Structure: 
Prohexadione calcium is a kind of plant growth retardant hormone, which can be absorbed by plant seeds, roots and leaves to inhibit the synthesis of gibberellic acid, and has dwarfing and lodging resistance effects on crops.
1. Quick effect, within 3 days.
2. Inhibit the growth of internodes, improve lodging-resistance.
3. Protect gibberellin’s active already existing and prevent presenility of crops.
4. Efficient,safety,non-toxicity and residue free.
| The Dosage of Prohexadione Calcium Used on Different Crops | |||
| Crops | Dosage(mg/L) | Method of use | Effects |
| Rice | 2-3 | foliar spray 5-10days before jointing stage | Reduce internodes height, prompt lodging- resistant and the development of grains or fruits, increase crop yield |
| Sorghum | 3-6 | 27-30days after jointing stage, foliar spray | Controling the ultimate height of sorghum |
| Peanut | 2 | Between full-blooming stage and pod setting stage , foliage spray | Reduce peanut’s plant height, increase fruit number and fat content, increase crop yield markedly |
| Cotton | 1.5-3 | Once between early florescence and full-bloom stage | Inhibit the vegetative growth of leaves and branches, reduce plant height obviously, increase crop yield and promote quality |
| Apple | 2.25-4.5 | Spraying 3 times in fall flowering stage, fruit bearing stage and physiological fruit drop stage | Inhibit the vegetative growth of leaves and branches, increase crop yield, it can preventive Fire blight (Erwinia amylovora) and other diseases caused by bacterium or fungoid |
| Grape | 3-6 | Foliar spray after flower faded | Inhibit the vegetative growth of grape, improve the pigment and phenolic content of grape juice, improve the quality of grape |
| Chrysanthemum, kale, Dianthus caryophyllus and other ornamental plants | 1.5-3 | Foliar spray | Inducing dwarf, keeping leaves Green, slowing down senescence, no bad effect to leaves and flowers |
| Agrostis, cynodon, smooth meadow grass, perennial ryegrass, zoysia grass and so on | 3-20
Different lawn with different dosage |
3-5days after mowing, foliar spray | Reduce the height of new plant by 50-90%, reduce the number of mowing |
