Citrus foot rot disease (Phytophthora spp.) control in Indonesia using good agricultural practices efforts green agroindustry

Abstract

Foot Rot (Phytophthora spp.) is an important disease in Indonesia and in the world. Around 35% of citrus plantations have been damaged by the complex of foot rot disease and Diplodia disease (Botryodiplodia theobromae), mainly in swamps and irrigated fields. The spread of the disease is fast, but the knowledge of citrus farmers is still limited, causing rapid death in production plants. This paper purpose is to provide an overview of the citrus root disease control from research studies supporting the efforts of Good Agricultural Practices in Indonesia. Usually farmers only rely on systemic pesticides to control disease, but it is not always successful. Control by means of healthy cultivation is highly recommended in supporting green agroindustry and saving nature. Integrated and rational control strategies, require knowledge of the ecology and epidemic of diseases ranging from seedlings to gardens. Propagule pathogens can survive in seeds, tree stumps, soil, even in alternative hosts. Therefore, to control the disease it must be directed not only to oranges but also to alternative hosts as well and to destroy pathogenic retention sites. The recommended integrated control strategy is to use disease-resistant plants, making sewers, garden sanitation, and optimal maintenance. This method is very effective and environmentally friendly.
