Data on incidence of pestldisease and resulting yield loss are necessary for research prioritization and technology intervention but are not col- lectedlreported along with the official statistics on crops. The required information is therefore generated by conducting sample surveys. Results on earlier surveys conducted by CPCRI on coconut pests and disease were made use of in analyzing their usefulness for applications in similar situations. The organizational aspects of surveys such as criteria for stratification. preparation of sampling frame, selection of units, construction of estimators, organization of field work etc. were examined , in relation to suitability under respective contexts.enCoconutpestdisease infestationyield lossArticle
