I have tested the TriColi-Stop by taking a crop swap on 3 pigeons and then recording the results. All 3 had mild canker (3/10 severity) and have never been treated before.
We then gave them TriColi-Stop and tested them 1 hour and 20 minutes later. All 3 were clear and I saw a few dead canker/tricomonas floating around.
We are very impressed with the product!
It is really amazing how well it worked and I did not believe it was possible to clear canker so fast!!
