Abstract
ABSTRACT
This research aims to study the incidence of disease in lowland rice tungro held in the District of West Tomohon, and lasted for 5 months from the month of November 2014 until March 2015. This study uses a survey or field observation purposive sampling with the object of research fields rice farmers in West Tomohon sub district, which is in the Village Taratara and Village Woloan.
