Résumé :
Biological efficacy of strobilurines (trifloxystrobin and kresoxim-methyl) was evaluated to compare the effect of late treatments of apples against post-harvest diseases with the effect of widely used reference products (captan, tolylfluanid, dithianone, dodine). One treatment 3–4 weeks before the harvest was applied (1000 l/ha water). Tested and reference products were used in doses authorised in the Czech Republic against the apple scab (Venturia inaequalis). Strobilurines effectiveness overcame all the products compared and showed an effect on reduction of weight decrease during the storage. In total 8 field tests were performed in 2000–2004 were efficacy, effect on fruit quality and weight decrease during storage was assessed.

Résumé :
The strobilurins and the closely related oudemansins are new respiration inhibitors, binding to the Qp centre of cytochrome b. Their high antifungal activity against phytopathogenic fungi and their low toxicity towards mammals make them attractive lead compounds for the synthesis of agricultural fungicides. The strobilurins have been isolated from a great number of Basidiomycetes belonging to the genera Strobilurus, Oudemansiella, Xerula, Hydropus, Mycena, Filoboletus, Crepidotus, and Cyphellopsis as well as one Ascomycete, Bolinea lutea. Strobilurin-producing species occur in Europe, the Americas, Africa, and Australia. Most of the producing fungi grow on wood. Since under sterile conditions strobilurin production could be detected in the natural substrate it appears that the strobilurins play a role in securing nutrient resources for the producers from competing fungi. Key words: strobilurins, oudemansins, antibiotics, antifungal, Basidiomycetes.

Résumé :
Resistance to strobilurin fungicides was documented in isolates collected from three fungicide efficacy experiments conducted in research fields in Georgia (GA), North Carolina (NC), and New York (NY). In these fields in 2002, strobilurins (fungicide group 11, quinone outside inhibitors [QoI]) when used alone on a 7-day schedule (use pattern not labeled) did not effectively control cucurbit powdery mildew. Strobilurin efficacy declined dramatically after the second application in New York (3). Efficacy also was reduced in commercial fields in Kentucky and research fields in Arizona, California, Kentucky, Illinois, Michigan, and Virginia in 2002 where strobilurins were used predominantly or exclusively. Isolates were collected on 22 July and 8 and 17 October after the last of four, five, and five applications of strobilurin (trifloxystrobin formulated as Flint or azoxystrobin formulated as Quadris) in experiments conducted by J. D. Moore in Chula, GA, M. McGrath in Riverhead, NY, and G. J. Holmes in Clayton, NC, respectively. A leaf-disk bioassay was used to determine fungicide sensitivity (2). Strobilurin sensitivity was determined using trifloxystrobin at 0, 0.5, 5, 50, and 100 μg/ml. Four of nine NY isolates, 19 of 21 GA isolates, and 13 of 15 NC isolates were resistant to strobilurins (grew well on disks treated with trifloxystrobin at 100 μg/ml). The geometric mean of the azoxystrobin baseline was 0.258 μg/ml for Podosphaera xanthii isolates collected in 1998 and 1999 in North America (4). Poor control with strobilurins under field conditions was associated with reduced sensitivity in vitro. Strobilurin sensitivity appeared to be qualitative as reported elsewhere (1). Two sensitive and three resistant isolates responded similarly when tested in another laboratory using kresoxim-methyl and pyraclostrobin (H. Ypema, personal communication). These findings and experiences elsewhere with QoI-resistant P. xanthii indicate that cross-resistance probably extends among multiple QoI's (1). Strobilurins have been available for commercial use in the United States since 1998, when azoxystrobin received Section 18 registration in some states. Federal registration was granted in March 1999. Strobilurin resistance was detected after 2 years of commercial use elsewhere in the world (1). All isolates tested in the current study were from research fields where selection pressure for resistance could have been higher than in commercial fields where strobilurins are used with demethylation inhibitors (DMIs; fungicide group 3) and contact fungicides in alternation or tank mixtures to prevent or delay resistance development. Resistance in commercial fields will reduce the utility of strobilurins, including those not yet registered, and eliminate an important tool for managing DMI resistance. Strobilurins and DMIs are the only systemic fungicides registered for cucurbit powdery mildew in the United States. Managing DMI resistance may be challenged by multiresistant strains. Strobilurin-resistant isolates also exhibited reduced sensitivity to DMIs, tolerating triadimefon at 50 to 100 μg/ml (2). One suggestion to improve resistance management is to apply a contact fungicide with strobilurins as well as DMIs. References: (1) H. Ishii et al. Phytopathology 91:1166, 2001. (2) M. T.

