KORELASI PENYAKIT VIRUS TUNGRO DENGAN BERBAGAI JENIS WERENG PADA TANAMAN PADI (Oryza sativa) Di JAWA TIMUR
ABSTRACT: The objective
of research is to know
the correlation between
Tungro disease and various
leafhopper at 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 . Data analysis
was based on the intensity of tungro disease, the
frequency of rainy day and rainfall
per month, pattern
of planting, population
of green leafhopper,
as well as competitor
insect as natural
enemy. Correlation and
multiple regression analysis
was used to make epidemic model.
The results of this study indicated that epidemic model of tungro disease with
linear regression was Y= 641.659 + 1.925 ( Rainfall + 17.815 ( Green leafhopper))
+ 30.014 (
Brown leafhopper) +
60.493 ( Zigzag
leafhopper) - 59.444 (
spider) - 122.425
( Rain day)
( R =
0.988). This model
significantly can explain
correlation between rainfall, rainy day,
vector insect to the severity of tungro disease at paddy crop.
