First Report on Fusarium Wilt of Zucchini Caused by Fusarium oxysporum, in Korea
نویسندگان
چکیده
Fusarium wilt of zucchini in Jeonju, Korea, was first noticed in May 2013. Symptoms included wilting of the foliage, drying and withering of older leaves, and stunting of plants. Infected plants eventually died during growth. Based on morphological characteristics and phylogenetic analyses of the molecular markers (internal transcribed spacer rDNA and translation elongation factor 1α), the fungus was identified as Fusarium oxysporum. Pathogenicity of a representative isolate was demonstrated via artificial inoculation, and it satisfied Koch's postulates. To our knowledge, this is the first report of F. oxysporum causing wilt of zucchini in Korea.

Fusarium wilts of strawberry, caused by Fusarium oxysporum f. sp. fragariae, is a serious soil-borne disease. Fusarium wilt causes dramatic yield losses in commercial strawberry production and it is a very stubborn disease to control. Reliable chemical control of strawberry Fusarium wilt disease is not yet available. Moreover, other well-known F. oxysporum have different genetic information fro...

Fusarium wilt diseases caused by the fungus Fusarium oxysporum lead to significant yield losses of crops. Biocontrol agents such asTrichoderma viride , Trichoderma harzianum and Pseudomonas fluorescens are applied to control Fusarium wilt of Arachis hypogaea. Experiments were conducted on the effect of culture filtrates of T.viride (1%), T.harzianum (1.5%), and P. fluorescens (2%) on biochemica...
