“…This could be due to the possible inhibition of lactobacilli growth in presence of higher amounts of pesticide . Overall, the results obtained are in accord with numerous publications concerning the role of microbes in pesticide degradation in different food commodities . Boethling noted that if microbial degradation does occur, it is likely to result from enzymatic activity and may either occur immediately or only after a period of adaptation to the chemicals.…”

“…Residual analysis of these two fungicides usually requires several pretreatment steps. Common pretreatment techniques include solid-phase microextraction (Otero et al 2002;Melo et al 2012) and liquid-liquid extraction (LLE; González-Rodríguez et al 2011;Čuš et al 2010). However, the LLE method is time consuming and laborious and requires large amounts of organic solvents.…”

A simple and accurate method coupled with a gas chromatography-nitrogen phosphorus detector was developed to detect cyprodinil and fludioxonil in grape and soil. The accuracy and precision of the method in detecting the two fungicides were evaluated by conducting intra- and inter-day recovery experiments. The limits of detection were 0.017 mg/kg for cyprodinil and 0.030 mg/kg for fludioxonil. The limits of quantitation were 0.05 mg/kg for cyprodinil and 0.10 mg/kg for fludioxonil in grape and soil. The recoveries of the fungicides in grape and soil were investigated at three spiked levels and were found to range from 85.81 to 102.94% for cyprodinil and from 92.00 to 106.86% for fludioxonil, with relative standard deviations below 7%. Field experiments were conducted in two experimental locations in China. The half-lives of cyprodinil were 9.6-20.8 days in grape and 5.8-15.6 day in soil, and the half-lives of fludioxonil were 6.2-7.2 days in grape and 6.0-12.1 days in soil. When the cyprodinil and fludioxonil 62% water-dispersible granule formulation was sprayed at a low dosage three times, terminal residues of cyprodinil and fludioxonil were below 1.0 mg/kg in grape 14 days after harvest. This work may serve as a reference to establish the maximum residue limits for cyprodinil and fludioxonil in grape and promote the proper and safe use of these two fungicides.

“…Grapevine plants were treated with penconazole (Support 10 EC, 10.2% penconazole; Cheminova Agro Italia, Bergamo, Italy) at a concentration of 0.3 ml/liter or with the biocontrol agent AZ78 at a concentration of 10 6 CFU/ml, while other plants were left untreated. Penconazole is a widely used chemical fungicide, principally adopted against powdery mildews (25,26), and it has a broad range of activity against ascomycetes and basidiomycetes (27). Penconazole was chosen in our experiments because it is not active against the oomycetes (27); thus, it is not expected to affect the efficacy tests against Plasmopara viticola on leaf disks.…”

The phyllosphere is colonized by complex microbial communities, which are adapted to the harsh habitat. Although the role and ecology of nonpathogenic microorganisms of the phyllosphere are only partially understood, leaf microbiota could have a beneficial role in plant growth and health. Pesticides and biocontrol agents are frequently applied to grapevines, but the impact on nontarget microorganisms of the phyllosphere has been marginally considered. In this study, we investigated the effect of a chemical fungicide (penconazole) and a biological control agent (Lysobacter capsici AZ78) on the leaf microbiota of the grapevine at three locations. Amplicons of the 16S rRNA gene and of the internal transcribed spacer were sequenced for bacterial and fungal identification, respectively. Pyrosequencing analysis revealed that the richness and diversity of bacterial and fungal populations were only minimally affected by the chemical and biological treatments tested, and they mainly differed according to grapevine locations. Indigenous microbial communities of the phyllosphere are adapted to environmental and biotic factors in the areas where the grapevines are grown, and they are resilient to the treatments tested. The biocontrol properties of phyllosphere communities against downy mildew differed among grapevine locations and were not affected by treatments, suggesting that biocontrol communities could be improved with agronomic practices to enrich beneficial populations in vineyards. Plants support a complex micro-ecosystem, and they host distinct bacterial communities on and inside various plant organs (1). The aerial part of plants (phyllosphere) is normally colonized by a variety of bacteria, filamentous fungi and yeasts (2). Microbial phyllosphere communities are complex and composed by many uncultured microorganisms (2, 3), which are adapted to the harsh environmental conditions (4, 5). In particular, microbial epiphytes of the phyllosphere are exposed to the atmosphere and must deal with direct UV radiation, wide fluctuations in temperature, low water availability, and limited access to nutrients (2,6). Therefore, the composition of phyllosphere communities could be affected by environmental factors, such as UV radiation, air pollution, and nitrogen fertilization, as well as by biotic factors, such as plant species and invading microorganisms (6-8). Moreover, the phyllosphere is an open system and microbes can invade plant leaves by migration from the atmosphere, soil, other plants, insects, and animals (9).The phyllosphere has been less intensively studied than the rhizosphere and has received considerable attention in recent years (1). The interest in phyllosphere microbiology was initially driven by investigations into plant pathogens, but most phyllosphere-colonizing microorganisms live as commensals and/or mutualistic symbionts on their host plants (2,4,6). Phyllosphere communities are involved in functional processes as large in scale as the carbon cycle, nitrogen fixation, and degradation of organic pollu...
