Edgar Varón, Márcio Dionízio Moreira, Jenny Paola Corredor-Prado

Abstract

2 =0.44 and a p < 0.0001 for the upper surface. Efficacy of control after three days of insecticide application was: thiamethoxam + lambdacyhalothrin (0.00%), spinetoram, (0.00%), malathion (20.35%), thiamethoxam (38.62%), dimethoate (86.94%) and imidacloprid (87.33%). After seven days of insecticide application the efficacy was thiamethoxam + lambdacyhalothrin (0.00%), spinetoram (21.46%), malathion (38.77), thiamethoxam (50.84%), dimethoate (86.14%) and imidacloprid (90.37%). results obtained after 16 days lacked many sampling unit leaves, which made their analysis meaningless, after that period of time.
