Monograph on Estimation of Incidence of Crop Pests and Diseases and Yield Losses

摘要

It is a known fact that the pests and diseases cause considerable crop losses in every season in this country, but reliable and objective estimates of incidence of pests and diseases and also crop losses in quantitative terms are not available. This monograph will serve as guidelines to the research workers for conducting the sample surveys for estimation of incidence of pests and diseases and consequent quantitative crop losses.
