Abstract:

An attempt was made to suppress Orobanche in its subterranean stage of development using native arbuscular mycorrhizal fungi (AMF) on tobacco. In this investigation seven AMF spp. were isolated, grouped and mass multiplied according to their morphological differences, from the Orobanche suppressive soil of a tobacco growing area. Further, these seven native AMF isolates and their consortium, a standard AMF consortium, sugarcane native AMF consortium, recommended dosage of an herbicide and uninoculated control- UIC (absence of AMF spp.) were tested against the Orobanche for their bio-control effect under pot experiment on tobacco plant. The maximum inhibition of Orobanche emergence was observed in the treatments received with standard AMF consortium, native AMF consortium, and sugarcane native AMF consortium. While, the UIC recorded highest number of Orobanche infestation (10.25 weed/pot) followed by Fluchloraline @ 2 per cent (7.5 weed/pot). There was an overall improvement in the physiological and biophysical attributes of tobacco upon AMF colonization. The results indicate that the native AMF isolates could be efficiently used to manage Orobanche in tobacco.
