BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to a novel agricultural chemical composition. 
2. Description of the Related Art 
Agricultural chemical compositions such as insecticide compositions, 
bactericide compositions, herbicide compositions, miticide compositions 
and plant growth regulator compositions have been used in various forms, 
for example, emulsions, wettable powders, granules, dusts or flowables. In 
the preparation of these agricultural chemical compositions, various 
attempts have been made to make good use of the efficacy of the 
agricultural chemical, but it has been found to be difficult under current 
circumstances to further potentiate the agricultural chemical through 
formulated contrivances. Further, it is difficult to develop various novel 
agricultural chemicals. Thus it is highly important from an industrial 
viewpoint to further potentiate the existing agricultural chemicals. 
There have been known various surfactants which are nitrogen containing 
compounds (for example, quaternary ammonium salts, betaines and amine 
oxides) which can potentiate agricultural chemicals (refer to Japanese 
Patent Laid-Open No. 145205/1988). It is also known that quaternized 
ammonium salts comprising a long-chain alkyl group(s) and quaternized 
ammonium salts comprising a long-chain alkyl group(s) and a 
polyoxyethylene unit(s) are particularly effective therefor from among 
these surfactants. The above-mentioned quaternized ammonium salts capable 
of potentiating agricultural chemicals have halogen atoms as the counter 
ion. However the potentiating effects thereof are still unsatisfactory. 
In 11691 Chemical Products (page 906, published on Jan. 23, 1991, ed. by 
The Chemical Daily Co., Ltd.) there was a quaternized di(hydroxyethylene) 
alkyl methyl ammonium methosulfate represented by the following formula

Further scope and the applicability of the present invention will become 
apparent from the detailed description given hereinafter. However, it 
should be understood that the detailed description and specific examples, 
while indicating preferred embodiments of the invention, are given by way 
of illustration only, since various changes and modifications within the 
spirit and scope of the invention will become apparent to those skilled in 
the art from this detailed description. Detailed Description of the 
Invention: 
in the present invention, a mixture consisting essentially of compounds 
represented by the above-mentioned general formula (I) and having 
(n1+n2+n3) and (n4+n5+n6) each being a number of 0 to 100 on the average 
is used as an adjuvant. Namely, a mixture of compounds represented by the 
above general formula (I), which differ from each other at least one among 
n1, n2, n3, n4, n5 and n6, is employed. Certainly, a mixture comprising 
two or more of the above-described mixtures may be used as adjuvants. 
In the above general formula (I), R.sub.1, R.sub.2 and R.sub.3 each 
represent a straight-chain or branched alkyl, alkenyl or hydroxyalkyl 
group having from 1 to 30 carbon atoms. 
In the compounds represented by the general formula (I) according to the 
present invention, it is preferable that R.sub.1 represents a 
straight-chain or branched alkyl, alkenyl or hydroxyalkyl group having 
from 8 to 24 carbon atoms. Specific examples thereof include octyl, decyl, 
lauryl, myristyl, palmityl, stearyl and oleyl groups. When two or more of 
the mixtures are employed, it is recommended to use mixtures consisting 
essentially of compounds wherein R.sub.1 represents a group selected from 
among those cited above. On the other hand, R.sub.2 and R.sub.3 may each 
preferably represent a straight-chain or branched alkyl, alkenyl or 
hydroxyalkyl group having from 1 to 4 carbon atoms. Specific examples 
thereof include methyl, ethyl, hydroxyethyl and hydroxypropyl groups. 
The compound represented by the general formula (I) has at least one of a 
polyoxyethylene chain, a polyoxypropylene chain and a polyoxybutylene 
chain. That is, at least one of n1, n2, n3, n4, n5 and n6 is an integer of 
1 or more. 
When two or three kinds of alkylene oxide chains are present in the general 
formula (I), the addition of the alkylene oxide chains may be in block or 
at random. 
The average of the numbers (n1+n4) of moles of the ethylene oxide added of 
the compounds constituting the mixture according to the present invention 
is taken as the number of moles of the ethylene oxide added of the 
mixture, the average of the numbers (n2+n5) of moles of the propylene 
oxide added of the compounds constituting the mixture is taken as the 
number of moles of the propylene oxide added of the mixture, and the 
average of the numbers (n3+n6) of moles of the butylene oxide added of the 
compounds constituting the mixture is taken as the number of moles Of the 
butylene oxide added of the mixture. 
In the general formula (I), (n1+n2+n3) and (n4+n5+n6) are each 0 or a 
positive integer provided that at least one of (n1+n2+n3) and (n4+n5+n6) 
is 1 or more. 
