Corteva Tracer Green Insecticide (Spinosad 45% SC)
The Ultimate Biological Solution for Bollworms, Thrips, and Caterpillars
Tracer Green Insecticide (by Corteva Agriscience) is a revolutionary pest control solution that bridges the gap between biological safety and chemical strength. Powered by Spinosad, a natural ingredient derived from soil bacteria, it offers rapid "knockdown" power against stubborn pests like the American Bollworm and Thrips.

Why Farmers Trust Tracer: It works on pests that have developed resistance to other chemicals. While it is tough on pests, it is derived from nature ("Green Chemistry"), making it a smarter choice for Integrated Pest Management (IPM) and export-quality crops.
Why Choose This Product? Key Benefits
- ⏱️ Stops Damage Instantly: Pests stop feeding within minutes of contact, preventing further crop loss immediately.
- ?️ Kills Resistant Pests: Highly effective against Bollworms and Thrips that survive generic chemical sprays.
- ⏳ Long-Lasting Protection: It absorbs into the leaf (translaminar action), killing hidden pests like leafminers.
- ?️ Rainfast & Stable: Once dried (1-3 hours), it resists washing off and remains effective under sunlight.
- ? Export Friendly: With a short Pre-Harvest Interval (PHI), it ensures your produce is residue-free for the market.

How It Works: Mode of Action
Tracer Green works unlike any other chemical. It attacks the nervous system of the insect in a unique way:
- Contact & Ingestion: The insect touches the spray or eats a treated leaf. Eating the leaf is the fastest way it gets poisoned.
- Over-Excitation: Spinosad binds to the insect's nerve receptors, causing uncontrollable tremors and muscle spasms.
- Paralysis & Death: The pest becomes paralyzed, falls off the plant, and dies within 24 to 72 hours.
Note: Even if the pest takes 2 days to die, it stops damaging your crop within minutes of exposure.

| Chilli / Onion | Thrips, Fruit Borers |
| Red Gram (Pulses) | Pod Borer |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 66 - 88 ml | 200 L | 0.3 - 0.4 ml | 10 Days |
| Chilli | 64 - 80 ml | 200 L | 0.3 - 0.4 ml | 3 Days |
| Red Gram | 50 - 65 ml | 200 - 400 L | 0.25 - 0.3 ml | 47 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply at the first sign of pests (egg hatching or small larvae). Spray in the evening or early morning to avoid harming bees.
- Mixing: Shake the bottle well before use. Avoid mixing with highly alkaline products (like Bordeaux mixture).
- Coverage: Use high water volume (200L per acre) to ensure the entire plant is wet, as ingestion causes the fastest kill.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Tracer Green kill beneficial insects?
Tracer is highly selective. It targets pests like
worms and thrips but has low toxicity towards beneficial predators
like ladybird beetles and lacewings.
2. Can I use this on export crops?
Yes. Tracer is an excellent choice for export crops like
Chilli and Grapes due to its low residue profile and short
Pre-Harvest Interval (PHI).
3. How quickly does it work?
Pests stop feeding within minutes. Complete mortality
usually occurs within 1 to 3 days.
4. Is Tracer organic?
Tracer
is derived from natural sources (Green Chemistry) and
Spinosad is often used in organic farming abroad. However,
check your local certification body regarding the specific
adjuvants in the 45% SC formulation.
5. Why is the label Blue/Yellow if it is
"Green" chemistry?
The
"Green" refers to its eco-friendly origin and
biodegradability. However, because it is a highly
concentrated product (45%), safety regulations classify it as
"Moderately Toxic" to humans if handled improperly.
Always wear protection.
