Function Characteristics:
1.Inhibit the growth of internodes, improve lodging-resistance;
2.Protect gibberellin’s active already existing and prevent presenility of crops;
3.Efficient,safety,non-toxicity and residue free;


Prohexadione calcium TC can't dissolve in water and most organic solvent, it can be made to Water Powder(WP), Suspension Concentrate(SC), Water Dispersible Granule(WDG) and troche and so on. 10% WP, 25% SC, 15% WDG and 5% effervescent tablet(ET) are common in market. Prohexadione calcium works through leaf treatment, so it is usually used foliagespray. The dosage is different with different crops.

The Usage and Dosage of Prohexadione calcium Used on Different Crops

Crops Dosage Method of Use Effect
Rice 2-3 ppm foliagespray 5-10days beforejointing stage Reduce plant height obviously, shorteninternodes height
Sorghum 3-6 ppm 27-30days after jointing stage, foliagespray Controling the ultimate height
Peanut 2 ppm Between full-bloomingstage and pod setting stage , foliage spray Reduce peanut’splant height, prompt the number of under contacts, increase crop yield
Cotton  1.5-2 ppm Once between early florescence and full-bloomstage Inhibitthevegetativegrowth ofleavesandbranches, reduce plant height obviously, increase crop yield and promote quality.
Apple 2.25-4.5 ppm Spraying 3 times in fall flowering stage, fruit bearing stage and physiologicalfruit dropstage Inhibit the vegetative growth of leaves and branches, improve the quality of fruits
Grape 3-6 ppm Foliagespray after flower faded Inhibitthevegetativegrowth of grape, improve the pigment and phenolic content of grape juice, improve the quality of grape
Grass 3-20 ppm 3-5days after mowing, foliagespray Reduce the height of new plant by 50-90%, reduce the number of mowing.


Mechanism of Action:
It can stop synthesis of GA1 through control activity of GA19 and GA20 to control vegetative growth, and promote reproductive growth, improve activity of GA4 to increase yield and improve quality, improve the disease-resistance ability.