The average of each the (n1+n2+n3)s and (n4+n5+n6)s of the compounds 
represented by the general formula (I), in other words, the (n1+n2+n3) of 
the mixture according to the present invention and the (n4+n5+n6) of the 
mixture according to the present invention is from 0 to 100, preferably 
from 0 to 50 and still preferably from 1 to 25. When these numbers exceed 
100, the resulting compound has an excessively high molecular weight, 
which lowers the potentiating action per unit weight. 
The (n1+n2+n3+n4+n5+n6) of the mixture according to the present invention 
is 1 or above, preferably from 1 to 100 and still preferably from 2 to 50. 
Among the mixtures according to the present invention, quaternized 
N,N,N,N-lauryl ethyl di[(poly)oxyethylene] (n1+n4=2) ammonium ethyl 
sulfate, which is a mixture of quaternized N,N,N,N-lauryl ethyl 
di[(poly)oxyethylene] ammonium ethyl sulfates differing from each other 
only in the number (n1+n4) of moles of the polyoxyethylene chain and which 
has an average number of moles the polyoxyethylene chains (n1+n4) of 2, is 
particularly suitable in the present invention. Furthermore, quaternized 
N,N,N,N-oleyl methyl di[(poly)oxyethylene] (n1+n4=2) ammonium 
methylsulfate, quaternized N,N,N,N-lauryl methyl di[(poly)oxyethylene] 
(n1+n4=15) ammonium methylsulfate and quaternized N,N,N,N-oleyl methyl 
di[(poly)oxypropylene] (n2+n5=14) ammonium methylsulfate are preferable. 
The mixture consisting essentially of compounds represented by the general 
formula (I) according to the present invention may be produced by any 
commonly known method. For example, it may be obtained by adding dropwise 
a lower alkyl sulfate to a di(polyoxyalkylene)monoalkylamine at a high 
temperature (70.degree. to 90.degree. C.) followed by aging. The alkyl 
group of the di(polyoxyalkylene)monoalkylamine to be used as the starting 
material in this reaction is a straight-chain or branched alkyl group 
having from 1 to 30 carbon atoms. Alternately, an amine having an alkenyl 
group, which has a double bond in the chain, or a hydroxyalkyl group, 
which has a hydroxyl group in the chain, instead of the alkyl group may be 
used. It is preferable that the starting amine has a hydrocarbon group, 
such as an alkyl group, having from 8 to 24 carbon atoms. It is still 
preferable that the starting amine has a hydrocarbon group having from 8 
to 24 carbon atoms and from 0 to 4 (still more preferably from 0 to 2) 
double bonds and/or from 0 to 4 (still more preferably from 0 to 2) 
hydroxyl groups. 
When used together with an agricultural chemical, the mixture consisting 
essentially of the compounds represented by the above general formula (I) 
as an adjuvant can enhance the effects of the agricultural chemical twice 
or thrice without causing any chemical damage. 
It is not necessarily evident why the mixture comprising compounds 
represented by the above general formula (I) according to the present 
invention has the remarkable effect of potentiating any agricultural 
chemicals irrespective of its structure. It is conceivable, however, that 
one reason therefor may reside in the fact that the mixture according to 
the present invention has such a potent power of solubilizing the 
agricultural chemical that the agricultural chemical becomes finely 
grained, thus promoting the diffusion of the agricultural chemical on a 
surface of a plant, an insect or a bacterial cell thus facilitating the 
permeation of the agricultural chemical into the plant, insect or 
bacterial cell. 
When the mixture comprising compounds represented by the general formula 
(I) according to the present invention is used together with a surfactant 
other than the compounds represented by the general formula (I), the 
amount of the mixture can be reduced and the stability of an agricultural 
chemical composition can be increased while the potentiating effect of the 
mixture on agricultural chemicals is maintained. Examples of the 
surfactant usable herein include nonionic, anionic, cationic and 
amphoteric surfactants, and mixtures thereof. 
Examples of the nonionic surfactants include polyoxyethylene alkyl ethers, 
polyoxyethylene alkylaryl ethers, polyoxyethylene alkylaryl 
ether/formaldehyde condensates, polyoxyalkylene aryl ethers, 
polyoxyalkylene alkyl esters, polyoxyalkylene alkyl sorbitol esters, 
polyoxyalkylene sorbitan esters, polyoxyalkylene alkyl glycerol esters, 
polyoxyalkylene block copolymers, polyoxyalkylene block copolymer 
alkylglycerol esters, polyoxyalkylene alkyl sulfonamides, polyoxyalkylene 
rosin esters, polyoxypropylene block copolymers, polyoxyethylene oleyl 
ethers, polyoxyalkylene alkylphenols and mixtures consisting of two or 
more of these substances. 
