The campaign to show the value of drying and cooling to improve grain quality has moved into packing and trading businesses across Queensland and northern New South Wales.

The third training day for packing shed managers and staff, organised by Queensland's Department of Primary Industries and the Australian Mungbean Association, was held in Narrabri earlier this month.

The previous two training workshops were at the Central Queensland Seeds packing shed at Goovigen, near Biloela, and at Janmar Grains, Toowoomba. All three were led by QDPI stored grain development officers, Philip Burrill and Ken Bullen.

"Ten staff from three operations ­ CQ Seeds, Selected Seeds and Sid Allenden ­ attended the Goovigen training day while the 15 who attended the day in Toowoomba came from eight packing sheds," Mr Burrill said.

"They were Jammar Grains, Toowoomba, Mt Tyson Seeds, Champion Seeds, Millmerran, Selected Seeds, Pittsworth, Bean Growers, Kingaroy, B& L Seed Graders, Dalby, A& B Grains , Oakey and Associated Grains / Gosden Jorgensen Seeds, Dalby.

"At Narrabri, the training day was held at the CANZAC Pulse Processors's plant, with staff also attending from Global Grains Ag Services, Austgrains International , Canterbury Seed Trading and NSW Agriculture."

Mr Burrill said the Mungbean Association's involvement in the training program were another step in its implementation of a five year Strategic Plan to grow the industry and improve its image in international markets through a focus on quality product.

QDPI had been a lead organisation in a national project designed to convince all sectors of the grains industry of the value of cooling and aerated drying in improving grain quality and marketability.

The project built on the success of an earlier campaign to convince the industry of the need for safe and efficient use of the popular grain fumigant, phosphine.

Both projects were supported by the Grains Research and Development Corporation (GRDC) and involved grain storage experts from the state agricultural departments.

"The Goovigen, Toowoomba and Narrabri training days included sessions on the identification and basic biology of grain insects, grain storage and handling equipment, management of aeration, grain hygiene and chemical and physical and hygienic control measures for insects and fumigation," Mr Burrill said.

"The fumigation session focused on the safe use of phosphine to treat grain in stacked bags as well as silos, with an emphasis on the need to monitor concentrations of the chemical."
