Aspergillis Crown Rot in Peanut

Posted by romeethredge on June 5, 2015

We are seeing more aspergillis crown rot in peanuts this week. It’s a disease that kills seedlings and when you dig them up you can see a lot of black sooty material on them.  Not much we can do about it but supply water to the peanuts. An at plant application of Abound fungicide in furrow helps this situation.

Here are some comments from Dr. Bob Kemerait, UGA Plant pathologist, concerning this. “Aspergillus crown rot and Diplodia collar rot have been associated with dead and dying seedlings and young plants.  Such is very common in when soils are HOT and DRY as the tender tissue at the soil line is damaged/injured and the fungal pathogens can infect.  Aspergillus crown rot is also very common on saved seed of reduced quality and when a seed treatment is not used. “
