Biological management of Orobanche with Fusarium oxysporum - a new record from India.

摘要

In a survey conducted in Churu and Jhunjhunu, Rajasthan and Mahendragarh, Haryana, India, rapeseed mustard crop was found to be heavily infested with Orobanche ramosa (10-90% infection). Critical examination of the heavily infested rapeseed mustard fields with Orobanche weed, mustard plants were in healthy condition in few patches whereas Orobanche plants in those patches showed wilting or diseased symptoms. The pathogen was identified as Fusarium oxysporum. A review of literature revealed that F. oxysporum constitutes a new host record on Orobanche ramosa from India, as well as a new potential tool as a biological control agent for the management of this weed.
