The efficacy of tricyclazole, prochloraz and their mixture (triclazole:prochloraz at 2:1, 4:1, 7:1 and 9:1) was investigated against rice blast (M. grisea) in vivo. The 4:1 mixture of tricyclazole and prochloraz had the best control effect against M. grisea. The synergistic ration of the mixture was 2.28. The high control effect was due to inhibitory effect on spore formation and hyphal growth, with EC50 value of 0.236 and 0.346 micro g/ml, respectively.
