It appears the two viruses, even though different species, have been engineered with the same spike protein targeting the ACE receptor.
It seems highly unusual that two different types of viruses would target human ACE receptors, unless they were engineered to do so.
Question is, since the vaccines didn’t work (my mother had vaccines and boosters and Covid hit her hard) can hydroxychloroquine or ivermectin be used?
But yes, you are right, an enemy would want farms and infrastructure. In nuclear war there are warheads specifically targeting farms of the Midwest and Mississippi delta to spread radioactive soil all into the atmosphere.
Not a good choice if you want the land.

No, not something that simple, a lab developing a biological weapon will develop an “antidote” in conjunction with the weapon usually before the invention of the weapon. As most biological weapons research involves gene sequencing and other techniques the absolute necessity of developing an “antidote” goes hand in hand with the development of the weapon and today will proceed the development of the weapon.
This is something that the development of nuclear weapons
taught the researchers. Self-interest prevails you don’t want to kill off your guys before you have a chance to kill the enemy...
