Abstract:
Diverse pesticidal activities of anthothecol derived from K haya anthotheca ( M eliaceae) and three limonoids (gedunin, limonin and obacunone) were determined using six phytopathogenic fungi and four insect pests. Anthothecol showed fungicidal activity to P uccinia recondita with control rates of 90, 76 and 53% at concentrations 0.5, 0.25 and 0.1 mg/mL, respectively, while the other limonoids exhibited little inhibitory effect on the fungal survival. The currently used fungicide mancozeb possessed potent fungicidal activity on P . recondite , with 92.3% controlling effect at a concentration of 0.005 mg/mL. Anthothecol exhibited larvicidal activity to P lutella xylostella with 80, 50 and 30% mortality at concentrations of 1.0, 0.5 and 0.25 mg/mL, respectively. Anthothecol showed selective pesticidal activity on P . recondita and P . xylostella . Structural re‐examination of anthothecol was conducted and is reported.
