  • POLYSUBSTITUTED NITROGEN-CONTAINING HETEROCYCLIC DERIVATIVES, PREPARATION METHOD AND USE THEREOF
    Publication number: 20240215578
    Abstract: The present invention provides a polysubstituted nitrogen-containing heterocyclic derivative, a preparation method, and use thereof. In the present invention, the novel structure of the natural nitrogen-containing heterocyclic molecule is designed to obtain the polysubstituted nitrogen-containing heterocyclic derivative. The polysubstituted nitrogen-containing heterocyclic derivatives have obvious bactericidal activity, and some compounds have significant bactericidal activity against diseases such as E. carotovora, E. coli, and R. solanacearum, which can be widely applied in the comprehensive prevention and control of agricultural and forestry bacterial diseases. The bactericide obtained by mixing the polysubstituted nitrogen-containing heterocyclic derivative of the present invention with various adjuvants also have good bactericidal effects on E. coli, E. carotovora, R. solanacearum, etc.

  • Application of methylmalonic acid in the preparation of nematode insecticides
    Patent number: 11723360
    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.
