Multiplex Magnum Mn (Manganese EDTA 12%) | Premium Chelated Micronutrient

Cure "Hidden Hunger" and Boost Crop Immunity with High-Stability Manganese.

Multiplex Magnum Mn is a specialized micronutrient fertilizer containing 12% Manganese in a chelated EDTA form. Unlike standard sulfate salts that get locked up in the soil, this advanced chelated formula ensures your crops actually absorb the nutrients they need. It effectively treats Manganese deficiency, cures yellowing between veins, and corrects specific disorders like "Gray Speck" in cereals and "Pahala Blight" in sugarcane.

Best For: Correcting chlorosis (yellowing), improving photosynthesis, and strengthening plants against fungal diseases.

Why farmers choose itWhy Choose This Product? Key Benefits
  • ⏱️ Fast-Acting Correction: The EDTA chelation acts like a protective claw, preventing the Manganese from getting fixed in the soil. This ensures 100% availability and rapid absorption by plant leaves.
  • ?️ Disease Resistance Builder: Helps plants produce Lignin, which toughens cell walls. This acts as a physical shield, making it harder for fungal pathogens like Brown Spot and viral infections to penetrate the crop.
  • High Stability Formula: Remains effective in a wide range of soil pH levels and tank mixes. It is far superior to Manganese Sulfate, which often precipitates and becomes useless in alkaline soils.
  • ?️ Photosynthesis Booster: Manganese is the "battery" for the water-splitting reaction in photosynthesis. Magnum Mn restores chlorophyll function, turning yellow leaves green and maximizing energy production.
  • ? Complete Crop Safety: Designed as a gentle, water-soluble powder that won't scorch leaves when used as directed, making it safe for sensitive stages like flowering and fruit setting.

Product scienceHow It Works: Mode of Action

Manganese is a "transition metal" that acts as a spark plug for plant metabolism. Magnum Mn delivers this nutrient in a protected form that enters the plant system immediately.

  1. Activates Photosynthesis: It powers the "Oxygen Evolving Complex" (OEC) in leaves, which is responsible for splitting water molecules and releasing oxygen. Without this, plants cannot create energy from sunlight.
  2. Enzyme Regulation: It activates critical enzymes in the Krebs cycle (respiration) and helps process Nitrogen. This prevents the buildup of toxic ammonia in plant tissues and aids in protein synthesis.
  3. Structural Defense: It catalyzes the production of lignin and phenolic compounds. These materials harden the plant skin (cuticle), creating a tough physical barrier that stops fungi and insects from penetrating.

Result: A greener, stronger plant that photosynthesizes efficiently and fights off diseases naturally.

How to applyDosage & Application Guide

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

How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
CropDose (g / Acre)Water (L / Acre)Dose (g / Litre)PHI (Days)
Field Crops (Rice, Wheat, Maize)100 g200 L0.5 g-
Vegetables & Horticulture100 g - 200 g200 - 400 L0.5 g-
Plantations (Sugarcane, Fruit Trees)250 g - 500 g500 - 1000 L0.5 g-

*PHI = Pre-Harvest Interval: No specific PHI is mandated for micronutrients, but stop spraying 15 days before harvest.

Useful detailsHow to Apply: Best Practices
  • Timing: Spray during the cool hours of the day (early morning or late evening) to ensure the liquid stays on the leaf longer for maximum absorption.
  • Mixing: Always perform a "Jar Test" first. Add Multiplex Magnum Mn to the tank last. Use a wetting agent (like Multiplex Maxiwet) to help the spray spread evenly on waxy leaves.
  • Coverage: Ensure thorough coverage of the foliage, spraying both the upper and underside of leaves where stomata are located.
  • Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhaling the powder dust.
