We used to slurry atrazine 80 wp all the time way back when. Sevin wp was the same. This was 45+ years ago. I think it would be fine to do that with first rate.
My bigger concern would be the general agitation in your sprayer. I seem to recall that first rate was a fairly low rate use product. As in, we didn't really have to put a large volume in the sprayer per load. If your sprayer can not dissolve and suspend something like that, it may be time to upgrade the agitation in the system even if it meant a new pump etc. You can have too much agitation but I would rather err to the high side than to the low side.
