Keefun Insecticide (Tolfenpyrad 15% EC): The Expert Solution for DBM & Sucking Pests

A broad-spectrum "One Shot" solution by PI Industries that targets resistant pests and improves crop health.

Keefun Insecticide is a premium formulation containing Tolfenpyrad 15% EC. It is specifically engineered to fight tough pests like the Diamondback Moth (DBM) in cabbage and the complex sucking pest group (Thrips, Jassids, Aphids) in vegetables and cash crops. Unlike standard sprays, Keefun works on a unique cellular level to shut down pests that have developed resistance to other chemicals.

Best For: Farmers facing heavy resistance issues in Cabbage, Chilli, Cotton, Okra, and Mango.

Why farmers choose itWhy Choose This Product? Key Benefits
  • ⏱️ Immediate "Stop-Feed" Action: Upon contact, pests are paralyzed and stop eating your crop immediately, preventing further damage even before they die.
  • ?️ Breaks Resistance Barriers: Highly effective against pests that survive traditional sprays (like Organophosphates and Pyrethroids) due to its unique METI chemistry.
  • Multi-Stage Control: Works on all life stages—it kills eggs (ovicidal), nymphs, larvae, and adults, ensuring the population does not bounce back.
  • ?️ Bonus Fungicidal Power: Uniquely controls fungal diseases like Powdery Mildew and Anthracnose alongside insects, saving you the cost of an extra fungicide spray.
  • ? Excellent Crop Health: Prevents "Window Paning" in cabbage and "Leaf Curling" in chilli, resulting in higher quality, export-ready produce.

Product scienceHow It Works: Mode of Action

Keefun operates on the insect's bio-energy system using Mitochondrial Electron Transport Inhibition (METI).

  1. Penetration: The lipophilic formula quickly penetrates the insect's waxy outer layer or is ingested during feeding.
  2. Energy Blockage: It binds to Complex I in the mitochondria, blocking the production of ATP (the cell's energy fuel).
  3. System Shutdown: Without energy, the insect becomes paralyzed, stops feeding immediately, and dies from energy starvation.

This mechanism is completely different from nerve-poison insecticides, which is why it kills pests that other chemicals cannot.

How to applyDosage & Application Guide

The Golden Rule: Always follow the "Dose per Acre" for accurate results. Keefun requires high water volume for best coverage.

How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
CropDose (ml / Acre)Water (L / Acre)Dose (ml / Litre)PHI (Days)
Cabbage400 ml200 Litres2.0 ml5 Days
Chilli / Mango400 ml200 Litres2.0 ml7 Days
Okra / Cotton400 ml200 Litres2.0 ml3 - 26 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 first sign of pest infestation (Egg or early Larval stage). For best results, spray during cooler hours (early morning or late evening).
  • Mixing: Use clean water. Do NOT mix with highly alkaline products like Bordeaux mixture or Lime Sulfur, as this reduces efficacy.
  • Coverage: Keefun is a contact insecticide. Use a Hollow Cone nozzle and ensure thorough coverage of both the upper and lower leaf surfaces.
  • Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying when honeybees are actively foraging.
