PH-D® FUNGICIDE CONTROLS DISEASE IN ALMONDS, CITRUS, GRAPES, LETTUCE AND MORE
PH-D® is a biological fungicide. But you’d never know it by looking at the trial data. It performs like a conventional fungicide against diseases in a wide variety of crops. In almonds, PH-D is effective against Alternaria and scab early in the season. In grapes, it’s effective against Botrytis bunch rot, summer rot and powdery mildew. As the only FRAC 19 fungicide, PH-D is also a very smart addition to any resistance management program. The biological that exceeds all expectations.
