Fungicide-resistant Alternaria alternata impede the practical control of the Alternaria diseases in crop fields. This study aimed to investigate cytological fungicide resistance mechanisms of A. alternata against dicarboximide fungicide iprodione. A. alternata isolated from cactus brown spot was cultured on potato-dextrose agar (PDA) with or without iprodione, and the fungal cultures with diffe...

Cinnamic, p-coumaric and ferulic acids were isolated from pineapple stems (Ananas comosus var. Cayenne). Twenty-four kinds of esters were prepared from these acids, alcohols and the components of Alpinia. Isopropyl 4-hydroxycinnamate (11) and butyl 4-hydroxycinnamate (12) were found to have almost the same effectiveness in antifungal activity against Pythium sp. at 10 ppm as that of the commerc...

Searching for alternative methods to conventional pesticides against crop pathogens is an important challenge. In this way, we tested the potential of hops extracts to be used as a bio-fungicide towards Zymoseptoria tritici, the main pathogen on wheat crops in France and Europe. Hops is known for its numerous biological properties such as antiviral, antibacterial and antifungal potential for hu...

The fungicide rapamycin increases lifespan in eukaryotes by interfering with the activity of a serine/threonine kinase called TOR (target of rapamycin). TOR complex 1 (TORC1) is an essential integrator of cellular nutrient cues, growth signals and cellular metabolism. Here, we review major components of TORC1, its downstream effectors and lifespan studies in various organisms involving these si...

Commercial rhododendron plants have been the most important hosts of Phytophthora ramorum in Europe. As part of the European Union (EU) emergency phytosanitary measures 2002/757/EU and 2004/426/EU all commercial rhododendron-growing premises are surveyed for P. ramorum. Detection of P. ramorum leads to quarantine measures, including destruction of plants, and could lead to considerable financia...

The non-target effect of the fungicide Quadris R on bacterial community from grassland loamy sand (LS) and cropland clay loam (CL) soils with unknown history usage was investigated. applied to soil mesocosms at 0.0 mg kg -1 (Az0), 2.90 (Az1), 14.65 (Az2) 35.0 (Az3) calculated towards active ingredient azoxystrobin (Az). Response communities investigated during a 120-day incubation experiment, e...
