A field trial was conducted to evaluate the efficacy of novel chemistry insecticides in managing the sucking pests of cotton during the year 2018 at Regional Agricultural Research station, Nandyal. Results revealed that new molecule Flonicmide @ 0.3 g/lit of water had registered lowest mean leafhopper population of 2.56 and 2.59/3 leaves after first and second sprays respectively followed by Difenthiuran @ 1.25g, Sulfoxaflor @ 0.7ml and Spinetoram @ 0.6ml which registered 2.93, 3.12, and 3.90 leafhopper population per three leaves respectively after first spray. Same trend was noticed after second spray also. Highest yield of 2348 kg/ha was recorded in treatment Flonicmide @ 0.3 g/lit.
