Pyrimethanil химические свойства, назначение, производство
Химические свойства
Pyrimethanil is a white to light yellow crystalline powder which is sparingly soluble in water but soluble in most organic solvents. Commercial product is available as a brown emulsifiable concentrate.
Использование
Pyrimethanil is a broad spectrum anilino-pyrimidine foliar fungicide. Pyrimethanil functions by inhibiting the biosynthesis of methionine in Botrytis cinerea.
Подготовка
Pyrimethanil is produced by reaction of 2-bromo-4,6-dimethylpyrimidine with aniline.
Определение
ChEBI: Pyrimethanil is a member of the class of aminopyrimidines that is N-phenylpyrimidin-2-amine carrying two additional methyl substituents at positions 4 and 6. A fungicide used to control grey mould on fruit, vegetables and ornamentals as well as leaf scab on pome fruit. Also commonly employed to control Botrytis cinerea throughout the winemaking process in grapes, must, fermenting must and wine. It has a role as an aryl hydrocarbon receptor agonist, an environmental contaminant, a xenobiotic and an antifungal agrochemical. It is an aminopyrimidine, a secondary amino compound and an anilinopyrimidine fungicide.
Общее описание
Pyrimethanil is an anilino-pyrimidine, broad spectrum fungicide primarily used for the control of gray mould and leaf scab on fruits, vegetables and ornamentals. Its mode of action involves inhibition of the secretion of hydrolytic enzymes by the fungi during the infection process, thus stopping the further development of the disease.
Сельскохозяйственное использование
Fungicide: Used on grapes, strawberries, tomatoes, onions, beans, cucumbers, eggplant, and ornamental.

Метаболический путь
Limited data are available in the open literature. Information presented in
this summary is abstracted from the data evaluation published by the
Pesticide Safety Directorate (PSD, 1995). Hydroxylation at the methyl,
phenyl or pyrimidine moiety is the primary metabolic pathway of pyrimethanil
in soil, plants and animals. Cleavage of the aniho-pyrimidine
linkage was observed as a minor metabolic reaction. The formation of
nitro- analogues of pyrimethanil is a novel nitration reaction observed in
the soil metabolism study (Scheme 1).
