Research ArticleOpen accessEvery word in the titleMorphological Characteristics and Pathogenicity of Synchytrium psophocarpi (Rac.) Baumann Associated With False Rust on Winged BeanAbdollah Karami, Zainal Abidin Mior Ahmad, Kamaruzaman SijamProblem statement: Winged bean (Psophocarpus tetragonolobus L.) is an important tropical legume in countries like Malaysia due to its potential as a high protein value crop. However, bright-orange pustules observed on the veins of young leaves, stems, pods and sepals depict symptoms of false rust disease on beans. The causal agent of this disease has been found to be Synchytrium … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 9,577 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsSome Effects of Abiotic Stress on Infection of Dyer’s Woad (Isatis tinctoria L.) by Puccinia thlaspeos C. Schub.: Implications for Biological ControlElizabeth Thomas, Bradley Ray KroppProblem statement: The rust pathogen, Puccinia thlaspeos, is being studied as a potential biocontrol agent for the noxious weed dyer’s woad. Although its disease etiology is well understood, very little has been learned about the effect of environmental stresses on infection. Approach: Dyer’s woad plants were exposed to different levels of oxidative stress, salinity stress, osmotic stress, dehydration, and cold … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,715 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIntegrated Management and Fungicide Efficacy of Foliar Diseases in Spring Wheat in KazakhstanNadira Sultanova, Yerlan Dutbayev, Gulzada Abisheva et al.Spring wheat (Triticum aestivum L.) is a key economic crop in Kazakhstan. This study aimed to identify genetic sources conferring resistance to major foliar diseases and to quantify the contribution of fungicide application to yield stability. Field experiments conducted in 2024 assessed the resistance of 36 spring wheat genotypes, 17 common wheat and 19 durum wheat (T. durum Desf.), to … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 17 Jul 2026 · 961 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImmunological Characteristics of Winter Wheat Lines with Resistance to Rust Diseases in KazakhstanSaltanat Bakytzhanovna Dubekova, Amangeldy Taskalievich Sarbaev, Aikerim Asylbekkyzy Ydyrys et al.The growing spread of particularly dangerous diseases (variations of rust) in the grain-bearing countries raises fears of the harmfulness of phytopathogens increasing. In the years favorable for their development, a sharp decrease in the productivity of the ear and the quality of the grain is observed. The high potential of the pathogen to produce new aggressive disease variations makes most … …OnLine Journal of Biological Sciences, Vol. 21, Issue 4 · 17 Jan 2022 · 5,969 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSuppression of Salicylic Acid-Mediated Plant Defense Responses During Initial Infection of Dyer's Woad by Puccinia thlaspeosBradley R. Kropp, Elizabeth ThomasProblem statement: Puccinia thlaspeos is a microcyclic rust pathogen that is being investigated as a potential biocontrol agent of the noxious weed, dyer’s woad (Isatis tinctoria). Although, the initial events in the colonization of dyer’s woad by the rust pathogen has been elucidated using scanning electron microscopy and PCR, little is known regarding the susceptibility response of this plant to … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 8,033 accessesView PDF Cite
