Abstract


Maize (Zea mays L.) is best known cereal crop extensively grown all over the world and it is considered as third major crop of Pakistan. The consumption demand of corn is continuously increasing day by day mainly increasing in the demand by starch sector and poultry sector. In the following sectors it is used as the feed. Seed borne pathogens produce foremost types of the seed diseases. Few fungi species associated with corn are mostly belongs to Aspergillus and Fusarium species. These studies indicate that dangerous mycotoxin was produced by fungi species which are harmful for both human and animal health. Industries scrap such seeds because of their ineffectiveness in agricultural purposes. Mycoflora which was associated by seeds both externally and internally was responsible for seed borne diseases. In this study fungi associated with maize grains from different samples at different moisture level was isolated and identified. After that different chemical compounds were evaluated for the management of isolated fungal species. The research was helpful for farmers in choosing the optimum time of harvesting as well as in selection of best chemical product for the management of disease. Data obtained from each parameter was subjected to analysis of variance. Results showed that all the selected cultivars showed a different type behavior of germination for distinctive moisture levels and mean value for each hybrid was substantially different due to the fungicide application. In the application of carbendazim, the Hybrid 6714 gave minimum score (81.33%) followed by Hybrid 6789 (84.66%), Hybrid P1543 (86.33%), Hybrid 30Y87 (87.33%). The seed treated with difenoconazole the Hybrid P1543 gave maximum score (84.66%) followed by Hybrid 30Y87 (80.33%), Hybrid 6714 (76%) and Hybrid 6789 (81%). The seed treated Metalaxyl +Mancozeb the Hybrid 30Y87gave maximum score (77%) for control followed by Hybrid P1543 (76.67%), Hybrid 6789(74.33%) and Hybrid 6714 (71%).

Key words: Maize, mycoflora, moisture level
