Natural products obtained from plants constitute an alternative to chemically synthesized fungicides, whose improper use might have caused the development of resistant fungal strains. In the present work, 40 products obtained from 20 native Argentinean plant species were tested against three citrus postharvest pathogens: Penicillium digitatum, Peni...

El higo es un fruto climatérico con gran perecibilidad y corta vida poscosecha. Presenta un ostiolo que sirve como medio de polinización y sitio de entrada de patógenos fúngicos. En este trabajo se evaluaron tres diferentes estrategias de protección y su efecto en el desarrollo del ostiolo además de la presencia de hongos. Se utilizaron 15 plantas...

The main pathogen that deteriorates the quality of rose flowers during the postharvest stage belongs to the fungal genus Botrytis. The chemical products used to control the disease caused by this pathogen have been losing effectiveness due to the appearance of resistance. The present study describes the in vitro and in vivo fungicidal activity of P...

The discovery of new pharmaceutical identities, particularly anti-infective agents, represents an urgent need due to the increase in immunocompromised patients and the ineffectiveness/toxicity of the drugs currently used. The scientific community has recognized in the last decades the importance of the plant kingdom as a huge source of novel molecu...

El empleo constante y excesivo de fungicidas sintéticos en la industria fruti-hortícola ha provocado profundas alteraciones en el medio ambiente y en la salud humana. En este contexto, explorar fuentes naturales antifúngicas resulta de importancia económica y medioambiental. Se propuso estudiar la actividad de cinco aceites volátiles obtenidos de l...

Background: One of the main problems that fruit health has gone through in recent years is the difficult eradication of their fungal pathogens during crops or the post-harvest stage. This concerns the whole world because it represents huge production losses, fruit export restrictions and consumer distrust. Consequently, new alternatives are sought...

The discovery of new antifungal compounds is an urgent need due to the increase of immunocompromised patients and the ineffectiveness/toxicity of existing drugs in clinical use. The plant kingdom represents a huge source of novel molecules and particularly the Argentine Republic has great plant diversity and only a small percentage of which has bee...

One of the main problems that fruit health goes through in recent years is the difficult eradication of their fungal pathogens after harvesting. This concern to the whole world because it represents huge losses of production, fruit export restrictions and consumers distrust. One of the alternatives to solve this problem could be the exploration of...

rea: Ciencias Naturales INTRODUCCIÓN La podredumbre marrón es una grave enfermedad causada por el patógeno fúngico Monilinia fructicola, que afecta a los frutos de carozo desde el período de floración hasta las etapas de poscosecha y almacenamiento (Martini y Mari, 2014). Su amplia diseminación resulta en grandes pérdidas económicas que van desde...
