Spring Sclerotia Sclerotiorum Prevention and Treatment

Sclerotinia sclerotiorum is a serious fungal disease that significantly affects rapeseed crops, causing substantial yield losses if not properly managed. Effective prevention and control measures are essential to minimize its impact and protect the crop. The disease typically manifests through distinct symptoms on both leaves and stems. On the leaves, initial lesions appear as round or irregular-shaped spots with a gray-brown or brown center, surrounded by a dark green or purplish border and a yellow halo. As the infection progresses, the lesions may rupture and dry out, but under moist conditions, they expand rapidly, leading to complete leaf rot and the formation of white mycelium on the surface. On the stems, the lesions are usually fusiform (spindle-shaped), slightly sunken, with a white center and brown margins. In humid environments, these lesions can develop quickly, and white mycelium often appears on the stem surface. In the later stages of the disease, the inner tissues of the stem become hollowed out, the bark splits longitudinally, and the vascular bundles become visible. The roots become fragile and break easily. A key characteristic of advanced infection is the formation of numerous black, granular sclerotia within the stem, which can persist in the soil for years, making future infections more likely. To manage Sclerotinia sclerotiorum effectively, it's important to apply fungicides at the right time—ideally when the main stem has more than 95% flowering, and the first branch is about 50% in bloom. Due to increasing resistance to carbendazim, alternative fungicides such as sclerotinia net, procymidone, valerian (Diacetylcarbide), and cyproconazole (Cyclozole) are recommended. These agents show good efficacy either as single treatments or in combination. For example, 40% sclerotinia net wettable powder can be applied at 100–150 grams per acre, while 50% procymidone (Siklyl) wettable powder can be used at 35–50 grams per acre. Other options include 25% emulsifiable concentrate at 100 grams per acre, 50% Mildew Ling at 100 grams, or 25% Cyproconazole at 25–30 milliliters per acre. A combination product like 50% Fu Mei pairs + sclerotinia net can also be applied at 80–100 grams per acre. In addition to chemical control, cultural practices play a crucial role. Removing yellowing, old, and infected leaves from the entire plant during the flowering stage and disposing of them outside the field can help reduce the spread of the pathogen. Combining these strategies can significantly improve disease management and ensure healthier rapeseed crops.
