From 2004 to 2006, 213 isolates of Botrytis cinerea never exposed to QO center inhibitors (QOIs) were collected to determine the baseline sensitivity to azoxystrobin. In the absence of salicylhydroxamic acid (SHAM), the mean EC50 values were 10.49 ± 13.12 and 0.36 ± 0.48 mg l−1 for inhibiting mycelial growth and conidium germination, respectively. In the presence of SHAM, the mean EC50 values were 2.24 ± 1.29 and 0.22 ± 0.11 mg l−1. In 2010, five azoxystrobin-resistant isolates were detected… CONTINUE READING
