Storing oilseeds is more difficult than storing cereal grains as they are more susceptible to quality deterioration and have limited insect control options... The decision to store oilseeds requires a planned approach, careful management and a suitable storage system... Moisture content in oilseeds must be lower than cereal grains because the oil content increases the risk of moulding and quality damage...

The Australian Government has announced additional funding of $29.7 million over six years for the CRCNPB... Grains industry biosecurity management and stored grains protection will continue to be a priority for the CRCNPB. Chief executive officer Dr Simon McKirdy says efforts will continue to extend the life of the stored-grain fumigant phosphine and to find alternatives to phosphine - particularly non-chemical options such as nitrogen... "A better understanding of how insects are surviving between harvests will also be important in improving fumigation management," Dr McKirdy says...

Forum covers carbon questions - Western regional focus.. [Photo (left) by Merredin Wheatbelt Mercury: About 50 farmers and industry people attended a carbon forum at Mukinbudin to learn what carbon policies and legislation might mean for agriculture.].. "The project will be part of phase two of the Grain & Graze national program, which covers WA's wheatbelt and targets new approaches to delivering information, products and skills to farmers to implement improved management practices," she says...

New hand-held computer technology with the potential to improve the protection of the nation's vast grains storage system, generate cost savings and enable greater market access will be trialled this summer... The Department of Agriculture and Food, Western Australia (DAFWA) is leading the Cooperative Research Centre for National Plant Biosecurity (CRCNPB) project, in association with the CBH Group, Viterra, GrainCorp Operations and several WA organisations... The outputs of this and all CRCNPB projects are shared between its participants, including the Department of Agriculture, Fisheries and Forestry, DAFWA, Queensland Department of Employment, Economic Development and Innovation, Murdoch University, CBH Group, ABB Grain Ltd and GrainCorp Operations...

A targeted mission to improve on-farm storage.. Learning how to correctly and safely store grain on farm is essential to ensure quality.. Issues covered at the workshops include monitoring and identifying pests, key hygiene sites, aeration cooling, effective phosphine fumigation, selection of storages and practical farm storage strategies that apply an integrated approach to controlling pests and maintaining quality...

In Australia, more than 80 per cent of all stored grain is treated with phosphine, which means it is the chemical most in contact with insects, creating the greatest chance for insects to develop resistance... Two projects under the CRC for National Plant Biosecurity are looking at the genetics of insect resistance to phosphine to understand the development of resistance and to rapidly identify resistant insects... One of the greatest threats to emerge is the development of resistance to phosphine in the lesser grain borer (Rhyzopertha dominica), one of the most common pests of stored grain...

Pressure testing a silo ensures it can hold gas concentrations sufficient to kill all insects at all life stages... If the silo has a slide plate outlet that has been tested empty, retest when full to make sure the pressure of the grain doesn't compromise the seal... Common places for leaks are: bottom outlet, aeration inlet seal, damaged lids (caused by the auger when lining it up to fill the silo), stretched springs on latches, between the bottom cone or base and the silo wall joint, the roof and wall joint and where the lid ring joins the roof...

Standard to seal off phosphine resistance.. A new national standard for gas-tight grain storage aims to 'knock down' the phosphine resistance in grain insects that has been gnawing at the industry since a pest beetle strain was first detected on a Queensland farm 13 years ago... Many grain silos have failed to meet the gas-tight standards required for effective fumigation, creating a serious threat to the Australian grains industry by increasing target insect pest resistance to phosphine treatments," Mr Botta says.
