How It Works: Mode of Action
Lara-909 combines chlorpyrifos and cypermethrin. Both affect insect nerves, but at different points.
- Exposure: Susceptible insects contact the product or ingest treated material.
- Nerve disruption: Chlorpyrifos prevents normal resetting of nerve signals; cypermethrin disrupts their transmission.
- Pest control: Loss of normal nerve function can cause paralysis and death.
Use suitable products from different mode-of-action groups in rotation. Changing only the brand name does not change the mode of action.

Dosage & Application Guide
Water and PHI marked † are general CIBRC guidance for this formulation, not a Lara-909 label. The brand dose needs confirmation; this is not a complete application programme.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | See note* | Approx. 202.3–404.7† 500–1000 L/ha |
See note* | 15† |
Confirm the cotton quantity before mixing. General water and waiting-period figures do not replace the current label.
*Confirm the cotton product quantity on your current pack before use. The published brand range and the general formulation rate do not agree at the lower end; do not select a lower quantity from this page.
The CIBRC formulation reference is 1,000 ml/ha (approx. 404.7 ml/acre), 500–1,000 L/ha water and a 15-day PHI. It does not establish a Lara-909 application method or timing.
No per-litre or tank rate is calculated. Confirm application method, timing and re-entry interval on the supplied label. PHI means the minimum time between last treatment and harvest.
How to Apply: Best Practices
- Identify the pest: Use only for cotton pests listed on your current label.
- Resolve the quantity: Confirm the product dose before preparing a mixture.
- Confirm the method: Check the label application route, water, timing and any repeat limit.
- Plan access and harvest: Confirm re-entry and harvest intervals for the supplied product.
- Avoid assumed mixtures: Do not add another pesticide or adjuvant without label support.
Frequently Asked Questions
What is Lara-909 used for?The manufacturer lists cotton aphids, jassids, thrips, whiteflies and the bollworm complex.
Can I use it on rice or vegetables?Those crops are not included in the current Lara-909 recommendation shown here. A use for the same ingredients under another brand is not permission.
Why is the cotton dose not shown as a working recommendation?The published brand range and formulation reference differ. Confirm the current Lara-909 pack quantity before use rather than guessing.
Does 15 days always apply before harvest?The 15-day figure is a general formulation reference. Confirm the actual Lara-909 label interval and any buyer residue requirements.
Can I calculate a tank dose or mix another product?No tank recipe or tank mixture is recommended here. Follow the supplied label and confirm the application method first.
