Focused research

Roam Technology is a producer of silver-stabilised hydrogen peroxide, a known biocide used to disinfect irrigation water. The effects of different concentrations and different exposure times on a water sample contaminated with ToBRFV, as well as on surfaces contaminated with ToBRFV, were investigated. A qPCR test examined the presence or absence of the entire virus, as well as the presence of active virus particles. This is possible thanks to a recently developed laboratory test, which also provides a more correct picture.

Caroline explains that disinfection of water with 1% Huwa-San TR-50 and a reaction time of 14 hours results in an absence of ToBRFV. “Both the test that looks for active material and the qPCR test could no longer detect ToBRFV. Disinfecting the irrigation system during crop rotation with Huwa-San TR-50 is therefore one of the sought-after pieces of the puzzle in the fight against ToBRFV.”

Stabilised hydrogen peroxide also has applications during cultivation. Tests show that a solution with 200 ppm Huwa-San TR-50 and an application time of 12 hours significantly reduces the presence of ToBRFV. Caroline explains that this is a concentration that is often applied temporarily during cultivation, especially when there is a high microbial load. “This makes it an effective way to reduce further spread.”
