Hello Dave. Enjoyed visiting with you in San Marcos as well. Besides the legally improper labeling issue, small-packaged "Garden-Labeled" rotenone isn't what I'd call an economical option for such covert purposes. One website that I found lists a 12 oz. container of Rotenone 5% Powder at a $15.93/lb. equivalency. Fish-control treatments generally require about 10 lbs. of 5% rotenone powder per acre-foot. Based on this info, it would cost approx $637 to effectively treat a small 1-acre pond with a 4' avg depth. Not exactly what I'd call cheap - especially considering the very real risk of being shot, labeling-laws and the amount of time and manual labor required; not to mention that you can legally buy a lot of fish at the market with that kind of money. However, I'm pretty sure that spoons are the typical eating utensil in prison. For one's own legal purposes, it would be well worthwhile to obtain the appropriate license. Otherwise, hire the job to a professional. It is the private-market's circumvention of pesticide label-laws that will quickly bring an end to private pesticide availability - ie. chlordane, Dursban, etc. KD
