Abstract

The invention provides a herbicide composition. Active ingredients in the composition comprise dicamba and clodinafop-propargyl in a ratio of (1:1)-(40:1). The herbicide composition can be prepared into wettable powder and water-dispersible granules according to the known methods. The herbicide composition has the following advantages: relative to the single agent, on the premise of expanding the weed-controlling spectrum, the herbicide composition delays generation of weed resistance, improves the pesticide effect, has low residues, is safe to wheat and afterreap crops and can control most monocotyledon and dicotyledon weeds in wheat fields once. The invention also provides application of the herbicide composition in controlling weeds in the wheat fields.

Description

technical field [0001] The invention relates to the field of pesticide preparations, and more specifically relates to a herbicidal composition containing dicamba and clodinafop-propargyl, which is used for controlling broad-leaved weeds and gramineous weeds in wheat fields. Background technique [0002] Wheat is the main food crop in our country, and it is reported that the wheat in the whole country suffers from weeds to varying degrees every year. In order to reduce the economic losses caused by weeds and reduce labor intensity, and because of the convenience, quick effect and long control time of chemical weeding, herbicides have gradually been accepted by people. In recent years, with the increase of herbicide varieties and the widespread promotion of chemical control technology in agricultural production, herbicides have been widely used in various stages of crop growth. At present, the development of high-efficiency, low-toxicity, low-residue and non-polluting herbici...
