Pyrimethanil is an anilinopyrimidine fungicide used in agriculture to control a wide range of fungal diseases in fruits, vegetables, and ornamental crops.
It works primarily by inhibiting fungal methionine biosynthesis, which prevents spore germination, penetration, and early fungal growth.

It is widely used for diseases such as:

• Botrytis (gray mold)

• Scab

• Alternaria

• Anthracnose

• Leaf spots

• Fruit rots

Pyrimethanil is known for its protective activity, moderate translaminar movement, and its important role in resistance-management programs.
