  • How long does spinosad last?

    Created by Guenter Meiburg on January 5, 2019 at 2:50 pm

    My Monterey Garden Spray containing Spinosad worked so well last year on my Golden Delicious apple tree I had NO codling moth worms in any apple! My question is, can I still use the remainder of the 1 pint container for an effective mix in 2019? Or should I buy a new one?

    Hi Guenter –

    If properly stored (i.e., protected from excessive light, heat and cold), Spinosad will last up to 5 years. Therefore, your Monterey Garden Spray will still be effective against pests through the 2019 growing season.

    Happy gardening!
