Katyayani MaxHarvest | Paclobutrazol 40% SC | Plant Growth Regulator

Katyayani MaxHarvest Paclobutrazol 40% SC costs ₹3,350 for 1 litre on katyayanikrishidirect.com, about ₹100 per 30 ml. Competing branded 40% SC products sell for around ₹6,300 per litre, so pack size and brand make a large difference.

Paclobutrazol blocks gibberellin biosynthesis by inhibiting the enzyme that converts ent-kaurene. With less gibberellin the plant stops putting energy into shoot elongation and diverts it into flowering, fruit set and root growth instead.

Paclobutrazol 40% SC controls excessive vegetative growth and improves flowering and pod set. In India it is used in pigeon pea and soybean at 30 ml per acre, in potato, onion and garlic, and as a soil drench in mango.

There is no single best. Match the formulation to the crop: 23% SC is the CIB-registered grade for mango, dosed per tree by age, while 40% SC is used in field crops at 30 ml per acre. Compare cost per acre, not price per bottle.

The method depends on the crop. In pigeon pea, soybean, potato, onion and garlic, spray 30 ml per acre in 200 litres of water at flower or bulb initiation. In mango, apply only as a soil drench at the trunk base — never spray it on the leaves.

Paclobutrazol shortens internodes and controls excess vegetative growth, which reduces lodging, improves light penetration, and shifts the plant into flowering and pod or fruit set. In mango it helps regulate biennial bearing and encourages more uniform flowering.

Paclobutrazol shortens internodes and produces compact, darker green plants with thicker stems and a stronger root system. Vegetative growth slows while flowering and fruiting increase. The effect lasts several weeks in annual crops and a full season in trees.

Apply paclobutrazol to mango between July and October, after harvest and about three to four months before expected flowering, as a soil drench at the trunk base. Dose is set by tree age: roughly 15 ml per tree at 7–15 years, rising with age.

Indian brands include Katyayani MaxHarvest and Katyayani Fast, Vestar from Bharat Certis, Zermia from Mankind and Paclo-40. Choose by formulation strength for your crop, check the CIB&RC registration covers that crop, and compare cost per acre.

Paclobutrazol 23% SC, the grade registered for mango, is widely sold in India in 100 ml to 1 litre packs. Prices vary by brand and pack size, so compare on cost per tree at the recommended dose rather than on bottle price.

Yes. Paclobutrazol is a triazole plant growth regulator, not a fertilizer or pesticide. It works by inhibiting gibberellin biosynthesis, which restrains shoot growth and redirects the plant's energy into flowering, fruiting and root development.

Paclobutrazol is the ISO common name. Its chemical name is (2RS,3RS)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pentan-3-ol, and its CAS number is 76738-62-0. It belongs to the triazole class of growth regulators.
