The Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), is a Lepidoptera: Noctuidae was first detected in the Indian subcontinent, in the districts of Bangalore Rural and Chikkaballapur (Ganiger et al. 2018) and during the first week of July 2018, South Karnataka (ICAR-NBAIR pest alert, 2018), and is currently moving to Tamil Nadu. FAW is widely distributed in India, causing significant damage to maize. Synthetic pesticides have been the primary technique for controlling fall armyworms. As a result, in the Americas, the fall armyworm is resistant to at least 29 insecticidal active components from six different mode-of-action groups. Six new synthetic pesticides from various chemical groups were evaluated in open fields as solo mixtures and tank mixtures for their effectiveness against maize FAW. Spinetoram + Novaluron (76.67%), Spinetoram + Emamectin (70%) and Chlorantraniliprole + Novaluron (64.29%) outperformed all other tank mixture combinations in terms of effectiveness and knockdown impact (24 hours after application) over control. When administered alone, Spinetoram has a better efficacy and a longer duration of efficacy than other solo spray. When CTPRL and spinetoram were compared, spinetoram had a prolonged effectiveness than CTPRL. When compared to untreated plots, spinetoram + novaluron demonstrated good plant height growth (181 cm). When compared to whole plant treatment, leaf whorl application had high effectiveness and lowered pesticide requirements and consumption.
