摘要：

Alternanthera sessils often known as joy weed. It belongs to the family Amaranthaceae; is oneof the most predominant diseased weeds in rice fields of Devarapalli mandal West Godavari district, Andhra Pradesh. The symptoms of this disease appear as reddish pink color circular spots on the leaves. The disease severity is maximum in the month of august during kharif season. This study is mainly concerned about measurement of disease severity using visual analysis, Image J (IJ), and Leaf doctor (LD) applications. Each diseased leaf of the plant was exposed to visual assessment, Image J (IJ), and Leaf Doctor (LD) applications. The data was subjected to statistical analysis. This study indicates Leaf Doctor (LD) application is accurate, easier, and faster whereas determination of diseased leaf area with Image J (IJ) application is most suitable.
