Product scienceHow It Works: Mode of Action

Solaro works by disrupting the energy production of the weed. It is a systemic herbicide that is primarily absorbed through the roots.

  1. Absorption: The herbicide is applied to the soil. As weeds germinate, their roots absorb the chemical along with water.
  2. Translocation: It travels up the plant (via xylem) to the leaves and chloroplasts.
  3. Inhibition: It blocks Photosystem II, preventing the weed from converting sunlight into energy. This leads to starvation, yellowing (chlorosis), and death of the weed.

Note: Maize and Sugarcane have natural enzymes that break down Atrazine rapidly, which is why the crop survives while the weed dies.

How to applyDosage & Application Guide

The Golden Rule: Always follow the "Dose per Acre" for accurate results. Ensure soil has sufficient moisture at the time of application.

How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
CropDose (g / Acre)Water (L / Acre)Dose (g / Litre)PHI (Days)
Maize (Light Soil)400 g200 L2 g/L--
Maize (Heavy Soil)800 g200 L4 g/L--
Sugarcane400 - 1600 g200 L2 - 8 g/L--

*PHI = Pre-Harvest Interval: Use as per statutory guidelines. *Dose varies by soil type (Heavy clay soils need higher doses than sandy soils).

Useful detailsHow to Apply: Best Practices
  • Timing: Pre-Emergence: Apply immediately after sowing (0-3 days). Early Post-Emergence: Can be applied up to the 2-leaf stage of weeds.
  • Mixing: This is a Wettable Powder (WP). Pre-mix the required quantity in a bucket with a little water to form a thin paste, then pour into the spray tank and fill with water. Keep agitated.
  • Coverage: Use a flat fan or flood jet nozzle. Ensure the soil is moist at the time of application for the chemical to activate.
  • Safety: Always wear PPE (gloves, mask, goggles) as the powder can cause dust inhalation. Wash hands thoroughly after use.
