DESCRIPTION:
BRIEF SUMMARY
This application has been filed under 35 USC 371 as the national stage of international application PCT/JP95/00996, filed May 24, 1995.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a novel enhancer for agricultural chemicals, a novel enhancer composition for agricultural chemicals and a method for enhancing the efficacy of an agricultural chemical.
2. Description of the Related Art
Agricultural chemicals including insecticides, fungicides (or bactericides), herbicides, miticides (or acaricides) and plant growth regulators have been used in the forms of, for example, emulsions, wettable powders, granules, dusts and flowables. In the properties of these agricultural chemical preparations, various attempts have been made to achieve the maximum efficacy of the agricultural chemical. However, it has been difficult to enhance the efficacies of agricultural chemicals through adjustments in formulations. It is further difficult to develop novel agricultural chemicals. Therefore, further enhancement of the efficacies of existing agricultural chemicals would highly contribute to the industry.
As substances capable of enhancing the efficacies of agricultural chemicals, surfactants comprising various nitrogen-containing compounds such as quaternary ammonium salts, betaines and amine oxides have been known. It is known that quaternized or further polyoxyethylenated long-chain amines, among the above-mentioned compounds, are effective for this purpose. However, the effects of the above described compounds capable of enhancing the efficacies of agricultural chemicals are not always satisfactory.
DISCLOSURE OF THE INVENTION
Summary of the Invention
The present inventors have made studies for the purpose of finding a compound which can enhance the efficacies of agricultural chemicals. As a result of the studies, they have found that a specific trialkanolamine derivative and a quaternized compound thereof can enhance the efficacies of various agricultural chemicals. The present invention has been accomplished on the basis of this finding.
Thus, the present invention provides an enhancer for agricultural chemicals represented by the following formula (I): ##STR2##
wherein R.sup.1, R.sup.2 and R.sup.3 may be the same or different from one another and each independently represents a hydrogen atom, a linear or branched alkyl or alkenyl group having 5 to 29 carbon atoms, a group represented by the formula: ##STR3## wherein R.sup.7 represents a linear or branched alkyl or alkenyl group having 5 to 29 carbon atoms, or a group represented by the formula: ##STR4## wherein R.sup.a represents a linear or branched alkyl or alkenyl group having 5 to 29 carbon atoms, R.sup.b represents a hydrogen atom or a linear or branched alkyl or alkenyl group having 1 to 30 carbon atoms, and n is a number of 1 to 6, with the proviso that at least one of R.sup.1, R.sup.2 and R.sup.3 is(are) not a hydrogen atom(s);
p, q and r each represents an average value, may be the same or different from one another and are each independently a number of 1 to 30;
R.sup.4 and R.sup.4' are both hydrogen atoms or both methyl groups, or one of R.sup.4 and R.sup.4' is a hydrogen atom and the other is a methyl group or an ethyl group, the group represented by the formula: ##STR5## wherein R.sup.4, R.sup.4' and p are each as defined above, may include different units of ##STR6## wherein R.sup.4 's may be different from one another and R.sup.4' 's may be so;
R.sup.5 and R.sup.5' are both hydrogen atoms or both methyl groups, or one of R.sup.5 and R.sup.5' is a hydrogen atom and the other is a methyl group or an ethyl group, the group represented by the formula: ##STR7## wherein R.sup.5, R.sup.5' and q are each as defined above, may include different units of ##STR8## wherein R.sup.5 's may be different from one another and R.sup.5' 's may be so; and
R.sup.6 and R.sup.6' are both hydrogen atoms or both methyl groups, or one of R.sup.6 and R.sup.6' is a hydrogen atom and the other is a methyl group or an ethyl group, the g
