GroundCover Supplement – Grain Storage (Issue 156, Jan–Feb 2022)
Explore the latest grain storage research, fumigation practices, aeration systems, and on-farm storage innovations featured in the GroundCover Supplement: Grain Storage (Issue 156, Jan–Feb 2022). This edition highlights practical strategies helping Australian growers protect grain quality, manage phosphine resistance, improve storage efficiency, and maximise long-term profitability.
Continue readingHow good are stored grain protectants? (GRDC Groundcover Supplement)
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.
Continue readingLentil storage and the colour of money (GRDC Groundcover Supplement)
Lentil storage study to bring cold, hard facts to hot issue of safeguarding grain quality. Storing lentils on-farm can help growers streamline logistics and target better prices. However, the impact of storage on important market traits such as colour, cooking quality and germination is still a bit of a mystery.
Continue readingPhosphine curbs cowpea weevils in stored pulses (GRDC Groundcover Supplement)
A new study sheds light on the efficacy of phosphine control of cowpea weevil, or bruchids, in mungbeans and chickpeas.
Continue readingSulfuryl fluoride can break phosphine resistance (GRDC Groundcover Supplement)
Using an alternate fumigation chemical to break the development of insect pest resistance will help protect the efficacy of phosphine fumigation
Continue readingProbing phosphine resistance in rusty grain beetle (GRDC Groundcover Supplement)
Resistant rusty grain beetles, one of the flat grain beetles, have been found throughout the grain supply chain, suggesting the need for adoption of area-wide integrated pest and resistance management.
Continue readingUsers must heed rising phosphine resistance (GRDC Groundcover Supplement)
Australian growers have relied heavily on phosphine fumigation to disinfest stored grain and meet market expectations for high-quality grain with nil tolerance to insects. However, reliance on one chemical over a long period of time has led to resistance.
Continue readingPhosphine venting and delivery limits require more research (GRDC Groundcover Supplement)
The practice of requiring a phosphine gas reading of less than 0.3ppm in a spear sample taken from within the grain threatens costly rejection of truckloads of grain, including for operators who are following phosphine label directions.
Continue readingBoosting on-farm storage with bags and bunkers (GRDC Groundcover Supplement)
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.
