Plant Disease Recognition Using ML

Abstract

Crop cultivation sustains the livelihoods of a substantial portion of households across developing economies, yet the crops on which those households depend are perpetually at risk from pathogenic infections that erode both yield volume and produce quality. Infected fields, when not addressed at the right time, translate into mounting financial strain that smallholder growers — who operate with limited financial reserves — are ill-equipped to withstand. The dominant method of spotting such infections today still relies on a farmer walking the field and judging leaf condition by eye, or waiting for an agronomist's visit — a workflow that is neither fast nor consistent enough for large-scale cultivation. Progress in deep learning has fundamentally changed what automated visual inspection can accomplish, and plant pathology diagnosis is one of the fields that has benefitted most visibly. Image-based pipelines can now scan a leaf photograph and return a disease classification in fractions of a second. Among the architectures driving this capability, Convolutional Neural Networks occupy a central role: their layered filter design allows them to extract and encode visually informative features — texture discontinuities, color anomalies, lesion geometry — without any manual specification of what to look for. We present a CNN-driven plant disease recognition system that operates on photographs of plant leaves and returns a disease label together with a confidence estimate. Our training corpus is the Plant Village benchmark collection, a large repository of annotated leaf images spanning healthy and diseased specimens across multiple crop varieties. The input pipeline applies spatial normalization, pixel rescaling, and augmentation strategies to condition the data before it reaches the network. A React.js browser interface connects end users to the model via a lightweight prediction API, enabling diagnosis without any specialist involvement. Validation results affirm that this deep learning approach surpasses rule-based image processing baselines on both accuracy and response time, and the system holds clear potential for adoption in early disease management program
