The overuse of insecticides and evolution of resistance in redlegged earth mite (RLEM) is a significant issue for southern and western grain growers. But a new snapshot-style resource is available to help growers make sustainable integrated pest management (IPM) decisions to deal with this pest in canola. It’s called the RLEM best management practice guide, and in this podcast, entomologist Dr Paul Umina talks through the guide in more detail, including factors that influence RLEM numbers in canola and the proactive management strategies.

This podcast has been developed as part of the investment, "Supporting the sustainable use of insecticides and local on-farm implementation of IPM strategies in the GRDC southern region”. The investment aims to provide knowledge and skills to growers so they are equipped with a range of appropriate IPM strategies for their situations. It is being delivered by Birchip Cropping Group, cesar, the South Australian Research and Development Institute (SARDI) which is the research division of Primary Industries and Regions SA, C-Qual Agritelligence, and Queensland Department of Agriculture and Fisheries (QDAF).

There are also best management practice guides, and accompanying podcasts, available for green peach aphid and diamondback moth.
