Residual Control of Paradoxa Grass in Barley locations
Aims

To evaluate herbicide options for residual control of Phalaris paradoxa in cereals

Key messages

Paradoxa grass (Phalaris paradoxa) is an important weed of winter crops, particularly in seasons when wet conditions occur in late autumn and early winter. Improved understanding of the potential for residual paradoxa grass management is needed due to increasing levels of Group 1 (A) and 2 (B) post-emergent herbicide resistance.

This project was developed to evaluate a range of residual herbicides for paradoxa grass (phalaris) control in wheat. However, a mix-up occurred at sowing with the paddock planted to barley rather than the planned wheat crop.

Although Sakura and Luximax are not registered for use in barley, the trial was continued to generate efficacy data on paradoxa grass but also evaluate crop safety in barley. All of the herbicides applied have annual ryegrass control registrations with three of them having paradoxa grass control claims when applied at planting in wheat: Sakura, TriflurX and Mateno Complete. Overwatch has a paradoxa grass suppression claim when applied at planting.
