Stay one step ahead of insect pests this cropping season.. "PestFacts subscribers provide pest reports and field observations on the appearance and distribution of invertebrate pests across south-eastern Australia," Mr Shannon said... PestFacts South-Eastern subscribers also benefit from special access to cesar's extensive insect image gallery which can be used by growers, agronomists, farm advisers and researchers to enable more accurate identification of pest and beneficial insects...

The integrated management of insect pests in grain crops on the Eyre Peninsula will be the focus of a workshop for advisers and growers at Cummins on September 11... The Grains Research and Development Corporation ( GRDC) workshop is locally supported by Dow AgroSciences and Syngenta and addresses the needs of advisers and growers who seek an improved understanding of insects and their management to assist with implementation of more sustainable insect management practices... Workshop topics include implementing an integrated approach to insect management and decision making; monitoring, thresholds and management strategies for regionally important crops and insects; and integrated pest management tools including conserving beneficial insects and more selective insecticide options...

A near-perfect start with good summer and autumn rain coupled with mild temperatures saw crops jump out of the ground... Insect pests including green peach aphid (GPA) and the resulting beet western yellows virus (BWYV or synonym, turnip yellows virus) and diamondback moth (DBM) both proved headaches for growers at different stages of the growing season... Mr Baker says the colonisation of DBM in canola crops this year looks to be at a lower level for much the same reason as the risk of GPA and BWYV is this year - a much drier summer and early autumn than last year and less of a green bridge on which to survive...

Many decisions to manage crop establishment pests should be made well before sowing when there are far more control options available... Extremely high levels of resistance to several synthetic pyrethroids (> 200,000 fold in the case of bifenthrin) were detected using laboratory bioassays, and this has translated to significant yield losses in the field... Further properties with insecticide resistance have been detected since 2010, although at this stage, resistance has not been detected outside of WA. Experts predict resistance in RLEM will spread to other states, including to Victoria...

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...

Entomologist Dr Melina Miles from the Queensland Department of Agriculture, Fisheries and Forestry (DAFF) says the calculator assists growers to assess the cost-benefits for controlling Helicoverpa moth and sorghum midge... "Calculating the economics of insect control measures is critical to making decisions about if and when pest populations require treatment," Dr Miles says... "The calculator provides an easy way to run a range of likely pest pressure and cost of control scenarios," Dr Miles says...

Diamondback moth alert for canola crops.. While growers have been focused on the threat posed by green peach aphids, diamondback moth (DBM) also has the potential to cause significant losses in canola this season... Regional movement of DBM and colonisation of canola in southern Australia (University of Adelaide): PhD project to improve the understanding of movement of resistance types within a population to manage resistance, and learn more about timing and sources of colonisation to better predict which seasons will present a risk of DBM damage...

Knockdown with Dichlorvos alone, applied to grain at in-loading (Table 1)... Dilute liquid concentrates in water at the specified rate per litre, then spray 1 litre of the mixture per tonne of grain while auguring the grain or spray 1 litre per 20 square metres of grain surface to control moths... The spray equipment must be calibrated to spray 1 litre of solution per tonne of grain...
