Biological <strong>limitations</strong><br />

It is desirable for a bioherbicide to act relatively quickly <strong>and</strong> have sufficient<br />

efficacy to control weeds. Unfortunately, many of the weed pathogens<br />

discovered may provide only partial control of only one weed species, even under<br />

ideal conditions (CHARUDATTAN, 2005).<br />

Host specificity is related to the basic biology of the pathogen <strong>and</strong> to host<br />

variability (GABRIEL, 1991; LEONARD, 1982). Biological constra<strong>in</strong>ts <strong>in</strong>clud<strong>in</strong>g<br />

host variability <strong>and</strong> resistance, as well (AULD, 2003).<br />
