A high-power, systemic weed killer designed for total vegetation control in Tea plantations and Non-Crop areas.

Vigor 71 is a modern advancement over traditional liquid glyphosate. Manufactured by Nichino India, it uses a concentrated 71% Soluble Granule (SG) technology. It is specifically engineered to kill stubborn perennial weeds down to the roots, offering superior results even in hard water or rainy conditions compared to older 41% liquid formulations.

Best For: Tea gardens (post-pruning), railway tracks, industrial sites, and clearing wasteland.

Why farmers choose itWhy Choose This Product? Key Benefits
  • ⏱️ Rapid Rainfastness: Absorbs quickly into the plant; safe from rain wash-off within just 2 to 4 hours (compared to 6-8 hours for liquids).
  • ?️ Total Root Kill: Systemic action penetrates deep into underground rhizomes and tubers, ensuring weeds like "Motha" and "Doob" do not regrow.
  • ⏳ Hard Water Stable: Contains built-in Ammonium Sulphate to neutralize hard water, ensuring the medicine works at full strength without extra additives.
  • ?️ High Concentration: The 71% concentration means you carry less weight but get more power. 1 kg of Vigor 71 covers the same area as 2 liters of liquid glyphosate.
  • ? Eco-Smart Packaging: Comes in granules/sachets, significantly reducing plastic waste compared to bulky plastic bottles.

Product scienceHow It Works: Mode of Action

Vigor 71 is a non-selective, systemic herbicide. It does not burn the plant immediately; instead, it slowly shuts down the plant's life support system.

  1. Absorption: The Ammonium salt formulation allows the herbicide to be absorbed rapidly through green leaves and stems.
  2. Translocation (Movement): Once inside, it travels through the plant's vascular system (phloem) down to the roots, rhizomes, and tubers (the "food storage" of the weed).
  3. Inhibition: It blocks the EPSPS enzyme, which is essential for making proteins. Without these proteins, the plant starves and dies completely from the root up.

Note: This is a slow process. Yellowing starts in 5-7 days, and complete death occurs in 14-21 days.

How to applyDosage & Application Guide

The Golden Rule: Always follow the "Dose per Acre" for accurate results. Do not under-dose, or weeds may recover.

How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
CropDose (g / Acre)Water (L / Acre)Dose (g / Litre)PHI (Days)
Tea1200 g (1.2 kg)200 Litres6 gUse after pruning
Non-Crop Areas1200 g (1.2 kg)200 Litres6 g-
Tough Perennials1200 - 1400 g200 Litres6 - 7 g-

*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. For Tea, use "Blanket Application" only when bushes are pruned/skeletonized.

Useful detailsHow to Apply: Best Practices
  • Timing: Apply when weeds are actively growing and have 4-8 leaves. Do not apply on weeds that are flowering or dry/stressed.
  • Mixing: Dissolve granules in clean water. Though it has built-in conditioners, adding 1-2% Ammonium Sulphate can boost results in very hard water.
  • Coverage: Use a Knapsack sprayer with a Flat Fan or Flood Jet Nozzle. Do not use Hollow Cone nozzles (mist) to avoid drift onto crops.
  • Safety: Always wear PPE (gloves, mask, goggles). Vigor 71 is a severe eye irritant—protect your eyes. Wash hands thoroughly after use.
