Fig. 4From: Cross-resistance of the pathogenic fungus Alternaria alternata to fungicides with different modes of actionThe multiple regression of the pathogenicity, mean mancozeb tolerance and the mean difenoconazole tolerance in Alternaria alternata populations. The square mesh is the equation fitting plane for the multiple regression analysis. The black stars are data above equation fitting plane, and gray stars are data below equation fitting planeBack to article page