Résumé :
Aim of this study was to investigate the sensitivity of conidia of Spilocaea pomi to main fungicide active ingredients (cyprodinil, pirimethanil, fluquinconazole, tebuconazole, difenoconazole, dodine és trifloxistrobin) at dosages of 0.5, 1 and 2 times incubated in vitro at 24 and 48 hours collected from three integrated apple orchards. Results showed that degree of conidial germinations at the fungicide treatnemts decreased in the order of dosages of untreated, 0.5, 1 and 2 times. Considerable conidial germination was observed at higher dosages of some fungicides (e.g. groups of strobilurines and EBI) which confirmed the possibilities of sensitivity reduction of Spilocaea pomi to some funigicides in the sampled Hungarian apple orchards.

Résumé :
The research was carried to study the effect of fungicides of various classes on the intrapopulation structure of Pyrenophora teres in terms of sensitivity to toxicants, virulence and racial composition. The work was performed using eight treatment options in different doses (control without fungicide, 25 %, 50 %, 75 %, 100 % (the norm), 125 %, 150 %, 175 %, 200 %) fungicides Magnello, EC (1 l/ha), Capella, M (1 l/ha), Kolosal Pro, MC (0.4 l/ha), Quadris, SC (1.2 l/ha), Amistar Trio, EC (1 l/ha), Orgamika C, L (0.4 l/ha) of plants and introduction to a nutrient medium with a pure culture of P. teres. The racial composition of the populations was determined using an international set of differentiator varieties. When treating plants with fungicides with the norm allowed for use in agriculture, the minimum efficiency values were found in the preparations Quadris, SC (52.3 %), Orgamika C, L (66.8 %), the maximum - Magnello, EC (88.2 %) and Kolosal Pro, MC (97.0 %). The average virulence of the population isolated after Quadris, SC treatment was revealed to be maximum - 3.4 points (at the control level). The greatest racial diversity was found in P. teres populations isolated after treatment with fungicides based on triazoles Magnello, EC (CF=0.10) and strobilurines Quadris, SC (CF=0.10). The maximum intrapopulation heterogeneity was revealed in populations isolated after treatment with fungicides based on triazoles and Bacillus amyloliquefaciens: Kolosal Pro, MC (Sh=2.16), Capella, M (Sh=2.14), Magnello, EC (Sh=2.10)) and Orgamika C, L (Sh=2.12). When introducing the permitted rate of drugs into the pure culture of P. teres, on average, the growth of colonies slowed down from 86.1 % (Quadris, SC) to 100 % (Amistar Trio, EC). Preparations based on strobilurines and Bacillus amyloliquefaciens completely prevented sporulation. The results obtained allow us to conclude that there is a shift in sensitivity to the studied drugs.

Résumé :
The increasing emergence of fungicide-resistant pathogens requires urgent solutions for crop disease management. Here, we describe a structural investigation of new fungicides obtained by combining strobilurin and succinate dehydrogenase inhibitor pharmacophores. We identified compounds endowed with very good activity against wild-type Pyricularia oryzae, combined in some cases with promising activity against strobilurin-resistant strains. The first three-dimensional model of P. oryzae cytochrome bc1 complex containing azoxystrobin as a ligand was developed. The model was validated with a set of commercially available strobilurins, and it well explains both the resistance mechanism to strobilurins mediated by the mutation G143A and the activity of metyltetraprole against strobilurin-resistant strains. The obtained results shed light on the key recognition determinants of strobilurin-like derivatives in the cytochrome bc1 active site and will guide the further rational design of new fungicides able to overcome resistance caused by G143A mutation in the rice blast pathogen.

Résumé :
Strobilurin is a group of natural products and their synthetic analogs have been widely used to control and prevent fungal diseases. Strobilurins were firstly isolated in 1977 from the mycelium of Strobilurus tenacellus, a saprobic Basidiomycete fungus causing wood-rotting on forest trees. This group of pesticides was designed to manage fungal pathogens classes such as Ascomycetes, Basidiomycetes, and Oomycetes. Also, Strobilurin commercialized included derivatives such as are azoxystrobin, kresoxim-methyl, picoxystrobin, fluoxastrobin, oryzastrobin, dimoxystrobin, pyraclostrobin and trifloxystrobin. This group is a part of the larger group of QoI inhibitors, which act to inhibit the respiratory chain at the level of Complex III. Strobilurins group control an unusually wide array of fungal diseases, included water molds, downy mildews, powdery mildews, leaf spotting and rusts. This group are used on cereals, field crops, fruits, tree nuts, vegetables, turfgrasses and ornamentals. Also, Strobilurins found to enhance the plant growth in some cases.

