Seven foliar sprays of Oso (Polyyoxin D Zinc) 6.5 fl. oz/A + Zivion (Natamycin) 1 gal/A, Oso 13.5 fl. oz/A, YSY (Confidential) 1.5 lb/A, and YSY 1.5 lb/A + OSO 13.5 fl. oz/A applied at a weekly interval on strawberry cultivar ‘Fronteras’. Miravis Prime (Pydiflumetofen +Fludioxonil) 14 fl. oz/A was alternated with Captan (Captan) 3 lb/A as a standard control. Only standard control significantly reduced post-harvest Botrytis fruit rot incidence compared to non-treated control. No phytotoxicity was found in any treatment.

13 sprays of Oso (Polyyoxin D Zinc) 13.5 fl. oz/A + Zivion (Natamycin) 64 fl. oz/A, Oso 13.5 fl. oz/A, and YSY (Confidential) 1.3 lb/A applied at a weekly interval on strawberry Sensation ‘Florida127’. Miravis Prime (Pydiflumetofen +Fludioxonil) 13.4 fl. oz/A was alternated with Captan Gold (Captan) 1.9 lb/A as standard control.
