Abstract

Meloidogyne incognita is one of the important plant parasitic nematodes which causes root-knot in okra (Abelmoschus esculentus). The use of bintaro (Cerbera manghas) leaf infusion is expected to be an alternative for controlling root-knot nematodes. Bintaro contains bioactive compounds that can be used as a bionematicide. Bintaro leaves were blended, soaked in rice bran and water solution then incubated by aerated and non-aerated condition for three weeks. The infusions were filtered and stored in room temperature. The concentrations of infusion were used in this study are 25%, 50%, and 75%. The result showed that under in vitro test bintaro leaf infusion caused percent mortality of Meloidogyne incognita from 25% up to 100% in 24 hours after treatment. Application of bintaro leaf infusion has no phytotoxic effect on okra. Treatment with BA (aerated bintaro leaf infusion on rice bran solution) 75% and BN (non aerated bintaro leaf infusion on rice bran solution) 75% were able to increase wet weight and dry weight of okra. This research indicates that infusion of bintaro leaf have potential to be developed as a bionematicide.
