Soilbome fungi

The use of G. virens and other soilbome fungi for weed control is discussed. 

These compounds are strongly inhibitory towards Pythium ultinnim Trow and Rhizoctonia solani Kuhn, two soilbome fungi responsible for the majority of crop seed and seedling decay. A closer examination of other phytotoxin-producing soilbome fungi may yield additional mycoherbicide candidates as effective as G. virens. 

Various soilbome fungi have been reported to produce phytotoxins, some of which are listed in Table III. Certain phytotoxic compoimds are known to have pronounced n cotoxic activity (eg. moniliformin). Ve have excluded those fungi which have the potential to colonize edible parts of crops and produce mycotoxic... 

Once released into the rhizosphere, SLs induce seed germination of root parasitic plants and hyphal branching of AM fungi. Since plant roots continuously release SLs into the rhizosphere, all soilbome organisms are exposed to SLs when they are...
