Novel Insecticide
PYRIDALYL 10% EC
A novel insecticide with a unique mode of action, highly effective against lepidopteran pests. It shows excellent activity on populations resistant to other chemical classes and has a favorable toxicological and environmental profile, making it safe for beneficial insects.
Active: Pyridalyl
Formulation: EC (Emulsifiable Concentrate)
Action: Contact & Stomach
Product Information
Mode of Action
Pyridalyl acts on intracellular calcium channels and ryanodine receptors in muscle cells, causing an uncontrolled release of calcium. [Image of intracellular calcium release in muscle cells] This leads to muscle contraction, cessation of feeding, paralysis, and death. It acts effectively via both contact and stomach ingestion.
Target Pests
- Bollworms (Helicoverpa armigera, Pectinophora gossypiella)
- Fruit borers (Helicoverpa armigera)
- Diamondback moth (Plutella xylostella)
- Leaf folders (Cnaphalocrocis medinalis)
- Fruit and shoot borer (Leucinodes orbonalis)
Key Benefits
Unique chemistry (unclassified group) makes it an excellent rotation partner for managing resistance in lepidopteran pests.
Recommended Dosage
| Crops | Target Pest | Dosage / Ha (ml) | Formulation (ml) |
|---|---|---|---|
| Cotton | Bollworms | 750 – 1000 | 750 – 1000 |
| Vegetables | Fruit borers, DBM | 600 – 800 | 600 – 800 |
| Rice | Leaf folders, Stem borers | 500 – 750 | 500 – 750 |
| Fruits | Fruit borers | 800 – 1000 | 800 – 1000 |
Dosage Note: Use higher rates (up to 1000 ml/ha) for high pest pressure or larger canopy crops like Cotton and Fruits.
Application Instructions
1. Timing
Apply when larvae are in the early instars (stages 1-3). The product causes feeding cessation rapidly, but total mortality may take a few days.
2. Selectivity
Pyridalyl is highly selective, meaning it targets pests while being safe for most beneficial insects and pollinators, making it ideal for IPM programs.
Safety Precautions
Environmental Profile: Safe for beneficial insects. However, avoid application near water bodies to protect aquatic life.
Handling: Wear standard protective clothing during mixing and application. Ensure good spray coverage as it acts by contact and ingestion.
