Usage:
  Biochemistry: Ergosterol biosynthesis inhibitor, by inhibition of steroid reduction (stero1-△14-reductase) and isomerisation (△8 to △7-isomerase). Mode of action: Systemic fungicide with eradicant action. Absorbed by the leaves and roots, giving some protective action. Uses: Control of Erysiphe graminis in cereals, Mycosphaerella spp. in bananas, Corticium salmonicolor ant Exobasidium vexans in tea, and Oidium heveae in hevea. Mixed with carbendazim to extend spectrum of cereal diseases controlled. Phytotoxicity: Scorch may occur on some winter- wheat varieties under certain climatic conditions.
