edifenphos

CHEBI:34735 ·resolve ·ANTIFUNGAL ·EXACT SEEDED

An organic thiophosphate that is the O-ethyl-S,S-diphenyl ester of phosphorodithioic acid. Used to control a variety of fungal diseases on rice including blast, ear blight and stem rot. Edifenphos is moderately toxic to mammals and fish but poses more of a risk to aquatic invertebrates. — ChEBI

Mechanism summary

Mode of action: CELL_MEMBRANE_SYNTHESIS_INHIBITION host shared target — Assigned from ChEBI role CHEBI:83741 (phospholipid biosynthesis inhibitor). ChEBI asserts the role on the compound. The target it names is one the host has too, so the mechanism is true but is not evidence of selectivity — see mode_of_action_target_scope. Not a curator's mechanistic review.
