Field evaluation of different IPM modules against mustard aphid, Lipaphis erysimi (Kalt.) in Bundelkhand region

Four different IPM modules were designed and tested for the management of mustard aphid in mustard crop including farmer practices. It was observed that all four IPM modules significantly reduced mustard aphid incidence on mustard crop and enhanced the yield over farmers’ practices (FP). The Module 4 [Taramira (Trap crop) + Installation of yellow sticky trap @ 25/ha + Two spray with Acetamiprid 25 SP @ 25 g a.i./ha] was found most effective treatment with minimum number of aphids and it was significantly superior over rest of the treatments. It is followed with the Module 3 [Taramira (Trap crop) + First spray of Beuauveria bassiana @ 1 kg/ha + Second spray Nimbicidine 0.03 EC @ 2.5 liter/ha], Module 1 Installation of yellow sticky traps @ 25/ha + First spray of NSKE 5% + Second spray of Lantana leaf extract 1.5%) and Module 2 (Manual removal of infested twigs + First spray of Verticillium lecanii @ 2.5 kg/ha + Second spray Kunap Jal) were effectively found to reduce aphid population. The highest yield (15.53 q/ha) recorded in Module 4. All the IPM modules were significantly superior over the farmer practices.
