OSO 5%SC FUNGICIDE (Polyoxin D Zinc salt) by Certis

OSO 5%SC FUNGICIDE (Polyoxin D Zinc salt) by Certis. RESISTANCE MANAGEMENT RECOMMENDATIONS OSO 5%SC Fungicide contains a fungicide classified in FRAC target site of action Group 19. Fungal isolates with acquired resistance to Group 19 may eventually dominate the fungal population if Group 19 fungicides are used repeatedly in the same field or in successive years as the primary method of control for targeted species.

This may result in partial or total loss of control of those species by OSO 5%SC Fungicide or other Group 19 Fungicides. The following actions may prevent or delay fungicide resistance. Avoid consecutive use of OSO 5%SC Fungicide or other Group 19 fungicides against the same pathogens.

Use tank-mixes or premixes with fungicides from different target site of action Groups. Do this only with products that are registered for the same use and are effective at the tank mix or premix rate against the target pathogen(s). Use fungicides as part of a comprehensive Integrated Pest Management (IPM) program. Monitor treated fungal populations for loss of field efficacy. Contact your local extension specialist, certified crop advisor, and/or manufacture representative for fungicide resistance management and/or IPM recommendations for specific crops and resistant pathogens.
