A unique, straight prohexadione-calcium formulation allowing flexibility to tailor PGR programmes.
The only straight prohexadione-calcium product available in the UK, specifically developed for cereals.
Can be co-applied in bespoke ratios with other PGRs, enabling applications to be tailored to both crop requirement and conditions of the season
Chemically and Biologically – chlormequat is an excellent mixing partner for Prohex
Chlormequat chloride has a complimentary mode of action which supports prohexadione. Prohexadione-calcium is not active as a PGR – it requires conversion into the active prohexadione acid form. Chlormequat chloride acidifies the spray solution, aiding the conversion of prohexadione-calcium from the inactive calcium salt to the active acid form.
Now approved for use in oats
Enabling greater Plant Growth Regulator choice.
OD is an abbreviation for Oil Dispersion. An OD formulation is a solid active ingredient, with very low oil solubility which is very finely milled and dispersed in oil. The oil can be paraffinic, aromatic solvents, vegetable oil or methylated seed oil. Our formulation is based on a bio-renewable vegetable oil.
Other prohexadione-calcium formulations are available as a suspension concentrates (SC)
An SC formulation of prohexadione-calcium is not optimal due to its relatively high water solubility (0.78g/L)
Small prohexadione solids can dissolve in water and redeposit on larger particles, leading to expanding crystal growth. A process known as Ostwald ripening.
This chemical instability can lead to stored product becoming faulty overtime and needing to be replaced.
In an OD, there is no water and the formulation is stable for long periods of time unlike other prohexadione-calcium formulations
