Antimicrobial Activity of Some Synthetic Compounds on Fungi Associated with Post Harvest Rot of Red Pepper (Capsicum annum)

Rhizopus sp, Mucor sp, Collectotrichum capsici and Geotrichum candidum were isolated but pathogenic test revealed that Collectotrichum capsici and Geotrichum candidum were the most pathogenic of all the isolates. Ni 2+ + Azo has the highest inhibitory effect, closely followed by Ni 2+ + PAN while Copper (II) complex of Thiourea has the lowest inhibitory effect. However, 10 mg/ml concentration proved to be the most effective when radial mycelial growth of the test fungi was measured. The inhibitory effects of each complex on the isolates increases with increase in incubation period. There is the feasibility of using synthetic associated with the symptoms. The three synthetic compounds, Copper (II) complex of Thiourea, Ni 2+ + compounds as preservatives for harvested red
