Peanut pre-emergence and crown rot investigations

1953

Morwood, R.B.

The results of investigations covering a number of years are reported. Crown rot is caused by Aspergillus niger. Pre-emergence rot is due to Rhizopus arrhizus, Aspergillus niger and probably other organisms. Seed treatment, particularly with organic mercurial fungicides and the organic fungicide thiram, improves field emergence, sometimes to a remarkable extent. The previous cropping history of the soil has a marked influence on losses from pre-emergence crown rots.
