![]() Chitosan for plant growth promotion and disease suppression against anthracnose in chilli. Characterization of Alternaria species associated with heart rot of pomegranate fruit. ![]() M., Mincuzzi, A., Ippolito, A., Siciliano, I., Pane, A., Gullino, M. Antifungal efficacy of chitosan nanoparticles against phytopathogenic fungi and inhibition of zearalenone production by Fusarium graminearum. These results indicated CS-NPs loaded salicylic acid and silver can be used as promising solution in cassava leaf spot management.Ībdel-Aliem, H. Furthermore, these solutions caused higher cell death/live rate than the zinc oxide NP but lower than flutriafol fungicide. However, the flutriafol fungicide was the highest inhibition, with 70.02% in soaking, 58.41% in spraying. While spraying T8 and T9 inhibited rot diameter by 44.95 and 42.79%, respectively. alternata H-Vi 7 plugs into these two solutions could inhibit mycelia growth and their potential virulence causing rot lesions in detached leaves by 42.26 and 51.11%. Moreover, the CS-NP loaded salicylic acid 400 ppm (T8) and CS-NP loaded silver 200 ppm (T9) could inhibit conidial germination by 32.51 and 23.25%, respectively. The results showed that the control efficacy of the mean both applying methods was 39.79–43.62% in CS-NP formulations, which similar with flutriafol (39.66%) and significantly higher than other solutions. The objectives of this study were to evaluate the effectiveness of chitosan nanoparticle (CS-NP) formulations on reducing (1) cassava leaf spot by applying methods (pre-inoculation and post-inoculation) at net-house and (2) potential virulence of Alternaria alternata in detached leaves. The nanoparticles (NPs) are an ecologically promising way to manage plant disease. The fungicides play an important role for control plant disease but it showed high potential for residue problem, phytopathogens resistance and environmental pollution. ![]() Leaf spot is important disease on cassava, could cause yield loss up to 30%. Cassava is an economically important food crop in Thailand.
