GP wasn't talking about crops, but about the selective pressure that would be placed on weeds to better survive laser attacks. I could imagine that weeds would either develop heat resistance or would change appearance to make detection harder.

Changing appearance to avoid detection is as old a agriculture. In fact it's why we have some foods we enjoy now. https://en.m.wikipedia.org/wiki/Vavilovian_mimicry
