Aims:
This paper reports on the priority diseases identified in the 2020 crop surveys and highlights implications for grains producers in 2021.
Aims:
Barley grass is now one of the top 10 weeds of Australian cropping in terms of area infested, crop yield loss and revenue loss (Llewellyn et al. 2016). Barley grass has several biological traits that make it difficult for growers to manage it in the low rainfall zone, so it is not surprising that it is becoming more prevalent in field crops in S… read more
Aims:
Brome grass is the costliest weed to grain production in the Mallee region despite herbicide resistance being relatively low. This paper brings together research trials from 2015 and 2016 addressing the potential for greater efficacy of pre-emergence herbicides on brome and the potential for better crop competition on non-wetting sands. For grow… read more
