“…Humans, as well as crops and livestock, are susceptible to be infected by pathogenic fungi (5,36,67). Fungi are also one of the main problems associated with food spoilage, because fungal growth on raw and processed foods produces the deterioration of their sensorial properties, rotting, off-flavor, and odor emission (70).…”

Synthetic food additives generate a negative perception in consumers. This fact generates an important pressure on food manufacturers, searching for safer natural alternatives. Phytochemicals (such as polyphenols and thiols) and plant essential oils (terpenoids) possess antimicrobial activities that are able to prevent food spoilage due to fungi (e.g., Aspergillus, Penicillium) and intoxications (due to mycotoxins), both of which are important economic and health problems worldwide. This review summarizes industrially interesting antifungal bioactivities from the three main types of plant nutraceuticals: terpenoids (as thymol), polyphenols (as resveratrol) and thiols (as allicin) as well as some of the mechanisms of action. These phytochemicals are widely distributed in fruits and vegetables and are very useful in food preservation as they inhibit growth of important spoilage and pathogenic fungi, affecting especially mycelial growth and germination. Terpenoids and essential oils are the most abundant group of secondary metabolites found in plant extracts, especially in common aromatic plants, but polyphenols are a more remarkable group of bioactive compounds as they show a broad array of bioactivities.

“…Indirect impacts include increased costs to control the disease. Control methods include fungicide application [11], cultural practices [5] including stumping of diseased plants, the use of resistant cultivars [3], and biocontrol by fungal and bacterial parasites [4,39]. These methods induce significant labor and material costs and, in the case of stumping, a year-long decline in production.…”

“…Some other models investigate CLR control. Vandermeer et al look at the interaction between H. vastatrix and a mycoparasite Lecanicillium lecanii [39], while Arroyo et al consider interactions with antifungal bacteria [4]. However, no existing CLR model considers H. vastatrix dynamics together with its interaction with the coffee host.…”

Coffee leaf rust ( CLR ) is one of the main diseases that affect coffee plantations worldwide . It is caused by the fungus Hemileia vastatrix . Damages induce severe yield losses (up to 70% ). Its control mainly relies on cultural practices and fungicides , the latter having harmful ecological impact and important cost . Our goal is to understand the propagation of this fungus in order to propose a biocontrol solution, based on a mycoparasite that inhibits H.~ vastatrix reproduction. We develop and explore a spatio -temporal model that describes CLR propagation in a coffee plantation during the rainy and dry seasons . We show the existence of a solution and prove that there exists two threshold parameters , the dry and rainy basic reproduction numbers , that determine the stability of the equilibria for the dry and rainy season subsystems . To illustrate these theoretical results , numerical simulations are performed , using a non-standard finite method to integrate the pest model . We also numerically investigate the biocontrol impact. We determine its efficiency threshold in order to ensure CLR eradication .

“…The rust cycle begins with the deposition and germination of uredospores on the leaves; the infection depends on several environmental and physiological factors of the plant, although the main ones are the amount of rainfall, temperature, age of leaves and inoculant (Nutman and Roberts, 1963). Uredospores are scattered throughout a plantation by the wind or the splashing of rainwater (Nutman and Roberts, 1963;Rayner 1961;Arroyo et al, 2018). Rust reduces the photosynthetic ability of plants and the development of the new sprouts in the next planting cycle.…”

“…An alternative for the management of rust is the genetic resistance of the varieties. The hybrid Catimor and the variety Robusta have proven to be more tolerant to the disease than the variety Arabiga; however, tolerance is rarely effective against all the Fully Bilingual Revista Mexicana de FITOPATOLOGÍA Mexican Journal of Phytopathology de lluvia (Nutman y Roberts, 1963;Rayner 1961;Arroyo et al, 2018). La roya reduce la capacidad fotosintética de la planta y el desarrollo de los nuevos brotes en el siguiente ciclo de cultivo.…”

La roya del cafeto (Hemileia vastatrix) es una enfermedad devastadora para los cafetales en México. Los métodos de control se han centrado en el uso de fungicidas, pero sin éxito, por lo que el control biológico representa una alternativa. Las larvas de Mycodiplosis se reportan como depredadoras de H. vastatrix, pero la información disponible sobre este insecto es limitada. Los objetivos de esta investigación fueron describir el tipo de relación entre H. vastatrix y Mycodiplosis y conocer su patrón de distribución en el dosel de la planta. Se eligieron tres plantaciones con incidencia de roya en Xochitlán de Vicente Suárez, Puebla y se registraron periódicamente la severidad de la roya y el número de larvas de Mycodiplosis por estrato de la planta. Se seleccionaron 25 plantas por parcela, muestreada en cinco de oros. Las larvas se identificaron molecularmente. Mediante la prueba de Kruskal Wallis, se encontraron diferencias significativas entre sitios de muestreo en la severidad de roya y el número de larvas de Mycodiplosis, detectando una correlación positiva entre la severidad de la roya y el número de larvas de Mycodiplosis. La distribución de Mycodiplosis fue similar en los estratos (baja, media y alta) de las plantas evaluadas.
