[0002] At present, the main herbicides in rice fields are ethylbenzyl, butylbenzyl and dichlorobenzyl. Due to long-term use, more and more resistant weeds have caused a large reduction in crop yield.
Chinese patent CN102334486A discloses a composite herbicide comprising 5% to 60% of oxadiazone, 3% to 50% of oxyfluorfen, 5% to 70% of butachlor, 1% to 20% of Adjuvant and 5% to 80% solvent or carrier, this herbicide is suitable for both paddy fields and cotton fields, but its application amount is relatively large, and its control effect on weeds is not ideal

Abstract
The invention provides a pesticide composition. The pesticide composition is composed of butachlor, oxadiazon and oxyfluorfen, wherein the mass ratio of the butachlor to the oxadiazon to the oxyfluorfen is (6-25) to (1-5) to (6-20). The invention further provides a pesticide preparation. The invention further provides application of the pesticide composition provided by the technical scheme or the pesticide composition provided by the technical scheme to prevention and removal of weeds in a paddy field. According to the pesticide composition, when the butachlor, the oxadiazon and the oxyfluorfen are compounded and the mass ratio is controlled to be (6-25) to (1-5) to (6-20), the butachlor, the oxadiazon and the oxyfluorfen act with each other; and the pesticide composition has a high preventing and removing effect on the weeds under the condition that the application amount is greatly reduced, and particularly has good preventing and removing effect on the weeds in the paddy field, such as barnyard grass, monochoria vaginalis or cyperus difformis.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition, its formulation and its application.
