Technical Field
The invention belongs to the field of pesticides, and particularly relates to a weeding composition containing N- (1,3, 4-oxadiazole-2-yl) arylformamide racemes and application thereof.
Background
Chemical weeding is the most economic and effective means in preventing and removing weeds in farmlands, but the problems of drug resistance and resistance evolution of weeds and the like are easily caused by using a single variety or a single action mode of chemical herbicide continuously at a high dose for a long time. The reasonable compounding or mixing of the herbicide compound has the advantages of expanding the weed spectrum, improving the control effect, delaying the occurrence and development of drug resistance and drug resistance of weeds and the like, and is one of the most effective methods for solving the problems. For example, patent CN103596946A discloses N- (1,3, 4-oxadiazole-2-yl) arylformamide and its use as herbicide, and there is still a need to develop a variety of herbicidal compositions with high safety, broad herbicidal spectrum, synergistic effect and capability of solving the problem of resistant weeds.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides a weeding composition containing an N- (1,3, 4-oxadiazole-2-yl) arylformamide racemate and application thereof. The composition can effectively prevent and kill cyperaceae weeds such as heterotype cyperus rotundus, cyperus rotundus and the like, gramineous weeds such as barnyard grass, barnyard grass and moleplant seed and broadleaf weeds such as monochoria vaginalis, edible tulip, ludwigia prostrata and the like in crop fields, and has the characteristics of expanding weed control spectrum, reducing application amount, generating synergistic action, solving resistant weeds and the like.

The invention also provides an application of the weeding composition in weed control; and to provide a method of controlling unwanted plant growth comprising applying the herbicidal composition to a plant, part of a plant, plant seed, or area where a plant is growing.
In addition, the compositions according to the invention can be applied by spraying to the foliage of the plants to be treated, i.e. to the weeds, in particular to surfaces infested or susceptible to infestation by weeds.
When the herbicidal composition of the present invention is applied, an unexpected synergistic effect is obtained, and the herbicidal activity is more remarkable than the expected sum of the activities using individual herbicides, and the activities of the individual herbicides. The synergistic effect is manifested by reduced application rates, a broader spectrum of weed control, and a faster and longer lasting herbicidal action, which are desirable in the practice of weed control. These new compositions are clearly superior to existing herbicides in terms of the properties described, achieving reduced use and being more environmentally friendly.
The synergistic herbicidal composition of the invention also has the following advantages:
(1) the composition of the invention is environment-friendly and is easy to degrade in the environment.
(2) The weeding composition has low cost and convenient use, and has great economic and social benefits when being popularized and applied.
