“…This test examined five arabica coffee clones, namely Komasti, Maragogik, USDA, Andong sari, and HDT (Hybrido de Timor) clones consisting of 10 replications within each treatment and two sample plants in each replication. The prepared suspension of H. vastatrix spora was sprayed on the leaves of coffee clones with spraying concentration of 10 -3 (Mudyiwa et al, 2017) H.vastatrix ml -1 using a sprayer. Incubation was carried out for 4 weeks and symptoms in the leaves were observed.…”

Indicator of coffee resistance to leaf rust attack (Hemileia vastatrix) is needed to select superior coffee plants resistant to biotic stress. This study aims to find the relationship between the content of secondary metabolites and the intensity of leaf rust attack, so that it becomes a reference in the selection of future coffee plants. The experimental design used was a completely randomized design (CRD) with several coffee clones as a treatment. This test tested 5 Arabica coffee clones consisting of Komasti, Maragogik, Usda, Andong sari, and HDT clones. Each consists of 3 replications, and each replication consists of 2 sample plants. Observations were made by observing the intensity of the attack, and plant metabolites such as phenolic content, flavonoids and antioxidant activity were observed when the leaves had been attacked by Hemileia vastatrix. Correlation of leaf rust attack levels with phenolic content, flavonoids and antioxidant activity showed a relationship between each observation variable. Flavonoid content in certain conditions can be used as an indicator to get Arabica coffee plants that are resistant to the attack of leaf rust.

Coffee leaf rust (CLR) is caused by the biotrophic fungus Hemileia vastatrix Berk. & Br., a disease of economic importance, reducing coffee yield up to 60%. Currently, CLR epidemics have negatively impacted food security. Therefore, the objective of the present research study is to show a current framework of this disease and its effects on diverse areas, as well as the biological systems used for its control, mode of action, and effectiveness. The use of essential plant oils and antagonistic microorganisms to H. vastatrix are highlighted. Terpenes, terpenoids, and aromatic compounds are the main constituents of these oils, which alter the cell wall and membrane composition and modify the basic cell functions. Beneficial microorganisms inhibit urediniospore germination and reduce disease incidence and severity. The antagonistic microorganisms and essential oils of some aromatic plants have great potential in agriculture. These biological systems may have more than one mechanism of action, which reduces the possibility of the emergence of resistant strains of H. vastatrix.

“…The inhibitory effect may be due to the alkaloid (nicotine) compound, insecticidal and antifungal. The results indicated that increasing the active ingredient increases spore germination inhibition [ 68 ]. The use of plants as an alternative for rust control has been previously investigated.…”

Hemileia vastatrix (HV) is the pathogen responsible for the coffee leaf rust (CLR) disease that has spread globally. CLR causes losses of up to a billion dollars annually and affects all types of crops regardless of their production regime (organic or inorganic). Additionally, smallholders produce approximately 80% of coffee in developing countries. The condition causes losses of up to a billion dollars annually. It affects all types of crops regardless of their production regime (organic or inorganic). Approximately 80% of coffee is produced by smallholders in developing countries. Until the 90s, shaded-production systems and native varieties were encouraged; however, the rapid spread of CLR has forced farmers to migrate towards inorganic schemes, mainly due to a lack of knowledge about natural alternatives to pesticides that can be implemented to control HV. Therefore, the purpose of this article is to compile the currently existing options, emphasizing two key factors that guarantee efficient rust control: selective fungicidal activity against HV and the nutrition of coffee crops. Thus, by comprehending how these natural compounds (such as plant, bacteria, fungi, animals, or algae metabolites) impact coffee rust proliferation. Furthermore, since a various range of biochar effects contributes to the control of foliar fungal pathogens through modification of root exudates, soil properties, and nutrient availability, which influence the growth of antagonist microorganisms, we present a review of the pathogen-suppressive effects of biochar, and new control strategies suitable for organic schemes can be developed.
