That's fine once that's been demonstrated to be effective. It has not. Until that time, the only effective control is to have the farmers themselves mix the 2% strychnine solution.
I've read both of the documents involved, which came from the study you did in 2005, or at least presented in 2005. The statements you made about that, again, are simply not backed up by what's in the report.
This product has been taken away from farmers, costing possibly $200 million, or possibly more, per year, and again there simply aren't any good reasons. This is something that's been done without proper consideration and without evidence that would indicate that it should have been done. It was a bad decision, costing farmers a lot of money when they clearly can't afford that.
