PANNAI MARUTHUVAM: A MOBILE APPLICATION FOR AI-BASED LEAF DISEASE DETECTION AND MANAGEMENT IN CROPS

Abstract

The "Pannai Maruthuvam" mobile application is an innovative tool designed to help Tamil Nadu farmers detect, diagnose, and manage leaf diseases in crops. Utilizing advanced machine learning algorithms, particularly convolutional neural networks (CNNs), the app allows farmers to capture images of affected leaves using their smartphones. These images are analyzed to identify diseases such as fungal infections, bacterial blights, viral infections, or nutrient deficiencies, providing crop-specific diagnoses and treatment recommendations. A standout feature of "Pannai Maruthuvam" is its delivery of ·guidance in Tamil, overcoming language barriers and ensuring farmers receive clear audio and video instructions on disease symptoms and· management, all tailored to the local agricultural context. Beyond disease detection, the app offers several essential features. Farmers can consult agricultural experts via live chat, voice, or video calls for personalized advice, with the option for in-person consultations if required. Recognizing the connectivity issues in rural areas, the app also provides offiine functionality, allowing users to download content, ensuring access to vital information even without internet access. The app further integrates real-time weather data and predictive models to provide proactive disease outbreak alerts based on environmental conditions, enabling farmers to take preventive measures in advance. A community forum feature fosters collaboration, enabling farmers to share experiences, seek advice, and support each other in managing crop health. With its user-friendly interface, "Pannai Marulhuvam" ensures accessibility even for farmers with minimal technological experience, supporting multiple crop types and offering localized, practical guidance. Through the integration of machine learning, expert advice, and community engagement, the app empowers farmers to improve agricultural productivity, reduce the impact of leaf diseases, and promote sustainable farming practices. This comprehensive approach positions "Pannai Maruthuvam" as a groundbreaking solution to crop disease management, designed specifically to meet the needs of Tamil Nadu's farming community .

PREAMBLE TO THE DESCRPTION
I. Technical Field
The present invention relates to a mobile application designed for agricultural purposes, with
a particular focus on detecting and managing leaf diseases in crops. By integrating machine learning
techniques, specifically for image analysis, the application aims to provide farmers with accurate and
timely identification of leaf diseases. The mobile app, named "Pannai Maruthuvam," is tailored to
meet the needs of farmers in Tamil Nadu by offering audio and video instructions in the Tamil
language, thus overcoming language barriers and improving accessibility. Additionally, the app
includes functionalities such as expert consultations, offline access, disease prediction, and a
community support platform, which collectively aim to enhance crop health, prevent disease
outbreaks, and increase agricultural productivity.
2. Background of the Invention
Agriculture plays a pivotal role in the economy of Tamil Nadu, with a large percentage of the
state's population relying on farming for their livelihood. Despite the importance of agriculture, crop
diseases-particularly those affecting leaves-pose a significant threat to crop health and can lead to
devastating financial losses if not detected and treated early. Many farmers, especially those in rural
areas, encounter multiple challenges in addressing crop diseases, including limited access to
agricultural experts, insufficient resources for proper treatment, and language barriers that make it
difficult to comprehend technical guidance available in non-local languages.
Existing agricultural solutions, such as general-purpose mobile applications or government
advisory services, often fail to address these specific needs, particularly in terms of providing
localized and language-specific assistance. Furthermore, rural farmers frequently lack the
technological expertise required to operate sophisticated apps, and poor internet connectivity in
remote regions adds to the difficulty of accessing digital resources. Thus, there is a growing demand
for an easily accessible, localized mobile solution that can empower farmers to efficiently manage
crop diseases while providing expert assistance and community support.
3. Object of the Invention
The primary objective of this invention is to develop a mobile application, named "Pannai
Maruthuvam," specifically designed to enable farmers in Tamil Nadu to detect and manage leaf
diseases in crops. The app leverages machine learning technology to analyze images of affected
leaves and provides detailed audio and video explanations in the Tamil language to guide farmers
through the disease identification and treatment process .
4. Summary of the Invention
The "Pannai Maruthuvam" app is a user-friendly mobile application tailored to assist farmers
in Tamil Nadu with the detection and management of leaf diseases across various crops. The app's
core feature is the machine learning model, trained to analyze leaf images submitted by farmers and
identify diseases or nutrient deficiencies. Upon detection, the app provides the farmer with a
diagnosis and offers detailed audio and video guidance in Tamil, describing the disease and offering
treatment steps. These treatment suggestions are specifically adapted to local agricultural practices
and crop varieties, ensuring that farmers receive relevant and practical advice.
COMPLETE SPECIFICATION
Specifications
The provided drawing illustrates the main interface of the "Pannai Maruthuvam" application. It
depicts the key functionalities, including:
I. Image Capture: The screen where farmers can upload photos of affected leaves for disease
detection.
2. Disease Diagnosis Results: The output screen showing the identified disease along with
options for accessing audio and video guidance in Tamil.
3. Navigation Menus: Options for connecting with experts, accessing the community forum,
downloading content for offline use, and checking predictive alerts for upcoming disease·
risks.
DESCRIPTION
The "Pannai Maruthuvam" app leverages state-of-the-art machine learning algorithms,
particularly convolutional neural networks (CNNs), to analyze images of diseased leaves. Farmers
can use the app to capture photos of affected leaves using their smartphone cameras, which are then
processed by the app's image recognition system. The CNN model, trained on a diverse dataset of
labeled leaf images, is capable of recognizing a wide variety of leaf diseases, including fungal
infections, bacterial blights, viral infections, and nutrient deficiencies.
Once the disease is identified, the app provides a detailed explanation in Tamil, covering the
following aspects:
• Description of the Disease: A brief overview of the disease and its potential impact on crop
health.
• Symptoms: A list of visible symptoms on the leaves and surrounding areas that confirm the
disease diagnosis.
• Treatment Methods: Step-by-step guidance on how to treat the disease, including organic
and chemical solutions, tailored to the farmer's specific crop and region.
• Preventive Measures: Recommendations on how to prevent the recurrence of the disease,
including crop rotation strategies and soil management techniques.
The audio and video tutorials are delivered in Tamil, ensuring that farmers can fully understand
the content without needing literacy or proficiency in other languages. The video tutorials are contextsensitive,
providing practical demonstrations of how to apply treatments to the crops in question.
In regions with poor internet access, the app allows farmers to download the content for offline
viewing, including diagnostic resources, treatment guides, and preventive measures.
