ABSTRACT

The present study was aimed to investigate the insecticidal and fungicidal activities of Prunus persica (L.) Batsch stem bark. The methanolic extract of stem bark of Prunus persica (L.) Batsch was tested for its insecticidal activity against mustard aphid Lipaphis erysimi under in vitro condition. The insect mortality percentage was found to be increase with the corresponding increase in dosage indicating a direct relationship between the percentage mortality and dosage %. The highest mortality percent (97%) of Lipaphis erysimi was observed with 2.0 mg/L concentration of methanolic extract of Prunus persica in 24 hrs, whereas the lowest mortality percent (6%) was found with 0.5 mg/L concentration in 24 hrs. The statistical probit range indicates good activity against Lipaphis erysimi. The extract was also tested for its fungicidal activity against Fusarium oxysporum. The extract showed 30.33 % and 74.77 % growth inhabitation with 2 % and 20 % concentration, respectively. Thus, the present study revealed that the plant extract have a remarkable insecticidal and fungicidal activities.

Keywords: Prunus persica, Lipaphis erysimi, Fusarium oxysporum, insecticidal and fungicidal activities.
