| Hazard Information | Back Directory | [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). | [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). |
