10.13 Conclusions

The effects of climate change on weed-plant
interactions are likely to vary by region and crop
type. Understanding of the underlying physiolog-
ical mechanism responses to such factors is
needed in order to address these effects. Because
the interactions between crops and weeds are
“balanced” by various environmental factors,
local changes in these factors may tip the scale
towards either crop or weed. Furthermore, as the
geographic distribution of weed species changes,
so will the community composition, posing both
challenges and opportunities for invasion control.
If the invasion of new weed species can be
detected, efforts can be made in advance to pre-
vent and control their establishment.
