Red-legged earthmites (RLEM) cause millions of dollars of damage to crops each year, and due to a cool start to the growing season causing the pests to hatch in April, now is the time for RLEM control... SARDI entomology researcher Kym Perry says growers should not assume that preventative treatments applied at sowing will be an effective solution against pests... RLEM attacks most crops and feeds on all stages of plants, though is particularly damaging to seedlings in autumn...

Native vegetation in grain-cropping landscapes can provide a habitat for beneficial predatory insects, supporting overall pest-control programs... Pastures, especially weedy pastures, provide habitat for pests.. Native vegetation, particularly remnant natural bush, provides a haven and natural food source for beneficial insects, which prey on exotic insects attracted to grain crops and also to many weed species...

Repeated insecticide application keeps increasing the proportion of resistant individuals in a pest population until the majority are resistant to that insecticide... Before deciding to spray crops at tillering, flowering or podding: identify pests and the densities at which they are present in the crop; determine if pest populations are increasing, static or declining; and determine if beneficial insects such as parasitic wasps and ladybird beetles are present... Slug numbers can be estimated by laying a series of carpet squares or large tiles on page 4 the ground with baits underneath...

Inspect plants thoroughly for any unusual damage symptoms.. Use integrated pest management to conserve beneficial insects.. As well as the usual mix of pests such as helicoverpa, mirids and podsucking bugs, this season northern growers also need to be on the lookout for soybean stem fly, bean podborer and etiella in vegetative soybeans says Queensland Department of Agriculture, Fisheries and Forestry (DAFF) researcher Hugh Brier...

The widespread adoption of low tillage farming systems has changed the arthropod pest complex and increased the abundance of some, such as the earth mites and ground dwelling weevils and beetles... We found that crops planted post pasture had in general higher numbers of pests eg earth mites whereas cereals had the lowest number of earth mites present unless weeds were present within the crop... We found that the use of prophylactic sprays does not affect all pests...

The website, http://ipmguidelinesforgrains.com.au , offers detailed information and advice on the management of major insect pests within Australia's major grain crops including specific recommendations for each stage of crop development... Created by the Department of Agriculture, Fisheries and Forestry (DAFF) Entomology team in conjunction with collaborators in all grain growing regions of Australia, the website will equip growers and advisors with the latest industry advice to minimise production loss and implement effective, long-term pest management practices on a whole-of-farm basis... DAFF Senior Extension officer, Entomology, Kate Charleston, said the IPM Guidelines took a problem-solving approach as opposed to being a rigid set of management guidelines, drawing on all available pest management tools to tailor recommendations according to crop type, growth stage and location...

Nutrient management may double as pest control.. Researchers at the University of Western Australia say the findings suggest potential for a new approach to pest detection by monitoring crop nutrient status as a surrogate for identifying actual infestations... Associate Professor Nansen says the research has shown that the potassium status of crops can be characterised using reflectance values at specific wavelengths, so the researchers are now working on a reflectance-based algorithm that can predict a crop's suitability to host insects...

Slugs are present in all major grain growing regions in Australia and can pose a threat to growers in the higher rainfall regions of Western Australia... In terms of economic loss, they are the sixth most damaging invertebrate pest for the Australian grains industry, costing on average $25.9 million in lost production across a variety of crops... An integrated pest management (IPM) approach is required to effectively control slugs, which can be underestimated as pests because they are not generally visible during daylight hours The Grains Research and Development Corporation (GRDC) has released a fact sheet Slug identification and management that discusses how to effectively use a combination of measures to control them...

Mice on the move in CQ - plan ahead and protect summer crops.. Thankfully mouse populations have not reached levels which pose a significant threat to yield during the current harvest, but a number of growers from the Central Highlands, Arcadia, and Callide-Dawson Valleys are reporting rising numbers around their farms... Remember that mice are vermin and can carry disease; gloves should be worn when handling mice and appropriate occupational health and safety procedures, including protective clothing, should be adhered to when handling poisons...

Mice threaten Darling Downs crop yields.. "A number of Darling Downs grain growers are reporting crop damage and we have already baited once on our farm," Mr Taylor said... Some tell-tale signs that mice are on the move are burrows and holes around the farm; mouse droppings on the soil and plants; seeds being dug up and plants being gnawed; and more birds of prey than normal...
