High [CO₂] and Temperature Increase Resistance to Cyhalofop-Butyl in Multiple-Resistant Echinochloa colona.

ABSTRACT: Changes in the environment, specifically rising temperature and increasing atmospheric carbon dioxide concentration [CO₂], can alter the growth and physiology of weedy plants. These changes could alter herbicide efficacy, crop-weed interaction, and weed management. The objectives of this research were to quantify the effects of increased atmospheric [CO₂] and temperature on absorption, translocation and efficacy of cyhalofop-butyl on multiple-resistant (MR) and susceptible (S) Echinochloa colona genotypes. E. colona, or junglerice, is a troublesome weed in rice and in agronomic and horticultural crops worldwide. Cyhalofop-butyl is a grass herbicide that selectively controls Echinochloa spp. in rice.
