Applications

How It Works

Propetamphos works by inhibiting acetylcholinesterase, an enzyme crucial for the breakdown of acetylcholine in nerve cells. This inhibition causes the accumulation of acetylcholine, disrupting nerve signal transmission and ultimately leading to pest paralysis and death.

• Action Time: Fast-acting with immediate knockdown effect

• Target Pests: Specifically effective against both adult pests and their larvae/eggs, providing extended control

Limitations & Safety Notes

• Toxicity: As an organophosphate, propetamphos can be toxic to humans and animals if misused. Protective gear should be worn during application.

• Environmental Impact: It can be toxic to aquatic organisms, so care should be taken when using near water sources.

• Resistance: Prolonged use of propetamphos on the same pest populations can lead to the development of pest resistance, necessitating resistance management practices such as rotation with other insecticides.

Frequently Asked Questions

Q: Is propetamphos safe to use around pets?
A: When used as directed, propetamphos is generally safe for pets. However, direct exposure should be avoided during application, and pets should be kept away until the product has dried or set.
