The adaptive value of flowering time in wild radish (Raphanus raphanistrum)

This paper demonstrates that an early flowering time adaptation does not come at a growth cost when in competition with wheat. Flowering time however did result in an increasing number of flowers being located below the harvest cutting height. As the early flowering wild radish does not come at a competitive cost, it needs to be managed through diversity in both management tactic and timing.

Identification of the first glyphosate-resistant capeweed (Arctotheca calendula) population

capeweed

This is the first confirmation of glyphosate resistance evolution in a capeweed population globally. With capeweed resistance already confirmed to photosystem-I inhibiting herbicides (paraquat and diquat), this study emphasizes the importance of using integrated measures that do not depend only on the use of non-selective herbicides for controlling herbicide resistance-prone capeweed populations.
