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 are effective even on these difficult-to-preventive weeds
[0003] In addition, conventional herbicides often cause soil pollution and pollution of the surrounding environment, and in order to prevent such environmental pollution, it is desired to develop herbicides that are highly active and effective even in a small amount

Embodiment 1

[0035] To prepare a hydrated formulation: mix 1 part of 2-[(4,6-dimethoxypyrimidin-2-yl)hydroxymethyl]-6-methoxymethyl-N-difluoromethanesulfonanilide ( Hereinafter referred to as compound A), 12 parts of carfentrazone, 0.5 parts of polyoxyethylene octyl phenyl ether, 0.5 parts of β-naphthalenesulfonic acid-formaldehyde condensate sodium salt, 20 parts of diatomaceous earth and 66 parts of clay, and The mixture thus obtained is ground into powder.

Embodiment 2

[0037] Preparation of hydration preparation: Mix 2 parts of compound A, 20 parts of fenoxaprop, 0.5 parts of polyoxyethylene octyl phenyl ether, 0.5 parts of β-naphthalenesulfonic acid-formaldehyde condensate sodium salt, 20 parts of diatomaceous earth, 5 parts Parts of fumed silica (white carbon ink) and 52 parts of clay, and the mixture thus obtained was ground into powder.

Embodiment 3

[0039]Preparation of hydration preparation: mix 1 part of compound A, 10 parts of pendimethalin, 0.5 part of polyoxyethylene octyl phenyl ether, 0.5 part of β-naphthalenesulfonic acid-formaldehyde condensate sodium salt, 20 parts of diatomaceous earth, 5 parts of forge Silica (white carbon ink) and 63 parts of calcium carbonate were prepared, and the mixture thus obtained was ground into powder.

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 new herbicidal composition and a method for controlling weeds using the composition. More specifically, it relates to a method that can effectively prevent the growth of weeds and remove paddy fields, lawns, dry fields, or non-weeds even through a single treatment. A new herbicidal composition for agricultural land, particularly various types of weeds growing in rice fields without inhibiting the growth of valuable cultivated plants such as rice, barley, wheat, etc., turfgrass, etc., and the control of paddy fields by applying the herbicidal composition , Lawn, dry land or non-agricultural land. Background technique [0002] So far, various types of herbicides have been developed, and these herbicides contribute to the improvement of agricultural productivity and labor saving. However, since some herbicides have been used for many years, some weeds have developed resistance to them, and the number of weeds that are ineffec...
