“…Acquiring a fungicide resistance linked to a high fitness cost is a clear disadvantage for the fungal strain, as it is counter selected in absence of the corresponding fungicide from a mixed population with sensitive and resistant strains. In natural grey mould populations, this seems to be the case for the phenylpyrrol fungicides for which no (or only few) specifically resistant strains were detected up to now (Leroux et al, 2002;Moyano et al, 2004). The efficacy of such fungicides can be maintained over long periods.…”

“…Resistance to recently introduced fungicides, such as anilino-pyrimidines (APs), phenylpyrroles (PPs) and sterol biosynthesis inhibitors class III (SBIs-III; hydroxyanilides), has also been reported (Leroux et al 2002;Moyano et al, 2004;Weber, 2010). Moreover, field resistance to novel succinate dehydrogenase inhibitor (SDHI) fungicides was detected soon after their introduction (Bardas et al, 2010).…”

were sensitive to all fungicides tested; from north to south, the frequency of sensitive isolates in the regions of Valparaiso, Metropolitana and O'Higgins ranged from 48.15% to 21.1% and 5.88%, respectively. Four hundred and twenty isolates (79%) showed resistance to single or multiple fungicides, 134 (25.4%) were simultaneously resistant to azoxystrobin and pyrimethanil. No fludioxonil-resistant isolates were found, indicating that fludioxonil has great potential for gray mold control in table grapes in Chile. From sixty randomly selected B. cinerea isolates, only the azoxystrobin-resistant isolates carried the G143A point mutation; according to the cytochrome b (cyt b) gene structure, the third intron Bcbi-143/144 was only detected in the azoxystrobin-sensitive isolates. The H272R and H272Y point mutations in the succinate dehydrogenase subunit B (sdhB) gene were associated only with the boscalid-resistant isolates. The F412S and F412V point mutations were found in the sequenced erg27 gene of randomly selected fenhexamid-resistant isolates. These results contribute to the knowledge of B. cinerea fungicide resistance for table grape vine crops in Central Chile, particularly for the development of multiple-resistance and the associated resistance mechanisms of azoxystrobin, boscalid and fenhexamid-resistant isolate populations. Antiresistance strategies are discussed in a general manner.

“…However, high levels of MBC, iprodione, QoI, boscalid and anilinopyrimidine resistance have been reported for Botrytis from a range of other vegetable crops (Moyano et al 2004, Myresiotis et al 2007), as has the very rare occurrence or entire absence of resistance to fenhexamid and fludioxonil (Myresiotis et al 2007).…”

In 2010-2012, a total of 309 isolates of Botrytis cinerea from 23 lettuce fields in Northern Germany was examined for sensitivity to seven fungicides with specific modes of action. Resistance against the frequently used compounds boscalid (45.0% of all isolates), iprodione (37.2%) and quinone-outside inhibitors (strobilurins, 56.3%) was the most common. Isolates combining resistance to two or all three of these fungicides were more frequent than those showing resistance against only one. Strains with cyprodinil (31.4%) or thiophanate-methyl (11.6%) resistance were also observed in the majority of fields. In contrast, resistance against fludioxonil (1 isolate) and fenhexamid (3 isolates) was rare. The abundance of B. cinerea strains with multiple resistance to several currently used fungicides has implications for future lettuce crop management which are discussed.Abbrevations: HR = high resistance, MBC = methyl benzimidazole carbamate, MEA = malt extract agar, MR = moderate resistance, PDA = potato dextrose agar, QoI = quinone outside inhibitor, s = reduced sensitivity, SA = sucrose agar, ss = high sensitivity, TWA = tap water agar, YEA = yeast extract agar
