Charcoal Rot
These soil borne diseases are most often observed when temperatures are high and plants are stressed. This disease frequently occur in the desert. Death of crown leaves combined with grey stem lesions are symptoms associated with charcoal rot. Structures diagnostic for M. cannonballus can be seen as small, black, round structures protruding from the dead root tissue of affected plants.
Control Measures
There are no control measures currently recommended for charcoal rot. Cultural practices such as rotation, deep plowing and maintenance of soil moisture have not been effective. There has been little or no effective disease control by using solarisation or fumigation. Charcoal rot may be found in the same fields at the same time as Monosporascus vine decline, and control measures recommended for this vine decline may also be beneficial in reducing charcoal rot.