Résumé :
The use of strobilurin fungicides in agriculture has increased steadily during the past 25 years, and although strobilurins have minimal water solubility, they regularly appear in surface waters, at times in concentrations approaching toxic levels for aquatic life. The present study examined concentrations of strobilurin fungicides in designated trout streams draining an agricultural watershed in southeastern Minnesota, USA, where fungicides may have contributed to a recent fish kill. Water samples (n = 131) were analyzed for the presence of five different strobilurin fungicides (azoxystrobin, fluoxastrobin, picoxystrobin, pyraclostrobin, trifloxystrobin). Samples were collected via grab and automated sampling during baseflow and stormflow events throughout an entire crop-growing season from sites on each of the three forks of the Whitewater River. Detection frequencies for the five strobilurins ranged from 44 to 82%. Fluoxastrobin and pyraclostrobin concentrations were above known toxic levels in 3% and 15% of total samples analyzed, respectively. The highest concentrations were detected in mid-summer (mid-June to mid-August) samples, coincident with likely strobilurin applications. Lower concentrations were present in water samples collected during the nonapplication periods in spring and fall, suggesting groundwater–stream interactions or steady leaching of fungicides from watershed soils or stream sediments. Further study is required to determine strobilurin concentrations in sediments, soils, and groundwater. Better tracking and guidance regarding strobilurin use is necessary to adequately protect aquatic life as fungicide use continues to increase.

Résumé :
The effect of fungicide class strobilurine on "effect gardening" plants is undeniable. Most research on this class of drugs focuses on their effects on plant growth and physiology. There is little information about the effect of strobilurine on the rheological properties of the dough when applied to wheat. In our work, we tried to identify their role. The objects of the study were 5 varieties of spring soft wheat, with different grain and flour quality. To study the effect strobilurins was selected fungicide containing pyraclostrobin + epoxiconazole. The use of a preparation based on pyraclostrobin does not lead to a strong change in the grain quality and rheological properties of the dough in rust-resistant varieties, this indicates that strobilurins almost do not affect the grain quality. In varieties that are highly and medium susceptible to leaf-stem diseases, not only the yield increases significantly, but also the grain quality and rheological properties of the test improve when using a fungicide based on pyraclostrobin 62.5 g/l + epoxiconazole 62.5 g/l at a dose of 1.5 l/ha.