Examples of the cationic surfactants include polyoxyalkylamines such as 
ethoxylated tallow amine, ethoxylated oleylamine, ethoxylated soy amine, 
ethoxylated coco amine, ethoxylated synthetic alkylamine and ethoxylated 
octylamine and mixtures consisting of two or more of these substances. 
Examples of the anionic surfactants, which are typically available in the 
form of an aqueous solution or a solid, include sodium aryl sulfate, 
sodium mono- or di-alkylnapthalenesulfonates, sodium 
.alpha.-oleinsulfonate, sodium alkanesulfonate, alkyl sulfates, 
polyoxyalkylene alkyl ether sulfonates, polyoxyalkylene alkylaryl ether 
sulfates, polyoxyalkylene styrylphenyl ether sulfates, mono- or 
di-alkylbenzenesulfonates, alkylnapthalenesulfonates, 
alkylnaphthalenesulfonate/formaldehyde condensates, alkyl diphenyl ether 
sulfonates, olefinic sulfonates. alkyl phosphates, polyoxyalkylene alkyl 
phosphates, polyoxyalkylene phenyl ether phosphates, polyoxyalkylphenol 
phosphates, polycarboxylic acid salts, fatty acid salts, stearic acid and 
its salts, oleic acid and its salts, N-methyl fatty acid taurides and 
mixtures consisting of two or more compounds selected from among those 
cited above, involving sodium, potassium, ammonium and amine salts. 
Examples of suitable amphoteric surfactants include lauryldimethylamine 
oxide, Armox C mfd. by Lion Co., Ltd., Carinal mfd. by Toho Chemical Co., 
Ltd., Amphitol 24B mfd. by Kao Corporation, betaines, other amine oxides 
and mixtures consisting of two or more substances selected from among 
those cited above. 
Among these surfactants, nonionic surfactants are particularly preferable. 
It is still preferable to use ester-type surfactants such as 
polyoxyalkylene sorbitan esters and polyoxyalkylene alkyl glycerol esters; 
polyoxyalkylene alkyl ethers and polyoxyalkylene alkylnonylphenols. 
Although the ratio of the mixture comprising compounds represented by the 
general formula (I) to the surfactant other than the compounds represented 
by the general formula (I) in the agricultural chemical composition (2) is 
not particularly restricted, the weight ratio of the mixture comprising 
compounds represented by the general formula (I) to the surfactant other 
than the above-described compounds may range from 1/10 to 50/1, preferably 
from 1/1 to 10/1. 
The agricultural chemical composition (1) of the present invention 
comprises the mixture comprising compounds represented by the general 
formula (I) as an adjuvant and an agricultural chemical. It is necessary 
for the agricultural chemical composition (1) of the present invention to 
have a weight ratio of the adjuvant to the agricultural chemical within a 
range of from 0.1 to 50, preferably from 0.1 to 10. When this weight ratio 
is below 0.1, no satisfactory effect can be achieved. When this ratio 
exceeds 50, on the other hand, the effect cannot be further improved. 
The agricultural chemical composition (2) of the present invention 
comprises the mixture comprising compounds represented by the general 
formula (I) and the surfactant other than the compounds represented by the 
general formula (I) as the adjuvants and an agricultural chemical. It is 
necessary for the agricultural chemical composition (2) of the present 
invention to have a weight ratio of the total amount of the adjuvants to 
the agricultural chemical within a range of from 0.1 to 50, preferably 
from 0.1 to 10. When this weight ratio is below 0.1, no satisfactory 
effect can be achieved. When this ratio exceeds 50, on the other hand, the 
effect cannot be further improved. 
The agricultural adjuvant(s) according to the present invention can be 
safely applied to various crops without causing any chemical damage. 
The agricultural chemical compositions (1) and (2) of the present invention 
may be in any preparation form, for example, an emulsion, a wettable 
powder, granules, a flowable powder or dusts, without restriction. Thus, 
the agricultural chemical compositions (1) and (2) according to the 
present invention may further contain other additives such as emulsifiers, 
dispersing agents and supports depending on the preparation form. 
Now, agricultural chemicals and agricultural chemical compositions (i.e., 
agricultural chemical formulations) which can be used in the preparation 
of the agricultural chemical compositions (1) and (2) of the present 
invention will be described, though it is to be understood that the 
present invention is not restricted thereto.
