25% Paclobutrazol aqueous suspension concentrates
Paclobutrazol is a plant growth regulator, which has the effects of delaying plant growth, inhibiting stem elongation, shortening internodes, promoting plant tillering, increasing plant stress resistance and improving yield. Paclobutrazol is suitable for rice, wheat, peanuts, fruit trees, tobacco, rape, soybean, flowers, lawn and other crops, with remarkable effect.
