Abstract-Plant diseases have a detrimental effect on the health of food production in
agriculture. As a consequence, it significantly decreases the quality, quantity, and
productivity of the yield. Thus, for sustainable agriculture, automated detection and
diagnosis of plant diseases at an early stage of growth are highly desired. While several
computer vision-based applications have been suggested for this process, they still suffer
from long-lasting training/testing time with large datasets. Besides, due to the hardware
limitation and computational complexity, such model development is crucial in handheld
devices. This research presents a new transfer learning-based optimized EfficientDet
deep learning framework as a practical solution for automated plant disease detection.
The proposed model performance is evaluated in terms of mean average precision (mAP).
It achieves an overall mAP of 74.10% with a substantially fewer number of parameters and
floating point operations per second than other state-of-the-art approaches.
& MODERN TECHNOLOGIES HAVE allowed human
civilization to provide enough food for more
than 7 billion people worldwide. However, food
security remains a fundamental issue affecting
several factors, such as climate change,1 plant
diseases,2 biotic stress, and others. Plant

diseases threaten global food security and create
severe repercussions for small farmers,
whose livelihoods depend on healthy crops.
More than 80% of agricultural production is produced
by smallholder farmers, and at the same
time, more than 50% of loss is seen due to pests
and diseases. Consistent efforts are made to prevent
crop loss by consulting many domain
experts to support agriculture extension organizations
and other institutions. It is a costly,
labor-intensive, and time-consuming process.
