Product Overview

Rovral Flo fungicide is a Group 2 fungicide for canola and alfalfa grown for seed. It stops fungi at all stages of development, including spore germination, mycelia growth, and spore production, and fights future resistance problems. Rovral Flo fungicide also supports full rotational flexibility by posing no cropping restrictions the following year. That means reliable, economical protection now, and in the future.

Apply Rovral Flo fungicide at the 20 to 50 per cent bloom stage (ideal staging is 20 to 30 per cent bloom, or four to eight days after flowering). Split-applications can be applied at 20 per cent bloom and then again at 40 to 50 per cent.
