DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to one or more first components selected from non-selective phosphate herbicides (group a) and one or more first components selected from phosphorous acid derivatives and the like (group b). Or 2

2. Description of the Related Art In a site such as a railway site, a highway, an open vacant lot, a factory site, an embankment, a paddy field ridge, an orchard, a paddy field and a field before plowing, if weeds are left unobstructed, the visibility of transportation is obstructed. And may become a source of pests, hinder agricultural work, and cause various other adverse effects. However, given the recent labor shortage and rising labor costs, it is difficult to control these weeds with only human power and machines, and non-selective herbicides such as glyphosate, glyphosin, bialaphos, and glufosinate. The use of is becoming important.

When the above non-selective herbicides are used at a lethal dose of weeds on a slope such as a slope or in a paddy field levee, the above-mentioned non-selective herbicides almost completely kill the weeds and soil. The surface is bare and soil runoff is a problem. Therefore, in these situations, an agent that does not completely kill the weeds but leaves various weeds as green and suppresses their growth for a long time, that is, an herbicide is desired. In addition, in the actual weed control scene, when spraying a chemical, there is a variation in the amount of the drug applied depending on the location due to the wind or the like. Required. In other words, a herbicide that does not kill the roots of the weeds even if it is applied slightly more than the reference amount of applied medicine, and that exhibits an herbicidal action even when applied somewhat less than the reference amount of applied medicine. Development is desired.

[0004] Attempts have been made to use the above non-selective herbicides in reduced doses, or to add a drug that suppresses the herbicidal activity of the non-selective herbicides to use them as herbicides ( JP-B-56-6402, JP-A-59-101500, Weed S
cience, 39 , 622-628 (1991)). Therefore, development of an herbicide that overcomes the above-mentioned disadvantages has been desired.
