Abstract
The efficacy of an agricultural chemical can be enhanced by using an enhancer for agricultural chemicals represented by the following formulas (I) or (II) together with the agricultural chemical: ##STR1## The enhancer for agricultural chemicals according to the present invention can safely be applied to various crops without doing chemical injury thereto.
Claims21
An agricultural chemical composition which comprises:
- (a) an agricultural chemical;
- and
- (b) one or more enhancers of the formula (2) or (4) ##STR92## wherein R.sup.1 represents a linear or branched alkyl group or alkenyl group having 5 to 29 carbon atoms;
- R.sup.2 and R.sup.3 may be the same or different and each represents a hydrogen or --C(O)--R.sup.7 wherein R.sup.7 represents a linear or branched alkyl group or alkenyl group having 5 to 29 carbon atoms;
- p, q, r may be the same or different and each represents a positive number of 1 to 30 on the average;
- R.sup.4, R.sup.5, and R.sup.6 may be the same or different and each represents hydrogen or a methyl group, or a mixture of hydrogen and a methyl group;
- or an enhancer having the formula ##STR93## wherein R.sup.8 is ##STR94## R.sup.9 and R.sup.10 may be the same or different and are each hydrogen or --C(O)--R.sup.18, with the proviso that when R.sup.8 is ##STR95## R.sup.9 and R.sup.10 are the same (wherein R.sup.18 represents a linear or branched alkyl group or alkenyl group having 5 to 29 carbon atoms);
- R.sup.11 represents hydrogen, an alkyl group having 1 to 4 carbon atoms, a hydroxyalkyl group having 1 to 4 carbon atoms or a benzyl group;
- R.sup.12, R.sup.13, R.sup.15 and R.sup.17 may be the same or different and each represents hydrogen or a methyl group, or a mixture of hydrogen and a methyl group;
- R.sup.14 represents a linear or branched alkyl group or alkenyl group having 5 to 29 carbon atoms;
- R.sup.16 represents hydrogen or a linear or branched alkyl group or alkenyl group having 1 to 30 carbon atoms;
- s, t and u may be the same or different and each represents a positive number of 1 to 30 on the average;
- v represents a number of 0 to 30 on the average;
- k represents 1 to 5;
- and
- X.sup.- represents a counter ion.

- R.sup.11 represents hydrogen, an alkyl group having 1 to 4 carbon atoms, a hydroxyalkyl group having 1 to 4 carbon atoms or a benzyl group;
- R.sup.12, R.sup.13, R.sup.15 and R.sup.17 may be the same or different and each represents hydrogen or a methyl group, or a mixture of hydrogen and a methyl group;
- R.sup.14 represents a linear or branched alkyl group or alkenyl group having 5 to 29 carbon atoms;
- R.sup.16 represents hydrogen or a linear or branched alkyl group or alkenyl group having 1 to 30 carbon atoms;
- s, t and u may be the same or different and each represents a positive number of 1 to 30 on the average;
- v represents a number of 0 to 30 on the average;
- k represents 1 to 5;
- and
