Abstract
Fusarium wilt diseases of vegetable crops are the major challenges for vegetable production. To explore alternative control measure of Fusarium wilt, antifungal activities of nickel nanoparticles were investigated for controlling two forma specials of Fusarium oxysporum, F. oxysporum f. sp. lactucae and F. oxysporum f. sp. lycopersici, on lettuce and tomato under in vitro and greenhouse conditions. Under in vitro condition, nickel nanoparticles at the concentration of 100 ppm significantly inhibited the mycelial proliferation and sporulation activities of fungal pathogens. The inhibition of mycelial growth of F. oxysporum f. sp. lactucae and F. oxysporum f. sp. lycopersici was 60.23 and 59.77%, respectively. While under greenhouse condition, nickel nanoparticles at the concentration of 50 ppm caused the highest reduction in disease severity and the reduction was 58.4% and 57.0% on lettuce and tomato, respectively. However, when the plants were inoculated with fungal pathogens before application of nickel nanoparticles, the concentration of 50 ppm was found more effective than 100 ppm of NiNPs in relation to plant health. The application of nickel nanoparticles at 100 ppm significantly retarded the plant growth as compared to application of nickel nanoparticles at 50 ppm in all combinations of treatments. So, we conclude that the application of NiNPs as antifungal agents against Fusarium will be better with concentration of 50 ppm. This study suggests that nickel nanoparticles could be used to control Fusarium wilt. However, further field studies are needed to verify their disease control efficiency and effects on soil physicochemical properties and other beneficial soil microorganisms.
