Thank you

Respected sir,

I know about this type sign frequently found on the stem of soybean. But this is not the pycnidial stage of Macrophomina. Phomopsis sp., Diaporthe phaseolorum var. sojae, and D. phaseolorum var. caulivora is responsible for this sign.

If you contradict my response then clarify please.
