Resistance to Azoxystrobin in the Gummy Stem Blight Pathogen Documented in Georgia

Plant Health Progress, 2004
Gummy stem blight, caused by the fungus Didymella bryoniae, is the most destructive disease of watermelon in Georgia and in many other watermelon producing areas of the U.S. The QoI fungicide azoxystrobin has been used for gummy stem blight control in Georgia since 1998.

Temporal and spatial dynamics of watermelon gummy stem blight epidemics

European Journal of Plant Pathology, 2010
The effect of the distance of initial inoculum on the intensity of watermelon gummy stem blight, caused by Didymella bryoniae, was studied in a naturally-infected rainfed commercial field. The shorter the distance from the focus, the sooner was disease onset and the earlier maximum disease levels were achieved.

Progression of Gummy Stem Blight Epidemics on Watermelon With and Without Fungicide Inputs

Plant Disease
Gummy stem blight (GSB), caused primarily by the fungus Stagonosporopsis citrulli in the Southeastern United States, affects cucurbits and is particularly destructive on watermelon. Previous epidemiological models of GSB constructed for greenhouse cucumber showed leaf wetness and temperature were the primary and secondary environmental factors ...

Chemical and Biological Treatments for Control of Gummy Stem Blight of Greenhouse Cucumbers

European Journal of Plant Pathology, 2002
Experiments were conducted to determine the effects of chemical and biological treatments on gummy stem blight of cucumber caused by Didymella bryoniae in vitro and under greenhouse conditions. Eleven strains of Bacillus subtilis, strain AGB10 of B. cereus, and strain B8Fr of Enterobacter agglomerans produced antagonistic zone against D.

Factors Promoting Pycnidia Production of Didymella bryoniae, the Causal of Gummy Stem Blight in Cucurbits

Egyptian Journal of Phytopathology, 2017
Gummy stem blight in Cucurbitacea caused by the pathogen Didymella bryoniae under high humid conditions was previously recorded in many countries. In Egypt, the disease was observed for the first time on cantaloupe grown under sprinkling irrigation system in El-Bostan (Beheira governorate).

Diagnostic Guide for Gummy Stem Blight and Black Rot on Cucurbits

Plant Health Progress, 2013
Gummy stem blight and black rot affect all commonly cultivated cucurbits, including melon, watermelon, cucumber, pumpkin, and squash. Symptoms may be found on all vegetative and reproductive parts of plants, although there is variation in susceptibility among species and horticultural types.

Fungicide Timing for Optimum Management of Gummy Stem Blight Epidemics on Watermelon

Plant Disease, 1995
During the fall of 1991 and 1993, four fungicide-application intervals were evaluated on watermelon for control of gummy stem blight, caused by Didymella bryoniae. Chlorothalonil combined with benomyl was supplied full season (six times), early season (first half of the season, three or four times), late season (last half, two or three times), or not ...
