Abstract: An investigation was carried out to isolate native AM fungal (AMF) isolates from the Striga suppressive soils of sugarcane growing areas of northern Karnataka. Further, sixteen native AMF isolates were screened for their ability to suppress Striga as well as plant growth promotional abilities in sugarcane under pot culture studies. The pots were filled with Striga infested soil prior to the planting of sugarcane sets of equal bud size. AMF inoculum @ 150 g pot 1 was mixed thoroughly with the top10 to 15 cm of the soil and pots were treated with Hoagland’s nutrient solution once a week. The data on the emergence of Striga, Striga biomass, plant height, chlorophyll content and soil microbiological activities were recorded. The striga emergence was significantly inhibited in the treatment received standard AMF consortium, followed by AMF native consortium, UASDAMF -2, UASDAMF-5, UASDAMF-9 and UASDAMF-12. While, the UIC recorded highest number of striga infestation. Furthermore, the plant height, chlorophyll content, soil enzyme activities and spore load/ 50gm of soil were recorded highest with native AMF consortium over uninoculated control. Thus, our preliminary findings are indicative of the effectiveness of AMF in protecting Sugarcane against Striga infestation and hence can be a promising strategy to develop a biological tool for Striga control.
