MaxPar® BSO

High-Purity Spray Oil

Overview


MaxPar BSO 75 is a high purity spray oil used as a carrier for fungicides and insecticides that protect plant life against disease and pests. It is biodegradable and safe to the end-user and has an ultra-high unsulfonated residue level that keeps toxicity to plants very low.

MaxPar BSO 75 can be used as a carrier for fungicides to control both Yellow and Black Sigatoka disease. By coating the leaf with a thin film of oil, the oil will give the selected fungicide optimal time to slow the fungi growth. Pests will also avoid protected plant life if customers add insecticides to the formula.

MaxPar BSO 75 is produced from highly-refined paraffinic oil and is a technical-grade white oil. In general, the refinement level of spray oil is measured by its unsulfonated residue (UR). The higher the UR level, the less toxic it is, and the more saturated the oil is rated. When spray oil has a lower UR level, it can be much more damaging to plant life. MaxPar BSO 75 has a UR level of 92% as a minimum, and evidence shows that any spray oil that falls under a 90% UR level drastically increases toxicity.

The vacuum distillation midpoint measures the time it takes for a spray oil to evaporate. A higher midpoint will allow the oil to evaporate slower and provide added time for fungicides and insecticides to protect the plant life for a more extended period. A distillation midpoint of 400 degrees Fahrenheit is considered the lowest level before a spray oil is deemed ineffective. The average midpoint for MaxPar BSO 75 is 418 degrees Fahrenheit.
