Good advice to growers: don’t accept bad advice on stored grain

Australia’s grain growers are playing a vital role in safeguarding the nation’s access to global grain markets worth more than $12 billion.

By using only registered treatments for grain and on-farm storages and adhering to label directions and rates, growers are protecting Australia’s reputation as a supplier of high quality, clean grain.

Growers and other industry personnel are being reminded not to accept any “poor advice” but continue to abide by industry regulations, as lucrative international market access would be quickly destroyed if unregistered or off-label chemicals were used in grain or grain storages.

Chris Warrick, who heads up the Grains Research and Development Corporation (GRDC) Grain Storage Extension Project, says products used for structural treatments must be registered for that purpose and accepted by the intended grain buyer.

“Do not use any product on grain or grain storage which is not registered for that purpose and always follow label directions and rates – do not accept any advice to the contrary,” Mr Warrick says.

“The risk is greater than having a load of grain rejected – chemical misuse could lead to the demise of Australia’s reputation, causing key buyers to stop importing grain from Australia.

“Caution should be exercised before using any treatment on grain or grain storages to ensure they are registered for that purpose and accepted by the market or grain buyer.”

Mr Warrick says residual chemistry from off-label application in stored grain may even find its way into other export industries, including meat and processed goods.

Grain hygiene and structural treatments are the first line of defence against insect pests, but product choice is critical.

“Diatamaceous Earth (DE) products such as Dryacide® are a non-chemical option which control all common grain storage insect pests,” Mr Warrick says.

“Because DE products have a physical effect on the insects rather than a chemical effect there is no known resistance issues.”

GRDC Manager Pests, Dr Leigh Nelson, says the GRDC and its industry partners commend growers for their responsible approach to treating stored grain.

“Our growers recognise the importance of Australia maintaining its reputation for supplying international markets with grain of the highest quality,” Dr Nelson said.

“They continue to do the right thing in terms of best practice treatment of stored grain and on-farm storages, and by doing so are protecting their livelihoods and those of all grain growers.”

To assist growers in their ongoing efforts to store and treat grain correctly, the GRDC has produced a Grain Storage GrowNotes™ publication, available at
