Why use chemicals at all in your robots? Why not mechanical means like punching them into the soil?

Microwaves might also be an interesting approach. We should chat.

The main reason to avoid any sort of mechanical kill is time. Even if you could deploy and retract a puncher in 100 ms, you'd travel 10 inches during that time. The slowest operation in row crops is about 6mph. Same principle applies to microwaves & lasers. All require time over the target. Chemicals are nice b/c they do their work after your machine leaves and its easy to get a solenoid that opens and closes in 5ms.

There are other issues w/ exploding seed head making the problem worse and w/ making reliable complex moving parts in the horrible ag environment.

Happy to chat. Contact in profile.
