Prem Shankar Pandey* and Udai Pratap Singh

ABSTRACT

The inhibitory activity of betaine hydrochloride, a quaternary base was evaluated against spore germination of some plant pathogenic fungi. The fungi, Curvularia lunata, Colletotrichum gloeosporioids and Heterosporium sp. were the most sensitive as complete inhibition of germination were observed in all the concentrations (200, 400, 600, 800, 1000 ppm) of the chemical. Similar effects on Alternaria alternata, Curvularia maculans, Helminthosporium echinoclova and Helminthosporium penniseti were found at 600, 800, 1000 ppm and Alternaria brassiae, Colletotrichum sp. and Fusarium udum at 800 and 1000 ppm. However, only 1000 ppm was effective against spore germination of Erysiphe pisi.
