What Is Delegate Insecticide?
Delegate Insecticide is a premium-grade crop protection product manufactured by Dow AgroSciences, now operating as Corteva Agriscience. It contains Spinetoram 11.7% SC (Suspension Concentrate) as its active ingredient — a naturally derived compound from soil bacterium Saccharopolyspora pogona.
It is widely trusted by Indian and global farmers for delivering fast knockdown of sucking and chewing pests with minimal environmental impact. Delegate belongs to IRAC Group 5, making it an excellent rotation partner in resistance management programs.
How Does Delegate Insecticide Work?
Delegate works through two modes of action:
- Contact action: Kills insects directly upon spray contact
- Ingestion/systemic action: Insects feeding on treated plant tissue absorb the toxin
Once inside the insect, Spinetoram activates nicotinic acetylcholine receptors and disrupts GABA-gated ion channels — causing involuntary muscle contractions, paralysis, and death within 24–48 hours.
Delegate Insecticide Uses
Delegate is one of the most versatile insecticides available for modern integrated pest management (IPM). Its uses span a wide range of crops and pest types.
Crop-Wise Uses of Delegate Insecticide
| Crop | Target Pests |
|---|---|
| Cotton | Thrips, spotted bollworm, pink bollworm |
| Chilli & Capsicum | Thrips, fruit borers, leafminers |
| Grapes | Thrips, leafhoppers |
| Mango | Hoppers, leafrollers, tip borers |
| Vegetables (tomato, brinjal, okra) | Leafminers, caterpillars, armyworms |
| Pulses & Legumes | Pod borers, leaf-eating caterpillars |
| Soybean | Whitefly, semi-looper |
Key Pest Management Benefits
- ✅ Rapid pest knockdown within 24–48 hours of application
- ✅ Residual activity for up to 7–10 days post-spray

Delegate Insecticide Content (Active Ingredient & Formulation)
Understanding the formulation content of Delegate is essential for proper dosage calculation and resistance management.
Technical Details
| Parameter | Detail |
|---|---|
| Trade Name | Delegate |
| Active Ingredient | Spinetoram |
| Concentration | 11.7% w/v |
| Formulation Type | SC (Suspension Concentrate) |
| Chemical Group | Spinosyns (IRAC Group 5) |
| Manufacturer | Dow AgroSciences / Corteva Agriscience |
| Mode of Action | Nicotinic acetylcholine receptor activator |
Spinetoram is a semi-synthetic derivative of naturally occurring spinosyns — making Delegate suitable for organic-approved IPM programs in several countries. It degrades quickly in soil and water under UV light, reducing long-term environmental accumulation.
Delegate Insecticide Dose Per Acre
Getting the correct dose per acre is critical for achieving maximum pest control efficacy while avoiding crop phytotoxicity or resistance buildup.
Standard Dose Per Acre
| Crop Type | Delegate Dose Per Acre | Water Volume |
|---|---|---|
| Cotton | 80–100 ml/acre | 200–250 litres |
| Vegetables (tomato, chilli) | 60–80 ml/acre | 150–200 litres |
| Fruits (grapes, mango) | 80–100 ml/acre | 200–300 litres |
| Pulses & Soybeans | 60–80 ml/acre | 150–200 litres |
| High-pest-pressure situations | Up to 100 ml/acre | As required |
Pro Tip: Always use the higher end of the dose range during peak pest infestation or when pest population crosses the Economic Threshold Level (ETL). Do not exceed 2 applications per crop season to prevent resistance.
Delegate Insecticide Dose Per Litre of Water
For farmers using knapsack sprayers or boom sprayers, calculating dose per litre ensures correct dilution and even coverage.
Dose Per Litre (Ready Reckoner)
| Application Method | Delegate per Litre of Water |
|---|---|
| Knapsack/hand sprayer | 0.4–0.6 ml/litre |
| Power sprayer (high volume) | 0.3–0.5 ml/litre |
| Drone application | Consult agronomist; typically 2–3 ml/litre in ultra-low volume |
How to calculate:
If using 80 ml per acre with 200 litres of water per acre: → 80 ÷ 200 = 0.4 ml per litre of water ✅
Always calibrate your sprayer before application and ensure uniform canopy coverage, especially on the underside of leaves where thrips and leafminers tend to reside.
