Overview
The long term goal of this project was to determine the biological basis for different management programs between banana (Musa AAA) and plantain (Musa AAB) for Black Sigatoka disease.
Objectives
1. To determine variability between isolate of Mycosphaerella fijiens obtained from banana and plantain 2. To determine the relative susceptibility of banana and plantain to M. fijiensis 3. To relate environmental factors to disease development in both crops.
Outcomes
The research found that banana is more susceptible to Black Sigatoka (BS) than plantain; therefore, IPM approaches should be different for each crop. This is especially true in relation to the timing for fungicide applications. These studies provide the first report of differences between isolates of M. fijiensisin Ecuador. This information should, in the near future, be related to disease control measures. Data from field studies and accurate monitoring of environmental variables will provide inputs to more effectively time fungicide application to control BS.
