The base oil used to formulate JMS Stylet-Oil, Organic JMS Stylet-Oil and JMS Stylet-Oil for Grass Seed Use is defined in the industry as a Technical Grade White Mineral Oil (or white oil). The decision to provide growers with a technical grade white oil for disease and insect control was made more than two decades ago by JMS Flower Farms, Inc. Providing growers with a highly refined, superior technical grade white oil has a number of advantages over non-white horticultural oils. The purity (or Unsulfonated Residue) of the base oil used in Stylet-Oil is 99.1%; the purity of non-white horticultural oils is typically 92%. This difference in purity can have significant consequences: There is more active ingredient (ai) in white oils than in typical non-white horticultural oils;
• White oils do not contain aromatic hydrocarbons, thus, these compounds are not freely evaporating into the atmosphere from spray applications. Typical 92% UR horticultural base oils can contain as much as 8% aromatic hydrocarbons — all of which evaporate into the atmosphere as air pollutants;
• Included in these aromatic compounds are suspected Carcinogenic compounds such as benzene, toluene and xylene. After refining, these compounds are not effectively removed from 92% UR oils, but they are removed using the advanced refining processes to manufacture white oil;
• Potential for phytotoxicity (plant injury) is minimized when using white oils due to the removal of impurities, including aromatic compounds.
