Review on the Techniques used for Identification of Diseased Leaves

In India, 65% of the people have adopted agriculture for their primary source of income. Several vital factors that affect the farmers are natural calamities and disasters such as unpredicted rain, floods, storm, drought, etc. Added to these one of the major issues faced in agriculture domain is in plant pathology. The identification and verification of plant diseases is a serious concern which needs to be treated well for increasing the yield, plant growth and quality. Many researchers, scientists and scholars have greatly contributed towards plant disease identification. However, still we see many drawbacks such as accuracy in the end results, false acceptance and false rejection problems. The main purpose of this work is to provide a detailed analysis and comparison on existing techniques versus the current trend techniques. This review will help the researchers to choose the adequate technique or method for future use. In this paper, the results of several methods used to identify diseases in leaves have been reviewed strenuously
