Watermelon leaves are necrotic and blighted leaf margins

General    Burma

Please help me, I have a problem with my watermelon field. I don't know what is the reason, disease or deficiency. Please provide the solution to this problem and a possible explanation about this.

You should have uploaded the image of upper surface as asked by Dr. Ravishankar Narayana.

I think this is Alternaria Leaf Spot caused by Alternaria cucumerina. This occurs when the weather is wet for long period of time. Spraying chemicals like mancozeb (0.2%) or copper hydroxide would help keep the disease in check. Please visit https://www.farmingindia.in/watermelo... for more information regarding this disease.
