Abstract
\r\n Soilborne diseases are a critical problem for peanut producers in Effingham County and must be addressed with additional on-farm research to establish “best management” practices. The producers’ current best line of defense to combat these problems involves selection of more-resistant varieties, judicious use of fungicides, and soil fumigation with metam sodium to reduce severity of Cylindrocladium black rot (CBR). Unfortunately, foliar fungicides and more-resistant varieties are insufficient to manage CBR in Effingham County and our growers are unlikely to use fumigation to manage the disease. In this study, the effectiveness of prothioconazole (Proline) applied in-furrow at planting was evaluated for the management of peanut diseases. Provost (prothioconazole + tebuconazole) and Artisan (flutolanil + propiconazole)/chlorothalonil were evaluated with Proline (prothioconazole) to assess the best program for overall disease protection. Unlike white mold demonstrations, this project is unique in that no research has been done on the management of CBR in the Southeast. In-furrow use of prothioconazole is a new practice for our peanut growers, and there is an important need for data on this product in the southeast from large-plot, on-farm trials. From the research in Effingham County, the effectiveness of prothioconazole as a part of a disease management program to improve plant stand and reduce other disease such as TSWV, CBR, and white mold has been addressed. These results will play an important role in recommendations for future use of prothioconazole in the Southeast.
