I would like to tank mix the following in a 35 gallon sprayer in the appropriate amounts for my 1 acre yard, Talstar, fertilizer, tenacity, DyneAmic, & blue marker in the early spring. And then Talstar, fertilizer, trimec, drive, DyneAmic. and blue marker in the summer and fall. I *think* from reading labels and Q&A here, that these mixes are acceptable and 35 gallons of water is enough to not have anything be too hot. This mix in this tank towed behind my tractor should (I think) cover my entire yard, which is about 38,000 SqFt. There seems to be a few Q&As that say never to mix insecticides with other treatments. But then there are lots that say it's fine.
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.
