Title: Management of root-knot nematode infecting brinjal by biopesticides, chemicals, organic amendments and bio-control agent
Abstract: The potential of bio-pesticides, chemical pesticides, organic amendments and bio-control agent was studied in controlling the root-knot nematode Meloidogyne incognita on brinjal “cv” Dilnasheen in two greenhouse experiments. In first experiment bio-pesticides (Abamectin and Azadirachtin) and a chemical pesticide Lorsban were tested alone and in combination with a bio-control agent Pasteuria penetrans for the management of root-knot disease. The best control (61 %) in root galling was recorded in pots treated with Azadirachtin + P. penetrans followed by Abamectin + P. penetrans (52 %), Abamectin and P. penetrans (48 %), Lorsban + P. penetrans (42 %), Azadirachtin (36 %) and Lorsban (21%) compared with unamended control. All the treatments showed significant reduction in egg-masses compared with untreated control; however, maximum decrease (66 %) in egg-masses was recorded in Azadirachtin + P. penetrans treatment while lowest reduction (45 %) was observed where Lorsban was applied. In another experiment bio-pesticides (Abamectin and Emamectin) and organic amendments (saw dust and kanair leaves) and a chemical (Furadan) were evaluated in controlling the root-knot disease. Abamectin proved to be the best in reducing root galling (62 %) and egg-masses (79 %) followed by Furadan while other treatments showed intermediary effects compared to untreated inoculated control
