Riverland and Mallee grain growers are being warned of a potential increase in the risk of some soil borne diseases in 2019 as we close out a dry growing year.
A lack of rainfall has reduced the breakdown of cereal stubbles in pulse and oilseed break crops, promoting the risk of disease next season.
Rainfall to date for many parts of the state is well below average with Loxton only recording 134mm of rain for 2018 as opposed to the 30 year average of 260mm.
Two cereal diseases that can cause issues in areas with below average rainfall are Rhizoctonia root rot as well as crown rot
Alan McKay, the leader of SARDI’s Soil Biology said the risk of disease in 2019 will be heightened where growers decide to sow wheat back into this year’s failed wheat crops.
