Interpretive Summary: Our changing climate will likely have serious implications on agriculture production through its effects on food and feed crop yield and quality, forage and livestock production, and pest dynamics including troublesome weed control. With regards to weeds, climatic variables control many plant physiology functions that impact flowering, fruiting, and seed dormancy, therefore, an altered climate can result in a weed species composition shift within agro-ecosystems. Weed species will likely adapt to a changing climate due to their high phenotypic plasticity and vast genetic diversity. This manuscript attempts to compile available information on general principles of weed response to changing climatic conditions including elevated CO2and temperature, and their combined effects under diverse rainfall patterns and drought. Likewise, we have attempted to highlight the effect of changing CO2 levels, rainfall pattern, soil moisture dynamics, and temperature rise on the efficacy of various herbicides under diverse agro-ecosystems.

Technical Abstract: Our changing climate will likely have serious implications on agriculture production through its effects on food and feed crop yield and quality, forage and livestock production, and pest dynamics including troublesome weed control. With regards to weeds, climatic variables control many plant physiology functions that impact flowering, fruiting, and seed dormancy, therefore, an altered climate can result in a weed species composition shift within agro-ecosystems. Weed species will likely adapt to a changing climate due to their high phenotypic plasticity and vast genetic diversity. Higher temperature and CO2 concentration and altered moisture conditions not only affect the growth of weeds, but also impacts the effectiveness of herbicides in controlling weeds. Therefore, weed biology, growth characteristics, and their management are predicted to be affected greatly by changing climatic conditions. This manuscript attempts to compile available information on general principles of weed response to changing climatic conditions including elevated CO2and temperature, and their combined effects under diverse rainfall patterns and drought. Likewise, we have attempted to highlight the effect of changing CO2 levels, rainfall pattern, soil moisture dynamics, and temperature rise on the efficacy of various herbicides under diverse agro-ecosystems.
