Alternative herbicides for management of Group A herbicide-resistant barley grass in field pea

Alternative herbicides for management of Group A herbicide-resistant barley grass in field pea

Weed management practices used in cropping systems of South Australia have increased seed dormancy in barley grass populations. This evolving characteristic has enabled barley grass to escape typical pre-sowing control and establish after crops have been planted. Consequently, local growers have relied heavily on post-emergence herbicides, particularly those from mode of action Group A, leading to resistant populations.

This factsheet outlines some alternative herbicide options.
