<div>Background: Capsicum (Sweet pepper or Bell pepper), Capsicum annuum L. also popularly called as Simla mirch in India is one of the leading vegetables grown in open conditions as well as under protected conditions. It is attacked by various insect and mite pests from seedling to fruiting stage. The damage caused by Spodoptera litura (Fabricius) during flowering and fruit formation is the most concern and farmers everywhere feel the need to protect such high value crops from any type of damage caused by insect pests.</div>

<div> 
Methods: The trial was conducted under poly house condition during kharif 2019 at horticulture garden, College of Agriculture, Rajendranagar, Hyderabad. The experiment was laid out in randomized block design (RBD) with eight treatments replicated thrice in a 7.5 m &times; 1 m plot size with a spacing of 45 cm &times; 40 cm. The capsicum hybrid WS 234 was raised as per the recommended package of practices except plant protection measures.&nbsp; The observations on pest incidence were recorded one day before treatment imposition as pre-treatment count. Post treatment counts were recorded at one, three, five and seven days after each chemigation/spray.</div>

<div> 
Result: The present study indicated that treatment of cyantraniliprole 10.26% OD @ 90 g a.i. ha-1 applied through drip chemigation was effective by recording minimum larval population with lowest fruit damage over all the other treatments. The next best treatment was cyantraniliprole 10.26% OD @ 60 g a.i. ha-1 applied as foliar spray. The order of moderate effective treatments were drip applications of cyantraniliprole 10.26% OD @ 60 g a.i. ha-1 &gt; cyantraniliprole + thiamethoxam 19.8+19.8 w/w @ 64 g a.i. ha-1 &gt; cyantraniliprole + thiamethoxam 19.8+19.8 w/w @ 32 g a.i. ha-1 &gt; imidacloprid 70 WG @ 50 g a.i. ha-1 &gt; imidacloprid 70 WG @ 25 g a.i. ha-1.</div>

Background: Fall army worm is an invasive insect pest in India during year 2018 which caused severe damage to the crop and economic loss to the farmers. So, the main objective of the study is to evaluate the efficacy and effectiveness of seed treatment, biological and insecticidal applications for the management of fall army worm in maize.&nbsp; 
 
Methods: The study was conducted Kharif, 2018 and 2019 at Regional Agricultural Research Station, Chintapalle, Visakhapatnam during. It was evaluated with eleven treatments, after seed treatment with Cyantraniliprole 19.8% + Thiamethoxam 19.8 FS 5 ml per kg seed in 03 windows of application at 20, 35 and 50 DAS with battery operated sprayer. Data was collected on number of larva per plant (20 DAS), per cent plant infestation and % cob infestation, yield (q/ha) and cost benefit ratio. 
 
Result: Among three windows of applications, third window application with different insecticides was found most significant, followed by second window application (poison bait with Thiodicarb 75WP) in comparison to control (20.96). In 3rd window treatments application, spinetoram 11.7SC @ 0.5ml (T3 with 0.74 and T8 with 1.14 %) and spinosad 45SC @ 0.3 ml (T4 with 1.35 and T9 with 1.39 %), were found most significant, followed by&nbsp; &nbsp;Chlorantraniliprole 18.5SC (T2 with 1.76 and T7 with 1.25 %) in the management of fall army worm. Least Cob damage per cent (T3 with 7.23 and T8 with 8.00 %) and maximum yield (T3 with 72.55 and T8 with 73.00 q/ha) was recorded in Spinetoram 11.7 SC. Thus Spinetoram 11.7SC followed by Spinosad 45SC and Chlorantraniliprole 18.5SC found effective against S. frugiperda in Maize.
