Customer Reviews for OHP Marathon 1% Granular Insecticide

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.

I have used Marathon 1% granular for over 10 years and it will amaze you how effective it is regardless the problem. (aphids, mealy bugs). It will not kill ants though, but that's not a big problem usually because other ground insecticides will do.
