Usage

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).
