Development of Appropriate Strategies to Control Cassava Diseases in Ghana

Chapter
Part of the Plant Pathology in the 21st Century book series (ICPP, volume 3)

Abstract

Yield of cassava in some of the major production districts of Ghana, where it is the most important staple food crop, is significantly impaired by diseases, including African Cassava Mosaic Disease (ACMD) and root rot caused by Polyporus sulphureus. P. sulphureus, a parasitic fungus, is capable of causing complete crop failure in susceptible cultivars. Varieties were tested for resistance to the major diseases of cassava, particularly ACMD and P. sulphureus root rot in disease hot spot areas in the Kpando District of the Volta Region, using farmer participatory approaches. Nine varieties showed resistance to ACMD and Polyporus root rot while the local farmers’ variety succumbed to a severe attack. Two of the eight varieties gave root yields of 22.0 and 23.0 t/ha compared with 11.0 t/ha obtained from the farmers’ local cultivar. Two hundred farmers and agricultural extension agents from four major cassava producing districts were trained in disease identification and control through workshops and field days. Also two farmer field schools were established in the Sabadu and Aveme farming communities of Kpando District, where local farmers were trained in disease identification and control. A disease identification and control guide was developed, produced and disseminated in the form of booklets and DVDs to increase awareness and promote disease control. With improved disease control practices and cultivation of the disease-resistant varieties identified, farmers can increase and even double yields of edible roots and improve their incomes and food security.
