Abstract
Plant pathogens are able to affect weedy plants, in part because of the phytotoxins produced by them. Phytotoxins of weedy pathogens are produced in culture media by most of the phytopathogenic fungi of weeds that we have studied. In many cases, the phytotoxins belong to a family of related compounds produced by the pathogen. These phytotoxins belong to a wide array of chemical substances including sesquiterpenoids, sesterterpenoids, diketopiperadines, peptides, spirocyclic lactams, isocoumarins and polyketides. Biological activity is usually observed in the range of 10-3 to 10-6M concentration. The concept of using these molecules and related compounds as herbicides should be explored.
