Abstract
Pests and diseases pose a key challenge to passion fruit farmers across Uganda and East Africa in general. They lead to
loss of investment as yields reduce and losses increases. As the majority of the farmers including passion fruit farmers, in the
country are smallholder farmers from low-income households, they do not have sufficient information and means to combat
these challenges. While, passion fruits have the potential to improve the well-being of these farmers given their short maturity
period and high market value [1], without the required knowledge about the health of their crops, farmers can not intervene
promptly to turn the situation around.
For this work, we partnered with the Uganda National Crop Research Institute (NaCRRI) to develop a dataset of expertly
labeled passion fruit plant leaves and fruits, both diseased and healthy. We made use of their extension service to collect images
from five districts in Uganda to create the dataset. Using the dataset, we are applying state-of-the-art techniques in machine
learning, specifically deep learning at scale for object detection and classification for accurate plant health status prediction.
While deep learning techniques have been applied to various disease diagnosis contexts with varying degrees of success([2],
[3], [4], [5], [6]), there has not been any significant effort, to the best of our knowledge, to create a dataset or apply machine
learning techniques to passion fruits despite their obvious financial benefits.
With this work, we hope to fill this gap by generating and making publically available an image dataset focusing on passion
fruit plant diseases and pest damage and training the first generation of machine learning-based models for passion fruit plant
disease identification using this dataset. The initial focus is on the locally prevalent woodiness (viral) and brown spot (fungal)
diseases.
