Abstract
- [Objective] The paper was to screen effective fungicides to control Cordana leaf spot caused by Neocordana musae. [Method] The toxicities of six fungicides against mycelial growth of N. musae were measured by the method of mycelium growth inhibition. [Result] The average EC50 values of six fungicides against mycelial growth ranged from 0.102 9 to 504.065 µg/mL. Among them, 22.5% picoxystrobin SC and 12.5% epoxiconazole SC showed strong inhibitors' activity on mycelial growth, with the average EC% values of 0.102 9 and 0.685 1 µg/mL, respectively; followed by 50% thiophanate-methyl SC, with an average EC50 value of 1.993. 80% Azoxystrobin WG showed a relatively low sensitivity against N. musae, with an average EC50 value of 504.046. [Conclusion] The six fungicides tested have great value in preventing and controlling Cordana leaf spot. 22.5% Picoxystrobin SC, 12.5% epoxiconazole SC and 50% thiophanate-methyl SC have better inhibitory activities on mycelial growth of N. musae, and can be further used in field trials.
