Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a first component optionally selected from the group consisting of N- (phosphonomethyl) glycine and salts thereof, a second component optionally selected from organic and inorganic metal salts (group b), The present invention relates to an aqueous suspension pesticide composition containing water and an oily pesticide component, a method for producing the same, or use thereof as a herbicide.

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 Science, 39 , 622-628 (1991)｝, a narrow range of doses showing the herbicidal effect, narrower weed spectrum ,
It has drawbacks such as short duration of herbicidal effect, and has not been used as a practical herbicide. Therefore, development of a herbicide that overcomes the above drawbacks has been desired.

[0005] On the other hand, an aqueous suspension pesticide composition containing glyphosate and an oily pesticide component is described in JP-A-9-241111, which discloses a metal such as the second component of the present invention. No salt is described, and the aqueous suspension pesticidal composition destroys weeds and cannot be used as a herbicide with less withering as in the present invention.

BEST MODE FOR CARRYING OUT THE INVENTION The aqueous suspension pesticide composition of the present invention comprises:
For example, it can be manufactured as follows.

Glyphosate is neutralized with various bases. The base used at this time is usually an organic base or an inorganic base, preferably a primary amine, an alkali metal hydroxide salt or an alkaline earth metal, more preferably isopropylamine, hydroxide Sodium. Glyphosate is used in an amount slightly more than equimolar to the amount of glyphosate acid in order to obtain an aqueous suspension formulation having stable physical properties, or to omit the use of a crushing device in a later manufacturing process. It is desirable to use it in advance and to be in a completely aqueous solution state.

The above-mentioned second component is gradually added to the aqueous solution in which glyphosate is dissolved while stirring, and the mixture is stirred for a while. Suspension progresses gradually by the salt exchange reaction, and after obtaining a glyphosate slurry of solid particles suspension containing glyphosate, if necessary, the above-mentioned dispersant is gradually added to completely suspend the suspension. Stir until turbid to obtain a slurry containing glyphosate. Alternatively, the above-mentioned dispersant is gradually added to an aqueous solution in which glyphosate is dissolved or an aqueous solution to which water is further added while stirring, and the mixture is stirred until it is completely dissolved. When the dissolution is completed or when the solution becomes homogeneous, the second component is gradually added and stirred for a while. Suspension progresses gradually by the salt exchange reaction, and a slurry of solid particle suspension containing glyphosate is obtained. The slurry obtained by these methods is, if necessary, a wet pulverizing step, for example, a wet pulverizer such as a bead mill such as a dyno mill, an apex mill, a coball mill, a diamond fine mill, a system zeta, a ball mill, a vibration mill,
Medium stirring mill such as sand mill, Cavitron,
A high-speed shearing mill such as a disper mill, a colloid mill, a rotating disk mill such as a supermass colloider, and a high-pressure emulsifying dispersion mill such as a nanomizer and a microfluidizer may be used. Further, the composition can be obtained by mixing and stirring the composition of the oily pesticide drug substance, which has been uniformly suspended in water beforehand forcibly or spontaneously with a surfactant, together with the slurry and, if necessary, a thickener.

As a simpler method of preparing an aqueous suspension composition containing an oily agricultural chemical component, a thickener is added to the oily agricultural chemical component, and water is added with stirring, followed by stirring. Next, an aqueous solution of a glyphosate salt is added, and the second component is gradually added with stirring, followed by stirring for a while.
By the salt exchange reaction, the suspension gradually progresses, and after the slurry is obtained, the dispersant is gradually added, and the mixture is stirred until it is completely homogeneously suspended. An agrochemical composition is obtained. At this time, the order of charging the second component and the dispersant is not limited.

If the aqueous suspension pesticide composition is not sufficiently dispersed, a colloid mill, a static mixer,
Shearing can be performed using a turbo stirrer, polytron, dispermill, homomixer, or similar device. Also, if the viscosity decreases due to such shearing,
The viscosity is increased by increasing the amount of the thickener added. If the viscosity of the aqueous turbid pesticide composition of the present invention is too high, it lacks in water dispersibility, and if it is too low, solids are separated and there is a concern that the solids may collect at the bottom of the container.

[0095]

The aqueous suspension pesticide composition containing the oily pesticidal component of the present invention can be obtained as a preparation having excellent physical stability.

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 (the action of killing the roots of a plant) possessed by glyphosate or a salt thereof, 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 over a wide spectrum over a long period of time by adding an oily pesticide component.

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.

The aqueous suspension pesticide composition of the present invention contains a dispersing agent and a wetting agent, thereby improving the herbicidal effect and sustainability thereof without killing the plants, and further stabilizing the aqueous suspension. The present invention provides a cloudy preparation, whereby weeds can be managed more easily than before.
