Crop Disease Management
Weed Management
Irrigation and Soil Management
AI, particularly deep learning with CNNs, has significantly advanced crop disease diagnosis. Early research used fuzzy logic and ANNs for detection, but recent studies show CNNs achieving near-perfect accuracy (up to 99.76%) in identifying diseases from visual data like leaf images. Future directions involve integrating environmental factors and laboratory techniques for robustness.
99.76%
Highest Disease Detection Accuracy (Tomato leaves)
| AI Technique | Application | Accuracy/Benefit |
|---|---|---|
| Fuzzy Logic | Grading leaf disease, forecasting plant disease | Effective for classification and forecasting |
| ANN | Identify tomato diseases, spectral prediction of fungus | Up to 100% accuracy in specific tasks |
| CNN (Deep Learning) | Detect/diagnose plant diseases from leaf images (e.g., tomatoes, rice, cotton, olive) | Up to 99.76% accuracy, robust in recent studies |
| Transformer Learning | Plant disease classification (wheat rust, rice leaf disease) | Outperformed CNNs of similar complexity |
| Meta Deep Learning | Identify cotton leaf diseases | Outperformed custom CNNs, VGG16, ResNet50 (98.53% accuracy) |
Real-time Olive Tree Disease Detection
Researchers developed an optimized deep CNN based on MobileNet architecture for classifying diseases in olive trees. The model was trained with 5,571 images across 6 disease classes.
Impact: Achieved a 100% accuracy rate with fine-tuning, significantly improving disease management for olive groves. Without data augmentation, it reached 92.59% accuracy.
AI is critical for efficient weed control, minimizing herbicide use and environmental impact. Early approaches involved ANNs and fuzzy logic for recognition, while deep learning (especially CNNs and Vision Transformers) now achieves high accuracy (up to 99%) in real-time weed detection and classification from aerial and ground images, even with plant overlap. Challenges include distinguishing live vs. dead weeds and robust hardware integration.

| CNN (Deep Learning) | Weed detection in various crops (maize, soybean, cereal), pixel-wise classification | Up to 99% accuracy, handles plant overlap, used in robotic control |
| Vision Transformer (ViT) | Classification of weeds and crops using high-resolution UAV images | Outperformed CNN-based models like ResNet and EfficientNet |
AI optimizes water and nutrient use by classifying soil types, predicting moisture and rainfall, and managing aquaponic environments. Techniques range from ANNs for soil texture prediction and drip irrigation estimation to machine learning (Random Forest, XGBoost) and deep learning (LSTM) for precise soil moisture forecasting and irrigation water quality indices. The models need to integrate anthropogenic factors and environmental contaminants for comprehensive predictions.
