Evaluation of The Incidence and Severity of Moler Disease on Shallot in Peatland Area

Abstract Moler disease caused by Fusarium can cause serious damage to shallots and significantly reduce yields. This study aimed to evaluate the incidence and severity of moler disease on shallots in peatland areas. In this study, field survey was conducted to determine the incidence and severity of shallots plantation on peatlands and mineral soil in the Lopak Alai Kasang Village, Kumpeh Ulu District, Muaro Jambi, Jambi. The stury was conducted from June – August 2023. Results of this study showed that moler disease was found in 5 varieties of shallot, namely Bima, SS Sakato, Singkil Gajah, Sumbu Merapi , and Linggogeni. Results of this study showed that disease incidence and disease severity of moler disease in this study was range from 5,06 – 80,64% and 2,86 – 100% depend on variety and location. Although moler disease in shallots has been thoroughly investigated in mineral soils, its frequency and severity in peatland environments remain poorly documented. Thus, this information will be useful to develop the control strategies on moler diseases to maintain the health and productivity of the plants in the future.
