Abstract: By determining the lethality rate to Meloidogyne incognita and Caenorhabditis elegans, it was found that the methylmalonic acid has a better nematicidal effect on the Caenorhabditis elegans, with the LC50 being 13.11 and 1.20 for the Meloidogyne incognita and the Caenorhabditis elegans, respectively. After compounding the methylmalonic acid with betaine, the LC50 was 2.85 and 0.27 for the Meloidogyne incognita and the Caenorhabditis elegans, respectively. Meanwhile, the methylmalonic acid also has an inhibiting effect on Pseudomonas solanacearum and Erwinia carotovora. The preparation of the methylmalonic acid provides a new choice for preparing novel biocontrol agents against the root-knot nematodes.
