- Аннотация: Zeroxxe® is a new fungicide and bactericide product with a broad spectrum of activity against phytopathogenic fungi, oomycetes and bacteria. In Russia, Zeroxxe® is in the final stage of the four-year registration process as the world's first fungicide and bactericide containing nanosilver as an active component. An active substance of Zeroxxe® is silver nanoparticles (silver NPs, 3000 ppm) stabilized with environmentally safe biodegradable amphoteric surfactant. In vitro studies of Zeroxxe® revealed its high efficacy against a wide range of fungal pathogens of potato: Rhizoctonia solani (black scurf), Phytophthora infestans (late blight), Colletotrichum coccodes (black dot), Helminthosporium solani (silver scurf), Alternaria solani and A. alternata (early blight), Fusarium solani (dry rot), Sclerotinia sclerotiorum (sclerotinia rot). To assess the bactericidal effect of Zeroxxe® six types of pathogenic bacteria were tested: Pectobacterium carotovorum (soft rot of potatoes and vegetables), Dickeya dianthicola (black leg and soft rot of potato), Agrobacterium tumefaciens (bacterial cancer of fruit, ornamental plants and grapes), Xanthomonas vesicatoria (bacterial black spot of tomato), Clavibacter michiganensis (bacterial cancer of tomato and potato), Xanthomonas campestris (vascular bacteriosis of cabbage and rape). 30 minutes incubation of bacteria in the solution of Zeroxxe® (100 ppm of silver NPs) completely inhibits growth of all bacteria. In the case of 10 ppm solution 45-85% of all colonies were inhibited. The results prove the potential of Zeroxxe® as a fungicide and bactericide for pre-plant treatment of various seeds and tubers, treatment of vegetating plants, as well as for the treatment of tuber and root crops before storage.
