difenoconazole / azoxystrobin (Quadris Top)

For best results, sufficient water volume must be used to provide thorough coverage. Quadris Top Fungicide can be applied by ground or aerial application. Use a minimum of 15 gal/A of water for ground applications. Avoid rates of methylated or ethylated vegetable oil/organosilicone adjuvants over 0.125%.

On V. labrusca, V. labrusca hybrids and other non-viniferea hybrids where sensitivity is not known, the use of Quadris Top Fungicide by itself or in tank mixtures with materials that may increase uptake (adjuvants, foliar fertilizers) may result in leaf burning or other phytotoxic effects.

Quadris Top Fungicide is extremely phytotoxic to certain apple varieties.
