Grain corn is the main source of feed for livestock in Malaysia, especially chickens and pigs, as most of the livestock feed products have a grain corn composition between 45% and 65%. To fulfil the needs, Malaysia targets to reduce the importation of grain corn from foreign countries such as Argentina, Brazil, the United States, Thailand, Myanmar, Pakistan and Indonesia by achieving a 30% national self-sufficiency rate (SSL) in 2040. Efforts in many aspects, including research, have been put in. In this study, the focus was given to the identification and control of fungal pathogens that caused major diseases in grain corn. Monitoring of the disease was carried out in a farmers’ field at FELDA, Chuping, Perlis. The effectiveness of in vitro control methods using chemical fungicides showed the potential of Propiconazole to control the growth of Bipolaris sp. and Curvularia sp. Field trial results also showed Propiconazole significantly reduced the leaf spot diseases. The results of this study will be shared in the Grain Corn Cultivation Manual as a guide to grain corn entrepreneurs and farmers to reduce the problem of fungal disease attacks that can affect the crop yield.
