Chemical Class and Triple Mode of Action
Chlorpyriphos belongs to the organophosphate chemical class (IRAC Group 1B - Acetylcholinesterase inhibitors). It acts by inhibiting the vital enzyme acetylcholinesterase (AChE) in insect nerve junctions.
This inhibition leads to the accumulation of acetylcholine at cholinergic synapses, causing continuous nerve firing, spasms, paralysis, and insect mortality. Its unique vapor action provides fumigant knockdown within dense soil pores and crop canopies.
- Triple Action Defense: Operates simultaneously through direct contact, ingestion, and respiratory vapor penetration.
- Dustable Powder (DP): Ready-to-apply dusting formulation eliminating the need for water mixing in rainfed or water-scarce regions.
- Broad Soil & Foliar Range: Highly effective against subterranean cutworms, white grubs, and leaf-chewing caterpillars.
Target Pests and Labeled Crop Systems
Hindol 1.5% DP is registered under CIBRC standards for managing agricultural pests in paddy (rice), pulses (Bengal gram), groundnut, and sugarcane, as well as protecting timber against subterranean termites.
In field crops, it effectively manages paddy stem borers, leaf folders, green leafhoppers, and pod borers in Bengal gram, while soil dusting protects young seedlings against cutworms and subterranean termites.
- Paddy Crop Protection: Controls yellow stem borer, gall midge, and leaf folder during early vegetative growth.
- Pulse Defense: Dusted over Bengal gram to suppress pod borer (Helicoverpa armigera) infestations.
- Soil Application: Applied along furrows during sowing to protect germinating groundnut and cane sets from termites.
Application Guidelines and Safety Protocols
Apply Hindol using a mechanical or rotary hand duster during calm morning or late evening hours to avoid wind drift. Ensure uniform dust distribution across crop rows or soil furrows.
Operators must wear full personal protective equipment including dust masks, protective goggles, and full-sleeve overalls. Store the product in original sealed bags away from livestock fodder and household grain.
- Dusting Timing: Apply when wind velocity is low to prevent drift away from target crops.
- Personal Protection: Avoid inhalation of chemical dust and direct contact with skin or mucous membranes.
- Pre-Harvest Interval (PHI): Observe mandatory safety waiting periods between application and harvest as indicated on the official CIBRC label.

Common questions
What is the technical composition of Hindol insecticide?
Hindol contains Chlorpyriphos 1.5% DP (Dustable Powder), an organophosphate insecticide.
How does Hindol kill insect pests?
It inhibits the acetylcholinesterase enzyme, causing nervous system overstimulation and paralysis through contact, ingestion, and fumigant vapor action.
Can Hindol be used for termite control in soil?
Yes, Hindol 1.5% DP is widely used for furrow dusting and soil treatment to prevent subterranean termite attacks on crops and timber.
