Abstract

The invention belongs to the field of agricultural herbicides containing heterocyclic compounds and particularly relates to a herbicide containing mesotrione and clopyralid. The content by weight of the active ingredient mesotrione is 1 part, the content by weight of the clopyralid is 0.1 part-10 parts, and the content by weight of the clopyralid is 1 part-2 parts. The herbicide disclosed by the invention has obvious synergy and can greatly improve the efficacy; the efficacy is improved, the production cost and the using cost are reduced, and pesticide residue and environmental pollution can be reduced; and the complex composition comprises the active ingredients with different action mechanisms, can increase action sites and is conductive to overcoming and deferring the production of pesticide resistance of weeds.

Description

Technical field [0001] The invention belongs to the field of agricultural herbicides containing heterocyclic compounds, and particularly relates to a herbicide containing mesotrione and clopyralid. Background technique [0002] The application of chemical weed control is the most effective method for the control of weeds in farmland, but long-term continuous high-dose use of a single chemical herbicide is likely to cause problems such as herbicide residues, environmental pollution, and the development of weed resistance and resistance. The development of new varieties and reasonable mixing is an effective way to solve the above-mentioned problems. However, with the continuous increase in the price of developing new varieties of herbicides, the development of compound agents with low investment and short development period has been increasingly popular with domestic and foreign researchers. Pay attention. [0003] Mesotrione is a triketone compound, also known as "Mesotrione", ...
