Why do the trial? 
Barley grass possesses several biological traits that make it difficult for growers to manage in the low rainfall zone, so it is not surprising that it is becoming more prevalent in field crops in SA. A survey by Llewellyn et al. (2015) showed that barley grass has now made its way into the top 1 0 weeds of Australian cropping in terms of the area infested, crop yield loss, and revenue loss. In this survey, barley grass was ranked as the 7th most costly weed to control by the growers in SA and VIC Mallee and Mid-North, Lower Yorke and Eyre Peninsula. In a previous random survey in SA in 2012, Shergill et al. (2015) identified resistance to quizalofop in 15% of barley grass populations from Upper North and Eyre Peninsula. Additional herbicide-resistant populations have been identified since the previous survey. Growers in these regions have observed many control failures and have been collaborating with this GRDC-funded project to confirm the resistance status of their barley grass populations. 

The purpose of this laboratory-based incubation experiment was to determine if an upper limit to Organic Carbon accumulation in soil was approached with increasing C input in basalt- and granite-derived soils.

This research aims to trial and demonstrate different management practices which could be used by growers to ameliorate saline soil patches:

1) Amending soil with sand, straw or gypsum - application of amendments to the soil surface can improve crop emergence by reducing evaporation leading to more soil moisture, or by reducing the moisture required to germinate a seed by increasing the sand content of the soil surface. Gypsum was also included to increase the amount of calcium relative to the level of sodium (salt) and address sodicity in the longer-term.  

2) Selecting crop types/varieties – to investigate the differences in crop performance on saline soils between crop types and varieties with improved salt tolerance.

The aim of these projects was to monitor and detect strong resistance to phosphine in the five major stored grain beetle pests, as well as record all details that might have led to any development of resistance, in order to control these outbreaks, develop a phosphine resistance management strategy and,consequently, prolong the life of this fumigant.
