Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel agrochemical efficacy enhancer, an agrochemical efficacy enhancer composition, and an agrochemical composition containing the same.

[0002]

2. Description of the Related Art Insecticides, fungicides, herbicides,
Pesticides such as acaricides and plant growth regulators are used in dosage forms such as emulsions, wettable powders, granules, powders and flowable agents. At that time, various contrivances have been made in terms of the physical properties of the preparation in order to sufficiently bring out the effect of the pesticidal drug substance, but it is currently difficult to further enhance the effect of the pesticide by devising the preparation. Further, since the development of new pesticides is more difficult, it is of great industrial significance to further enhance the activity of existing pesticides.

Up to now, surfactants composed of various nitrogen-containing compounds such as quaternary ammonium salts, betaines and amine oxides have been known as those having an effect of enhancing the activity of agricultural chemicals (Japanese Patent Laid-Open No. 2000-242242). Sho 63-145205
issue). Among them, it is known that a quaternized or further polyoxyethylenated long chain amine is particularly effective. However, the above-mentioned drug efficacy-enhancing effect, which has the activity-enhancing effect of agricultural chemicals, has not yet been satisfactory.

[0004]

[Means for Solving the Problems] The inventors of the present invention have conducted further diligent studies in order to find a potency enhancer for pesticides which enhances the potency of pesticides by combining it with a pesticide bulk. The inventors have found that alkanolamides have a potentiating effect on various pesticides, and completed the present invention.

That is, the present invention provides an agrochemical potency enhancer containing a compound represented by the general formula (I) as an active ingredient.

[0006]

[Chemical 2]

[Wherein R ^{1 is} a linear or branched alkyl group or alkenyl group having 5 to 29 carbon atoms R ² , R ^{3 are the} same or different and are hydrogen or a methyl group or a mixture of hydrogen and a methyl group n: average Represents a number of 1 to 30 m: represents a number of 0 to 30 on average. ].

The compound of the general formula (I) according to the present invention can be converted into a fatty acid monoethanolamide by, for example, obtaining a fatty acid monoethanolamide from a fatty acid and monoethanolamine and further adding an alkylene oxide to the fatty acid monoethanolamide. An alkylene oxide adduct is obtained. Some of this type is commercially available, for example ethylene oxide adduct of coconut oil fatty acid monoethanolamide (2
Mol, 5 mol, 10 mol adduct) are commercialized by Kawaken Fine Chemicals Co., Ltd. as Amizet 2C, 5C and 10C, respectively.

By using diethanolamine instead of monoethanolamine in the same manner as described above, a fatty acid dialkanolamide and its alkylene oxide adduct are obtained. The compound of the general formula (I) can also be obtained by using isopropanolamines instead of the ethanolamines.

Of course, the method for producing the compound of the general formula (I) according to the present invention is not limited to these.

The compounds of the general formula (I) according to the present invention are preferably those in which n is an average of 1 to 20 and m is an average of 0 to 20, and more preferably n is 1 to an average. The number is 10 and the number m is 0 to 10 on average. Particularly in the present invention, it is preferable to use a compound in which m and n are in this range and the number is in the range of 1 ≦ m + n <25. Further, R ¹ in the general formula (I) is preferably a linear or branched alkyl group or alkenyl group having 7 to 21 carbon atoms, and the raw material fatty acid is coconut oil fatty acid, palm oil fatty acid, beef tallow fatty acid, lauric acid, myristin Those using an acid, palmitic acid, stearic acid, or oleic acid are more preferably used. Further, the alkylene oxide is R ^2, R ³ is ethylene oxide is preferably a hydrogen, mixed addition products of R ^2, R ³ is a mixture of hydrogen and methyl groups of ethylene oxide and propylene oxide are also preferably used.

The potentiator for agricultural chemicals comprising the compound of the above-mentioned general formula (I) of the present invention has no phytotoxicity when used in combination with the agricultural chemical bulk, and can increase the efficacy of the agricultural chemical bulk by 2 to 3 times. .

The fatty acid alkanolamide is a known substance and is used as a stabilizer for foams such as shampoos. In the field of agricultural chemicals, JP-A-58-128301 discloses an aqueous suspension agricultural chemical composed of a sparingly water-insoluble agricultural chemical active ingredient, a polyhydric alcohol type nonionic surfactant, a thickener and the like. However, this is for the purpose of stabilizing the aqueous suspension pesticide. Further, there is an example in which a fatty acid alkanolamide is used as a stabilizer of a pyrethroid insecticide in JP-A-4-41406 and a stabilizer of a pyrethroid compound and / or an organic phosphorus compound in JP-A-2-142708. Further, Japanese Patent Publication No. 63-41884 describes that alkanolamides are effective for killing and / or killing extracorporeal parasites, but the subject is only "shirami". That is, it has not been known at all until now that fatty acid alkanolamides have the effect of enhancing the efficacy of pesticides, and was first discovered by the present invention.

The mechanism of whether the potency enhancer for pesticides containing the compound represented by the general formula (I) according to the present invention as an active ingredient exhibits a remarkable potency-enhancing action regardless of the type of the pesticide structure is not necessarily a mechanism. Although it is not clear, it is considered that one of them is that the potency enhancer of the present invention has a very strong solubilizing power for pesticides and thus makes the pesticides into fine particles and promotes penetration into plants, insect bodies, and fungi.

In Examples 1 to 4, the potency of the agrochemical potency enhancer of the present invention was compared with the case where a general tertiary amine or a cationic surfactant was used as the agrochemical potency enhancer (comparative product). The test is shown. As is clear from Tables 4 to 11, the pesticidal efficacy enhancer of the present invention exhibited a remarkable effect and was at a practical level, but the comparative product showed some enhancement of pesticidal efficacy, but was at a practical level. There was no effect to reach.
Therefore, it can be seen that the pesticidal potency enhancer of the present invention specifically enhances the potency of pesticides as compared with general tertiary amines or cationic surfactants.

Example 5 Roundup liquid as herbicide (41% by weight of active ingredient)
The same test as in Example 1 was conducted using the active ingredient 7, the active ingredient 18, and the active ingredient 25 of Example 1 as the efficacy enhancer, and using these in the amounts shown in Table 12. It was The results are shown in Table 12. In Table 12, the "pesticide raw material" means the active ingredient of the herbicide.
