Abstract

Interaction of pre-emergent herbicides and crop residues in Western Australian no-tillage systems
The efficacy of pre-emergent herbicides used in Western Australian (WA) no-tillage (NT) systems may be affected by crop residue retained on the soil surface. The main aim of this research was to investigate the interaction of the herbicides prosulfocarb, pyroxasulfone and trifluralin and crop residues in NT systems. Controlled environment and field experiments were conducted to assess the efficacy of these pre-emergent herbicides. Simulated rainfall treatments, crop residue amounts, conditions, types and ages were tested. The efficacy of these herbicides was increased with rainfall amount, particularly for pyroxasulfone, and reduced by the increased ground cover of crop residues.
