Introduction

In the early phases of the investigation of measures for control of southern sclerotium rot of sugar beets, caused by Sclerotium Rolfsii Sacc., among other lines of attack much attention was given the possibility of destroying the fungus in the soil. It was thought at that time that the fungus might be eradicated by timely application of fungicides. Now that the wide distribution of the disease and the extent of infested tracts in the Sacramento Valley have been determined, workers have realized that such an attack must have limited value.

The sclerotia of this organism are, however, discrete bodies, uniform and convenient in size, furnishing admirable material for the study of the effectiveness of fungicides. It is thought that the following work may show the relative value of several such chemicals and may aid investigators working with less easily handled organisms.
