- formulation: Prohexadione calcium 95% TC
- Specification: FAO quality standard
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.
Plant growth regulator
Calcium 3-oxido-5-oxo-4-propionylcyclohexanecarboxylate; VIVIFUL; 3,5-dioxo-4-(1-oxopropyl)cyclohexanecarboxylicacidion(1-)calciumcalciums
Form: yellow powder.
Melt point: above360°C
Solubility: (20°C mg/l):Water 174, methanol 1.1, acetone 0.038
Stability: stable under light, heat and in aqueous solution, but not stable in alkaline
Toxicity: low toxicity, easily can be disintegrated to CO2 and H2O, no residual, and
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.
Increase fertility, reduce lodging, promote growth of bud and root, keep stem and leaves
green, control flower time, improve setting percentage, promote fruit mature. Enhance
hardiness to lighten herbicides injury.
