Abstract: An agricultural chemical composition which can be safely applied to crops without causing any chemical damage comprising a mixture, which exerts excellent potentiating effects on various agricultural chemicals and has n of from 2 to 50 on the average and x1+y1+z1+x2+y2+z2+x3+y3+z3 of from 0 to 100 on the average, of compounds represented by the following general formula (I) and an agricultural chemical, wherein the weight ratio of the mixture to the agricultural chemical ranges from 0.1 to 20: ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 each represent a hydrogen atom or an acyl group having from 2 to 31 carbon atoms, --SO.sub.3 Na, --SO.sub.3 K, --SO.sub.3 H.N(C.sub.2 H.sub.4 OH).sub.3 or --SO.sub.3 H.NH(C.sub.2 H.sub.4 OH).sub.2 ;(EO).sub.x1, (EO).sub.x2 and (EO).sub.x3 each represent a polyoxyethylene chain;(PO).sub.y1, (PO).sub.y2 and (PO).sub.y3 each represent a polyoxypropylene chain;(BO).sub.z1, (BO).sub.z2 and (BO).sub.

Abstract: A liquid enhancer composition for amino acid series herbicides comprising specific tertiary amine and a derivative thereof, at least one oxalic acid or a salt thereof selected from the group consisting of oxalic acid, potassium oxalate, alkanolamine salts of oxalic acid, and lower alkylamine salts of oxalic acid, wherein the ratio of oxalic acid or the salt thereof is 0.1 to 10 times mole per mole of the nitrogen-containing compound.The enhancer composition of the present invention has an excellent stability with lapse of time to a change in temperatures and can markedly enhance the medicinal efficacy of an amino acid series herbicide even when the composition is used in a liquid form in combination with the herbicide.

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.

Abstract: 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: ##STR1## wherein R.sup.1 represents a linear or branched alkyl or alkenyl group having 5 to 29 carbon atoms; each R.sup.2 represents a hydrogen atom or a methyl group; each R.sup.3 represents a hydrogen atom or a methyl group; R.sup.4 and R.sup.5 may be the same or different from each other and each independently represents a hydrogen atom, a group represented by the formula: ##STR2## wherein R.sup.6 represents a linear or branched alkyl or alkenyl group having 1 to 29 carbon atoms, or a group represented by the formula: --CH.sub.2 COOX, wherein X represents a hydrogen atom, a sodium atom, a potassium atom, an ammonium group or an organic ammonium group.

Abstract: A method for enhancing the effectiveness of an agricultural chemical which comprises incorporating a specific enhancer into a diluted solution of the agricultural chemical.The specific enhancer is a quaternary ammonium salt or a amine.

Abstract: N-(3,3-Diphenylpropyl)-N'-aralkyl-substituted piperazines which have a structure in which a hydrogen in the N'-benzene ring has been substituted for by --(OCH.sub.3).sub.n (in which n represents an integer from 0 - 3) were synthesized. These compounds are novel compounds that are not found in literature, and have a coronary blood flow increasing action in considerably lower amounts than do conventional piperazine compounds having similar effects.
