Decis 100 - Deltamethrin 11% w/w EC - Bayer
Item description
Bayer Decis 100 Deltamethrin 11% w/w EC Insecticide
Decis 100 is Bayer's higher-concentration deltamethrin insecticide, officially described as Deltamethrin 100 EC (11% w/w). It is a non-systemic synthetic pyrethroid that acts by contact and ingestion against susceptible chewing and sucking insects.
Bayer and the Government of India recommendation table list Decis 100 uses in cotton, tomato, okra, rice, chilli, tea and onion. The approved rows cover cotton bollworms; tomato, okra and chilli fruit borers; rice leaf folder, stem borer, whorl maggot and green leaf hopper; and thrips in tea and onion.
Identity correction: This product is not Deltamethrin 10% EC. Bayer and the Government source both identify the formulation as Deltamethrin 11% w/w EC. The trade expression “100 EC” is retained in the brand name.
Why Choose Decis 100? Key Benefits
- Higher-concentration Decis formulation: Bayer presents Decis 100 as the higher-concentration evolution of Decis 2.8.
- Rapid knockdown: Bayer describes a strong knockdown effect against susceptible target pests.
- Contact and ingestion action: The product controls insects that contact treated surfaces or ingest treated plant material.
- Residual surface activity: Bayer attributes residual performance to deltamethrin's physicochemical properties.
- Rain-fastness and low evaporation: Bayer notes low water solubility and low vapour pressure among the formulation's performance characteristics.
- Repellent and anti-feeding effects: These additional effects are listed by Bayer for Decis 100.

How It Works: Mode of Action
- Cuticle affinity: Bayer states that deltamethrin adheres strongly to the insect cuticle because of its high lipophilicity.
- Nerve-action target: After entering the insect, deltamethrin changes sodium-channel kinetics in the nerve axon and disrupts normal impulse transmission.
- Feeding interruption and mortality: The nerve disruption produces knockdown and ultimately mortality in susceptible insects.
Decis 100 belongs to IRAC Group 3A. Avoid treating successive pest generations with Group 3A as the only control method. If another treatment is justified, use a separately applied product from a different effective group only when its own current label covers the identified crop and pest.

Dosage and Application Guide
The golden rule: Match the exact crop and pest row, then follow the current Decis 100 pack. The values below are per hectare and must not be treated as a universal per-acre or per-litre rate.
| Crop and Pest | Formulation (ml/ha) | Water (L/ha) | PHI (days) |
|---|---|---|---|
| Cotton - Bollworms | 125 | 400-600 | 30 |
| Tomato - Fruit borer | 100-125 | 375-500 | 3 |
| Okra - Fruit borer | 100-125 | 375-500 | 3 |
| Rice - Leaf folder | 150-187.5 | 500 | 13 |
| Rice - Stem borer, whorl maggot, green leaf hopper | 150 | 500 | 13 |
| Chilli - Fruit borer | 175 | 500 | 5 |
| Tea - Thrips | 100 | 400 | 15 |
| Onion - Thrips | 150 | 500 | 5 |
PHI = pre-harvest interval. These label-aligned hectare rates are not converted to ml per litre or acre. Use the current physical pack if it differs.
How to Apply: Best Practices
- Identify first: Confirm the crop and pest before deciding whether treatment is necessary.
- Coverage matters: Bayer describes Decis 100 as contact and non-systemic, so use the label-directed water volume and calibrated equipment for even coverage.
- Measure accurately: Use a calibrated measuring device; never estimate an EC dose.
- Avoid drift and runoff: Do not spray in strong wind or allow contamination of food, feed or water.
- Resistance stewardship: Combine monitoring, cultural controls and conservation of beneficial organisms with label-directed insecticide use.
- Safety: Wear every item of personal protective equipment stated on the current pack.
Frequently Asked Questions
1. Is Decis 100 Deltamethrin 10% EC?
No. Bayer and the Government recommendation table identify Decis 100 as Deltamethrin 11% w/w EC.
