Description

Dry bean and field pea root rots have resulted in substantial yield losses in North Dakota. Root rot symptoms range from small lesions to complete root destruction. Traditional management practices such as seed treatment fungicides and crop rotation have proven insufficient under high disease pressure. The objective of this research was to determine the efficacy of in-furrow fungicide applications for management of dry bean and field pea root rot under field and greenhouse conditions. Fungicides were applied in-furrow at planting on dry beans and field peas. In most trials, the inoculated/non-treated control displayed significantly higher levels of root rot than the non-inoculated/non-treated control. In-furrow fungicides generally reduced root rot severity, sometimes significantly over the seed treatment; however, the level of control varied among hosts and pathogens. The results of these studies indicate that the use of in-furrow fungicides, along with cultural practices, may improve the overall management of root rot.
