Article Abstract
Bixlozone, a proherbicide that requires in planta activation to its phytotoxic form, 5-ketobixlozone, is used to selectively control annual ryegrass () in Australian cereal and canola crops. Bixlozone resistance has been detected in southern Australian annual ryegrass populations, and this can be increased with recurrent selection. The metabolic fate of bixlozone in young weed and crop seedlings was investigated by liquid chromatography-mass spectrometry to determine if differential metabolism can explain differences in bixlozone response. The observed tolerance of canola and wild radish () was due to the reduced activation of bixlozone to 5-ketobixlozone. In contrast, a resistant annual ryegrass population and tolerant wheat and barley showed preferential conversion of bixlozone to hydroxylated derivatives, whereas susceptible annual ryegrass populations produced more 5-ketobixlozone. Direct application of 5-ketobixlozone to seedlings resulted in an unexpected conversion to hydroxylated metabolites, potentially implicating plant reductases in 5-ketobixlozone metabolism.

Legumes are a potentially important N source in pasture systems, but quantifying the transfer of biologically fixed N from the legume to the grass component is difficult. A greenhouse H-pot system was developed to directly estimate belowground N transfer from biological N fixation (BNF) using N. The system was tested with 'Prine' annual ryegrass (Lolium multiflorum L.

Microorganisms associated with belowground carbon availability play a critical role in the functions and sustainability of grazing grassland ecosystems. However, research on microbial responses to varying grazing intensities at different soil depths remains limited. This study examined rhizosphere bacterial communities under varying defoliation intensities in a 24-week pot experiment involving repeated defoliation of annual ryegrass (Lolium rigidum).

Peanut ( L.) continuous cropping reduces yield and quality, but the effects of specific rotation methods on yield and endophytic bacterial colonization remain unclear. Based on five years of continuous cropping trial data, three different cropping systems (WF, annual summer peanut and winter fallow; GM, annual summer peanut and winter ryegrass; CR, summer peanut rotated with summer maize and winter wheat) were employed in this study to systematically analyze and evaluate the effectiveness of crop rotation in mitigating peanut continuous cropping obstacles and its underlying mechanisms.
