The effect of allylamine fungicide terbinafine on the growth to the 10-day old seedling stage, squalene content and sterol content and composition and the sterol 7 reductase of microsome prepared from 72-hour old maize embryos, have been studied. It was found that terbinafine caused progressive inhibition when administered in the 2.5-50 Mew M concentration range. It caused significant increase in squalene content at a concentration of 20 Mew M. Terbinafine significantly decreased the 4-demethyl sterol content of seedlings. Additionally, it caused the accumulation of 5, 7 sterol. It was found to be competitive inhibitor of maize embryos microsomal sterol-7-reductase. Its relative I 50 and apparent Ki was 1 Mew M and 1.3 Mew M respectively.
