Abstract

Cheyenne wheat was treated with varying concentrations of maleic hydrazide and indoleacetic acid in separate and combined applications. Lower concentrations of maleic hydrazide have an inhibitory effect upon germination of wheat seeds and vegetative growth but a stimulatory effect upon uredial pustule development of the leaf rust fungus (Puccinia recondita Rob. ex Desm.). Higher concentrations of maleic hydrazide further inhibit germination and vegetative growth of the host plant, but also inhibit development of the leaf rust fungus. Indoleacetic acid has a stimulatory effect on vegetative growth of the wheat plant at rather low concentrations. At the same time it tends to suppress the inhibitory action of heavier concentrations of maleic hydrazide on the leaf rust fungus when the two are applied in combined treatments.
