Mode of action & use

Mode of action

Inhibits ribosomal RNA synthesis (RNA polymerase I) in oomycetes, with the same activity as metalaxyl at about half the rate.

Systemic: taken up and moved within the plant.

Typical targets and crops

Pythium, Phytophthora and downy mildews in seed treatments, soil and foliar uses, usually in mixtures with fludioxonil, mancozeb or other partners.

Resistance management · FRAC 4

Phenylamides carry a high resistance risk in oomycetes. Use them preventively, in pre-mixtures with a partner fungicide from another group, and keep within the label limit of applications per season.

This is general information on the active ingredient. Registered crops, targets, rates and pre-harvest intervals follow the label approved in each market.
