Like I said earlier, I have plenty of experience treating it in normal situations like you just mentioned.
This application is under different circumstances.


From the Alabama Coop Extension Sys:

Cogongrass benefits from fire. The rhizomes (underground stems) resprout very quickly and aggressively following a fire (figure 2) and often come in more densely than before the fire. Flowering is promoted by winter fires (figures 3 and 4), and the seed, which needs mineral soil to germinate, can establish more easily on ground cleared by fire.
