Max Size Certified Organic Fertilizer (5L): The Fruit Expander & Yield Booster

Maximize your harvest weight, size, and sweetness with 60% Fish Protein Power.

YK Laboratories "Max Size" (5L) is a professional-grade organic biostimulant designed for commercial farmers. Packed with 60% Fish Crude Proteins and 35% Fish Amino Acids, it acts as a "muscle builder" for your crops. It specifically targets the fruit-setting stage to rapidly expand cell size (hypertrophy), ensuring your Tomatoes, Melons, and Papayas reach their maximum marketable size without using synthetic hormones.

Best For: Commercial Horticulture (Tomato, Chilli, Capsicum, Fruits) looking for Export Quality produce and higher tonnage.

Why farmers choose itWhy Choose This Product? Key Benefits
  • ? Increases Fruit Size & Weight:
    Contains natural Auxins and Amino Acids that trigger rapid cell expansion, preventing small or deformed fruits.
  • ? Boosts Sweetness & Color:
    Improves the mobilization of sugars to the fruit (Brix level), resulting in shiny, attractive, and sweeter produce.
  • ?️ Prevents Fruit Drop:
    Strengthens the fruit stalk (pedicel), reducing the drop of young fruits during heat stress or wind.
  • ⏳ Export Quality (0 Residue):
    NPOP Certified Organic. You can spray it right up to the harvest day (0-day PHI) with no fear of chemical residue rejection.
  • ? Commercial Economy:
    The 5L pack offers massive savings (approx. 30% cheaper per liter) compared to buying small bottles, lowering your cost per acre.

Product scienceHow It Works: Mode of Action

Max Size utilizes "Marine Bio-Technology" to trick the plant into focusing all its energy on fruit development.

  1. Cell Expansion (Hypertrophy): The natural Auxins and Amino Acids signal the fruit cells to stretch and hold more water. This physically increases the volume of the fruit without making it "puffy" or hollow.
  2. Source-Sink Mobilization: It acts like a traffic controller, directing sugars produced in the leaves (Source) to move rapidly into the fruit (Sink). This increases the weight and solid content of the harvest.
  3. Energy Sparing: Plants usually waste energy converting soil nitrogen into proteins. Max Size provides ready-made amino acids, saving the plant energy which it then uses to grow bigger fruits.

Result: Uniform, heavy, and shiny fruits with extended shelf life.

Why farmers choose itTarget Crops & Benefits
CropKey Results
Tomato & ChilliIncreases fruit caliber (size), reduces flower drop, and ensures uniform ripening.
Melons (Watermelon/Musk)Significantly boosts sugar content (Brix) and internal flesh density.
Papaya & BananaPromotes elongation (length) and prevents fruit deformity ("bumpy" fruits).
Leafy VegetablesIncreases leaf width and chlorophyll content for a lush green appearance.
How to applyDosage & Application Guide

The Golden Rule: Timing is everything. Start applying AFTER the fruit has set (pea size) for maximum expansion.

*PHI = Pre-Harvest Interval: You can harvest immediately after spraying.

Useful detailsHow to Apply: Best Practices
  • Timing: Spray in the late afternoon or evening. The protein content absorbs better in cooler temperatures and won't burn leaves under the hot sun.
  • Don't Spray Flowers: Avoid heavy spraying during peak pollination (flowering) to prevent washing away pollen. Wait until the small fruits appear.
  • Tank Mixing: Compatible with most organic pesticides (like Neem or Beauveria). Do NOT mix with heavy copper fungicides or strong chemical herbicides.
  • Storage: Store the 5L can in a cool, dark place. Fish proteins are sensitive to heat and sunlight.
