Six species of insects and a rust fungus have been successfully established for biocontrol of the weed Parthenium hysterophorus L. in Queensland, Australia. Effectiveness of biocontrol insects was evaluated at two properties in Queensland during 1996-97 based on an exclusion experiment using insecticides. Parthenium-infested plots with and without biocontrol insects were sampled at monthly inte...

Species of Sphaerellopsis (sexual morph Eudarluca) are well-known cosmopolitan mycoparasites occurring on a wide range of rusts. Although their potential role as biocontrol agents has received some attention, the molecular phylogeny of the genus has never been resolved. Based on morphology and DNA sequence data of the large subunit nuclear ribosomal RNA gene (LSU, 28S) and the internal transcri...

Barilli E., Sillero J.C., Prats E., Rubiales D. (2014): Resistance to rusts (Uromyces pisi and U. viciae-fabae) in pea. Czech J. Genet. Plant Breed., 50: 135–143. Pea is the second most important food legume crop in the world. Rust is a pea disease widely distributed, particularly in regions with warm, humid weather. Pea rust can be incited by Uromyces viciae-fabae and by U. pisi. U. viciae-fab...

Soybean is one of the most important crops in Brazil and continuously generates demands for production technologies, such as cultivars resistant to diseases. In recent years, the Asian rust fungus (Phakopsora pachyrhizi Syd. & P. Syd 1914) has caused severe yield losses and the development of resistant cultivars is the best means of control. Understanding the genetic control and estimating para...

Based on the morphological study of specimens of rust fungi collected during 2002-2003, a contribution is made to the rust fungus flora of Hamedan province: Uromyces inaequialtus var. ecbatanensis is described as new taxon. Melampsora allii-fragilis and Uromyces acantholimonis var. zagrosica are new reports for Iran. New observations on already known species were made: the aecia of Melampsora e...
