Equation Pro Fungicide: Famoxadone + Cymoxanil Guide

Equation Pro is an advanced dual-action fungicide developed by Corteva Agriscience, formulated with Famoxadone 16.6% + Cymoxanil 22.1% SC. Combining an oxazolidinedione contact protectant with an aliphatic nitrogen penetrant (FRAC Group 11 and FRAC Group 27), Equation Pro delivers potent multi-stage defense against destructive Oomycete plant pathogens. Indian potato, tomato, and grape growers rely on Equation Pro for preventative, curative, and anti-sporulant control of late blight and downy mildew.

Dual active synergy and multi-action biochemical mechanism

Equation Pro combines two distinct chemical molecules that attack oomycete pathogens at multiple lifecycle stages.

  • Famoxadone (FRAC Group 11): Contact protectant binding tightly to leaf cuticles, inhibiting mitochondrial respiration and stopping spore germination.
  • Cymoxanil (FRAC Group 27): Rapidly penetrates leaf tissue, stopping internal mycelial development with strong post-infection curative action.
  • Anti-sporulant efficacy: Halts viable sporangia production, preventing secondary disease cycles within the field.
  • Suspension concentrate (SC) formulation: Ensures fine droplet misting, uniform leaf adhesion, and excellent rainfastness.

Target crops and major Oomycete plant diseases

Equation Pro is officially registered under CIBRC guidelines for managing aggressive water-mould blights.

  • Potato: Prevention and curative suppression of late blight (Phytophthora infestans) during canopy development and tuber formation.
  • Tomato: Protection of leaves, stems, and green fruit clusters from devastating tomato late blight.
  • Grapes: Control of downy mildew (Plasmopara viticola) during vegetative shoot flushes and pre-bloom stages.
  • Quick rainfastness: Cymoxanil penetrates foliage within 1 to 2 hours, securing disease protection against sudden monsoon rain.

Application timing, spray volume, and resistance management

Apply Equation Pro preventatively when weather forecasts predict cool, humid conditions, or immediately upon detecting initial water-soaked lesions. Use calibrated knapsack or power sprayers with hollow cone nozzles for thorough canopy coverage. To delay fungicide resistance, limit applications to two consecutive sprays; rotate with multi-site protectants like Mancozeb.
