Keywords: clodinafop-propargyl + sodium-acifluorfen; phytotoxicity; selectivity; soil enzymes; weed dry weight; yield Abstract Weeds result in a significant yield loss in mungbean (Vigna radiata [L.] R. Wilczek). However, post-emergence (POST) herbicides are limited in mungbean for broad-spectrum weed control. Therefore, we evaluated the efficacies of different herbicides in mungbean to find a suitable broad-spectrum POST herbicide. Nine herbicides, weed-free check, and unweeded control treatments were tested in a randomised block design with three replications for two consecutive years. Among the tested herbicides, clodinafop-propargyl + sodium-acifluorfen 122.5 g a.i. ha.sup.-1 applied at 15days after sowing (DAS) reduced the broad-leaved weed dry weight at 35 DAS and harvest by 55.8% and by 58.6% (p Article Note: Chaitanya P.
