Abstract
Plant diseases are a constant issue in food production, resulting in worldwide losses of 20–40% on an annual
basis and more than $147 billion in damages. In India, more than 150 million farmers have an annual
contribution of nearly 18% to the country's GDP, and timely diagnosis of diseases is not easily accessible in rural
areas because of the very limited availability of trained plant pathologists, which leads to the loss of yields in
the field ranging between 25% and 50%. Most of the existing CNN-based systems are only concerned with the
detection of diseases, and farmers are not provided with any practical suggestions for treatment or input
procurement. In response, we present a lightweight CNN network called AgriNet, trained on the PlantVillage
dataset of 61,486 labeled leaf images that represent 38 different classes for 14 different crops, and present an
Integrated Agro-Diagnostic and Remediation Framework (IADRF) to address this. Under an identical
experimental setup (same dataset, data split and training protocol), AgriNet is compared with Xception, ResNet-
50 and Inception V3 in terms of accuracy, precision, recall, F1-score, number of parameters and inference
latency. The proposed model not only reaches high accuracy of 98.68% but also yields a macro-averaged F1-
score of 98.47% while using far fewer trainable parameters than the conventional CNN architectures. The
prototype IADRF combines disease predictions with a structured collection of information regarding disease
prevention and management and presents it through a user-friendly web interface on a mobile device. The
reported latency results prove the possibility of calculations on the server side and in low resource areas, but
direct deployment of the smartphone and validation at the field level remains a topic for further research.

1. Introduction
The Indian economy is primarily based on agriculture, employing over 150 million farmers and contributing
about 18% to the national GDP. Nevertheless, plant diseases continue to be among the most enduring challenges
to agricultural output worldwide, with yearly crop losses of 20–40% and estimated economic losses exceeding
147 billion dollars globally.

Staple crops such as wheat, rice, maize, and vegetables are attacked by fungal,
bacterial, and viral pathogens that result in large-scale yield degradation and food insecurity. Early and precise
diagnosis of plant diseases is required for effective crop management. Farmers in developing countries like
India, especially rural farmers, still largely rely on visual checking to detect disease symptoms. This is an
inefficient, time-consuming, and subjective process, particularly since numerous diseases present similar visual
symptoms in their early stages.
[2]
This is further compounded by the unavailability of plant pathologists, which
can cause a delay in diagnosis resulting in as much as 50% loss in the field. In recent years, deep learning, in
particular Convolutional Neural Networks (CNNs), has achieved remarkable results in image classification
[3,4]
and is thus a highly attractive approach to automate plant disease classification. Current CNN-based systems
can accurately identify diseased leaves,
[5–7]
but they are limited in that they merely label the disease but do not
offer any helpful information to the farmer. Although a farmer may learn that an apple tree has black rot, the
farmer also needs information on which drugs to apply, how to prevent the disease, and where to buy the
medicine. To address these limitations, in this paper, we propose an Integrated Agro-Diagnostic and
