Organophosphate Insecticide
PROTHIOFOS 50% EW
An Emulsion in Water (EW) formulation of an organophosphate insecticide. It provides broad-spectrum control through contact and stomach action, featuring reduced odor and an improved safety profile compared to traditional EC formulations, with excellent residual activity.
Active: Prothiofos
Formulation: EW (Emulsion in Water)
Action: Contact & Stomach
Product Information
Mode of Action
Prothiofos inhibits the acetylcholinesterase enzyme, preventing the breakdown of acetylcholine at nerve synapses. This accumulation causes continuous nerve stimulation, leading to tremors, paralysis, and eventual death of the target pest.
Target Pests
- Bollworms (Helicoverpa armigera, Pectinophora gossypiella)
- Aphids
- Whiteflies (Bemisia tabaci)
- Stem borers (Chilo spp.)
- Scale insects
- Thrips
Key Benefits
The EW formulation uses water as the base solvent instead of petroleum oils, resulting in less odor, reduced phytotoxicity risk, and safer handling.
