Why farmers choose itWhy Choose This Product? Key Benefits
  • ⏱️ Instant Knockdown Power: The Cypermethrin component acts immediately, stopping pests from feeding within minutes of contact to prevent further crop damage.
  • ?️ Triple Action Attack: Works through Contact (touch), Stomach (ingestion), and Vapor (gas) action to kill pests hiding in crevices or on the underside of leaves.
  • Long-Lasting Residual Control: The high load of Chlorpyrifos ensures the chemical stays active on the plant surface, protecting your crop for 10 to 14 days after spraying.
  • ?️ Excellent Rainfastness: The lipophilic (oil-loving) EC formulation sticks well to plant surfaces, resisting wash-off from light rains once dried.
  • ? Cost-Effective Synergy: Controls both bollworms and sucking pests in one go, saving you the cost and labor of mixing two different insecticides.

Product scienceHow It Works: Mode of Action

Nurelle D 505 uses a synergistic approach to attack the insect nervous system from two different angles, making it highly effective even against resistant pests.

  1. Synaptic Disruption (Chlorpyrifos): It inhibits the enzyme Acetylcholinesterase (AChE). This causes nerve signals to fire uncontrollably, leading to paralysis and death.
  2. Nerve Shock (Cypermethrin): It targets the Sodium Channels in the nerve axons, keeping them open. This causes immediate hyperexcitation, tremors, and rapid "knockdown."
  3. Fumigant Reach: The vapor action of Chlorpyrifos penetrates dense crop canopies, killing pests hiding on the underside of leaves or inside leaf folds.

This dual mechanism ensures that if a pest survives the initial shock, the metabolic poison ensures mortality shortly after.

How to applyDosage & Application Guide

The Golden Rule: Always follow the "Dose per Acre" for accurate results. Do not rely solely on "ml per tank" as tank sizes vary.

How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
CropDose (ml / Acre)Water (L / Acre)Dose (ml / Litre)PHI (Days)
Cotton400 ml200 L2 ml15 Days
Paddy (Rice)350 - 400 ml200 L1.7 - 2 ml15 Days
Vegetables400 ml200 L2 ml7 - 14 Days

*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting to ensure residues are safe.

Useful detailsHow to Apply: Best Practices
  • Timing: Apply at the Economic Threshold Level (ETL)—for example, when you see 5% damaged bolls or 1-2 larvae per plant. Avoid spraying during peak flowering to protect bees.
  • Mixing: Fill the spray tank half with water, add the required dose of Nurelle D 505, and stir well before adding the rest of the water. Do not mix with highly alkaline products like Bordeaux mixture.
  • Coverage: Use a knapsack or power sprayer with a fine nozzle. Ensure thorough coverage of the foliage, as the contact action requires the chemical to touch the pest.
  • Safety: This is a Class II toxic product. Always wear full PPE (gloves, mask, goggles, boots). Do not inhale the spray mist. Wash hands and face thoroughly with soap after use.
