How It Works
Emamectin benzoate binds to glutamate-gated (and GABA-gated) chloride channels in insect nerve and muscle cells, increasing chloride ion influx. This causes hyperpolarization, leading to paralysis and rapid feeding cessation. Larvae stop feeding soon after exposure and typically die within 2–4 days.
Key Benefits
- Fast feeding stop: Larvae quickly cease feeding after ingestion, minimizing crop damage.
- Potent on caterpillars: Highly effective on bollworms and other Lepidopteran larvae.
- Low use rates: Concentrated formulation designed for efficient field performance.
- Favorable profile when used as directed: Degrades in soil over time and does not bioaccumulate.
Application Guidance
- Timing: Spray at early larval instars and at the first signs of infestation for best results.
- Coverage: Ensure thorough canopy coverage; good deposition improves intake by larvae.
- Water Quality: Use clean water; maintain neutral pH where possible.
- Rotation: Alternate with different IRAC groups to delay resistance development.
- Dosage: Use strictly as per the crop- and pest-specific label/leaflet.
Frequently Asked Questions (FAQs)
- Q1. What pests does KETHRIN control?
- Primarily Lepidopteran caterpillars such as bollworms in cotton. Activity is also reported on some Diptera, Homoptera, Thysanoptera, Coleoptera and mites as per label.
- Q2. How quickly will I see results?
- Feeding stops shortly after ingestion; larvae typically die within 2–4 days.
- Q3. Is it contact or stomach action?
- It acts mainly via stomach action and must be ingested by larvae for maximum efficacy.
- Q4. Which crops can I apply it on?
- Cotton (for bollworms) and vegetables of the mustard family as indicated on the label. Use only on labeled crops.
- Q5. Any tips to prevent resistance?
- Rotate with insecticides from other IRAC groups, avoid repeated back-to-back sprays of the same MOA, and follow local IPM thresholds.
- Q6. What about residues and environmental safety?
- When used as directed, emamectin degrades in soil and does not bioaccumulate. Always follow the label to ensure safe, compliant use.
Note
Follow the product label and local agronomic advice for crop-wise dose, spray volume, and intervals. Use as part of an IPM program.
