Pythium spp. |
Stem rot occurs on tobacco transplants shortly after they are set in the field. Stem rot may begin in the plant bed and be moved to the field on infected transplants, or it may begin after plants are set in the field. The development of stem rot is sporadic, being favored by wet weather and injured plants. Under favorable conditions, Pythium attacks the stems of newly set plants causing brown, watery lesions to develop near the soil line. As the fungus disease develops, stem tissue collapse and disintegrate, causing death of the plant. Stem rot usually appears as a watery soft rot; a cottony fungus mass may be present. Stem rot may be confused with sore shin or black shank, thus requiring microscopic examination for confirmation. |

Pythium diseases |
Pythium spp. |
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. |
