Epidemiology of Viral Diseases on Green Pepper Cultivated at Kamisu, Ibaraki Prefecture

Abstract

In 1994, field surveys of viral diseases on green pepper plants were conducted at Kamisu, Ibaraki Prefecture. Infected leaves were collected from 15 locations, and the viruses were identified using both inoculation tests and morphological observations with an electron microscope. A total of three viruses was isolated. Tobacco mosaic virus (pepper strain) occurred in all locations, but cucumber mosaic virus (ordinary strain) and tomato spotted wilt virus (ordinary strain) occurred at only 3 and 2 locations, respectively.
