How It Works: Mode of Action
The two active ingredients affect insect nerve signalling at different sites. Their IRAC classification describes the mechanism, not permission to treat every crop or pest.
-
Chlorpyriphos, Group 1B: An organophosphate acetylcholinesterase inhibitor. It disrupts the normal breakdown of a chemical used in insect nerve signalling.
-
Cypermethrin, Group 3A: A pyrethroid sodium channel modulator that disrupts normal nerve-signal transmission.
-
Plan for both groups: Consider both Groups 1B and 3A when choosing label-approved rotation partners. Changing a brand name alone does not change the mode of action.
Target Crops & Pests
Use only the crop-target combinations on the current supplied label. Do not extend these uses to an unlisted crop or pest.
| Crop |
Target Pest(s) |

| Cotton |

| Rice (paddy) |

Do not use on ber, citrus or tobacco. Indian restrictions prohibit chlorpyriphos use on these crops.
Dosage & Application Guide
Application Requirements
Use one complete crop-specific programme from the supplied pack and authorised AgroStar advice: match the target pest, formulated-product quantity, water volume, spray route, application timing and harvest interval. Do not combine a dose from one source with water or timing from another.
The 100 ml bottle is a sale quantity, not a one-acre dose or a spray-pump recipe. Measure the treatment area and follow the matching product and water instructions. Do not infer a per-litre concentration from bottle size.
Follow the crop-specific interval between the final treatment and harvest, together with separate worker re-entry and repeat-treatment restrictions. Do not assume a zero-day waiting period, immediate re-entry or unlimited sprays.
How to Apply: Best Practices
-
Check the exact product: Match Arex 505, the stated active ingredients, your crop and the intended target pest. Do not substitute directions from another concentration or formulation.
-
Confirm the whole programme: Before spraying, obtain the crop-specific product rate, water volume, timing, repeat limits and waiting periods from the supplied pack and authorised guidance.
-
Measure and mix safely: Use a suitable measuring device and the mixing order on the supplied label. Never mix with bare hands. Keep the product and the spray mixture away from food and drinking water.
-
Use the stated spray equipment: The leaflet lists knapsack, foot, compression, battery and power sprayers fitted with a hollow-cone nozzle. Calibrate equipment for the label’s crop-specific product and water quantities.
-
Protect bees, birds and water: Avoid spraying during bee foraging. Do not use near water bodies, aquaculture, pisciculture or bird habitats. Prevent drift and contaminated washings from reaching these areas.
-
Check mixtures and restrictions: Do not assume compatibility with every pesticide or fertiliser. Use only mixtures allowed by the relevant labels and product-specific advice. A jar test alone does not establish crop safety or legal approval.
The safety data sheet identifies strong oxidisers as materials to avoid. Keep the product away from heat and ignition sources.
Frequently Asked Questions
No. Bottle volume is the sale quantity. Measure the field area and follow the complete crop-specific product rate and water volume on the supplied label.
No. Match the crop and target pest on the supplied label. Do not use Arex 505 on ber, citrus or tobacco.
Do not assume that a shared active ingredient makes the brands, concentrations or application programmes interchangeable. Follow the directions for the exact product and crop.
No blanket tank-mix recommendation applies. Check the current labels and obtain product-specific advice for the exact mixture before use.
No. The pre-harvest interval concerns harvesting after the last treatment; re-entry governs when people may return to the field. Follow both restrictions separately.
