Title:
COMPOSITIONS AND METHODS FOR CONTROLLING PLANT PATHOGENS INCLUDING NEMATODES
Document Type and Number:
WIPO Patent Application WO/2024/030365
Kind Code:
A3
Abstract:
Compositions are provided that include: (i) baicalin, or mangiferin and swertiamarin, or mangiferin and hesperidin; (ii) glutathione; and (iii) chitosan. The compositions can kill root knot nematodes within a few seconds of contact and kill larvae of the insects of Coleoptera within 3-18 minutes. Seed treatment with the compositions in combination with a commercial chemical fungicide resulted in enhanced antifungal activity and improved seedling germination and early root growth. Liquid application of the compositions to soil in a greenhouse pot assay with soybean seedlings can result in fewer nematode eggs relative to an industry standard chemical nematicide and application of the compositions to soil in furrow can enhance corn yield relative to a commercial chemical nematicide.
