More and more growers are discovering how they can easily render algae, fungi, and viruses harmless in their water systems, namely by placing a USAF ultrasonic transmitter in places where water is stored, such as basins, silos, and drain pits. At the request of growers, there is now also a 115-volt version. It will be supplied from the end of March 2023. With its USAF cavitating ultrasonic transmitters, Ultramins is gaining momentum.
"With our ultrasonic transmitters, algae and biofilm disappear from any basin in up to 30 days. In silos, we usually render all pathogens harmless with 6-10 hours of treatment, i.c.w. an oxidizing agent such as hydrogen peroxide."
Inquiries for a 115-volt version came mainly from the United States. "After extensive testing by USAF, we now also have this version, which is high quality, available." Ultramins also gives its regular 7-year usage guarantee on the 115-volt transmitters. "The operation of this new variant is similar to that of the well-known 230-volt version. The control of all pathogens in the (drain) water is therefore identical."
ToBRFV and Cucumber green mottle mosaic virus (CGMMV)
The transmitters are also used by growers in the fight against Tomato brown rugose fruit virus (ToBRFV). Ultramins also had trials conducted for this purpose to prove the transmitters' effectiveness against the dreaded virus. Ron Peters of Proeftuin Ron Peters, now FutureGrowing, conducted the tests.
In the test in 2021, the cultivation water was deliberately extremely polluted with ToBRFV, in values that are never achieved in practice at growers. Unlike in many virus studies, the choice was made to administer the virus to the plants via water, moreover, in a very high dose. Ron said at the time: "Because of this, we now know that the transmitters work well, precisely because such high doses of ToBRFV do not occur in practice." Not once was a Ct value below 32 found. Kees Luijkx, the manufacturer of the USAF transmitters, added: "The ultrasonic shock wave breaks the virus in one blow. After that, a small amount of hydrogen peroxide ensures that what is broken stays broken."
Ultramins transmitter application in Canada
Cucumber green mottle mosaic virus (GCMMV), like ToBRFV, is also a Tobamovirus and can be rendered harmless in drain water by using these ultrasonic transmitters, Robert stresses.
