How good are stored grain protectants?
Resistance monitoring of key insect pests has shown that combined grain protectants are a valuable integrated pest management tool for stored grain.
Up to 30 per cent of freshly harvested grain is treated with contact insecticides – or grain protectants – before being placed into storage.

Phosphine curbs cowpea weevils in stored pulses
Key points
– Cowpea weevils – or bruchids – are an important insect pest in stored pulse crops in tropical and subtropical Australia
They can be effectively controlled using label rates of phosphine fumigant in sealed silos over a minimum period of seven days
– No major differences in tolerance to phosphine were identified in 15 populations collected from multiple Queensland locations

Sulfuryl fluoride can break phosphine resistance
Key points
– Rotating phosphine fumigation with sulfuryl fluoride will protect against the development of phosphine resistance
– Sulfuryl fluoride can only be purchased and applied by licensed fumigators

Grain Quality
Lentil storage and the colour of money
Key points
– A new study is investigating the impact of high temperatures and high moisture content on lentil storage to help growers protect grain quality
– Important quality traits such as seed coat colour (redness), germination efficiency and cooking quality were adversely affected by inappropriate storage conditions in as little as four months

Probing phosphine resistance in rusty grain beetle
Key points
– Strong resistance to phosphine in rusty grain beetle has increased substantially since the first resistant population was discovered in 2007
– The rusty grain beetle is mobile and resistant populations are present across the full spectrum of the grain supply chain
– Area-wide integrated pest and resistance management has the potential to suppress this problematic species indefinitely

Users must heed rising phosphine resistance
Key points
– Strong resistance to phosphine in stored grain insects has both increased and spread over the past decade, with more detections in eastern Australia than Western Australia
– Misuse of phosphine, particularly in unsealed storages, appears to be the main reason for the development of strong resistance

Phosphine venting and delivery limits require more research
Key points
– Testing phosphine residue in trucks at receival sites is required for operator safety and label compliance
– Sampling and testing methods require further research and development to avoid penalising those doing the right thing
– Using a phosphine meter on farm is the surest way to avoid truckloads being rejected

Boosting on-farm storage with bags and bunkers
With care, bags and bunkers can provide a practical solution to the harvest logistics challenge.
High-quality sealed silos offer top-of-the-range storage, but the boom in demand for on-farm storage means growers are also exploring cheaper options to expand capacity.
Bags and bunkers have become a popular, more affordable choice, but growers need to be on their toes to avoid costly failures with these temporary storage solutions.

Top tips for grain storage success
Take a sneak peek at some of GRDC’s storage extension team’s favourite systems.
The grain storage extension team regularly meets growers and industry participants on-farm to run workshops and provide specialist advice. Examples of well-laid-out facilities, smart features, ideas and innovations are highlighted here to help inspire other growers who are investing in grain storage infrastructure.
