Abstract

The invention provides a herbicide composition. Active ingredients in the composition comprise an active ingredient A dicamba and an active ingredient B in a weight ratio of (1:40)-(40:1), wherein the active ingredient B is any one of procarbazone and diuron. 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 improves the pesticide effect, delays generation of weed resistance, has low residues, is safe to afterreap crops, has higher control effects on broad leaf weeds and grassy weeds, and can control harms of various weeds in wheat fields and cornfields through using the herbicide composition once.

Description

technical field [0001] The invention relates to the field of pesticide preparations, and more specifically relates to a herbicidal composition containing dicamba, which is used for controlling field broad-leaved weeds and gramineous weeds. Background technique [0002] 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. 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 herbicide products has become a research hotspot. In order to meet this requirement, the selection of compound mixtures of pesticides has become the current preferred effective way. The purpose of the present...
