In 2006~2010, leaf spot symptoms, that is, small, yellow spots that turned into dark brown-to-black lesions surrounded by a yellow halo, were observed on Cymbidium spp. in Gongju, Taean, and Gapyeong in Korea. A Fusarium species was continuously isolated from symptomatic leaves; in pathogenicity testing, isolates caused leaf spot symptoms consisting of sunken, dark brown lesions similar to the ...

Thrips-transmitted Iris yellow spot virus is an economically important viral pathogen of Allium crops worldwide. A global analysis of known IYSV nucleocapsid gene (N gene) sequences was carried out to determine the comparative population structure, spatial and temporal dynamics with reference to its genetic diversity and evolution. A total of 98 complete N gene sequences (including 8 sequences ...

Among foliar diseases Leaf spot, yellow mosaic virus (YMV) and Urd bean leaf crinkle (ULCV) are destructive of mash (Vigna mungo) in Pakistan. Incorporation resistance against biotic stress plants is traditional strategy crop improvement through breeding. Effective breeding for stresses entails readily accessible resistant germplasm. 67 genotypes were evaluated multi disease was tested two cons...

Both eyes were free of inflammation and the irides were of the blue type with scattered honey-coloured freckles. The right eye showed a pale yellow spherical mass approximately 2 mm. in diameter within the iris stroma almost midway between the pupil margin and the root of the riris in the upper temporal sector (Fig. I). Large curly new vessels coursed in the iris stroma from the periphery radia...
