Minor Pest Description
Immature, green fungal bodies (sori) larger than the seed develop on panicles during grain fill. A single fungal body (sorus) develops per floret. As grain matures, sori change in colour from green to dark brown. Sori are filled with dark spores. Infection takes place at temperature range of between 21 and 31°C, and at relative humidity greater than 80%. The disease is spread by wind-borne spores and rain.
