In this study, we aimed to identify acaricidal compounds in Inula japonica against Tetranychus cinnabarinus. Here, I. japonica petroleum-ether extracts were found toxic to T. cinnabarinus with a LC50 value of 1.18 mg/ml. Silica gel column chromatography was used to further separate acaricidal components from I. japonica petroleum-ether extracts. Contact toxicity data showed that 17 out of 38 fractions groups had mite mortality rates above 50%, 9 fraction groups above 60 %, and fractions groups… CONTINUE READING
