That's cool, yeah, precise targeting should remove the need for highly toxic herbicide.

That seems opposite to me. Precise targeting would allow the use of highly toxic herbicides in minute quantities.

The reason herbicides have to be highly toxic is that they are sprayed indiscriminately, so only small quantities actually get on the target. Farmers don't prefer highly toxic things. They would prefer to use less toxic things, applied directly in large quantities to the target and not elsewhere.

Do the least harm possible!