Résumé :
Les cancers du rein et de la vessie sont classés parmi les 10 cancers les plus fréquents dans le monde et leur incidence est plus élevée dans les pays occidentaux. L'étiologie professionnelle de ces deux cancers a été étudiée, largement pour la vessie mais pas suffisamment dans le milieu agricole. De plus, les familles chimiques spécifiques et les substances actives impliquées dans cette relation restent insuffisamment étudiées. Le cancer du rein est encore moins exploré dans ce contexte, bien que certaines études épidémiologiques aient mis en évidence un lien potentiel avec certains pesticides. L'étude AGRICAN représente l'une des plus vastes études de cohorte sur la santé des travailleurs en milieu agricole, regroupant plus de 180 000 participants depuis 2005. Les résultats ont révélé des associations positives entre l'exposition à certaines matières actives et le risque de cancers du rein et de la vessie. Pour le cancer du rein, un risque accru a été observé chez les hommes traitant le colza et le tournesol, ainsi que chez ceux utilisant des pesticides sur le tabac. Les urées substituées ont été identifiées comme une famille chimique préoccupante pour le rein et la vessie. En effet,nos résultats montrent une association positive notable entre l’exposition au métobromuron et le cancer du rein ; le risque doublant après plus de 30 ans d'exposition. Les analyses ont également mis en lumière des associations positives pour ce cancer avec des SDHI, tels que le mépronil, dont l'utilisation était associée à un risque accru, notamment pour les sujets exposés pendant 10 à 15 ans. Aucune association n’a été trouvée avec l’utilisation de strobilurines. En ce qui concerne le cancer de la vessie, des associations positives ont été observées chez les non-fumeurs utilisant des phénylurées, tandis que chez les ex-fumeurs, des associations inverses ont été notées. Cependant, chez les fumeurs, une tendance à l'augmentation du risque a été observée avec certaines phénylurées lorsqu'ils étaient comparés à des groupes d'exposition plus faibles. Des limites liées à la co-exposition à d'autres substances et à l'introduction récente de certains pesticides sur le marché doivent également être prises en compte. Ces résultats soulignent l’existence d’un lien entre l’exposition professionnelle aux pesticides et le risque de cancers du rein et de la vessie. L'identification des urées substituées comme substances préoccupantes met en lumière la nécessité de continuer les recherches, en particulier pour mieux comprendre l'impact de ces substances sur la santé des agriculteurs. À la lumière de ces résultats, il est essentiel de renforcer les efforts de recherche et les initiatives de santé publique visant à réduire l’exposition aux pesticides et à d’autres risques en milieu agricole, afin de protéger la santé des agriculteurs. Il est également crucial de porter une attention aux femmes travaillant dans le secteur agricole, afin de mieux appréhender les risques associés à leur exposition
Kidney and bladder cancers rank among the ten most common cancers globally, with higher incidence rates observed in Western countries. The occupational etiology of these two cancers has been studied, particularly for bladder cancer, but remains insufficiently explored within the agricultural sector. Furthermore, the specific chemical families and active substances involved in this relationship are not adequately investigated. Kidney cancer, in particular, has received even less attention in this context, although some epidemiological studies have suggested a potential link with certain pesticides. The AGRICAN study represents one of the largest cohort studies on the health of agricultural workers, encompassing over 180,000 participants since 2005. In this study, the results revealed positive associations between exposure to specific active substances and the risk of kidney and bladder cancers. For kidney cancer, an increased risk was observed among men treating rapeseed and sunflower crops, as well as among those using pesticides on tobacco crops. Substituted ureas were identified as a concerning chemical family for kidney and bladder health. Metobromuron showed a notable positive association with kidney cancer; the risk doubled after more than 30 years of exposure. The analyses also highlighted positive associations for this cancer with SDHIs, such as mepronil, whose use was associated with an increased risk, particularly for those exposed for 10 to 15 years. No association was found between the use of strobilurins and kidney cancer. Regarding bladder cancer, positive associations were observed among non-smokers using phenylureas, while inverse associations were noted among ex-smokers. However, among smokers, a trend towards increased risk was observed with certain phenylureas when compared to groups with lower exposure. Limitations related to co-exposure to other substances and the recent introduction of certain pesticides to the market must also be considered. These results underscore the existence of a link between occupational exposure to pesticides and the risk of kidney and bladder cancers. The identification of substituted ureas as concerning substances highlights the need for continued research, particularly to better understand the impact of these substances on farmers' health. In light of these results, it is essential to strengthen research efforts and public health initiatives aimed at reducing exposure to pesticides and other risks in agricultural settings to protect farmers' health. It is also crucial to pay attention to women working in the agricultural sector to better understand the risks associated with their exposure

Texte intégral
Résumé :
Mycosphaerella graminicola (anamorphe: Septoria tritici) constitue aujourd’hui l’agent pathogène le plus fréquent et le plus dévastateur sur les cultures de blé. Cinq cent dix souches de ce parasite ont été isolées à partir de 16 localités géographiques réparties sur les plus grandes régions productrices de blé en France. Le mating-type de chaque souche a été déterminé par "PCR multiplex". La distribution équilibrée des deux matingtypes suggère une fréquence élevée de la reproduction sexuée au sein de la population française du pathogène. Une analyse du polymorphisme moléculaire par PCR-RFLP-SSCP et séquençage a révélé une grande conservation des idiomorphes des mating-types chez M. Graminicola ainsi qu'un niveau de polymorphisme plus important pour l’idiomorphe mat1-2 comparativement à l’idiomorphe mat 1-1. Un criblage conduit pour 42 souches a mis en évidence une variabilité importante du pouvoir pathogène. Une étude cytologique et enzymatique menée in planta a démontré que le pouvoir pathogène chez M. Graminicola n’est expliqué ni par le taux de germination des spores, ni par la croissance sur la surface foliaire et ni par la fréquence des pénétrations directes ou stomatiques de l’hôte, mais par sa capacité à coloniser le mésophylle et à produire l’enzyme de dégradation des parois cellulaires l’endo-1,4-ß-xylanase durant la phase nécrotrophe. Une caractérisation complémentaire réalisée pour 82 souches a confirmé l’implantation de la résistance aux strobilurines au sein de la population française du champignon et a montré la présence d’un gradient nord-sud pour la distribution de la résistance. Cette dernière étude a permis la validation de quatre méthodes d’évaluation de la résistance de M. Graminicola aux strobilurines
Mycosphaerella graminicola (anamorph : Septoria tritici) is today the most frequently occuring and the most economically damaging pathogen on wheat crops. Five hundred and ten strains of this fungus were isolated from 16 geographical locations covering most of the wheat producing areas in France. The mating type of each strain was determined by multiplex PCR. The equal distribution of the two mating types suggests regular cycles of sexual recombination within French population of the pathogen. A sequence polymorphism analysis using both PCR-RFLP-SSCP and sequencing revealed high conservation of the two mating type idiomorphs in M. Graminicola, with a more important level of polymorphism in the mat1-2 idiomorph compared to the mat 1-1 idiomorh. A sreening of 42 strains by disease level assessment showed a great variability in pathogenicity among strains. Cytological and enzymatic assays conducted in planta highlighted that M. Graminicola pathogenicity is not correlated to either rate of spore germination, mycelial growth on leaf surface or frequency of host leaf penetration, but linked to its ability to colonize the mesophyll and to produce the cell wall degrading enzyme endo-1,4-ß-xylanase during necrotrophic phase. Further investigations performed with 82 strains confirmed the widespread occurence of resistance to strobilurin fungicides within this French population of M. Graminicola and showed the presence of north-south gradient of the resistance distribution. This later study allowed the validation of four in vitro methods assessing M. Graminicola resistance to strobilurins

