Abstract

A large number of microorganisms' parasite on maize seed. The most important of them are fungi. Blotter method and method of nutrient medium were used to examine the seed health of 90 maize seed samples from eight seed processing centres in the period 2006-2008. The presence of fungi from the genera Fusarium, Penicillium, Aspergillus and Rhizopus was observed on maize seed. According to current regulations, level of infection caused by the fungi observed in all three years was within the normal limits. The percentage of infected samples was 45% in 2006, 40% in 2007, and 32% in 2008. Percentage of infection ranged from 0.25% to 5% in samples where the presence of fungi of the genus Fusarium was detected, while the percentage of infection on maize seed caused by the fungi from saprophite group (Penicillium spp., Aspergillus spp. and Rhizopus spp.) ranged within the limits of 0.25% to 15%.
