This paper gives overview of Different plant leaf diseases and also analysis different techniques. In paper show various grouping strategies that can be utilized for plant leaf infections characterization. Distinguishing proof of side effects of illness by unaided eye is hard for rancher. Yield insurance in enormous casings is finished by utilizing electronic picture preparing procedure that can identify sick leaf utilizing shading data of leaves. There are so numerous grouping strategies, for example, k-Nearest Neighbor Classifier, Probabilistic Neural Network, Genetic Algorithm, Support Vector Machine, and Principal Component Analysis, Artificial neural organization, Fuzzy rationale. Choosing a grouping strategy is consistently a troublesome undertaking on the grounds that the nature of result can fluctuate for various information. Plant leaf illness arrangements have wide applications in different fields
