Martins Permethrin 10% does not advise or mention tank mixing on the product label therefore we would recommend doing a small compatibility test in a glass jar first to see if these two products are compatible. The product label for Roundup QuickPro gives instructions for tank mixing on page 2 in Section 6.1 and advises the same compatibility test be done before mixing in a larger tank quantity.
