| Abstract | ||||
| Weeds are amongst the major serious agricultural pests of faba bean (Vicia faba L.) production in Egypt and should be controlled. Clethodim is the only post-emergence herbicide registered for grass weed control in faba beans in Egypt. Two field separate experiments were conducted at Assiut University farm in two different locations in 2021-2022. The first field experiment aimed to evaluate the efficacy of some lipid–inhibitor herbicides (clethodim 24%, clethodim 12%, clethodim + haloxyfop 22.6%, diclofop-methyl 36%, fenoxaprop-p-ethyl 7.5%, quizalofop-p-ethyl 5%, and thiobencarb 50%) and hand hoeing treatments for controlling the grass weed, Phalaris minor Retz in faba bean. The second field experiment aimed to evaluate the effects of bentazon 48% herbicide on broad-leaf weeds in faba bean. Phalaris minor was the only grass weed presented in the first experimental field, while Beta vulgaris L., Cichorium pumilum Jacq. and Ammi majus L. were the dominant broadleaf weeds in the second experimental field. In the first experiment, all selected lipid–inhibitor herbicides except fenoxaprop provided 89.49–98.58% in controlling P. minor compared with the weedy control at 62 days after crop sowing. Among all lipid–inhibitors, clethodim 24%, thiobencarb 50%, diclofop-methyl 36%, and clethodim + haloxyfop 22.6% performed the highest increment (82.81–86.57%) in faba bean yield versus control. In the second experiment, bentazon 48% provided excellent efficiency against broadleaf weeds with weed reduction of up to 95% and increased faba bean yield by 69.54% compared with the control at 68 days after crop sowing. In the current scenario, the grass herbicides (clethodim 24%, thiobencarb 50%, diclofop-methyl 36%, and clethodim + haloxyfop 22.6%) and a broadleaf herbicide (bentazon 48%) can be used as a promising chemical herbicide option for the control of weeds in faba bean cv.
