PSDMGM
Burkholderua glumae is one of the most severe seed-borne bacterial diseases of rice in the world. It can also spread between plants via rain splash or irrigation. Warm, humid conditions, especially during flowering, greatly enhance disease transmission and severity.

Disease is known to cause discoloration of rice grain and bacteria is readily recovered. Data on actual seed transmission is primaily from artificially inoculated plants and evidence of seed transmission is vague, Research from Japan indicates that bacteria on seed may contribute to movement of the disease.
