aphid management

Catalogue: GRDC Updates
Three varieties were evaluated at each site (Fitzroy , Grout and Gairdner ) with four replicates of all treatments... The pattern was common in all trials assessed to the end of September... Gilgandra Pirimor (300 g/ha) and dimethoate were applied to a population of ~36 aphids/tiller in early October, ~3-4 weeks after all other sites, when all varieties had completed head emergence...

The arrival of the previously undetected Russian Wheat Aphid (RWA) in the southern cropping region has heightened the need for correct identification of aphid species present in this year's crops... The publication now includes information on RWA which was detected in Australia for the first time in May this year and is now established in a number of cropping regions in South Australia and Victoria... Identification of crop aphids is very important when making control decisions and the Back Pocket Guide is designed to assist growers and agronomists in their efforts to correctly identify species observed in crops, this year and beyond...

To support growers and their advisers in identifying aphid species, the Grains Research and Development Corporation (GRDC) has updated its popular Crop Aphids Back Pocket Guide... Identification of crop aphids is very important when making control decisions and the Back Pocket Guide is designed to assist growers and agronomists in their efforts to correctly identify species observed in crops, this year and beyond... Many aphid species also transmit viruses through their sap-sucking mouthparts, leading to the largest impacts on crop yields...

The principal aim of the project was to contribute to the continuing adoption of integrated pest management (IPM) by grain growers in the GRDC's northern region, specifically, the Darling Downs and Central Queensland... The finding suggests that the application of this technique for predator/prey field studies has limited field application... The outcome was achieved through facilitated learning by growers and their advisers via grower group meetings, field day demonstrations, technical literature and presentations by entomologists at technical forums e.g. Grower and Adviser Updates...

Increase the direct exposure of agency researchers to key prioritised industry research questions and needs... A secondary component of this work was to examine the impact of early desiccation timing to both maximise the opportunity to save soil moisture and potentially shorten the re-cropping interval... The clear advantage over previous approaches is to ensure that the actual question or focus of this work is much more driven by industry rather than by the researcher...
