    Abstract

    The objective of research is to get Model Epidemic Disease of Virus of Tungro ~t paddy crop in some sub-province East Java. Making of epidemic model conducted by using obtained data of laboratory Perception of Pest and Disease of Crop Food and Horticulture and also Report Observer of Pest Disease . Kinds of tabulation data is virus attack data of tungro, rain day and rainfall, pattern plant, population ofwereng green, insect-ofkompetitor natural enemy and. To get a model, data analysed to use correlation analysis apd of regresi doubled. Result of research indicate that epidemic model disease of virus oftungro in form of linear regression Y= 641.659 + 1.925 (Rainfall + 17.815 ( Green Wereng» + 30.014 ( Brown Wereng) + 60.493 ( Zigzag Wereng) -59.444 ( spider) - 122.425 ( Rain day) ( R = 0.988). This model can explain relation manifestly between rainfall factor, rain day, vector insect and of competitor to disease severity of virus tungro at paddy crop.
