About Planofix
Planofix (Alpha Naphthyl Acetic Acid 4.5% SL) by Bayer Crop Science India is an aqueous plant growth regulator solution used to induce flowering, prevent the shedding of buds, flowers, and unripe fruits, and enlarge fruit size. It effectively improves fruit retention and uniformity in crops such as pineapple, tomato, chilli, mango, cotton, and grapes, helping the plant hold on to more of its flowers and fruit through to harvest. By inhibiting the natural production of ethylene, the hormone responsible for the abscission layer that causes flower, bud, and fruit drops. Planofix increases both the quantity and quality of yield. It is applied as a foliar spray, timed to each crop's flowering or fruit-development stage, in recommended crops.
Planofix Technical Name
Alpha-Naphthyl Acetic Acid (NAA)
Mode of Action: Planofix's NAA, inhibits the natural production of ethylene gas in plants. Ethylene is the plant hormone responsible for initiating the abscission layer that causes flowers, buds, and unripe fruits to shed. By suppressing ethylene production, Planofix disrupts the formation of this layer and prevents the natural shedding process, while also enlarging fruit size and improving fruit quality.
Time of Application: Flowering Stage / Fruit Development Stage / Pre-Harvest Stage (crop-dependent)
Key Features & Benefits
-
Induces Flowering & Uniform Growth: Supports earlier, more even flowering.
-
Prevents Shedding of Buds, Flowers & Unripe Fruits: Reduces natural fruit and flower drop.
-
Enlarges Fruit Size: Improves fruit size in pineapple and grapes.
-
Increases Yield & Improves Fruit Quality: Supports better overall harvest quality.
-
Reduces Pre-Harvest Berry Drop: Minimizes berry drop in grapes ahead of harvest.
-
Controls Malformation in Mango: Helps manage malformation when applied before fruit bud differentiation.

Planofix Expert Advice
" For best results, time Planofix application precisely to the crop's flowering, fruit-development, or pre-harvest stage as specified on the label, and spray to the point of run-off for thorough coverage. In multi-spray crops like chilli, mango, and grapes, keep to the recommended interval between sprays for consistent flower and fruit retention."–BigHaat Agronomy Expert
