Tegata - Lambda-Cyhalothrin 9.5% + Thiamethoxam 12.6% ZC - Parijat
Tegata Insecticide by Parijat
Lambda-cyhalothrin 9.5% + Thiamethoxam 12.6% ZC, combining systemic, contact and ingestion activity against
specified crop pests.
Crop fit: Specified pests of cotton, maize, groundnut, soybean, chilli, tea and
tomato.
First application: For sown crops, 30–40 days after sowing, or when the listed
insects begin appearing at the economic threshold. Use the infestation trigger rather than a sowing calendar for
tea.
Application route: Uniform foliar spraying with a knapsack sprayer, not a seed
treatment, soil drench or irrigation application.
Why Choose This Product? Key Benefits
-
🧪 Two ingredients in one premix: Lambda-cyhalothrin and thiamethoxam provide distinct nerve-action components without separately measuring two insecticide
products.
-
🎯 Crop-specific mixed-pest scope: The listed
uses cover selected sucking pests, caterpillars and borers, with each target kept against its own crop.
-
🌿 Plant uptake plus surface exposure: Systemic, contact and ingestion activity contribute to exposure of susceptible pests; even foliage coverage remains important.
-
💧 Combined ZC formulation: Capsule-suspension and suspension-concentrate components are brought together in one formulation, rather than an interchangeable EC or
seed-treatment product.

How It Works: Mode of Action
-
Contact, feeding and uptake expose the pest: The foliar treatment acts through insect contact and ingestion, with systemic uptake
and upward movement in the plant’s xylem contributing to exposure.
-
Lambda-cyhalothrin affects sodium channels: The Group 3A component disturbs the opening and closing of nerve-cell sodium channels,
causing prolonged excitation and loss of coordinated insect activity.
-
Thiamethoxam acts at nerve receptors: The Group 4A component acts at nicotinic acetylcholine receptors, disrupting normal nerve
signalling. The two ingredients act at different sites in susceptible insects.
Both Groups 3A and 4A count in resistance planning. A premix is not resistance-proof, and changing the brand
alone may not change the action groups. No fixed knockdown time, rainfast interval, virus prevention or yield guarantee is
implied.
Target Crops & Pests
| Crop |
Target pests |
|---|---|
| Cotton |
Jassids; aphids; thrips; bollworm |
| Maize |
Aphid; shootfly; stem borer |
| Groundnut |
Leaf hopper; leaf-eating caterpillar |
| Soybean |
Stem fly; semilooper; girdle beetle |
| Chilli |
Thrips; fruit borer |
| Tea |
Thrips; semilooper; tea mosquito bug |
| Tomato |
Thrips; whitefly; fruit borer |
Match both the crop and pest before treatment. Common names such as fruit borer, bollworm and semilooper do not
establish control of every species bearing that name, and a pest listed on one crop is not automatically included on
another.
Dosage & Application Guide
First-Spray Timing, Water Coverage & Repeat Decisions
Use foliar spraying. For sown crops, the first-treatment stage is 30–40 days after sowing, or when the listed
insects begin appearing at the economic threshold level. For tea, use the infestation trigger rather than applying a sowing calendar.
The crop rows use 500 L spray water/ha, approximately 202.34 L/acre, for uniform coverage. Where another treatment is required and
permitted, the stated second-spray spacing is 10–15 days after the first.
These water and timing instructions are not a complete spray recipe. Establish the exact product amount,
crop-specific harvest restriction, maximum applications and re-entry requirements before preparing a tank. Scout again before a repeat
treatment; the spacing is not an instruction to spray automatically or a harvest waiting period.
How to Apply: Best Practices
-
Confirm the crop and active pest: Scout for the listed insects and their relevant stages. Use local crop advice to establish the
economic threshold rather than treating all visible insects or old damage as a reason to spray.
-
Complete the application plan: Keep the crop, target, product quantity, water, first timing and harvest restriction together. Do
not copy the rate of a different lambda-cyhalothrin or thiamethoxam product.
-
Prepare suitable equipment: Use a clean, leak-free, calibrated knapsack sprayer. Check nozzle output and distribution for the
measured area before handling the concentrate.
-
Mix with continuous agitation: Measure the confirmed product quantity with a dedicated measure, add it to a bucket half filled with
water and agitate. Add the remaining recommended water with continuous agitation. Do not mix with bare hands.
-
Cover the foliage evenly: Apply uniformly, avoiding gaps, excessive overlap and drift beyond the crop. Systemic uptake does not
compensate for missed rows or poor spray placement.
-
Keep mixtures and repeats specific: Use any proposed pesticide, adjuvant or fertiliser addition only when both current product
labels permit that combination for the crop. Review pest pressure before any repeat and follow treatment limits and the resistance
plan.
-
Keep application records: Record crop, pest, treatment date and amount. Keep harvest waiting, worker re-entry and repeat-spray
intervals separate when planning later work.
Frequently Asked Questions
1. Does Tegata control every sucking pest or caterpillar?
No. The crop-and-pest combinations define its scope. Tea includes tea mosquito bug, while tomato includes
whitefly; neither entry should be transferred automatically to another crop.
2. What does ZC mean?
It combines capsule-suspension and suspension-concentrate components. EC, SC and seed-treatment products may
have different concentrations and directions, even if they share an active ingredient.
3. When should the first treatment be made?
For sown crops, 30–40 days after sowing, or when the listed insects begin appearing at the economic
threshold. For tea, use the infestation trigger. The economic threshold must be established for the crop and pest; it is not a
universal insect count.
4. Does systemic activity permit a soil drench?
No. Tegata’s stated route here is foliar spraying. Movement inside a plant does not create permission for
seed, soil or irrigation-system use.
5. Do the two action groups remove the need for rotation?
No. Account for both Groups 3A and 4A and use crop-appropriate, effective alternatives with other
pest-management measures. Any tank partner also needs permission under both current product labels.
Safety & Disclaimer
Before you use it: Read the current Tegata label and leaflet before use. Confirm the complete
crop-specific programme and follow protective-equipment, weather, pollinator, harvest, re-entry, first-aid, equipment-cleaning and
disposal directions.
Wear gloves, an apron and a mask, with any further protection required by the pack. Avoid breathing spray
and prevent contact with the mouth, eyes and skin. Do not smoke, drink, eat or chew while handling or spraying. Wash thoroughly
after handling. Bathe properly after application and wash contaminated clothing separately.
Keep the original labelled container closed and secure, away from children, animals, food, feed, water
sources and fire. Prevent drift and contamination of ponds, drains and other water sources by spray, leftovers or washings. Seek
medical help promptly after exposure or illness and take the pack or label; do not improvise medical treatment.
