Lara 909 Insecticide (Chlorpyriphos 50% + Cypermethrin 5% EC)

The "505" Formulation: A Dual-Action Powerhouse for Cotton and Paddy.

Lara 909 by Crystal Crop Protection is a broad-spectrum insecticide designed to tackle the toughest pest complexes in Indian agriculture. Known popularly as the "505" mixture, it combines the heavy-hitting power of Chlorpyriphos (Organophosphate) with the rapid knockdown speed of Cypermethrin (Synthetic Pyrethroid). This synergistic blend ensures that pests are stopped immediately upon contact and eliminated through stomach poison action.

Best for: Farmers looking for a cost-effective, single-spray solution to control both chewing pests (like Bollworms) and sucking pests (like Aphids and Jassids) simultaneously.

Why farmers choose itWhy Choose This Product? Key Benefits
  • ⏱️ Instant Knockdown: Cypermethrin acts immediately upon contact, stopping pests from feeding and preventing further crop damage within minutes.
  • ?️ Double Protection: Offers a dual mode of action—Systemic (Stomach) poison to kill internal borers and Contact poison to kill surface pests.
  • ⏳ Long-Lasting Control: The formulation adheres to waxy leaf surfaces, providing residual protection for 10 to 14 days against re-infestation.
  • ?️ Vapor Action (Fumigant): Chlorpyriphos creates a vapor that penetrates dense canopies, reaching pests hidden in curled leaves, cotton bolls, or soil crevices.
  • ? Broad Spectrum: A true "All-in-One" solution that controls the Bollworm complex, Stem Borers, Leaf Folders, and sucking pests in a single spray.

Product scienceHow It Works: Mode of Action

Lara 909 attacks the insect nervous system from two angles, making it nearly impossible for the pest to survive.

  1. Nerve Inhibition (Chlorpyriphos): It inhibits the enzyme Acetylcholinesterase (AChE). This causes a buildup of acetylcholine, leading to continuous nerve firing, tremors, and eventual paralysis.
  2. Sodium Channel Lock (Cypermethrin): It keeps the sodium channels in the nerve cells open. This creates a "shock" effect, causing immediate hyperexcitation and rapid knockdown.
  3. Synergy: The vapor action flushes pests out of hiding, while the contact action kills them instantly.

This dual mechanism helps manage pests that may have developed resistance to single-molecule insecticides.

How to applyDosage & Application Guide

The Golden Rule: Always follow the "Dose per Acre" for accurate results.

How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
CropDose (ml / Acre)Water (L / Acre)Dose (ml / Litre)PHI (Days)
Cotton200 – 400 ml200 – 400 L1.5 – 2 ml15 Days
Paddy (Rice)300 – 375 ml300 – 400 L1.5 – 2 ml21 Days
Vegetables300 – 400 ml300 – 400 L1.5 – 2 ml15-21 Days

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

Useful detailsHow to Apply: Best Practices
  • Timing: Apply at the "Initial Instar" stage (egg hatching) or when pest population reaches the Economic Threshold Level (ETL). For bollworms, 5% damage is the trigger.
  • Mixing: Lara 909 is compatible with most neutral fungicides (like Mancozeb). WARNING: Do NOT mix with alkaline products like Bordeaux mixture or Lime Sulphur, as this reduces efficacy.
  • Coverage: Ensure full coverage of the foliage. For Stem Borers in paddy, direct the nozzle toward the base of the plant.
  • Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during bee foraging hours (mid-day).
