Keith from Cashion, Okla writes,

Is Mixing Pin Dee possible with Roundup to kill existing weeds that have already came up??


The product label for Pin Dee 3.3 EC Herbicide does give instructions for tanking mixing with glyphosate products.  Do not apply tank mixtures containing glyphosate over the top of ornamental plants. Before tank mixing, a simple jar test is recommended to insure compatibility of herbicides. Always read the companion product label. Follow all use precautions and restrictions that apply to each product used. Always follow the most restrictive label.
