Bioefficacy of different herbicides in fenugreek

Pre-emergence or pre-plant incorporation of imazethapyr at 80 g/ha either alone or in combination with one hoeing at 45 DAS provided 80–95% control of C. album, C. murale, C. didymus and R. dentatus without any adverse effect on fenugreek. Post emergence application of this herbicide at 70 g/ha or its ready mixture with imazamox (Odessey) although provided 58–78% control of weeds but caused suppression in crop growth with yield penalty of 28–33% as compared to weed free check. Pre, PPI and post-emergence application treatments of imazethapyr and imazethapyr + imazamox (RM) caused suppression in cotton and okra crops. Crops blackgram, bottle gourd and bottle gourd were safe to grow after use of imazethapyr and its ready mix combination in fenugreek.
