There are typically no issues mixing different kinds of sprays together, such as an insecticide and fertilizer or fertilizer with herbicide. We always recommend doing a small jar test for compatability when mixing any products together for the first time, unless the product labels expressly address the tank mix you are using.
There are two things I would caution you against with these mixtures. One is if you are using herbicides for your turfgrass and wanting to use an insecticide for mosquito control at the same time. For mosquito control, you want to use a product like Talstar P on ornamental shrubs, tree branches, etc.; however, you should not spray post-emergent herbicides like Drive, Tenacity, or Trimec on these areas since those herbicides would damage your ornamental plants.
We would also be careful about mixing more than 2 herbicides at one time since this could cause extra stress on your turfgrass.
Please let us know if you have any other questions.
Talstar P is labeled for beetles and is safe for use on lilies, as well as other ornamentals. The residual is 30 days outdoors. It is recommended that you spray when pollinators are not active, either in the early morning or late evening. The mixing rate is 1 fl oz per gallon of water.
Most insecticides and herbicides are able to be tank mixed together, just make sure you follow each product label instructions for "tank mixing" instructions.
Talstar P is able to be tank mixed according the label but since we do not carry T-Zone Weed Killer, we cannot confirm the tank mix compatability.
We couldn't state whether it would be effective or safe to use an essential oil in with a tank mix of Talstar P or any other insecticide as this has not been tested for efficacy or compatibility. It is recommended not doing so unless both products labels state tank mixing with another chemical can be done.
