Abstract:

Damage and loss of crops and plants caused by pathogens are global problems that have major effects on the food supply of many countries. Environmentally friendly viricide approaches are gaining in popularity to combat these problems. This study proposes the use of environmentally friendly hydrogen peroxide (HP) as a pesticide entrapped in a poly(vinyl alcohol) (PVA)/polyvinylpyrrolidone (PVP) hydrogel for controlled release in agricultural applications. The hydrogel was prepared as a matrix of PVA and PVP containing HP. Freeze–thaw cycles of the PVA/PVP/HP hydrogel improve the mechanical properties and thereby decrease the HP release rate. The hydrogel chemical composition, morphology, and HP release rate through direct and indirect (gas phase) contact were investigated. Viricide capabilities were tested, indicating a high efficiency against ToBRFV on tobacco and tomato plants. Additionally, low to zero phytotoxicity was found for HP release. These results demonstrate the future potential of hydrogen peroxide-loaded hydrogels as effective viricide agrogels.
