Abstract
Corn (Zea mays) is one important food ingredients in Indonesia because it is the second source of carbohydrates after rice, as industrial raw material and animal feed, so it is important to maintain the quality of the seeds especially against the presence of pathogenic fungi. This study aims to determine the effect of type disinfectant on the infection of seed borne pathogenic fungi on corn seed. Detection of pathogenic fungi on corn seeds was carried out using the standard method of seed health testing of the International Seed Testing Association (ISTA, 1996) is blotter test method. Surface sterilization was carried out using 3 disinfectants are sodium hypochlorite (NaOCl) 1% (10 minutes), alcohol 70% (10 minutes), and mixture of NaOCl 1% with alcohol 70% (10 minutes). The research method is to compare the effectiveness of disinfectants, and each sample uses ±200 seeds. Observations were made on the homogeneity of the number of infected seeds and the index of fungal diversity. The results showed that all disinfectant suppressed the infection of seed borne pathogenic fungi on corn seeds are NaOCl 1% (84%), alcohol 70% (64%), mixture NaOCl 1% with alcohol 70% (61%), the fungal diversity index are NaOCl 1% (1.15 is medium), alcohol 70% (0.62 is low), mixture NaOCl 1% with alcohol 70% (0.55 is low).
