Unlock the power of "Green Chemistry" with Delegate® by Corteva Agriscience—the ultimate solution for controlling tough chewing and sucking pests in Cotton, Chilli, and Maize.
Formulated with the award-winning active ingredient Spinetoram 11.7% SC, Delegate bridges the gap between biological safety and potent synthetic efficacy. It is specifically designed to tackle pests that have developed resistance to older chemicals, making it the industry standard for managing Thrips, Fall Armyworm, and Fruit Borers.

Why Choose This Product? Key Benefits
- ⏱️Rapid "Stop-Feeding" Action: Pests stop eating your crop within minutes of contact or ingestion, preventing further economic damage immediately.
- ?️Long-Lasting Residual Control: One spray provides robust protection for 12 to 14 days, reducing the need for frequent re-sprays and saving labor costs.
- ⏳Short Pre-Harvest Interval (PHI): Safe to use on crops like Green Chilli just 7 days before harvest, ensuring residue-free produce for the market.
- ?️Excellent Rainfastness: The formulation binds quickly to the leaf surface and resists wash-off from rain after just 2 hours.
- ?Translaminar & Eco-Friendly: Penetrates leaf tissues to kill hidden pests (like thrips) and is safe for beneficial insects once the spray has dried.

How It Works: Mode of Action
Delegate® operates differently from traditional chemicals, making it a powerful tool for resistance management.
- Unique Binding: Spinetoram binds to a unique allosteric site on the insect's nervous system (nAChR), distinct from where neonicotinoids bind.
- Hyperexcitation: This binding causes the nerve channels to lock open, leading to uncontrollable nerve firing and muscle spasms.
- Rapid Paralysis: The insect suffers from metabolic exhaustion, stops feeding immediately, becomes paralyzed, and dies within 24 hours.
Because it targets a unique site, Delegate controls pests that are resistant to other chemical groups like pyrethroids and organophosphates.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Thrips, Spotted Bollworm, Pink Bollworm, Tobacco Cutworm (Spodoptera) |
| Chilli | Thrips (Scirtothrips dorsalis), Fruit Borer (Helicoverpa), Black Thrips |
| Maize (Corn) | Fall Armyworm (Spodoptera frugiperda) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Do not cut corners on water volume.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 180 ml | 200 L | 0.9 ml | 30 |
| Chilli | 180 ml | 200 L | 0.9 ml | 7 |
| Soybean / Corn | 180 ml | 200 L | 0.9 ml | 30 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting to ensure food safety.
How to Apply: Best Practices
- Timing: Apply at the first sign of pest incidence (Economic Threshold Level) or when larvae are small (instars 1-3).
- Mixing: Fill the spray tank half with water, add the required dose of Delegate, mix well, and then fill the rest. Do not mix with highly alkaline substances.
- Coverage: Ensure thorough coverage of the foliage, especially the whorls in Maize and the undersides of leaves in Cotton/Chilli.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray when bees are actively foraging.
Frequently Asked Questions
1. Does Delegate kill Fall Armyworm?
Yes, Delegate is highly effective against Fall Armyworm (FAW) in Maize, especially when sprayed into the whorl during early larval stages.
2. Is it safe for Honey Bees?
Delegate is toxic to bees when wet. However, once the spray dries (usually within 3 hours), it is safe for foraging bees. Spray in the late evening to protect pollinators.
3. What is the rainfastness of Delegate?
It is rainfast within 2 hours of application. Light rain after this period will not wash away the efficacy.
4. Can I use it on Black Thrips in Chilli?
Yes, Delegate is currently one of the most effective molecules for controlling the invasive Black Thrips (Thrips parvispinus) in Chilli.
5. What is the dose for a 15 Liter pump?
At the standard rate of 0.9 ml/L, you should use approximately 13.5 ml to 15 ml of Delegate per 15-liter backpack sprayer.
