Measurement of damaged leaf area caused by leaffolder in rice

Padmavathi Chintalapati, Sumalatha Javvaji and Katti Gururaj

Foliage feeding insects are one of the most important guilds of pests in rice that cause significant yield losses. Rice leaffolder feeding on the foliage by scraping green mesophyll tissue leads to transparent membranous patches that are highly visible and triggers farmers to go for the insecticide application. Measurement of such type of feeding is important to know the host-pest interactions for the management of leaf feeders. In the present paper, leaf area damaged by rice leaffolder was assessed by different traditional and modern technologies like Image J program and Compu Eye, Leaf and symptom area software. The estimates had significant linear relationship with the estimates of graphical method. Of the various methods assessed for the estimation of the damaged leaf area, ImageJ software was found efficient, less time consuming and easy to operate for processing a large number of samples.
