Gummystemblight is a cucurbit-rot disease caused by the fungal plant pathogen Didymella bryoniae. Gummystemblight can affect a host at any stage of growth in its development and affects all parts of the host including leaves, stems and fruits. Daconil fungicides from GardenTech brand offer highly effective three-way protection to prevent, stop, and controlgummystemblight and more than 65 other diseases, including powdery mildew. Learn about the damage symptoms of gummystemblight, preventive measures, and control solutions to protect your crops from this fungal disease. Gummystemblight can live on seeds transported from state to state. The spores can also be spread state to state by wind. Locally, gummystemblight can be spread by asexual reproductive structures, conidia, in the gum during rains or watering. In fungicidal sprayed plots and under control, the PDI of gummystemblight (GSB) of watermelon ranged 8.50-46.50% in 2016-2017 and 6.83-44.63% in 2017-2018. In both the year disease severity was the maximum under control. Gummystemblight was first reported in 1891 in France, Italy, and the United States. It affects the leaves, stems, and fruits of all cucurbits. On fruit the disease is known as black rot. GummyStemBlight. Causal Agent. Distribution. Symptoms. Conditions for Development. Control.Control weeds and remove wild cucurbits from potential field locations. Implement a preventative fungicide spray program. Use fungicide-treated seed. There is no “silver bullet” approach for controllinggummystemblight. Key strategies for disease management include good sanitation, thorough year-end cleanup, proper pruning and growing practices, multi-cropping and proper irrigation practices. These results suggest the potential of azoxystrobin, kresoxim-methyl, E. agglomerans (B8Fr), and B. subtilis (AGS-4) applied post-inoculation to controlgummystemblight on greenhouse cucumbers. Important steps for management of gummystemblight (GSB) / black rot of cucurbits A sequence of management plans must be initiated to control GSB: 1. Seed: One source of GSB inoculum is the seed. Studies were conducted to evaluate the efficacy of Streptomyces isolates for the biological control of gummystemblight (GSB) in cantaloupes (Cucumis melo var. ‘Primo’) in south Texas. Rehn, is a disease that affects the productivity of watermelon leading to losses exceeding 40%.

ControllingGummyStemBlight on Grafted Watermelon Seedlings with Fungicides.The objective of this project was to test fungicides that controlgummystemblight in the field for efficacy on grafted watermelon seedlings in the greenhouse. Six treatments were tested to establish the effectiveness of the selected endophytic fungus on controllinggummystemblight and Fusarium wilt in muskmelons under greenhouse conditions.
