It has been discovered that AAL-toxin, a known host-specific phytotoxin produced by Alternaria alternate f. Sp. lycopersici, has a broad range as a pre-emergent or post-emergent bioherbicide. A method using AAL-toxin has been developed for controlling certain weeds, including duckweeds, jimsonweed, black nightshade, prickly sida, redroot pigweed and northern jointvetch. This phytotoxin can be used pure, as a cell-free filtrate, a crude filtrate, or a crude suspension of the culture.
