Abstract
The field experiment was conducted to study the comparative performance of various insecticides and biopesticides against Helicoverpa armigera and Spodoptera frugiperda. Chlorantraniliprole 18.5SC @ 0.4ml/l showed the most effective control on H. armigera and S. frugiperda, with pooled mean larval population of 0.42 and 1.16 larvae/plant followed by emamectin benzoate 5 SG @ 0.4g/l (0.52 and 1.24 larvae/plant), spinaosad 45 SC @0.3 ml/l (0.62 and 1.32 larvae/plant), indoxacarb 14.5 SC@ 1ml/l (0.73 and 1.42 larvae/plant) and novaluron 10 EC @0.1ml/l (0.83 and 1.52 larvae/plant). The least effective treatment was agniastra @1000ml / 50 l (1.19 and 1.81 larvae/plant) after control (2.08 and 2.82 larvae/plant) followed by nimbicidine 0.03 EC @5ml/l (1.03 and 1.75 larvae/plant) and Bacillus thuringenesis @ 2g/l (0.92 and 1.62 larvae/plant). The results concluded that chlorantraniliprole, emamectin benzoate, indoxacarb and novaluron consistently demonstrated a significant reduction in larval population and the longest residual. Whereas, Bt and nimbicidine provided moderate control and the shortest residual capacity, which is favorable to the environment.
The efficacy of selected chemicals, botanicals and biopesticides against fall armyworm (FAW; Spodoptera frugiperda) on fodder maize var. African Tall was conducted from 2019 to 2021 at five locations in India. The pooled data revealed that at 3 days after spraying, the FAW population was lowest (16.53% infestation of p...

Fall armyworm, Spodoptera frugiperda, is a major maize pest requiring effective and environmentally sustainable management strategies. This study evaluated the efficacy of Beauveria bassiana, Metarhizium anisopliae, pheromone traps, and their integration under field conditions in Iraq. Significant differences (P ≤ 0.05...
The present study was conducted to evaluate the bioefficacy of botanical and chemical insecticides against brown planthopper, Nilaparvata lugens (Stal), in paddy. The experiment was conducted using the following treatments Azadirachtin 5 % (60, 70 and 80 mL), BrahamAstra (7.5, 10.0 and 12.5 L), homemade neem (2.0, 3.0...

The fall armyworm, Spodoptera frugiperda (J. E. Smith), is an invasive maize pest for which reliable baseline susceptibility data are required to support insecticide selection and resistance monitoring. This laboratory study compared the toxicity of five commonly used insecticides—emamectin benzoate 5 SG, chlorantranil...

The green peach aphid is one of the most destructive sucking insect pests infesting spinach. Field experiments were conducted at the Vegetable Research Farm, Rahuri, during the Rabi seasons of2020 and 2021 to assess the comparative evaluation of selected insecticides and biopesticides against this pest. Among the tre...

A field experiment was undertaken to evaluate the efficacy of biopesticides against major insect pests of broccoli, Myzus persicae and Pieris canidia. Significant differences were observed among the treatments against both insect pests. Against Myzus persicae, Imidacloprid 17.8 SL @ 0.3 ml/ l recorded the highest overa...
