Why GRDC invested in the Herbicide Innovation Partnership in 2015
Issue 169, March-April 2024 - 24 Apr 2024Australian grain growers face a significant challenge, with weeds causing an estimated annual loss of $3.3 billion, approximately $146 per hectare. This issue, the most costly for global crop production, is exacerbated by a dramatic decline in new herbicide development and increasing herbicide resistance.

Liming and spading trial shows value of strategic tillage
Issue 169, March-April 2024 - 22 Apr 2024Given the slow rate at which surface-applied lime moves into untilled soil, strategic tillage has been considered the best way to correct subsurface acidity within a reasonable time frame. Now, the results of a four-year study indicate spading could improve soil pH and increase lentil yields across a range of liming rates and spading speeds.

Balancing the bitter-sweetness of lupins to increase their consumption
Issue 169, March-April 2024 - 08 Apr 2024Chunsheng Xiao is applying innovative science to understand the molecular basis of the bitter alkaloids in narrow leaf lupin in pursuit of developing ‘bittersweet’ lupins. The aim is to retain the bitter alkaloids in the plant’s vegetative parts as a means of pest defence whilst disrupting the translocation of the alkaloids to the seed.
