The efficacy is presented as the percentage reduction in the mycelial growth by each fungicide in comparison to the mycelial growth in the absence of the fungicide, on a scale of 0 to 10, where 0 to 1 = no efficacy 
, 2 to 4 = low efficacy
, 5 to 7 = moderate efficacy 
, and 8 to 10 = high efficacy
.
