2 Gray mold Fungicide Resistance Elevate (fenhexamid) - inhibitor of sterol biosynthesis FRAC group 17 Rovral (iprodione) inhibitor of osmoregulation FRAC group 2 Switch (cyprodinil) inhibitor of methionine biosynthesis FRAC group 9 Switch (fludioxonil) inhibitor of osmoregulation FRAC group 12 Pristine (boscalid) inhibitor of respiration FRAC group 7
3 Blueberry Botrytis Sampling 2015 Sampled B. cinerea from 3 blueberry fields in Skagit Co., 1 field in Island Co. and 4 fields in Whatcom Co. in 2015 (n =85) Sampled conventional and low fungicide input fields Field Code County Treatment BC-19-1 Skagit Conventional BC-19-3 Skagit Conventional BC Skagit Low Input BC-22-4 Island Low Input BC Whatcom Conventional BC-19-6 Whatcom Conventional BC-22-8 Whatcom Conventional BC Whatcom Conventional
4 WA Blueberry Botrytis 2015 Fungicide Resistance Fenhexamid Boscalid Cyprodinil Field 1 Field 2 Field 3 Field 4 Field 5 Field 6 Field 7 Field 8 Skagit Whatcom
5 Summary No evidence of resistance to fludioxonil or iprodione in WA or rest of PNW to date Resistance detected to 3 of 5 site-specific fungicides used to control Botrytis in berries some fields have high levels to all 3 Widespread resistance to fenhexamid, boscalid, and cyprodinil in multiple berry crops need to reduce selection Large variation in frequencies of resistance from field to field are Botrytis populations quite local? Clear correlation of fungicide use history to fungicide resistance strong selection for resistance
6 FRAC Group 7 Fungicides (SDHIs) Inhibit succinate dehydrogenase in the mitochondrion ( Boscalid widespread resistance in PNW average freq. ~ 70% Isofetamid ( Kenja, ISK) Adepidyn ( Miravis, Syngenta) Fluopyram ( Luna series, Bayer) Penthiopyrad ( Fontelis, Dupont) Fluxapyroxad ( Xemium, BASF) New FRAC Group 7 Fungicides New SDHI fungicides are claimed by their manufacturers to control most boscalid-resistant strains of Botrytis cinerea Mechanism of boscalid resistance is known mutations in subunits B, C, and D of succinate dehydrogenase abolish binding Efficacy of these new fungicides will depend on which mutations are present in PNW
7 Group 7 EC 50 Values in PNW boscalid adepidyn Frequency Cut-off value for boscalid resistance isofetamid fluopyram penthiopyrad EC 50
8 Cross-Resistance Resistance to Fungicide B Fungicides in the same FRAC group are generally cross-resistant Resistance to Fungicide A
9 Cross resistance to boscalid in PNW Botrytis Fluopyram (5ppm) Isofetamid (1ppm) Boscalid (5ppm) Boscalid (5ppm) Adepidyn (1ppm) Boscalid (5ppm) Penthiopyrad (5ppm) Boscalid (5ppm)
10 Next Steps Screen a larger number of B. cinerea isolates from different berry crops in WA for sensitivity to adepidyn, isofetamid, fluopyram, penthiopyrad, fluxapyroxad, solatenol Relate in vitro sensitivity to field rates of fungicides on fruit establish a threshold for resistance for each fungicide Field trials of new Group 7 fungicides to test efficacy and support registration for use on berries
11 New Products and Resistance Management Strategies for Mummy Berry and Botrytis Alan Schreiber and Tom Walters
12 Mummy berry and botrytis trial #1 Skagit Valley 15 treatments, 6 programs and 8 active ingredients only. Trial location was previously organic. Pressure was moderate not too low, not too high. No resistance Started applications very early end of February. Trial location was adjacent to the organic trial.

26 Some thoughts about mummy berry. A Meteor (iprodione) treatment was effective in Trial 1, but a Rovral (iprodione) treatment was not that effective in Trial 2. Does not make sense. Oso was not very effective in the organic trial but was effective in the conventional trial. Fracture was more effective in the conventional trial than the organic trial. Products that were most effective Meteor, Proline, Propulse, OSO, Luna Tranquility, Indar/Pristine and some program treatments. Topguard was interesting. Group 3 Indar/Orbit/Proline Products that did not work well Captan, Rovral, Torino (not registered on blueberry). Kenja was intermediate first trial against mummy berry.
27 Some thoughts on botrytis Pressure was low, which limits the conclusions we can draw. Products that did not provide a high level of control included Fracture, Topguard (flutriafol), chlorothalonil, the low rate of Oso and the low and intermediate rates of Torino. Products providing better control (remember this is a location without resistance Meteor, Luna Tranquility, Propulse, Proline, Captan, Switch, Pristine and programs that contain these products.
28 We did a botrytis trial on blackberry very high pressure botrytis crop. Trial was in Skagit. Important point resistance to iprodione, cyprodinil, fenhexamid and boscalid at this location. I fear this trial may be emblematic of what could happen in bad botrytis year in fields with fungicide resistance.
