Problems solved by technology

However, since some herbicides have been used for many years, some weeds have become resistant to them, and the number of difficult-to-preventive weeds to which these herbicides are ineffective or barely effective has been increasing, it is highly desirable to develop Herbicides that have a broad herbicidal spectrum and

Abstract

The invention provides a herbicide composition consisting of 2-[(4,6-dimethoxypyrimidin-2-yl)hydroxy-methyl]-6-methoxymethyl-N-difluoromethanesulfonylanilide as the component (A) and any compound selected from more than 20 kinds of specific compounds such as orbencarb and the like as the component (B), heretofore not combined with the component (A) compound. Dispensation of the herbicide composition to paddy fields, lawns, dry fields, or non-agricultural lands gives excellent weed-controlling effects on a variety of weeds and causes no or little phytotoxicities on valuable cultivated plants.

Description

technical field [0001] The present invention relates to a novel herbicidal composition and a method for controlling weeds using the composition, and more particularly, to a method capable of effectively preventing the growth of weeds and removing weeds from paddy fields, lawns, upland fields or non-weed fields even with only one treatment. Various types of weeds growing in agricultural land, especially paddy fields without inhibiting the growth of valuable cultivated plants such as rice, barley, wheat, etc., lawn grass, etc., and new herbicidal composition for controlling paddy fields by applying the herbicidal composition , lawns, dry fields or weeds in non-agricultural land. Background technique [0002] Heretofore, various types of herbicides have been developed, and these herbicides contribute to improvement of agricultural productivity and labor saving. However, since some herbicides have been used for many years, some weeds have become resistant to them, and the numbe...
