PYRAZOPHOS Chemical Properties,Usage,Production
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.
Uses
Pyrazophos is an anticholinesterase pesticide used on fruits and vegetables and can be determined by gas chromatography/mass spectrometry and liquid chromatography with fluorescence detection.
Uses
Fungicide.
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).
Metabolism
Its mode of action is believed to be the inhibition of melanin biosynthesis and the development of appressoria by fungal conidia. Formulation is available as emulsifiable concentrate (EC: 30%). Application rates on Oidium spp. are in the range of 15–30 g a.i./hl.
Degradation
Pyrazophos (1) is hydrolysed in acidic or alkaline solution (PM).
