    5 of 5 stars  Great Product
    By Cindy in Crossville, Tn on 01/23/2016

    I have a small greenhouse business raising perennial flowers. I just learned yesterday that if I mix it in the promix (soil) before planting seeds, I can keep the pests away before they get started. I used to sprinkle it on top of plants and water in and it does a great job at keeping ALL bugs off my perennials. It's easy to use and lasts about 3 months per application. I've been using this product for about 15 years. Good stuff.

QCan I use OHP Marathon 1% Granular in the flower garden?
the use instructions are all about containers - I want to use this in the dahlia patch - can I?


OHP Marathon 1% Granular is only for use on labeled containerized ornamentals, fruit and nut trees, and vegetable plants in greenhouses, nurseries, and interior plantscapes. If you let us know what insects you are needing to control and we would be happy to make a proper product recommendation.

QCan I mix Marathon 1% granular directly into potting soil and, if yes, what proportions should be used?
I'm trying to avoid an annual mealybug infestation -- as well as other pests -- on plants in my apartment. Every year they kill off a substantial number of them. After trying all the usual products -- none of which worked -- someone at the nursery recommended Marathon 1%. I plan to repot about 50 plants.


Yes, OHP Marathon 1% Granular can be used in containerized ornamentals, fruit and nut trees, and vegetable plants†in greenhouses, nurseries, and interior plantscapes. The ratio is 1 1/4 - 2 1/2 level teaspoons per container.
