Biochemical Composition & Mechanism
Fantac Plus is formulated with protein hydrolysates delivering biologically active L-amino acids alongside essential vitamins. These low-molecular weight amino acids are readily absorbed through plant cuticles and stomata.
By supplying ready-to-use amino acid building blocks, the formulation conserves plant energy during critical physiological stages such as flower bud differentiation, fruit setting, and periods of thermal or moisture stress.
- Active Ingredients: Hydrolyzed protein amino acids and plant vitamins
- Formulation Type: Liquid concentrate designed for foliar application
- Physiological Role: Promotes cell division, chlorophyll synthesis, and reproductive set
- Regulatory Class: Governed under the Fertilizer Control Order (FCO) 2021 biostimulant specifications
Recommended Target Crops & Application Stages
Fantac Plus is used across a diverse spectrum of crops, including cotton, chillies, tomatoes, pulses, oilseeds, and orchard crops (pomegranate, mango, and citrus).
Spray timing is critical for maximum efficacy: the first application is typically made during early vegetative branching, followed by a second spray at peak floral initiation to minimize flower shed.
- Stage 1: Active vegetative growth to enhance canopy development and root branching
- Stage 2: Pre-flowering stage to stimulate flower bud formation and uniform bloom
- Stage 3: Early fruit/pod development to prevent fruit drop and enhance sizing
- Spray Quality: Ensure fine mist coverage over both upper and lower leaf surfaces
Tank-Mix Compatibility & Safe Handling
The formulation is compatible with most standard neutral insecticides and fungicides, allowing convenient tank mixing to reduce farm labor costs. However, physical compatibility jar testing is always advisable before large-scale tank mixes.
Avoid mixing with highly alkaline sprays such as Bordeaux mixture or lime-sulphur, as alkaline hydrolysis degrades organic amino acid chains.
- Compatibility: Tank-mixable with most non-alkaline insecticides and fungicides
- Water Quality: Use clean, neutral-pH farm water to prevent active ingredient precipitation
- Storage: Store in a cool, shaded environment away from direct sun and extreme heat

Common questions
What is the primary benefit of applying Fantac Plus?
Its primary benefit is stimulating floral initiation, significantly reducing flower and fruit drop, and improving overall plant vigor under adverse climatic conditions.
Can Fantac Plus be combined with routine insecticidal sprays?
Yes, it is compatible with most standard neutral insecticides and fungicides, though jar-testing a small sample before tank mixing is always good practice.
Does Fantac Plus replace primary NPK fertilizers?
No, it is a biostimulant that enhances nutrient uptake and physiological metabolism; it complements but does not replace basal and top-dressed NPK fertilization.
