Summary
The Russian wheat aphid (Diuraphis noxia, RWA) was first detected in the Mid North of South Australia in late May of 2016. RWA is an economically important pest of wheat, barley and other cereal grains. Unlike other cereal aphids that damage plants by removing nutrients, RWA also injects salivary toxins during feeding that cause rapid, systemic phytotoxic effects on plants, resulting in acute plant symptoms and potentially significant yield losses. It is important to conduct research in a timely manner in order to advise growers when and how best to control this species effectively for the 2017-cropping season. This project will provide growers and advisors with knowledge on the effectiveness and protection duration of registered seed dressings for the management of RWA, as well as the comparative effectiveness of pirimicarb and chlorpyrifos against RWA, including the effects of temperature. The results will be conveyed to GRDC in the form of final trial reports, presented at GRDC updates and disseminated through other mediums such as PestFacts.
