The multifunctionalcytochromeP450monooxygenases P450-1 and P450-2 from Fusarium fujikuroi catalyze the formation of GA14 and GA4, respectively, in the gibberellin (GA)-biosynthetic pathway. However, the activity of these enzymes is qualitatively and quantitatively different in mutants lacking the NADPH:cytochromeP450 oxidoreductase (CPR) compared to CPR-containing strains. 3beta-Hydroxylation,
The invention relates to a liquid dispersion comprising (i) at least one growth regulator which has a solubility in vegetable oil of about 0.1 wt% or less; (ii) an organic hydrophobic carrier, preferably a vegetable oil, hydrocarbon oil or paraffin oil, or a derivative thereof; wherein the at least one growth regulator which is insoluble or unstable in water, is present in the liquid dispersion in an amount exceeding 0.1 wt%; and wherein more than 90% of the particles of said growth regulator has a particle size of between 1-7 µm; wherein the dispersion further comprises (iii) an emulsifier which stabilizes the dispersion in the organic carrier, and which causes the concentrate to be water miscible and self-emulsifying when diluted in water in a suitable dilution, such as for example a 1:50 dilution or higher dilution; wherein the dispersion is essentially water free.
The invention relates to a liquid, substantially anhydrous concentrate comprising at least 0.1 wt% of metal ions, 0.3 wt% carboxylic acid compound which is soluble in glycol, and at least 40 wt% of a glycol compound. The metal ion preferably is chosen from zinc, manganese, selenium, iron, copper, molybdenum, and magnesium and mixtures of these. The concentrate may contain metal ions in an amount of between 0.3-5 wt%, preferably 0.4-3 wt%.
