Loop-Mediated Isothermal Amplification for the Rapid Detection of the Mutation of Carbendazim-Resistant Isolates in Didymella bryoniae [PDF]

Agronomy, 2022
Gummy stem blight (GSB) caused by Didymella bryoniae (D. bryoniae) is a worldwide fungal soil-borne disease that can cause severe yield reduction of watermelon. To shorten the monitoring time of carbendazim-resistant strains of D.

Resistência de Didymella bryoniae a fungicidas no Brasil [PDF]

Fitopatologia Brasileira, 2006
O crestamento gomoso do caule (Didymella bryoniae) é uma das mais importantes doenças da melancia (Citrullus lanatus) no mundo. O controle químico, embora amplamente adotado, nem sempre pode impedir o progresso da doença no campo. A resistência do agente causal a alguns ingredientes ativos foi relatada na Europa, Japão e nos Estados Unidos, porém ...

Reaction of melon genotypes to Didymella bryoniae (Fuckel) Rehm [PDF]

Chilean journal of agricultural research, 2017
ABSTRACT The cultivation of melon (Cucumis melo L.) in greenhouses has contributed to the increased incidence of fungal diseases, particularly gummy stem blight caused by Didymella bryoniae (Fuckel) Rehm. This disease is currently considered the main disease affecting this crop, causing conditions such as water soaked seedlings, and stem and fruit ...

Net melon resistance to Didymella bryoniae according to grafting and potassium levels [PDF]

Summa Phytopathologica, 2012
Chemical control of the fungus Didymella bryoniae, the causal agent of the disease gummy stem blight in melon, is frequently inefficient; thus, alternatives such as grafting and nutrition must be studied. Rootstocks and potassium levels were tested aimed at controlling this disease in net melon under protected environment.

Effects of deficit irrigation and biostimulants on melon productivity and quality in semi-arid conditions. [PDF]

J Sci Food Agric
Abstract BACKGROUND Water scarcity and soil salinization are major constraints to irrigated agriculture in semi‐arid regions, affecting crop productivity and fruit quality. Combining deficit irrigation with biostimulant application has emerged as a promising strategy to improve water use efficiency and plant stress tolerance.

Stagonosporopsis cucurbitacearum Effector Protein ScAA9 Contributes to Virulence and Triggers Plant Immune Responses. [PDF]

Mol Plant Pathol
The AA9 family protein ScAA9 of Stagonosporopsis cucurbitacearum plays dual roles as both a virulence factor for infection and a PAMP for host immune manipulation, highlighting the complexity of S. cucurbitacearum–host interactions. ABSTRACT Fungal pathogens secrete cell wall‐degrading enzymes that either act as virulence factors or are perceived by ...

Selection of melon genotypes with resistance to Didymella bryoniae using a diallel approach

Acta Scientiarum. Agronomy, 2019
The development of melon lines resistant to gummy stem blight (GSB) is an important strategy for decreasing losses caused by this disease. Thus, selecting the best parents for such a goal is essential.
