Starfix is a plant growth regulator containing Alpha Naphthyl Acetic Acid (NAA) 4.5% SL, used to improve fruit set, reduce premature flower/fruit drop, and regulate plant growth in horticultural and field crops.
Starfix is a synthetic auxin-based plant growth regulator formulated with NAA 4.5% SL, widely used in fruit and vegetable production systems. NAA is a well-documented plant hormone that regulates cell division, fruit retention, and vegetative growth balance.
It is primarily used to prevent flower and fruit drop, improve fruit setting, and enhance overall crop productivity. The product is applied as a foliar spray at specific crop stages depending on flowering and fruiting cycles.
Verified agronomic sources confirm that NAA 4.5% SL formulations are standard commercial PGRs used globally for fruit retention and yield improvement in crops such as apple, citrus, mango, and vegetables.
