Footrot of sweetpotato is a fairly minor disease, but in a commercial field can result in significant economic losses. While disaster potential for sweetpotatoes with footrot is relatively inconsequential, it is still advisable to learn how to controlfootrot in sweetpotatoes. Ipomoea batatas (sweetpotato) is up to now the only economically important host. The disease also attacks some other Convolvulaceous hosts.Lopes, C.A. and Silva J.B.C. 1993.Management measures to controlfootrot of sweetpotato caused by Plenodomus destruens. Sweetpotatofoot-rot is considered one of the most destructive diseases of this crop. The pathogen, Plenodomus destruens , causes stem necrosis and root rot, leading to the plants death. In order to explore the field resistance identification method of sweetpotato ( Ipomoea batatas ) footrot and to screen resistant germplasm, a total of 81 germplasms with resistance or other traits were identified after 1-3 years experiment... Sweetpotatofootrot disease, which was first confirmed in Japan in 2018, has now spread to 21 prefectures. As a result, the yield of sweetpotatoes decreased and the wholesale price increased. Biological control of plant pathogens by Bacillus species is widely disseminated in agrosystems, but specific biological control agents against the footrot disease-causing fungus are not yet available. Our previous studies showed that two Bacillus strains isolated from sweetpotato... Shima T, Ochiai M, Kobayashi Y, Ishii T, Kobayashi T, Kamada E, Saitou K, Sekiguchi H, Yoshida S (2024) Effective control measures for sweetpotatofootrot disease in severely affected areas based on network analysis (in Japanese, English summary). Sweetpotatofootrot disease caused by Diaporthe destruens (formerly Plenodomus destruens) severely affects the yield and quality of sweetpotatoes. 2.1. Plant Materials. Four sweetpotato cultivars were used throughout this experiment: ‘Tamaakane’, ‘Konaishin’, ‘Kokei No. 14’, and ‘Beniharuka’. These cultivars were selected based on known information on footrot ecology and control measures [ 22 ]. The use of real-time PCR assays may provide a new approach for managing footrot disease of sweetpotato. Currently, there are no chemicals that can be effectively used to control the disease (Kobayashi, 2019).
