Coffee Leaf Rust Disease Detection and Implementation of an Edge Device for Pruning Infected Leaves via Deep Learning Algorithms [PDF]

Sensors
Global warming and extreme climate conditions caused by unsuitable temperature and humidity lead to coffee leaf rust (Hemileia vastatrix) diseases in coffee plantations. Coffee leaf rust is a severe problem that reduces productivity. Currently, pesticide

Hemileia vastatrix in Coffea spp.: Distribution of Urediniospores Grouped by Size and Insights into Morphological Structures [PDF]

Journal of Fungi
Hemileia vastatrix coffee leaf rust reduces Mexican coffee production by 51%. We aimed to analyze the size and distribution of H. vastatrix urediniospores among coffee plantations, as well as the morphological structures of the uredinium.

Isolation and identification of antagonistic fungi on coffee leaf rust in the Dieng highlands of Banjarnegara, Indonesia

Egyptian Journal of Biological Pest Control, 2023
Background Coffee is an important plantation crop in Indonesia. The coffee cultivation process was disrupted due to the fungus Hemileia vastatrix which causes rust disease. Biological control has the potential to suppress disease development.

Role of Mineral Elements to Induce the Resistance of Arabica Coffee Against Rust Disease at Lowland Area [PDF]

E3S Web of Conferences, 2020
Lowland arabica coffee can be affected by leaf rust and its decrease the coffee production up to 80%. The resistance level of the plant can be determined by the content of cellulose, lignin, calcium pectate, and polyphenols in leaf tissue.
