A disease affecting banana plants has spread to five provinces of Burundi, raising concern among agricultural officials, who fear the disease could hit the country's food security. According to Adelin Girukwishaka, a plant protection officer in the Ministry of Agriculture, the disease, "Banana Xanthomonas Wilt" - commonly known as banana blight - was first detected in November 2010 in Cankuzo province, near the border with Tanzania. "In January 2011, the disease was reported in the eastern province of Ruyigi and Makamba in the south; the disease has also been identified at Cibitoke and Bujumbura Rural provinces," Girukwishaka said. Ernest Manirambona, deputy coordinator of the Food and Agriculture Organization's emergency coordination unit, told IRIN: "The disease is now confirmed; it spread to five provinces within six months." Leonard Ndayishimiye, a farmer in the northwestern province of Cibitoke, said the disease had infected most of his plantation; he is worried his monthly income will drop as a result.
