| Abstract: | Aims] Fluorochloridone is a new herbicide to broadleaf weeds,the feasibility of fluorochloridone in cotton and potato fields was evaluated.Methods] Weed control efficacy and potato,cotton safety of fluorochloridone 25% SC were evaluated in greenhouse.Results] The result showed that fluorochloridone had better effect on Amaranthus retroflexus,Abutilon theophrasti,Acalypha australis with the eD50 of 127.807 4,111.061 6 and 104.673 1 g a.i./ha,eD90 of 500.177 5,335.150 4 and 262.9190 g a.i./ha.it had good safety to potato and cotton,and the eD10 is 1786.2082 and 1856.1773 g a.i./ha.Conclusions] It was illustrated that fluorochloridone could be applied on controlling the broadleaf weeds in potato and cotton fields. |
