  1. a Resistance levels of procymidone resistant isolates from strawberry. LR and MR represent low and moderate resistance, respectively; b EC50 = fungicide concentration resulting in inhibition of 50% mycelium growth rate; c RF = Resistance Factor, it was calculated by dividing the EC50 value of the resistant isolate by the mean EC50 value of the sensitive isolates; d S=Sensitive, R = Resistant. Discriminatory dose (a concentration of fungicide that fully inhibits mycelium growth of the sensitive isolates) used for sensitivity was 10, 5, 5, or 1 (μg/mL) for carbendazim, dimethachlon, iprodione, or fludioxonil, respectively; e Sensitivity of carbendazim to ZoxR isolates; f Sensitivity of dimethachlon, fludioxonil and iprodione to ProR isolates
