Valagro Products: Biostimulants, Micronutrients & Nutrition

Valagro (a Syngenta Biologicals company) is a global manufacturer of agricultural biostimulants, chelated micronutrients, and water-soluble plant nutrition formulations marketed extensively in India. Formulations such as Megafol (anti-stress and growth activator), Radifarm (root system development promoter), Kendal (natural resistance booster), and Brexil (chelated micronutrients) utilize natural plant extracts and GeaPower technology to enhance crop yield, fruit set, and resilience against heat, drought, and salinity stresses.

Core product portfolio and GeaPower biological technology

Valagro develops biologically derived crop solutions using proprietary extraction and formulation technologies.

  • Megafol: Formulated with amino acids and betaines to accelerate recovery from abiotic stresses (drought, frost, hail, and heat).
  • Radifarm: Specific root-growth promoter containing zinc, betaines, and amino acids to reduce transplant shock in seedlings.
  • Kendal: Natural resistance activator containing oligosaccharides and glutathione that strengthen internal plant defenses.
  • Brexil range: Micronutrient complexes chelated with LSA (lignin sulphonate) for rapid foliar absorption without phytotoxicity.
  • YieldON: Designed to stimulate cell division and nutrient transport during reproductive stages in field crops.

Physiological benefits across crop development phases

Integrating biostimulants alongside standard soil fertilisers addresses physiological bottlenecks during critical growth stages.

  • Transplanting and early establishment: Promotes deep lateral and adventitious root development.
  • Flowering and fruit set: Enhances pollen viability, improves ovule fertilization, and limits physiological blossom drop.
  • Stress recovery: Restarts stalled metabolic pathways within 24 to 48 hours after severe environmental heat or moisture stress.
  • Fruit sizing and colour: Enhances uniform fruit sizing, sugar brix levels, and storage firmness in commercial horticulture.

Application techniques: Fertigation and foliar spraying

Valagro biostimulants and micronutrients can be applied via micro-irrigation systems or foliar knapsack misting. For foliar applications, spray during the early morning or late evening when stomata are open. Products meet rigorous quality specifications governed under the Fertilizer (Control) Order (FCO).

Common questions

What is the primary role of Valagro biostimulants in agriculture?

They optimize plant metabolic efficiency, promote root and shoot growth, and protect crops against abiotic environmental stresses.

How does Megafol help crops recover from drought or heat stress?

Megafol provides ready amino acids, betaines, and vitamins that restart plant protein synthesis and cellular repair after stress.

Can Valagro Brexil chelated micronutrients be sprayed on sensitive fruits?

Yes, Brexil uses organic LSA chelates that provide gentle, highly absorbable micronutrients with minimal risk of foliar leaf scorching.
