The Grains Research and Development Corporation (GRDC) is warning that with parts of Australia still experiencing warm temperatures, while others are getting high rainfall, growers must be particularly mindful of maintaining good grain quality and reducing pest infestations in grain stored on farms.

Queensland Department of Agriculture, Fisheries and Forestry development agronomist Philip Burrill said rapidly reducing the temperature of stored grains after harvest could limit chances of grain pest problems as well as reducing mould development and protecting planting seed germination and vigour.
The release of the latest Grain Storage with Philip Burrill video from the GRDC shows how aeration controllers can make aeration cooling systems work more effectively and reliably for growers wanting the best out of their system.
“The grain storage video is a great resource for growers.
“I explain step-by-step how an aeration controller can work to protect your grain by selecting the optimum fan run times to give growers a great result and maintain the quality of all stored grain,” Mr Burrill said.
Conditions during the late summer and early autumn months still call for growers to make good use of aeration cooling systems for their on-farm storages to minimise warm grain temperatures.
Even with rain and high humidity, a well-managed aeration cooling system will select the best ambient air available to bring grain temperature towards 20 degrees celsius and below.
This slows or stops the storage pests life cycle resulting in significantly lower numbers.
The Grain Storage with Philip Burrill video is available for free download on the GRDC website at www.grdc.com.au/GRDC-Video-UsingAerationControllers.
