Has a hydrogen peroxide base, is 90% biodegradable, non-irritating and non-corrosive at 1% dilution.

Mode of Action

DuPontTM VirkonŽ S does not elicit a specific toxicological effect on the target organism, instead it achieves deactivation and/or destruction of the target organism through general oxidative disruption of key structures and compounds vital to normal activity (e.g. proteins and lipids).

There is no evidence to suggest that bacterial disease causing organisms develop resistance towards VirkonŽ S as opposed to other disinfectant types.

Pigeon Use - as told by Frank McLaughlin (with permission)

Virkon S is a disinfectant sold by Dupont. Not only is it the most amazing disinfectant you will ever use in the lofts for sanitation but it is simply magic when used in the pigeons drinking water.

Virkon S should be the first line of defense for any young bird sickness. If the pigeons start to go off whether it is a young bird sickness or possible other affliction add 1/2 to 3/4 teaspoon to the gallon of water for five days. Usually within two days all symptoms have disappeared. By day five the birds look spectacular. Virkon S must be added to the water after the containers are filled and then stirred. It will form up if added first and then water is added. Like any disinfectant be careful to keep Virkon S out of your eyes and try not to inhale the powder. Better to be safe.

As a general health aid give the pigeons three days of Virkon S every six to eight weeks. Virkon S seems to have a positive effect against all bacteria, virus, fungi and canker. We use it during breeding, molting and racing will no ill effects.

Chicken breeders have been giving Virkon S to chicks for years. The chicks live better, grow better and losses are lessened.

We add Virkon S to the bath water in the same above dose.
Virkon S is an unbelievable disinfectant to be sprayed in the lofts and all general disinfection and sanitation needs.

After treating with Virkon S please give several days of friendly gut bacteria and vitamins.

Virkon S can be given at the dose of one teaspoon to the gallon if your pigeons are experiencing Circo-virus. The product will not cure infected pigeons but it will stop the spread of the virus. In the case of Circo Virus you can remove sick pigeons and keep the remaining pigeons on Virkon S until the pigeons are no longer becoming sick. This may take a week to ten days. Like I said if the pigeons is already infected with Circo, Virkon S may or may not help. The benefit lies in stopping the virus from spreading.

I get asked all the time "can you use Virkon S during breeding season"? On June 18th I put all my breeders on Virkon S at the dose of 3/4 teaspoon to the gallon. I have babies at all stages of development and every breeder and youngster looks a super as ever. Droppings are firm and normal.

You will notice that if a pigeon has a minor respiratory problem the Virkon S will turn the wattle slightly yellow. At the end of the five day treatment the wattle will be white and dry.

I have been reading how Koi Fish Breeders and keepers used Virkon S in the ponds and tanks to cure and prevent many difference virus and bacteria. They also claim it works at a very low dose and does not effect the biological filter (friendly bacteria). If fish can thrive in the presence of Virkon S, this is a very good sign.
