I just sprayed Phyton 35 on my Tropicana cannas to kill some rust. The label indicates that it will be effective for 21 days. How soon after application does Phyton 35 begin working?
A copper fungicide such as Phyton 35 will start working right away. However, keep in mind that this will not correct existing damage; rather, it will prevent further damage from taking place.
