How It Works: Mode of Action
Chlorpyrifos is an organophosphate insecticide that inhibits acetylcholinesterase. It disrupts normal nerve signalling in susceptible insects and belongs to IRAC Group 1B.
- Enzyme action: Inhibits acetylcholinesterase, an enzyme involved in ending nerve signals.
- Nerve disruption: Interferes with normal insect nerve function.
- Use selection: Crop sprays, seed treatments, soil treatments and specialist termite work require separate label programmes.
A product’s mode of action does not establish a use on an unlisted crop or guarantee control of resistant pests. Follow a suitable resistance-management programme.
Target Crops & Pests
The grouped table keeps every crop and target named. Branded-leaflet uses are distinguished from extra manufacturer-website listings that require confirmation on the supplied pack. Prohibited ber, citrus and tobacco uses are excluded.
| Crop | Target Pest(s) |
|---|---|
| Cereals |
|
| Cotton |
|
| Pulses |
|
| Oilseeds |
|
| Vegetables |
|
| Apple |
|
| Tea |
|
| Sugarcane |
|
| Non-crop uses |

Do not use chlorpyrifos on ber, citrus or tobacco, even if an older leaflet or retailer lists them. Website-only entries are not complete application recommendations. Buildings and forestry require specialist, site-specific directions, not a crop spray programme.
Dosage & Application Guide
Acre quantities below are approximate conversions of the source hectare values; seed quantities retain their original mL/kg basis. Match each row to the exact crop and pest. Do not treat area-based or seed-treatment quantities as tank concentrations.

Programme map and original quantities: Spray A is paddy hispa, stem borer and gall midge, plus cotton aphids, bollworms, whiteflies, grey weevil and jassids, at 1,250 mL/ha. Spray B is barley corn leaf aphid and paddy leaf roller at 1,875 mL/ha. Spray C is groundnut aphids and brinjal shoot and fruit borer at 1,000 mL/ha. Tea scale insects and red slug caterpillar use 750 mL/ha. Other sprays are cotton cutworm at 3.75 L/ha (about 1.52 L/acre), cabbage diamondback moth at 2 L/ha (about 0.81 L/acre) and onion root grub at 5 L/ha (about 2.02 L/acre), in that order. Original water volume for these sprays is 500–1,000 L/ha.
Seed quantities map to wheat 3–4 mL/kg, barley 4–6 mL/kg and gram 15–30 mL/kg seed. Original soil quantities are wheat 2–3 L/ha and the website-listed sugarcane programme at 6.25 L/ha, which needs matching-pack confirmation. No water quantity or complete preparation programme is established here for seed or soil treatment. No numerical PHI is given in the retrieved leaflet; confirm it for each crop. The leaflet states 48-hour re-entry.
Cotton pink-bollworm and apple-aphid quantities need clarification. The website-only paddy whorl-maggot, beans, gram cutworm, groundnut root-grub, mustard and sugarcane black-bug uses also need their complete matching-label programme. Do not prepare a building or forestry treatment from the crop table. Repeats, maximum applications and mixtures remain label-specific.
How to Apply: Best Practices
- Check legality and identity: Confirm the exact pack, crop and target. Do not treat ber, citrus or tobacco.
- Choose the correct method: Keep crop sprays, seed treatment, soil treatment and specialist termite operations separate. Confirm any website-only use on the supplied label.
- Prepare only a complete programme: Resolve product quantity, water, equipment, protective measures and PHI before starting. The leaflet identifies knapsack or stirrup-pump high-volume spraying and motorised low-volume equipment; do not transfer high-volume dilution to a low-volume method.
- Protect people and wildlife: Observe the 48-hour leaflet re-entry period and any stricter supplied restrictions. Avoid exposure of bees, fish, livestock, birds and wildlife; follow the full label’s environmental precautions.
Frequently Asked Questions
What does Kri-Shan contain?Chlorpyrifos 20% EC, an organophosphate insecticide in IRAC Group 1B.
Which listed crops must not be treated?Ber, citrus and tobacco are prohibited chlorpyrifos uses. Current restrictions override older manufacturer or retailer listings.

What does a blank harvest interval mean?It does not mean immediate harvest or zero days. Confirm the current crop-specific PHI on the supplied pack before applying.
Can the crop recipe be used for building termites?No. Building and forestry treatments require their own complete specialist label and site-specific directions. No DIY structural treatment recipe is provided here.
