Pyrimethanil is a chemical compound from the group of the anilino-pyrimidines . It is one of the AP fungicides that work by inhibiting methionine synthase .
Extraction and presentation
Pyrimethanil can be obtained by reacting 4,6-dimethyl-2-methyl-sulfonylpyrimidine with formanilide and hydrochloric acid .
Admission
In 2006 the EU Commission decided to include pyrimethanil for use as a fungicide in the list of active ingredients permitted for plant protection products. The production-related contamination of pyrimethanil with cyanamide was classified as questionable, the cyanamide content must not exceed 0.5 g / kg.
In Germany, Austria and Switzerland, plant protection products with this active ingredient are approved.
