Stem rot of rice


Stem rot is a fungal disease found in rice. It causes black lesions commonly located around water level on the stem of the plant and is often first noticed around panicle initiation (PI).

Stem rot appeared in the MIA in 1995.  A large number of farms were affected, but no major yield losses were experienced. In 2017 there was a similar occurrence, with a number of properties reported to have stem rot in the Finley area.
