Abstract
Tricyclazole (5-methyl-1,2,4-triazolo[3,4-b]benzothiazole) is a unique fungicide for control of Pyricularia oryzae on rice. Tricyclazole is systemic in rice and will control rice blast disease in any stage of plant development by a variety of application methods. Tricyclazole protects plants from infection by P. oryzae by preventing penetration of the epidermis by the fungus. The compound acts by inhibiting melanization within the appressorium, thus causing a lack of rigidity in the appressorial wall. Tricyclazole has no apparent effect on spore germination although sporulation is reduced. Tricyclazole is not curative but is protective in its activity.
