Abstract

The invention discloses an oil-suspension agricultural mesotrione preparation as well as a preparation method and applications thereof. The oil-suspension agricultural mesotrione preparation is prepared from the following components in parts by weight: 3-22 parts of mesotrione, 10-20 parts of emulsifier, 3-8 parts of thickener and 50-80 parts of oil solvent. The components of the mesotrione, the emulsifier, the thickener and the oil solvent, which are provided by the invention, are scientifically and reasonably proportioned, a plurality of surface active agents are filtered and compounded to select an optimal emulsifier for preparing oil-suspension agricultural mesotrione preparation, the prepared preparation has the properties all according with the requirements on an oil-suspension preparation, and particularly, the active constituent mesotrione has greatly improved structural stability and obviously decreased resolution ratio, can be stored for a long time and is convenient to use. The preparation method of the oil-suspension agricultural mesotrione preparation, which is provided by the invention, has strong operability and high production efficiency and can realize industrialized mass production.

Description

technical field [0001] The invention relates to an agricultural preparation, in particular to a mesotrione oil suspension agricultural preparation, a preparation method and an application thereof. Background technique [0002] Mesotrione is a new triketone, as a herbicide for pre-emergence soil treatment, it is suitable for weed control in plowing, inter-sowing, and fern cornfields, and can effectively control a variety of annual broad-leaved weeds and Grass weeds have low toxicity and are environmentally friendly herbicides. [0003] The planting methods and planting habits of corn in my country are various, especially in the summer corn planting area of ​​North China, the planting mode of wheat field interplanting and iron stubble sowing corn is very common. Weeding habits are also changing. In the North China Plain area, the degree of mechanized harvesting of wheat is very high. Due to the high stubble and straw left in the wheat fields harvested by machines, the effect ...
