Barley grass is becoming an increasingly problematic weed in Western Australia. A GRDC funded project sought to increase adoption of integrated weed management tactics for barley grass, by working with grower groups to develop regionally appropriate rotations for optimal control.

A survey indicated that in growers in the northern wheatbelt felt that barley grass was most likely to be a major problem in pasture, and a common response is use of Group A herbicide to remove grass in pasture. However, given how easy it is to develop Group A resistance, the group wanted to investigate other chemical and non-chemical options in pasture, as well as the impact of late seeding and pre-emergent herbicide for barley grass control in crop.

This three year trial aimed to investigate slashing and spray topping in pasture in 2019, and then time of sowing and pre-emergent herbicides in wheat in 2020 and canola in 2021.

To investigate the N rate and time of application response of canola varieties to yield and oil content of Triazine tolerant (TT) and Roundup Ready (RR) hybrids in comparison with open-pollinated (OP) types to:

1. Provide growers in lower rainfall environments with guidelines on times of application to maximise grain and oil yields.
2. Determine if the management of hybrid canola nutrition is different to that of open pollinated varieties due to different responses to N rates and timing.

To investigate the nitrogen rate and time of application response of canola varieties to yield and oil content of TT and RR hybrids in comparison with open-pollinated types to

• provide growers in lower rainfall environments with guidelines on optimal nitrogen rates and times of application to maximise grain and oil yields, and
• determine if the management of hybrid canola nutrition is different to that of open pollinated varieties due to different responses to N rates and timing.
