Production of coffee is constrained by diseases such Coffee Leaf Rust caused by the fungus Hemileia vastatrix. Chemical control is widely used but it is expensive and not environmentally friendly. Hence this experiment was conducted in the laboratory at Coffee Research Institute, Chipinge in November 2015, with the objective of examining the efficacy of four botanical extracts viz Lemon grass (Cymbopogon citratus), Aloe vera (Aloe barbadensis), Moringa (Moringa oleifera) and Tobacco (Nicotiana tabacum) extracts in three different concentrations (100, 50 and 25% leaf extracts) as compared with Copper oxychloride as a standard fungicide and distilled water as a negative control. The experiment was laid in a Completely Randomized Design (CRD) design with a 4 x 3 factorial structure and was replicated four times. The first factor was the above mentioned four botanicals and the second was the respective concentrations (25%, 50% and Original Research Article
