Hola,

I am curios when you hire someone to come and apply Ronetone in your tank to kill it off, how do they administer the Ronetone?

Thank you
Steve

anyone...anyone

Now yer scarin' us....givemunt agents unner ever' rock an' data heap thesedays....

Rotenone is a restricted use pesticide which requires a state license to purchase and additionally a federal permit to apply to most waters. The licensee and permitee usually not the same person.

Then, there are different kinds of rotenone intended for different uses.....remembering of course that on the label of most pesticides (not labeled for aquatic use) its says these two things, "It is a violation of Federal Law to use this product in a manner inconsistent with its label." followed by, "Do Not Apply Directly to Water." Neither of which means, "Won't work." But otherwise seem fairly clear....

Most of the time, liquid rotenone labeled for use as a "piscicide" (fish poison) is applied with some sort of subsurface injector from a boat. Sometimes with a surface sprayer as well. The toxicant must be evenly distributed throughout the pond in order to work properly. When it starts working, it will be obvious. Usually this is done by a fisheries biologist, lake management person, or other experienced and government sanctioned entity.

There are some, um...er, uh, "recipes" for using rotenone intended for use as vegetable dust or spray, to kill fish with, as well as a host of "natural" substances and methods for doing so. Depends on a lot of things what might or might not work to poison the fish, but not harm unintended targets. Rotenone applied by a biologist or other trained applicator won't hurt nuthin' but the targeted fish. Even if something or somebody eats the fish killed by the process, it won't hurt them. Rotenone is approved for use as a vegetable dust up to the day of harvest.

Back in the day....potassium cyanide made a cheap and easy fish killer, 'course it sometimes killed the applicator too....or at the least a few birds and a cow or two.

Another goody but cheap was anhydrous amonia from a big tank on a big trailer. A loooong hose was dragged behind the boat under the water, all the ammonia immediatly dissolved at the nozzle end and after awhile all the fish would come up and die.

Sack fulla green walnuts, feed laced with rotenone or other poison, hydrated lime, sulfuric acid, and tons of other stuff from off the shelf or out of the woods can be put out to poison fish.

Most of these methods would not be legal ways to fish in state waters.....some not so in private waters either. But putting some fish killing pollutant in the water to catch the fish is at least as old a way to fish as any other.....

Rotenone


I remember when you could buy that stuff at the coop or hardware store.
