Sheath blight of rice (Oryza sativa L.) is a major rice disease throughout the world including the southern United States. This disease, which is caused by Rhizoctonia solani Kühn (teleomorph: Thanatephorus cucumeris (Frank) Donk), was first reported in 1910 and now occurs throughout temperate and tropical production areas, being most prominent where rice is grown under intense, high-fertility ...

Late blight of potato (Solanum tuberosum L.), incited by Phytophthora infestans (Mont.) de Bary, is a devastating disease affecting tuber yield and storage. Recent work has isolated a resistance gene, RB, from the wild species Solanum bulbocastanum Dun.

This paper presents a pattern recognition system for the identification of the vegetable crops diseases from images. The proposed system is based on three main phases: Segmentation, feature extraction and classification. The segmentation of the images is carried out using k-means clustering method. Then, three type of features are extracted from the segmented images including color, texture and...
