Use of Neem (Azadirachta indica) seed powder to treat groundnut seed-borne pathogenic fungi

Dauda Hassan, Murtala Nyako Galti and Bulama Ali

Plant seeds powder and extracts are being used to control the diseases since last several years. Extracts of the various plant parts like leaf, stem, root, fruit and seeds are found to be effective against seed-borne pathogenic fungi. The present study involved groundnut seed health test for seed-borne fungi and the evolution of Azadirachta indica seed powder as seed treatment bio-fungicides. These materials was used at the concentration of 0.1%, 0.5%, 1.0%, 2.0%, 5.0% 10.0% and control, while Apron plus was used at the recommended dose and two times the recommended dose the later being included for comparative purposes. The following fungi Aspergillus niger, Aspergillus flavus, and Rhizopus species were isolated from both untreated seeds. Treatment with Apron plus was found to be more effective than Azadirachta indica seed treatment which was found to significantly reduce the prevalence of Most of the isolated fungi the reduction being dosage dependent, Aspergillus niger is found to show resistant to neem (Azadirachta indica) seed powder. The application of plant material to control pathogenic fungi is receiving attention among scientist worldwide. The potential of Azadirachta indica seed powder to treat pathogenic seed borne fungi is promising. This plant seed powder can possibly be exploited in the management of seed-borne pathogenic fungi to prevent biodeterioration of seeds in an eco-friendly way.
