Compounds according to the spp, or one of their metabolites containing weed control composition and method for controlling weeds with the use of compounds according to the or one of their metabolites spp.
Certain new strains of Drechslera spp. have been found as pathogens effective for the control of barnyard grass (Echinochloa), a troublesome grass in the cultivation of economic crops such as rice and wheat. Weed control compositions containing living fungal cells of one of such strains or a metabolite of the strain and weed control methods using the microorganism or the metabolite of Drechslera spp. are provided. The present invention has made it possible to control barnyard grass without adversely affecting economic crops. Further, the pathogens useful in the practice of this invention are free of the potential problem of environmental contamination inherent in synthesized organic herbicides and can be used safely.
