How does penconazole work?

Penconazole is a triazole endogenous fungicide, which can be quickly absorbed and conducted by plants, and has good protective and therapeutic effects.

The main mechanism of action of penconazole is a sterol demethylation inhibitor, which destroys and prevents the biosynthesis of ergosterol, an important component of the bacterial cell membrane, resulting in the failure of the cell membrane to form and the death of the bacteria.

What are the benefits of using penconazole?

Penconazole is a systemic fungicide with protective and curative action. Absorbed by the leaves, with translocation acropetally. Penconazole can be used to control powdery mildew, pome fruit scab, and other pathogenic diseases on vines, pome fruit, stone fruit, ornamentls, hops, and vegetables.

Its holding period can be up to 15 days, and has little inhibitory effect on crops. It can be used as a single or compound agent.
