Pythium diseases
Pythium
sp.
Pringsh.
Host: burley tobacco (Nicotiana tabacum (burley type)
L.)
Descriptor: Symptoms
Description: 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.
