Evaluation of Insecticide Resistance Management Components against Sucking Pests in Bt. Cotton

On farm trial on evaluation of insecticide resistance management module (IRM) was conducted at five different locations at farmers’ fields with close supervision of JNKVV, Krishi Vigyan Kendra, Harda, (MP) during kharif, 2008–09. The present findings revealed that population of sucking pest viz., aphid (9.45/three leaves), jassid (1.89/three leaves) and whitefly (5.71/three leaves) were minimum in IRM plots than farmers’ practice. Maximum seed cotton yield (26.10 q/ha) was recorded in demonstration plot in comparison to farmers’ practice (21.50 q/ha). Higher B: C ratio and net return was also obtained in IRM plot. IRM module proved significantly effective in controlling sucking pests infestation and increased seed cotton yield.
