Impact of tricyclazole and azoxystrobin on growth, sporulation and secondary infection of the rice blast fungus, <i>Magnaporthe oryzae</i>

Abstract

This study presents for the first time detailed azoxystrobin and tricyclazole growth-response curves for M. oryzae mycelium growth and sporulation. Furthermore, high efficacy of tricyclazole towards inhibition of sporulation and secondary infection indicates an additional possible mode of action of this fungicide that is different from inhibition of melanin biosynthesis.
