Comparison of crop and weed height, for potential differentiation of weed patches at harvest

The aim of this study was to determine whether weed patches could be differentiated from the crop plants, based on height differences.

Are herbicide mixtures unaffected by resistance? A case study with Lolium rigidum

This study provides examples showing that target-site resistance to POST herbicides and non-target-site resistance to PRE herbicides can be overcome by offering direct evidence across many L. rigidum populations screened. Evolved resistance to binary herbicide mixtures in individual plants may require the accumulation of multiple traits (at least two genetic traits) conferring resistance to each herbicide component applied at the maximum recommended dosage.

Diversity of α-tubulin transcripts in Lolium rigidum

This research reveals the complexity of the α-tubulin gene family in individuals/populations of the cross-pollinated weedy species L. rigidum, and highlights the need for better understanding of the molecular architecture of tubulin gene families for detecting resistance point mutations. Although TUA4 is a commonly expressed α-tubulin isoform containing most frequently reported resistance mutations, other mutant tubulin isoforms may also have a role in conferring dinitroaniline resistance.
