Pythium diseases (Pythium spp. ) on burley tobacco (Nicotiana tabacum (burley type)) - 1440004

Pythium diseases
Pythium sp. Pringsh.

Host: burley tobacco (Nicotiana tabacum (burley type) L.)
Descriptor: Symptoms
Description: Damping-off affects tobacco at any stage of growth in the plant bed. The disease first appears as irregular areas of wilted, yellowed, stunted, or dead plants. These symptoms are the result of girdling of the lower stem of the tobacco plants by either Rhizoctonia or Pythium fungi species.Pythium usually affects the young tobacco plant near the soil line. A soft, brown, watery rot girdles the stem, causing the plants to fall over. Plants affected after stems harden may not die but turn yellow due to injury to the stem and root system. Pythium sometimes attacks transplants shortly after they are set in the field, causing a stem rot.
