Defeating Gummy Stem Blight: Strategies for Cucurbit Growers
“Chlorosis of leaf margins, wilting, oozing of gum, cracking of fruits” – Are you seeing these signs in your cucurbits farm?
If yes, it’s high time to take immediate action against this highly destructive fungal disease: gummy stem blight. This fungus has the ability to spread rapidly, causing significant damage and loss to your crops. Visualize the devastating consequences of allowing this disease, caused by the pathogen Didymella bryoniae, to go unchecked. It can lead to substantial yield losses and a decline in fruit quality.
Whether you’re already engaged in cucurbit farming, or if you’re planning to venture into it, it is crucial to familiarize yourself with the signs and causes of gummy stem blight and equip you with the tools to safeguard your harvest.
Gummy stem blight symptoms can be observed on all parts of the plant except the roots.
Following are the conditions which create favourable conditions for the disease to develop and spread;
Spray or drench with Trichoderma viride or Pseudomonas or Bacillus spp, 15 days after sowing at every 15 days interval to prevent and manage gummy stem blight disease in melons and other cucurbits.
