THE EFFICACY OF AN AGRICULTURAL CHEMICAL CAN BE ENHANCED BY USING A SPECIFIC FATTY ACID ALKANOLAMIDE OR A FATTY ACID ESTER OR CARBOXYMETHYLATED DERIVATIVE THEREOF REPRESENTED BY THE FOLLOWING FORMULA (I) TOGETHER WITH THE AGRICULTURAL CHEMICAL:(FORMULA 1)WHEREIN R1 REPRESENTS A LINEAR OR BRANCHED ALKYL OR ALKENYL GROUP HAVING 5 TO 29 CARBON ATOMS; EACH R2 REPRESENTS A HYDROGEN ATOM OR A METHYL GROUP; EACH R3 REPRESENTS A HYDROGEN ATOM OR A METHYL GROUP; R4 AND R5 MAY BE THE SAME OR DIFFERENT FROM EACH OTHER AND EACH INDEPENDENTLY REPRESENTS A HYDROGEN ATOM, A GROUP REPRESENTED BY THE FORMULA: 0 - C-R6, WHEREIN R6 REPRESENTS A LINEAR OR BRANCHED ALKYL OR ALKENYL GROUP HAVING 1 TO 29 CARBON ATOMS, OR A GROUP REPRESENTED BY THE FORMULA : -CH2COOX, WHEREIN X REPRESENTS A HYDROGEN ATOM, A SODIUM ATOM, A POTASSIUM ATOM, AN AMMONIUM GROUP OR AN ORGANIC AMMONIUM GROUP; M IS A NUMBER OF 0TO 30; AND N IS A NUMBER OF 1 TO 30. THE FATTY ACID ALKANOLAMIDE AND THE ESTER AND CARBOXYMETHYLATED DERIVATIVE THEREOF ACCORDING TO THE PRESENT INVENTION CAN SAFELY BE APPLIED TO VARIOUS CROPS WITHOUT DOING CHEMICAL INJURY THERETO.
