To assess the effects of fungicides on enlargement of lesion lesions of rice blast and spore formation on the lesions, several fungicides were sprayed to rice plants after the appearance of the lesions. The fungicides used were isoprothilane, EDDP, IBP, kasugamycin, blastcidin-S and ferimzone. All fungicides inhibited lesion enlargement and spore formation. A linear relation was found between days after application of each fungicide and an area of a lesion during a particular period. A linear, quadratice, or exponential equation was fitted to the relation between days after the application and spore formation on a lesion.
