2. Description of the Related Art In a scene such as a railway site, a highway, a vacant lot, a factory site, an embankment, a paddy field ridge, an orchard, a paddy field and a field before cultivation, 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 using only human power and machines, and non-selective herbicides such as glyphosate, glyphosin, bialaphos and glufosinate are difficult to control. 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 cause soil damage. The surface is bare and soil runoff is a problem. Therefore, in these situations, there is a demand for 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. 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 somewhat more than the standard applied drug amount, and that exhibits an herbicidal action even when applied somewhat less than the standard applied drug amount. Development is desired.

Attempts have been made to reduce the amount of the above non-selective herbicides and use them as a herbicide by adding an agent that suppresses the herbicidal activity of the non-selective herbicide. JP-B-56-6402, JP-A-59-101500, Weed Sci
ence, 39, 622-628 (1991)｝, a practical herbicide that has the drawbacks of having a narrow range of doses showing the herbicidal effect, a narrower spectrum of the herbicidal effect, and a short duration of the herbicidal effect. The development of a herbicide that overcomes the above-mentioned disadvantages has been desired.

When the above composition did not contain a humectant, the treatment at a low concentration reduced the herbicidal effect, and re-growth of the plant was observed after the investigation. When the composition did not contain a dispersing agent, the plants died or yellowed when treated at a high concentration. When treated with glyphosate alone, the herbicidal effect was weak at low concentrations, and the plants died at high concentrations, and the dosage range that could be used as herbicides was narrow.

[0070]

The aqueous suspension pesticide composition of the present invention can be used as a herbicide.

That is, the aqueous suspension pesticidal composition of the present invention changes the plant killing action of glyphosate or a salt thereof (the action of killing the roots of a plant), and suppresses the growth without killing the plant. It can be used on slopes and levee such as slopes. The aqueous suspension pesticide composition of the present invention can maintain the herbicidal effect for a longer period of time by further adding maleic hydrazide or a salt thereof.

The use of glyphosate or a salt thereof can be expanded by utilizing the herbicidal action of the aqueous suspension pesticide composition of the present invention.

Further, the aqueous suspension pesticide composition of the present invention contains a dispersant and a wetting agent, so that the herbicidal effect and the sustainability thereof are improved without dying the plants, and a more stable aqueous suspension is provided. The present invention provides a cloudy preparation, whereby weeds can be managed more easily than before.
