How It Works: Mode of Action
Thiamethoxam affects insect nerve receptors. Optra FS is supplied for seed treatment rather than as the separate Optra25WG product.
-
Seed receives treatment: Measure by the crop’s seed weight using the complete pack instructions.
-
Listed early pests are targeted: The manufacturer describes protection during the tender growth stage.
-
Nerve function is disrupted: Thiamethoxam acts on nicotinic acetylcholine receptors in susceptible insects.
Do not count a different thiamethoxam formulation as a different resistance group. Consider the seed treatment when planning later insecticide choices.

Dosage & Application Guide
Numerical seed-treatment programmes are withheld because published product quantities alone do not establish the complete preparation, coating, handling and sowing process for the current Optra FS pack. The manufacturer’s quantity basis is seed weight, not area or spray-water volume; verify the complete crop-specific process before treatment.
Keep each crop and its listed pest targets separate. The manufacturer describes quantities per kilogram of seed, but no numerical seed-treatment recipe is supplied here. Confirm preparation and the permitted interval between treatment and sowing on the supplied pack.
No water or slurry quantity is assumed. No per-acre, per-litre, tank or seed-batch dose has been calculated. A missing harvest or other interval is not zero; follow all relevant pack restrictions.
Confirm treatment equipment, dilution or slurry preparation, mixing sequence, drying, sowing interval, storage of treated seed and any restrictions before use. Do not use Optra25WG instructions for this FS formulation.
How to Apply: Best Practices
-
Match crop, pest and seed weight: Check the supplied label and measure the seed accurately before selecting its verified crop-specific seed-treatment programme.
-
Use the complete treatment method: Follow the pack’s equipment and preparation directions. Do not invent water or slurry amounts. Avoid highly acidic or alkaline mixtures; this is not permission for other tank partners.
-
Handle treated seed safely: Keep treated seed clearly identified and separate from food, feed and untreated seed. Never use treated seed for food or feed.
-
Follow sowing and disposal precautions: Confirm drying, storage and sowing instructions. Prevent spills and access by children or animals, and dispose of residues and containers as the label directs.
