Genetic resistance is potentially one of the most cost-effective and sustainable strategies to control FLS. However, C. sojina has already demonstrated the ability to overcome resistance conveyed by single R-genes (resistance genes) of soybeans, followed by the emergence of new physiological races. -

Fungicide Sensitivity of Corynespora Cassiicola and Assessment Of
FUNGICIDE SENSITIVITY OF CORYNESPORA CASSIICOLA AND ASSESSMENT OF MANAGEMENT OF TARGET SPOT OF COTTON IN GEORGIA by: MA. KATRINA SHIELA E. LAUREL (Under the Direction of Robert C. Kemerait, Jr.) ABSTRACT Target spot, caused by Corynespora cassiicola, is a serious foliar disease of cotton in the southeastern United States. Baseline (current) isolates of C. cassiicola were tested for sensitivity to metconazole (DMI), fluxapyroxad (SDHI) and pyraclostrobin (QoI). Further work compared fungicide sensitivity of C. cassiicola isolates from cotton to isolates from other hosts. Field experiments were conducted to establish a relationship between fungicide sensitivity in laboratory experiments and fungicide efficacy in managing target spot on cotton. Based on the sensitivity distribution, all isolates tested were considered sensitive to fungicides. However, these sensitivities varied among isolates offering an early indication that resistance can happen in the future. Additionally, all fungicides reduced disease severity and premature defoliation; however, Priaxor (pyraclostrobin + fluxapyroxad [QoI + SDHI]) proved to be most effective. Results from this study can help optimize fungicide sensitivity monitoring practices in an effort to improve fungicide use patterns for optimum disease management.

Botryosphaeria Dothidea
Hu et al. IMA Fungus (2019) 10:3 https://doi.org/10.1186/s43008-019-0008-4 IMA Fungus RESEARCH Open Access Comprehensive analysis of full genome sequence and Bd-milRNA/target mRNAs to discover the mechanism of hypovirulence in Botryosphaeria dothidea strains on pear infection with BdCV1 and BdPV1 Wangcheng Hu1,2,3†, Hui Luo1,2,3†, Yuekun Yang1,2,3, Qiong Wang1,2,3, Ni Hong1,2,3, Guoping Wang1,2,3, Aiming Wang4 and Liping Wang1,2,3* Abstract Pear ring rot disease, mainly caused by Botryosphaeria dothidea, is widespread in most pear and apple-growing regions. Mycoviruses are used for biocontrol, especially in fruit tree disease. BdCV1 (Botryosphaeria dothidea chrysovirus 1) and BdPV1 (Botryosphaeria dothidea partitivirus 1) influence the biological characteristics of B. dothidea strains. BdCV1 is a potential candidate for the control of fungal disease. Therefore, it is vital to explore interactions between B. dothidea and mycovirus to clarify the pathogenic mechanisms of B. dothidea and hypovirulence of B. dothidea in pear. A high- quality full-length genome sequence of the B. dothidea LW-Hubei isolate was obtained using Single Molecule Real- Time sequencing. It has high repeat sequence with 9.3% and DNA methylation existence in the genome. The 46.34 Mb genomes contained 14,091 predicted genes, which of 13,135 were annotated. B. dothidea was predicted to express 3833 secreted proteins. In bioinformatics analysis, 351 CAZy members, 552 transporters, 128 kinases, and 1096 proteins associated with plant-host interaction (PHI) were identified. RNA-silencing components including two endoribonuclease Dicer, four argonaute (Ago) and three RNA-dependent RNA polymerase (RdRp) molecules were identified and expressed in response to mycovirus infection. -

Bag X5017, Stellenbosch, 7599, South Africa *Correspondence: Pedro W. Crous, [email protected] Abstract: The Capnodiales incorporates plant and human pathogens, endophytes, saprobes and epiphytes, with a wide range of nutritional modes. Several species are lichenised, or occur as parasites on fungi, or animals. The aim of the present study was to use DNA sequence data of the nuclear ribosomal small and large subunit RNA genes to test the monophyly of the Capnodiales, and resolve families within the order. We designed primers to allow the amplification and sequencing of almost the complete nuclear ribosomal small and large subunit RNA genes. Other than the Capnodiaceae (sooty moulds), and the Davidiellaceae, which contains saprobes and plant pathogens, the order presently incorporates families of major plant pathological importance such as the Mycosphaerellaceae, Teratosphaeriaceae and Schizothyriaceae. The Piedraiaceae was not supported, but resolves in the Teratosphaeriaceae. -

Alumnos de Fitopatología de la Facultad de Ciencias Agropecuarias (UNER). Oro Verde, Junio 2010 . Introducción A nivel mundial su distribución es amplia, diseminándose en las regiones sojeras mas importante del mundo, produciendo daño en regiones tropicales y subtropicales. Fue citada por primera vez en Japón en 1915 y se encontraron 12 razas en Estados Unidos y 22 en Brasil (INTA EEA Marcos Juárez, Agrobit) La MOR es una enfermedad fúngica que presenta una alta variabilidad ya que existen diferentes razas, y fué reportada por primera vez en la zona centro de Argentina en 1983 (Giorda y Justh, 1983) y en la zona norte en la campaña 1997/98 (Ploper et al., 1999). En el ciclo 1999/2000 se registró una severa epifitia en la provincia de Tucuman, con pérdidas del 48%. Se continuó utilizando cultivares susceptibles pero de maduración temprana y en zona sin antecedentes de la enfermedad, sin que se presentara otra epifitia de la enfermedad. En el 2002/2003 se registraron niveles altos en el NOA, y centro de la provincia de Córdoba. (Ploper et. al., 2010) En diciembre de 2008, MOR se detecta en lotes del sudeste de la provincia de Córdoba con niveles de incidencia muy amplios, desde trazas hasta el 100% de las hojas infectadas y severidades que no superaban el 10% en los casos más graves. Según un relevamiento realizado en los departamentos Unión y Marcos Juárez, la enfermedad progresó hasta alcanzar niveles de prevalencia e incidencia del 100%, con severidades que iban desde trazas hasta el 90%, dependiendo del cultivar y la fecha de siembra (Distéfano y Gadbán, 2009). -

Abstract Cercospora (Mycosphaerellaceae) is a large genus of fungi comprising many important plant pathogens. In recent years DNA-based studies have revealed multiple genera of cercosporoid fungi being poly- and paraphyletic. Among these genera, the genus Cercospora has always been perceived as monophyletic. In the present study, phylogenetic inferences based on partial gene sequences of the LSU, ITS, ACT, TEF1-α and HIS loci, elucidated a cercospora-like taxon from Ammi majus to cluster in a clade apart from Cercospora s. str. In spite of numerous Cercospora spp. presently known from their DNA se- quence data, this collection represents the first concrete evidence to the fact that the morphological characters previously at- tributed to Cercospora s. str. evolved more than once in the Mycosphaerellaceae. The genus Neocercospora is subsequently introduced to accommodate the Iranian taxon occurring on A. majus.
