  • 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.

  • NOVONEST4 and applications thereof
    Patent number: 11503833
    Abstract: Strain of Bacillus thuringiensis novonest4 and applications thereof. The Bacillus thuringiensis is the Bacillus thuringiensis novonest4, with an Accession No. CCTCC NO: M2018443. The strain is firstly reported to have both the effect of preventing and controlling lepidoptera pests after foilar application and the effects of degrading carbendazim, promoting crop growth and increasing crop yield after soil application, and has wide application prospects in agricultural production.
