Abstract

The invention belongs to the field of agricultural herbicide, and in particular relates to a compound herbicide. The compound herbicide contains diflufenican and oxyfluorfen which serve as active ingredients and a weight ratio of the diflufenican and oxyfluorfen is (10:1)-(1:10). The compound herbicide has the advantages that: 1, the synergistic effect is obvious, and the pesticide effect is greatly improved; 2, the pesticide effect is improved, the field consumption of the active ingredients is reduced, the production and use costs are reduced, and pesticide residue and environmental pollution are reduced; and 3, the compound herbicide consists of the active ingredients with different action mechanisms, the action sites are increased, pesticide resistance of weeds are overcome and delayed, and the compound herbicide is an important means for comprehensively preventing and controlling field weeds.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, in particular to a compound herbicide. Background technique [0002] Diflufenican belongs to carotenoid biosynthesis inhibitors and is a broad-spectrum selective wheat field herbicide, which causes chlorophyll damage, cell rupture, and plant death. Apply 125-250g / ha pre-emergence or post-emergence to wheat and barley fields in autumn to control gramineous and broad-leaved weeds, especially weeds such as pig's weeds, porcini and viola. The agent has the following characteristics: wide herbicide spectrum; can control malignant weeds; long efficacy period in soil; stable efficacy; can be mixed with other herbicides. After the pesticide is applied, a leaching-resistant medicinal soil layer will be formed on the soil surface, and it will remain alive throughout the crop growth period. When the weeds germinate through this medicinal soil layer, they will contact and absorb the medicinal agent. I...
