I also think it's worth considering Carson's passage in the more general discussion of what a technology is versus how it is used. She explicitly says that she's okay with using chemical pesticide as a tool in general. But she's not down with that tool in "the hands of persons…ignorant of their potentials for harm." In debates on modern crop protection (GMOs, anyone?), it is worth separating tools from their potential uses when throwing around labels such as "good" or "bad." It's also worth considering that pesticides and other technologies aren't curealls, but should be used as a complement to other resources. In pest control speak, this is called integrated pest mangament, a tactic Carson advocated for decades ago and that is in place in many programs today.
