alone and mixed dosages are shown in the table. Water containing no drug, the same solvent and an emulsifier was used as a blank control.

2.2.2), repeated test
