Product scienceHow It Works: Mode of Action

Master Stroke uses a dual-action strategy to ensure a "Complete Kill" of weeds without harming your cotton crop.

  1. Pyrithiobac Sodium (Broadleaf Killer): Absorbed by roots and leaves, it stops the production of essential amino acids in broadleaf weeds, causing them to turn yellow and die.
  2. Quizalofop-Ethyl (Grass Killer): Specifically targets grassy weeds by inhibiting lipid (fat) synthesis, destroying the growing points and preventing regrowth.
  3. Synergistic Effect: The combination ensures that weeds which naturally survive single-molecule sprays are effectively controlled in one go.

The result is a clean field where your cotton crop gets 100% of the sunlight, water, and nutrients.

How to applyDosage & Application Guide

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

*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 when weeds are at the 2 to 4 leaf stage (approx 20-25 days after sowing). Weeds larger than 5 leaves are harder to kill.
  • Mixing: Use at least 150-200 liters of water per acre. Good coverage is essential for success.
  • Method: Use a Knapsack sprayer with a Flat Fan or Flood Jet nozzle. Do not use low-volume power sprayers.
  • Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid drift onto nearby Maize, Sorghum, or Pulse crops.
