Useful:

• Chemical Classes: Pesticides -> Fungicides
• Canonical SMILES: CC1=CC(=NC(=N1)NC2=CC=CC=C2)C
• Uses: Pyrimethanil is a broad spectrum anilino-pyrimidine foliar fungicide. Pyrimethanil functions by inhibiting the biosynthesis of methionine in Botrytis cinerea. Pyrimethanil provides both protective and curative control of fungal diseases in pome fruits (leaf scab caused by Venturiu inaequalis), vines, fruits, vegetables and ornamentals (grey mould)
