چکیده
A reduced herbicide rate with hand-weeding (HW) can act as a safer and sustainable approach for weed control. field study was conducted at CSIR-IHBT, Palampur, India during 2018 2019 to analyze the efficacy of herbicides in combination manual weeding on control yield wild marigold (Tagetes minuta L). The experiment laid 12 treatments, consisting two dosages prescribed rates (R) pendimethalin, imazethapyr, carfentrazone-ethyl, along integration reduced-rate treatments HW. population, dry matter, crop biomass had significant effect different weed-control treatments. Imazethapyr HW recorded number (9.64 m−2) matter (13.64 g greater (235.03 q ha−1). All decreased infestation enhanced yield. imazethapyr higher than pendimethalin carfentrazone-ethyl. Weed doses lower recommended doses. Herbicide residues soil all both were below detectable limit (<0.001 μg g−1). Therefore, dose integrated be T. growers more approach.
