What Is Parathion?
Parathion, an organophosphate pesticide, known for its effectiveness against various agricultural pests, is characterized by its strong insecticidal activity. Despite its efficacy, parathion’s significant toxicity to humans and environmental hazards have led to its prohibition as a pesticide under various regulations.
Uses of Parathion
Previously used across various crops for pest control, parathion’s use has been curtailed due to its high toxicity levels. It was effective against pests such as psyllids and water bugs but is now largely restricted to specific non-agricultural applications and as a reference substance in pesticide residue analysis.
