| [Aims] This study aims to screen effective fungicides for the prevention and control of pear rust, and to provide scientific basis for the prevention and control of pear rust.[Method] The field efficacy test was carried out with six fungicides.[Result] The six fungicides all had effects on the control of pear rust. azoxystrobin 250 g/L SC 125 ga.i./hm2 has the best effect on pear rust, reaching 64.56%; pyraclostrobin 250 g/L EC 180 ga.i./hm2 has the fastest effect, reaching 59.27%. [Conclusion] azoxystrobin 250g/L SC 125ga.i./hm2 and pyraclostrobin 250 g/L EC 180 ga.i./hm2 are effective in preventing and curing pear rust, and both can cure the lesion . |
