rice - leaves turning yellow and dying
Rice Govardhan Ecovillage, India
I have two questions:
1. The leaves at the base are turning yellow and then brown, eventually dying. its an organic cultivation. What disease is it? These symptoms are not to be seen in adjacent plot which is cultivated through inorganic fertilizers.
2. My organic cultivation is through SRI method whereas the other plot is done conventionally. at this point of time it doesn't seem that my organic field will give same output as conventionally cultivated rice plot.
please see images.

this is sheath bilght of rice causal organism is rhizoctina solani,initail symptom are shown on leave sheath near water level, on leaf sheath oval or eliptical or irregualar grey spot are formed
management-avoid excess doge of fertilizer,eliminate weed host,spray propiconazole @0.1%,hexaconazole @0.2% and seed treat with pseudomonas fluorescence@10g/kg of seed. over 6 years ago.
Thanks for your input Bibekannda. But I think it is not a sheath blight disease, it could be a nutrient deficiency. As you can see, this field is cultivated by organic way and usually compost and/or manure takes more time to decompose and release nutrients to the soil. over 6 years ago.
thank u sir for your suggestion over 6 years ago.
