Last month, SciDevNet reported on a hybrid tomato variety that is encouraging Nepali farmers back into tomato production after the majority of plantations were wiped out by storms and disease 5 years ago. The variety, known as Shrijana, is high-yielding, wilt and disease-resistant and flavoursome. The higher yields have increased farmers’ incomes, thus raising their standard of living. This has allowed more farmers in Nepal to send their children to private schools. However, Nepali scientists will continue to research new varieties as it is possible that Shrijana could become susceptible to bacterial wilt over time.
Bacterial wilt is a common and devastating disease affecting a large number of hosts including potato and tomato. It is caused by the bacterium Ralstonia solanacearum which can cause damage to host plants at all growth stages. There are a variety of control measures that have found to be effective against the disease, of which the use of resistant varieties is just one. To read more about additional control measures, read this month’s Plantwise Factsheet for Farmers which was produced by employees from the Horticultural Research and Training Institute (Horti) in Tengeru, Tanzania. Please note this factsheet is also available in Swahili.
