Sevin Concentrate is labeled to treat bark beetles. The label states it should not be applied to trees larger than 10 feet tall; this is possibly because doing so would not apply an adequate amount of product to the trunk to be effective in killing insects that contact it. When treating for bark beetles, it is recommended to spray up to 15 feet high since generally they do not go much higher than that. You can use a product like Permethrin SFR to do so. Unfortunately, once the borers have already infested the tree there are not any viable treatment options as they would be protected from sprays. In cases of infestation, the general recommendation is simply to protect the surrounding trees with preventative sprays with a product labeled for such a use. Infested trees will need to be trimmed and/or completely removed.

The Sevin Concentrate should kill any stalk borer that comes into contact with it, that being said, its not a systemic product so its not one that will get taken up by the plant. Common stalk borer caterpillars can be difficult to manage because caterpillars that tunnel into stalks are very well protected. Cultural control for common stalk borer includes any weed management plan that limits or eliminates grasses near field margins. We do not have an effective control for borers that are inside of the stem. Per the Iowa State Extension research article on stalk borers: Plants can sometimes be saved by slicing open the stem and removing the borers by hand. Wilted plants should be considered as a source of additional borer problems and these should be removed and destroyed. The best suggestion is to keep weeds and tall grasses controlled and mowed around gardens and flowers, especially in the fall. This will help eliminate sites that are attractive to the adult moths and the young borers.
Sevin Concentrate is "white to off white" according to the manufacturer's SDS.
