The Marshalls say biosecurity is about alert observation and ensuring adherence to practices such as hygiene procedures in order to minimise the risk of threats - diseases, pests and weeds - entering and establishing on-farm... They grow wheat, barley, canola, peas, lupins and oats along with lucerne and clover pasture for livestock and are keen to keep out weeds that may affect their crop production... The noxious weed spiny burrgrass is a concern for sheep production at 'Woorabinda' and the Marshalls have managed to keep the property free of the weed, which has spread throughout the district...

A survey of WA grain growers is being conducted to determine the level and extent to which growers undertake Biosecurity best practices on their farms... Management practices that growers indicated as being implemented with a high degree of frequency were such activities as inspecting crops (Fig 4), recording seed sources (Fig 5), keeping records of grain movement (Figs 6 and 7) and, to a lesser degree, general farm hygiene practices such as washing down vehicles and cleaning up around silos... Having biosecurity signage to advise visitors to make contact with the property owners or in keeping records of visitors and having farm plans and designated parking areas for them to use when on their property, rated very poorly as a practice, though the need was acknowledged...

Survey shows grain growers lead biosecurity.. A survey of Australian growers has revealed that crop and livestock producers have a growing awareness of their role in preventing or controlling diseases, pests and weeds... Overall, 97 per cent of growers said they would report a new pest or disease found on their property, but many were unsure who to report it to...

Help needed for herbicide resistance survey.. The survey, which will run across the northern grains region, also represents the first comprehensive investigation into herbicide-resistance levels in Queensland and aims to collect samples from 600 paddocks... "At a farm level growers need to know the resistance levels in their paddocks, so they aren't wasting money and time with ineffective chemicals or weed management strategies, so participating in this survey is one way to get that information for free," Dr Widderick says...

Flexible farming systems will be the focus of the GRDC Technical Research Updates in February... GRDC Southern Panel chair David Shannon says the series of research updates will explore the options available to grain growers in establishing more flexibility within their farming systems... "The grains research updates also play an important role in equipping industry professionals with the knowledge and resources they need to support their grain-grower clients in their preparations and decision-making for the year ahead," Mr Shannon says...

But with Grains Research and Development Corporation (GRDC) supported surveys indicated escalating weed resistance to herbicides including glyphosate, it is likely some weeds will have survived knockdown sprays... A targeted (not random) WA grainbelt survey, conducted by Sally Peltzer of the Department of Agriculture and Food (DAFWA) in 2013, found that more than 40 per cent of 172 annual ryegrass samples tested had some level of resistance to glyphosate... Growers who find weeds surviving herbicide application should send samples to commercial services for a 'Quick Test' in which plants (mainly grasses) are tested for herbicide resistance...

Growers to help detect insecticide resistance.. "Resistance has been detected recently for the first time in a number of important species," Dr Arthur says... University of Melbourne entomologist Dr Paul Umina says information from growers and advisers is needed to develop management strategies, which require understanding of the tendency for resistance to spread and its frequency in southern cropping and pasture areas...

Grain growers in the southern cropping region can now access a new testing service to determine if insecticide resistance exists within populations of redlegged earth mite (RLEM) on their properties... Project leader, Dr Paul Umina, says identification of the gene mutation responsible for pyrethroid resistance has enabled researchers at CSIRO to devise a new cost-effective DNA test which requires fewer mite numbers per test and has greater population screening capacity than previous testing services... To discuss suspected resistance and to facilitate collection of samples for testing, growers in SA, Victoria, NSW and Tasmania are encouraged to contact Paul Umina of the University of Melbourne (phone 03 9349 4723, email pumina@unimelb.edu.au ) in the first instance...
