What kind of problem would be?

Hi Keshab Chhetri ! Could you add more photos? If possible the whole plant.

Yes. I agree with Artur. More pictures please. It seems fungal. But not like blast entirely.

Hi! Are these symptoms happening on all leaves? I would like to see pictures of the whole plant, thank you very much Keshab Chhetri 😁👍🌱

Mr. Shankara Goud M

Dear Keshab Chhetri I agree with Tufail Abbas that it is blast of rice. As advised by him azaxystrobin and copper oxy chloride can be effectively used to control the disease. Artur

In my opinion it looks like a Queima por Fertilizantes ou Pesticidas . Have you applied any product on the leaves recently?

What do you think Artur ?

I agree with you Carol. It looks like a Queima por Fertilizantes ou Pesticidas 👍

Dear Manejebem | Carol and Artur It is a clear case of fungal infection. The edges of the spot are dark , which is charecteristic of fungal infection. In case of pesticides damage , the edges of the spots does not become dark
