ABSTRACT:
L-(d)-lactic acid, the dextrorotatory isomer of lactic acid, is an effective plant growth regulant which exhibits classical growth regulant activity at very low concentrations and dosage rates. It can be employed to beneficially stimulate the growth of all plant varieties and is particularly useful for stimulating the growth of commercial crops. As is the case with other growth regulants, L-lactic acid can also be employed to inhibit the growth of plants when applied at sufficiently high concentrations. Thus, L-lactic acid can be employed to stimulate the growth of desired plants, to stimulate the fruit production of fruit-bearing plants, and to inhibit the growth of undesired vegetation. Novel compositions which comprise mixtures of L-(d)-lactic acid and one or more preservatives which are sufficient to prevent the hydrolytic and/or bacterial decomposition of the active isomer are also disclosed.
