The production of ornamental plants in Mexico represents a job-generating activity that has grown in recent years; however, it is adversely affected by phytosanitary issues, notably those induced by Phytophthora. Studies of Phytophthora in ornamental nurseries are scarce in Mexico. The aim in this study was to identify Phytophthora species from sel...

Traditional farming heavily relies on agrochemicals including mineral fertilizers and pesticides, which are known for their detrimental effects on ecosystems and soil health, especially when these chemical inputs are applied excessively. We conducted two field experiments to compare conventional, integrated and agroecological farming systems, as we...

En México, la citricultura representa una de las actividades económicas más importantes para la fruticultura nacional, con una producción de 8.8 millones de toneladas y una derrama económica de más de 47 mil millones de pesos al año. Sin embargo, la producción se ve afectada por plagas y enfermedades, destacando el Huanglongbing (HLB), ‘dragón amar...

Horticultural Production Systems (HPS) in Mexico face challenges due to small-scale operations, limited resources, and high dependence on family labor. This study explores the use of agrochemicals in HPS and its impact on productivity and potential exposure to pesticides. Through on-farm surveys in the Morelia-Queréndaro valley, Central Mexico, fac...

El propósito de esta compilación es dar a conocer al investigador, protocolos fundamentales que se emplean para el aislamiento, diagnóstico e identificación de Phytophthora spp., cubriendo aspectos generales del género para una mejor comprensión y análisis del mismo. Esta información será de utilidad para investigadores que trabajan con enfermedade...

The presence of both mating types of Phytophthora species in the same pot has not been reported in hosts of commercial nurseries in Mexico. Isolates of Phytophthora were collected in commercial nurseries of Mexico City and Morelos state during 2015. Mating types A1 and A2 of Phytophthora capsici and P. drechsleri were detected on wilted plants of C...

p>No se ha reportado la presencia de ambos tipos de compatibilidad de especies de Phytophthora en plantas hospedantes sembradas en una misma maceta en viveros comerciales de México. En 2015, se colectaron aislados de Phytophthora en viveros comerciales en la Ciudad de México y en el estado de Morelos. Se detectaron los tipos de compatibilidad A1 y...

Big-leaf mahogany (Swietenia macrophylla) is valued for its high-quality wood and use in urban landscapes in Mexico. During surveys of mango-producing areas in the central western region of Mexico, symptoms of malformation, the most important disease of mango in the area, were observed on big-leaf mahogany trees. The objectives of this research wer...

Malformation is the most important disease of mango in Mexico. It affects floral and vegetative shoots, and reduces fruit production. Although several species of Fusarium cause the disease worldwide, F. mexicanum is most important in Mexico. To better understand epidemiology of disease in Mexico, we studied mango nurseries as a source of infected p...

Mango is one of the most important fruit crops in Mexico. However, the production of this crop is severely affected by the malformation disease in most growing areas of the country. Mango malformation is the most important disease in the state of Michoacan for this fruit crop. Mango production in Michoacan is reduced from 40 to 50% by the malformat...

Two anamorphic powdery mildews (Erysiphales) on Senna spp., recently found in Mexico, have been morphologically and genetically examined, as well as subjected to pathogenicity tests. Powdery mildew on Senna occidentalis proved to belong to the Podosphaera xanthii complex (P. xanthii s. lat.), and another collection on S. septemtrionalis has been id...

Carrot (Daucus carota L. subsp. sativus (Hoffm.) Arcang.) is planted as a home-grown vegetable in the central region of Michoacan, Mexico. Powdery mildew was observed on carrot plants cv. Nantesa at several locations near Morelia, Michoacan during March 2009. Affected plants had abundant, white, superficial conidia and mycelium on leaves and stems....
