Cor­rect grain stor­age

Warwick Daily News - South West Queensland Rural Weekly - - News -

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 in 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” re­gard­ing treat­ments for grain stor­ages but con­tinue to abide by in­dus­try reg­u­la­tions and prod­uct la­bels, as lu­cra­tive in­ter­na­tional mar­ket ac­cess would be jeop­ar­dised if un­reg­is­tered or off-la­bel chem­i­cals were used.

Chris War­rick, who heads up the Grains Re­search and De­vel­op­ment Cor­po­ra­tion 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 in grain stor­ages which is not reg­is­tered for that pur­pose and al­ways fol­low la­bel di­rec­tions and rates – do not ac­cept any ad­vice to the con­trary,” Mr War­rick said.

Mr War­rick said 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 prod­ucts such as Dry­acide are a non-chem­i­cal op­tion which con­trol all com­mon grain stor­age in­sect pests,” Mr War­rick said.

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

GRDC man­ager pests, Dr Leigh Nel­son, said the GRDC and its in­dus­try part­ners com­mend grow­ers for their re­spon­si­ble ap­proach to treat­ing grain stor­age struc­tures.

“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 on-farm stor­ages, and by do­ing so are pro­tect­ing their liveli­hoods and those of all grain grow­ers.”

GRDC has pro­duced a pub­li­ca­tion to as­sist grow­ers. Visit