Résumé :
Brazil is the first soybean producer in the world, and the largest exporter. In the 2019/20 harvest, the country produced about 124.85 million tons, representing 30% of world production. Global soy production for 2019/20 reached 337.9 million tons. Asian soybean rust (ASR) is the most pathogen on soybean in Brazil in nowadays. Target spot and Septoria leaf spot plus white mold complete these scenarios. ASR emerged in Brazil in 1979. The use of fungicides in the soybean crop in Brazil intensified after the master of 2002 with the resurgence of soybean rust, where the use of triazoles intensified. The massive sprays to pathogen control reached 3.5 sprays per season. In 2006, the first reports of loss of sensitivity of the fungus to the group appeared, notably for the fungicide flutriafol and tebuconazole used in many situations in a curative way or to eradicate the fungus. From that moment on, the productive system sought to use triazoles and strobilurins. In 2011 came the first reports of loss of sensitivity of the fungus in the group of strobilurins. This fact was due to the use of pyraclostrobin in the vegetative phase of soybeans without protection by multisite. That same year, the introduction of the active ingredients in copper oxychloride, mancozeb and chlorothalonil took place in Brazil. In 2015, the first carboxamides ((benzovindiflupyr) (solatenol and fluxpyroxade) associated in triple mode with triazoles and strobilurins were launched on the Brazilian market. Due to the specific mode of action in the metabolism of the fungus (biosynthesis of ergosterol (triazoles), mitochondrial respiration in the cytochrome oxidase enzyme complex - QOIs (strobilurins) and succin dehydrogenase - SDHIs (carboxamides), the need for their association in the sprayings was seen. To multisite (cuprics, dithiocarbamates and nitriles). For the sustainable management of the disease in Brazil, control strategies are recommended, such as the use of systemic fungicides, with a specific biochemical mechanism of action with the adoption of tank mix with multisite, adoption of cultural practices (sanitary emptiness) and sowing schedule and the use of varieties with quantitative resistance (partial or horizontal resistance). These measures will guarantee the sustainability of the culture and the useful life of systemic fungicides or specific sites.

Résumé :
Since the introduction in the late 1960s of systemic fungicides with modes of action involving inhibition of single target sites, resistance to many of these products has evolved in populations of fungal pathogens. Many important pathogens have developed reduced sensitivity to many of the major classes of systemic fungicide used in agriculture and horticulture. This chapter reviews mechanisms of resistance to the most widely-used, broad-spectrum groups of fungicide over the last 50 years, including methyl benzimidazole carbamate (MBC) fungicides, azoles, amines including morpholines and piperidines, succinate dehydrogenase inhibitors (SDHI) and quinone-outside inhibitors (QoI, often known as strobilurins). For each class of fungicide we will discuss the fungal target and explore how resistance operates at the gene and protein level. We focus on powdery mildews as an example because they are one of the major fungal groups against which systemic fungicides are applied, and because they are notorious for the speed at which they have evolved resistance to most of the major classes of fungicide.
