How it Works
After application, Revus adheres to the waxy cuticle of treated leaves, becomes rainfast and establishes a barrier to
prevent fungi from taking hold. The fungicide also enters the leaf to provide protection to both sides of the leaf.
Revus also provides anti-germination effects; therefore, disease spores that land on the plant are prevented from
germinating.
