To established an integrated management for the cassava witches’ broom disease through chemical (Streptomycin sulfate, sodium hypochlorite solution, and copper-based pesticides), non-chemical (hot watertreatment and biological control agents) approaches, and systemic insecticide-treatment on stem cuttings on mealybug infestation. Specific Objectives: 1. To field validate the efficacy of chemical-based treatments (streptomycin sulfate, sodium hypochlorite and copper-based pesticide) on the development of cassava witches’ broom disease. 2. To field validate the efficacy of non-chemical treatments such as hot water and formulated biological control agents (MagikGRO) and plant extracts (NEB88) on the development of cassava witches’ broom disease. 3. To assess the effect of other field practices such as Dinotefuran 10% WP (Starkle) and other related systemic insecticide application on stem cuttings against mealybug infestation, CWB infection and crop yield. 4. To develop diagnostic protocol for early detection of phytoplasma-causing CWB. Hypothesis to be tested: The non-chemical approaches including the use of HWT, MagikGRO and NEB88 will reduce the incidence and severity of CWB on treated cassava stem cuttings without compromising the viability of the planting materials. The pre-application of Dinotefuran will minimize the infestation of mealybugs in the field.
