PURPOSE:To obtain the subject composition capable of reducing using dose and expanding of administration, containing N-dichlorphenyl-1-oxyphenyl-4- carboxylic acid amide derivative and 2-chloroethyltrimethylammonium chloride. CONSTITUTION:A compound expressed by the formula [A is H or CH3; R is OH, 1-6C alkoxy, alkoxyalkoxy, mono- or di-alkylamino or -O-Cat (Cat is organic or inorganic cation)] and 2chloroethyltrimethylammonium chloride are contained in the aimed plant growth regulating composition. Dose of said composition is possible to be considerably reduced by synergism of the both components in case of rice, wheat, barley and trees, etc., and chemical injury is hardly generated even in case of spraying of high concentration and small quantity. In case of lawn, sprout is increased and considerably branched, thus the grass is made to dense and elongation to upper is also inhibited. |
