Use of herbicidal composition for preventing and treating germination or growth of unwanted plants in dry-land crops

Abstract

The invention relates to a use of an herbicidal composition containing flufenacet and clomazone for preventing and treating germination or growth of unwanted plants of Echinochloa crusgalli (L.) Beauv., Chenopodium album L., Xanthium sibiricum Patrin., Polygonum lapathifolium L., Amaranthus retroflexus L., Abutilon theophrasti Medic., and Commelina communis L. in crops of soybean, potato, cotton,corn, wheat and peanut, wherein a weight ratio of flufenacet to clomazone is 10:1-1:10, preferably 8:1-1:8, further preferably 5:1-1:5, more preferably 2.5:1-1:2.5.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to the use of a herbicidal composition containing flufenacet and clomazone in preventing unwanted plant germination or growth of dryland crops. Background technique [0002] Weeds in farmland can deteriorate the ecological environment of crops, reduce crop yield and quality, and affect the health of humans and animals. [0003] The current physical measures against weeds in farmland are: [0004] Crop rotation Different dryland crops have different associated weeds or parasitic weeds. These weeds have the same or similar living environment as the crops. Taking scientific crop rotation and changing crops will change the external ecological environment conditions in which weeds live. Reduce the damage of weeds. Deep plowing and land preparation The weed seeds scattered on the soil surface in the previous year are buried in the deep layer of the soil through deep plowing, so that they cann...

Problems solved by technology

However, with the continued use of many herbicide varieties on a large scale, many problems have arisen, such as the problem of weed resistance, especially the problem of resistance to older weeds is particularly prominent; Short validity period etc.
