Causal Agent: 
Fungus (Sclerotium rolfsii)
| Characteristic Symptoms: | |
|  | The most common symptom is the brown to black rot or sunken tissues of the stem near the soil line, which often lead to wilting and death of the plant. | 
|  | Under moist conditions, mass of white thread-like mycelia develop on the lesion often girdling the stem base and mustard-size light tan to reddish brown, hard and round sclerotia are embedded in the mycelia. | 
| Crops Affected: | |
|  | Solanaceous (pepper, tomato, eggplant) | 
|  | Cucurbits | 
|  | Legumes | 
|  | Allium | 
| Management and Control: | |
|  | Avoid acidic soil.  | 
|  | Application of ammonium nitrate before planting or as side dress can help reduce incidence. | 
|  | Crop rotation with non-host like corn is effective in reducing inoculum in the soil. | 
|  | Drench with chemical fungicides like difenoconazole (e.g. ScoreⓇ, MontanaⓇ, PursueⓇ, BashⓇ), Pyraclostrobin (e.g. Cabrio 25 ECⓇ), metalaxyl+mancozeb (e.g. Ridomil Gold MZ 68 WGⓇ, Apron XL 350 ESⓇ) or carbendazim ( (Bavistin 50 DFⓇ, Goldazim 500 SSⓇ, Minx 500 SCⓇ, SuperdazimⓇ, Avert 50 WPⓇ, BiostinⓇ). |
