PYRAZOPHOS Chemical Properties,Uses,Production

Uses

Fungicide.

Uses

Pyrazophos is a systemic fungicide that provides both protective and curative control of various fungal diseases such as powdery mildew (Podosphaera) on apples, stone fruits, bush fruits and strawberries, Erysiphe in cucurbits and tomatoes, Uncinula on vines and leaf blotch (Rhynchosporium) in cereals.

Definition

ChEBI: A member of the class of pyrazolopyrimidines that is the ethyl ester of 2-[(diethoxyphosphorothioyl)oxy]-5-methylpyrazolo[1,5-a]pyrimidine-6-carboxylic acid. A fungicide used to control Erysiphe, Helminthosporium and ital>Rhynchospium in cereals.

Metabolic pathway

Limited information is available to describe the degradation and metabolic fate of pyrazophos. Hydrolytic cleavage of the P-O-pyrazolopyrimidine linkage is the primary metabolic pathway. Oxidative desulfuration of pyrazophos to pyrazophos-oxon is only a minor pathway, observed in the plant metabolism study (Scheme 1).

Degradation

Pyrazophos (1) is hydrolysed in acidic or alkaline solution (PM).
