How It Works: Mode of Action
Optra affects receptors involved in insect nerve signalling. The manufacturer describes systemic movement together with contact and stomach action.
-
Pests encounter treatment: Exposure can occur through contact or feeding on treated plant material.
-
Nerve signalling changes: Thiamethoxam acts on nicotinic acetylcholine receptors.
-
Normal pest activity is disrupted: Follow the exact crop and pest directions rather than assuming a fixed control time.
Switching between thiamethoxam brands is not a change of mode of action. Plan suitable rotations and other pest-management measures.
Target Crops & Pests
The current-hosted Coromandel catalogue lists the following crop and pest pairings for Optra. Confirm the intended use on the supplied label.

Do not extend these directions to other crops or rice pests merely because another thiamethoxam product lists them.
Dosage & Application Guide
Numerical application programmes are withheld because the published product quantities do not establish complete current Optra directions with matching method, treatment conditions, carrier and harvest requirements. Confirm these together on the supplied label before use.
Keep the three crop-and-target programmes distinct: rice stem borer, leaf folder, gall midge and thrips; cotton jassids, aphids and thrips; and cotton whiteflies. Do not transfer quantities or other application requirements between them.
Do not treat an unknown waiting period as zero days. No per-litre or tank dose is derived, and no spray-water quantity is assumed from another brand.
Confirm application route, equipment, crop-stage timing, water volume, repeat limits, re-entry, rain-free interval and harvest requirements on the supplied pack.
How to Apply: Best Practices
-
Identify the pest: Separate cotton whiteflies from jassids, aphids and thrips when checking the label quantity.
-
Check the formulation: Use Optra 25% WG directions, not Optra FS 30% seed-treatment instructions.
-
Prepare only after checking the pack: Follow the exact mixing, application method, equipment and water directions. Do not assume all tank partners are suitable.
-
Plan harvest and entry: Confirm the waiting period and field-entry precautions, and record crop, date, target and amount.
Frequently Asked Questions
What does Optra contain?
Thiamethoxam 25% WG, a water-dispersible-granule insecticide.
Is Optra the same as Optra FS?
No. Optra is 25% WG; Optra FS is a 30% seed-treatment formulation. Do not interchange their rates or methods.
Which rice pests are listed here?
Stem borer, leaf folder, gall midge and thrips, as listed in Coromandel’s current-hosted catalogue. Check the current pack for your intended use.
Does cotton have one quantity for all pests?
No. Coromandel lists a separate quantity for cotton whiteflies rather than the jassid, aphid and thrips programme. Verify each complete programme on the supplied current label; no numerical treatment directions are supplied here.
Can I use a fixed tank dose or harvest interval?
Not from this description. Confirm the crop-specific water, mixing and harvest directions on the current pack; an unconfirmed interval is not zero.
