HollyFrontier Horticultural Oils

Over Sixty Years of Producing Effective, Low Toxicity Horticultural Oils

HollyFrontier’s horticultural oils offer a unique combination of pesticidal effectiveness and low toxicity. Tightly refined to meet the most stringent manufacturing and use requirements, these oils provide an economical alternative or supplement to many synthetic organic pesticides in Integrated Pest Management Systems.

Research into the advantages and disadvantages of the use of petroleum oil to kill plant pests has led to the eventual development of specifications for unsulfonated residue (UR) and distillation. These requirements are specific to the crop and the climate in which the crops are grown.

HollyFrontier manufactures two lines of spray oils which meet or exceed these specifications: Sunspray horticultural spray oils, registered as pesticides with the U.S. Environmental Protection Agency (EPA) under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA); and HollyFrontier Ag Oils, carriers for chemical herbicides. This represents the most complete line of “superior” horticultural oils available in the U.S. today.
