Key benefits
Why growers choose Combi 505 for trusted Chlorpyriphos 50% + Cypermethrin 5% EC performance.
Dual chemistry for practical field pressure
Combi 505 combines organophosphate and pyrethroid action to support broad-spectrum control in mixed pest situations.
Fast action with dependable follow-through
The formulation supports quick knockdown and sustained control when applied early at threshold stage.
Easy-to-handle EC spray format
Its emulsifiable concentrate profile mixes smoothly in routine knapsack and power-sprayer operations.
Clear dose discipline
Recommended use of 25 ml per pump helps spray teams maintain consistency and avoid under-dosing.
Useful across multiple commercial crops
Commonly integrated in cotton, paddy, groundnut, sugarcane, vegetable and pulse crop programs.
Supports resistance-management plans
Works best inside rotation-based pest management with scouting, ETL checks and responsible spray intervals.
Target pests
Built for practical field conditions where mixed pest complexes impact crop health and productivity.
Bollworms
Used in programs where larval feeding pressure threatens yield and boll quality.
Stem borers
Supports action during early borer incidence across cereal and related crops.
Leaf folders
Helps reduce foliage damage where folded-leaf feeding starts spreading rapidly.
Thrips
Useful in mixed sucking pest windows where crop stress can rise quickly.
Aphids and whiteflies
Fits broad-spectrum schedules when sap-feeding pests cross field thresholds.
Cutworms
Can be included where cutworm attack affects stand establishment and vigor.
Crops & applications
Field-ready application guidance for Combi 505.
Cotton
Applied in ETL-based windows for combined chewing and sucking pest pressure.
Paddy
Included in practical schedules where stem borer and leaf-folder concerns are active.
Groundnut and pulses

Mode of action
How Chlorpyriphos 50% + Cypermethrin 5% EC performs in practical application.
Chlorpyriphos pathway
Chlorpyriphos inhibits acetylcholinesterase in insects, which disrupts nerve impulse transmission and feeding behavior.
Cypermethrin pathway
Cypermethrin targets sodium channels in nerve membranes, leading to hyperexcitation, paralysis and pest mortality.
Combined field impact
The dual mechanism helps handle mixed infestations where both chewing and sucking pests are present in the same crop block.
Best outcomes with timing discipline
Apply at early infestation windows with proper coverage and interval planning for cleaner, more stable results.
Usage & safety guidelines
Follow this checklist for safer handling and better field consistency.
Spray discipline PPE and stewardship
Usage best practices
Measure right, mix clean, spray with coverage.
Wear PPE before handling
Use gloves, mask, goggles and covered clothing while measuring, mixing and spraying.
Measure dose accurately
Use 25 ml per pump and avoid overdose to reduce residue risk and crop stress.
Pre-mix before tank filling
Prepare a small slurry first, then add to tank and top up with water under agitation.
Safety and responsibility
Follow label, advisory and responsible disposal rules.
Spray in suitable weather
Avoid high wind, peak heat and rain-prone windows to reduce drift and runoff.
Observe re-entry interval
Allow at least 24 hours before re-entry, and use protective gear when required.
Store and dispose responsibly
Keep away from food/feed and dispose containers as per label and local regulations.
