  • The following is a quick overview of the important things to know. 
    It is not a replacement for the MSDS (Material Safety Data Sheet)

    APPLICATION: This food grade oil can be used up to the day of harvest.

    Stylet-Oil’s performance is directly related to the quality of spray coverage. Stylet-Oil can be sprayed using a standard pump sprayer, available at any local home and garden center. It is important to spray the plants to the point of runoff.


    Mix Stylet-Oil in water at the rate of 1 to 2 ounces per gallon of water. Note: 1 fluid ounce equals 2 tablespoons. A rate of 1.5 oz. (3 tablespoons)/gallon of water is recommended for most applications.

    Stylet-Oil needs to contact pest insects to kill them, thus under-leaf application may be necessary if that is the location of the pests at the time of application.

    FOR Powdery Mildew:

    Add 3 Tbsp of Stylet Oil per gallon of water to your pump sprayer. Put in Stylet Oil AFTER your water or last ingredient. Agitate before spraying. Be sure and agitate at least every 10 minutes for the proper dispersal of oil.


    For use as an insecticide: Plants should be sprayed weekly or twice weekly depending on level of pest infestation.

    For use as a fungicide: Spray weekly or once every two weeks depending on level of disease pressure.

    For use in mitigating aphid transmission of plant viruses: Initiate sprays when winged aphoids first appear. Spray weekly or twice weekly depending on level of disease/vector pressure.


    STYLET-OIL is NOT compatible with SULFUR:

    There is a 14 day interval between use of Stylet-Oil and sulfur



    Do not spray Stylet-Oil when freezing temperatures are anticipated within 48 hours of an oil application.

    • Do not apply when temperatures are above 90° F (32° C) or when plants are under heat or moisture stress.

    • Do not apply when temperatures are below 50° F (10° C).

    • If daytime temperatures exceed 90° F, spraying should be done at night or early morning

    The restricted Re-entry interval is 4 hours. There is no pre-harvest interval for Stylet-Oil. Use it up to the day of harvest.
