Bioefficacy & Field Studies

Demonstrating real-world effectiveness for agrochemicals and household products.

At IIBAT, we offer comprehensive bioefficacy testing and field trial services to assess the performance of agrochemicals, biopesticides, and household pesticides under laboratory, greenhouse, and real-world field conditions. Our studies are designed to comply with OECD, EPA, FAO, WHO, and CIB&RC guidelines and are critical for product registration, label claims, and resistance monitoring.

Whether you need to prove that your herbicide works in specific climates or that your mosquito repellent meets international standards, our team delivers robust, scientifically validated data for global regulatory submissions.

🌱 Why Bioefficacy Testing Matters

Efficacy is at the heart of product approval and commercial success. Regulatory bodies require demonstrated effectiveness against target organisms under defined conditions. Bioefficacy testing provides the evidence to:

Support product claims (e.g., “Kills 99% of insects”)
Optimize formulations and application rates
Comply with national and international regulations
Monitor pest resistance and adapt strategies

🧪 Our Bioefficacy & Field Testing Services

Our bioefficacy testing and field studies are designed to evaluate the real-world performance of agrochemicals, biopesticides, and household products. These services are essential for product registration, resistance monitoring, and label claim validation across varied agro-climatic conditions.

1. Greenhouse & Growth Chamber Studies

Objective: Controlled environment testing to assess early efficacy of active ingredients or formulations.

Applications:

Herbicide phytotoxicity & weed control
Insecticidal and fungicidal activity
Crop safety evaluations
Soil & foliar application assessments

✅ Ideal for screening candidate compounds before large-scale trials
✅ Precise control of temperature, light, humidity, and soil conditions

2. Multi-Location Field Trials

Objective: Evaluate agrochemical efficacy under realistic agricultural conditions across different geographies.

Capabilities:

Large-scale trials for herbicides, fungicides, insecticides
Multiple crops (e.g., rice, wheat, maize, vegetables, fruit trees)
Regional pest pressure and environmental variation analysis
GLP-compliant data collection and statistical analysis
Resistance pattern documentation

✅ Trials conducted in varied agro-climatic zones in India and abroad
✅ Supports national registration dossiers and global label expansion

3. Household Pesticide Efficacy Testing

Objective: Confirm the effectiveness of consumer-targeted pest control products in simulated and field-like settings.

Tested Products:

Mosquito coils, mats, vaporisers, and sprays
Aerosols and surface disinfectants
Insect repellents (topical or ambient)
Ant and cockroach baits
Rodenticides

Key Endpoints:

Knock-down time (KDT50, KDT90)
Mortality rates
Repellency and protection time
Residual activity on surfaces

✅ Conducted per WHO guidelines and CIB&RC requirements
✅ Custom test arenas and simulated-use environments available

4. Dose-Response & Mode-of-Action Studies

Objective: Understand the relationship between dose and effect, and determine how the active ingredient works biologically.

We provide:

EC₅₀, LC₅₀, and ED₅₀ estimations
Non-target impact assessment
Mechanism of action classification (e.g., acetylcholinesterase inhibition, mitochondrial disruption)
Resistance development tracking

✅ Crucial for resistance management strategies and WHO policy compliance

5. Residue and Persistence Studies

Objective: Assess residue levels of pesticides on crops and environmental surfaces.

Services include:

Sample collection at various intervals post-application
Residue analysis in plant tissue, soil, and water
MRL (Maximum Residue Limit) determination
Pre-harvest interval (PHI) and re-entry interval (REI) support

✅ Conducted under field conditions with validated analytical methods (LC-MS/MS, GC-MS)
