Soybean red crown rot: Current knowledge and future challenges

Plant Pathology, 2023
Abstract Soybean red crown rot (RCR) is caused by the soilborne fungal pathogen Calonectria ilicicola . It causes root rot, leaf senescence, early defoliation, plant wilting and even death, often resulting in a severe reduction in seed yield and quality ...

Morphological Characteristics and Molecular Identification of Calonectria ilicicola Causing Soybean Red Crown Rot

Research in Plant Disease, 2006
The 18 isolates of soybean red crown rot pathogen(Calonectria ilicicola) were isolated from infected soybean plants showing chlorosis symptom and red perithecia sign in 2002 and 2003 season in Korea. The morphological characteristics of the typical isolate SC03-15, such as macroconidia and macrovesicles in anamorph as well as perithecia, asci and ...

Histopathology of red crown rot of soybean

Journal of General Plant Pathology, 2016
Histopathological analyses of red crown rot (RCR) of soybean were performed using field-grown and indoor-grown soybean plants. These analyses revealed that soybean plants formed a periderm to prevent pathogen invasion. When a break formed in the periderm, an additional periderm newly differentiated into the inner cells and prevented pathogen invasion ...

Factors affecting red crown rot caused by Calonectria ilicicola in soybean cultivation

Journal of General Plant Pathology, 2020
Red crown rot caused by Calonectria ilicicola, a soil-borne fungus, is one of the main soybean diseases in Japan. In field surveys to understand the present status of the disease in Akita, Fukushima, Niigata, Toyama, and Nagano prefectures, survey data included the cultivation history and conditions as well as the disease ratings for each field.

Phylogenetic diversity of Calonectria ilicicola causing Cylindrocladium black rot of peanut and red crown rot of soybean in southern China

Journal of General Plant Pathology, 2017
Calonectria ilicicola Boedijin & Reitsma (anamorph: Cylindrocladium parasiticum Crous, Wingfield & Alfennas) is an important pathogen worldwide, which causes Cylindrocladium black rot (CBR) in peanut (Arachis hypogaea L.) and red crown rot (RCR) in soybean [Glycine max (L.) Merr.].

Red Crown Rot of Hop in Oregon Caused by Phomopsis tuberivora

Plant Health Progress, 2013
During July 2007, symptoms including weak growth and death of plants of cultivar Fuggle were reported by a hop grower in Marion Co., OR. Phomopsis tuberivora H.T. Güssow & W.R. Foster 1932 was consistently recovered from affected plants. Koch's postulates were fulfilled with three isolates of the fungus, establishing the pathogen and the disease ...

Assessment of Selected Commercially Available Seed Treatments on Suppressing the Effects of Red Crown Rot on Soybeans Under a Controlled Environment

Plant Disease, 2022
Calonectria ilicicola is a soilborne fungus responsible for red crown rot (RCR) in soybeans. Recently, this disease has been detected in new areas within the United States and Asia, where it has been reported to cause significant yield losses. To date, no data on the efficacy of fungicide seed treatments for suppressing RCR in soybeans are available ...

Identification of Cyprodinil + Fludioxonil to Manage Soybean Red Crown Rot Using the Microplate-Based High-Throughput Screening and Pot Assay

Plant Disease, 2023
Red crown rot (RCR), caused by the soilborne fungus Calonectria ilicicola, is an emerging soybean disease in Taiwan, and fungicide screening is desired to identify effective management for C. ilicicola. This study screened 11 fungicides, including azoxystrobin, boscalid, cyprodinil, cyprodinil + fludioxonil, difenoconazole, fluopyram, flutolanil ...

Toxic culture filtrates produced byCalonectria ilicicola, causal agent of red crown rot of soybean

Phytoparasitica, 2001
Eleven soybean cultivars with different levels of susceptibility to virulent isolate SG915 ofCalonectria ilicicola were examined for reaction to metabolites produced by the isolate. When the culture filtrate from isolate SG915 was applied to trifoliates from 11 cultivars, cvs. ‘Cajun’ and ‘Asgrow 7986’ exhibited reduced wilting severity. However, there

Effects of Glyphosate onCalonectria crotalariaeand Red Crown Rot of Soybean

Plant Disease, 1991
Surfactant- and nonsurfactant-containing commercial herbicide formulations of glyphosate were evaluated for in vitro and in vivo effects on Calonectria crotalariae and red crown rot of soybean, respectively. Rates of 0.28, 0.56, 1.12, and 2.25 kg of glyphosate per hectare, corresponding to recommended rates for weed control in soybean (Glycine max ...
