We do not see any reason that you could not use a fungicide along with Sevin Concentrate they are both used as directed on the product labels.

No, Sevin Concentrate is an insecticide that can be sprayed on ornamental trees. It does not have any herbicidal properties to it and would not harm trees if applied according to the instructions on the product label.
Sevin Concentrate will kill the adult termites that are sprayed with the product. It will not replace a termite soil treatment around the perimeter of the structure. There are products that you can use to treat in the tree directly. Just keep in mind that termites are there because the tree is already dead or dying, so be sure to take down dead trees before they cause other damage. You could use Alpine Ant and Termite Foam to spot treat exactly where the galleries are in the tree. This product has a foaming agent to help coat the inside of any voids. Alternatively, you could use Dominion 2L as a spray, again treating inside the galleries directly. We would recommend using a termiticide like Taurus SC against the foundation in a trench or drilled holes (where there is concrete). You can find more information on doing a complete treatment for termites in our Termite Control Guide.
Sevin Concentrate can take time to kill insects, depending on the age and health, how long they spend on the treated area and how soon after application they contact it. It can take a few hours up to 24 or more for insects to die. You will just need to monitor the treated plants for any more signs of insects.
Sevin Concentrate is labeled to control millipedes when used as directed on the product label.
You will mix 1.5 ounces of Sevin Concentrate per gallon of water for grasshoppers.
