DERIVATIVES OF (BAUHINIA PURPUREA) LECTIN AND THEIR USE AS LARVICIDES

Document Type and Number:

WIPO Patent Application WO1994002514

Kind Code:

A3

Abstract:

Compounds which are derived from Bauhinia purpurea lectin by replacement of one or more lysine residues in the molecule with other amino acid residues which either preserve the positive charge at the position of the substitution or provide a neutral residue at the position of the substitution are effective larvicides against insects such as European corn borer.
