IDENTIFICATION AND BIOLOGICAL CONTROL OF BASAL STEM AND ROOT ROT DISEASE OF SNAPDRAGON

IDENTIFICATION AND BIOLOGICAL CONTROL OF BASAL STEM AND ROOT ROT DISEASE OF SNAPDRAGON

For the first time wilt symptoms have been detected on the Snapdragon (<em>Antirrhinum majus </em>L) plants cultivated in the parks of Mosul University. The isolation of fungi from wilted plants on PDA medium revealed the presence of seven genera including; <em>Alternaria,</em&g...
