ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a herbicidal composition.
BACKGROUND OF THE INVENTION
Currently, various herbicides are being utilized, but since there are various weeds that are target of control, and because the growth thereof continues for a long time, a herbicide that has a higher herbicidal activity, a quicker appearance of herbicidal effect, a wider herbicidal spectrum and a safety for crops is desired.
SUMMARY OF THE INVENTION
The present inventor has intensely studied to seek out an excellent herbicide, and has found that by applying a herbicidal composition which comprises, as active ingredients, (i) at least one compound selected from the group consisting of N-(phosphonomethyl)glycine (common name: glyphosate, hereinafter, referred to as glyphosate), a salt thereof and ammonium-DL-homoalanin-4-yl(methyl)phosphinate (common name: glufosinate-ammonium, hereinafter, referred to as glufosinate-ammonium), and (ii) ethyl 2-chloro-3-[2-chloro-5-(1,3-dioxo-4,5,6,7-tetrahydroisoindolin-2-yl)phenyl]acrylate (common name: cinidon-ethyl, hereinafter, referred to as cinidon-ethyl), various weeds that emerge or grow in crop-lands or non-crop-lands can be controlled effectively, and that the herbicidal effect produced thereby is synergistically increased as compared with the cases where the active ingredients are independently used. As such, the provided herbicidal composition can, therefore, be applied at a low amount. Moreover, by utilizing the inventive herbicidal compositions, the time necessary for appearance of a herbicidal effect can be shortened, a broadened weed control spectrum can be achieved and a wide variety of weeds can be controlled selectively, without producing problems of phytotoxicity against crops such as corn, soybean, wheat, barley, oat, rye and rice. Accordingly, the present invention has been obtained.
