Three chemical fungicide mixtures and one biopesticide mixture were screened for control of the banana leaf spots by in vitro and in vivo experiments.The control efficacies of the three chemical mixtures(myclobutanil+prochloraz.flusilazole+prochloraz and tebuconazole+myclobutanil)were 71.6%to 75.7%,significantly higher than the biopesticide mixture(zhongshengmycin+Bacillus subtilis)in field experiments in two years.
