Physical and chemical properties
Light yellow crystalline powder, melting point﹥360℃,vapor pressure 1.33×10-3 pa(20℃), it is stability in light, heat, water solution and alkaline conditions.
1, Inhibit the growth of internodes, improve lodging-resistance;
2, Protect gibberellins’ activity and prevent presenility of crops;
3, Efficient, safety, non-toxicity and residue free.
Prohexadione calcium cannot dissolve in water and most organic solvent, it have other formula like WP, WDG, troche and so on. Prohexadione calcium works through leaf treatment, so foliage spray is the frequently way to use. The dosage is different with different crops.
Skin-rabbit- No skin irritation
Serious eye damage/eye irritation
Eyes-rabbit-Mild eye irritation
Method of use
foliage spray 5-10days before jointing stage
Reduce plant height obviously, shorten internodes height, prompt lodging- resistant and the development of grains or fruits, increase crop yield
27-30days after jointing stage, foliage spray
Controling the ultimate height of sorghum
Between full-blooming stage and pod setting stage , foliage spray
Reduce peanut’s plant height, prompt the number of under contacts, increase fruit number per plant、kernel rate、fat content, increase crop yield markedly
Once between early florescence and full-bloom stage
Inhibit the vegetative growth of leaves and branches, reduce plant height obviously, ventilation and penetrating light, increase crop yield and promote quality.
Spraying 3 times in fall flowering stage, fruit bearing stage and physiological fruit drop stage.
Inhibit the vegetative growth of leaves and branches, improve the quality of fruits, increase crop yield, while it has a very good preventive actions to Fire blight (Erwinia amylovora) and other diseases caused by bacterium or fungoid.
Foliage 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
Inducing dwarf, keeping leaves Green, slowing down senescence, no bad effect to leaves and flowers
Agrostis, cynodon, smooth meadow grass, perennial ryegrass, Japanese carpet grass, zoysia grass and so on
Different kinds of lawn with different dosage
3-5days after mowing, foliage spray
Reduce the height of new plant by 50-90%, reduce mowing times
