“…nystatin (100 mg dm -3 ) treatment combination was the most effective treatment against fungal contaminants. Similar results were obtained by Barnett and McGilvary (2001) and Allen et al (2004). Barnett and Varela (2004) tested many chemicals to reduce large populations of microorganisms on longleaf pine (Pinus palustris).…”

Ziziphus spina [christti] is a naturally distributed tree in subtropical, arid and semi-arid parts of Iran. It is ecologically and economically important due to its tolerance to drought and salinity. Most tree seeds are infected with parasitic and saprophytic microorganisms which decrease the seed germination and seedling establishment. The goal of this paper was to evaluate the ability of selected chemical solutions to inhibit the growth of variety of microbial contaminants in Z. spina Contaminants were identified according to their morphological and cultural characteristics. Bacterial contaminants included Xanthomonas sp. While Fungal isolates were Fusarium, Penicillium, Alternaria, Rhizopus, and Aspergillus. Our experiment reveals that 4% NaOCl followed by benomyl is the best sterilization treatment for Z. spina [christti] seeds, since the highest number of germination and highest number of sterilized seeds was observed after this treatment.

“…In already mentioned study of Müllenborn et al (2008), different ED 50 values were recorded for seven different Fusarium species grown on media with prothioconazole, tebuconazole, azoxystrobin and fluoxastrobin. Differences in reaction of different Fusarium species to the fungicides in vitro was also recorded in the study of Allen et al (2004), where Fusarium solani was inhibited by 60% on difenconazole amended media, while Fusarium circinatum, F. oxysporum and F. proliferatum were inhibited by 90%. Indirect evidence for different sensitivity of different Fusarium species to a certain fungicide are shown in studies of Pirgozliev et al (2002) and Simpson et al (2001).…”

SUMMARYGrowth of 13 F. graminearum isolates, 6 F. avenaceum isolates and 6 F. verticillioides isolates was analysed on potato-dextrose agar amended with 0.1, 0.33, 1, 3.3 and 10 mg l -1 of carbendazim, tebuconazole, flutriafol, metconazole, and prochloraz. Average concentration which reduced mycelial growth by 50% comparing it to control (EC 50 ) was calculated for each isolate. Among fungicides tested, prochloraz was shown to be the most effective in growth inhibition of all three species, while flutirafol was proven to be the least effective. Metocnazole was more efficient in comparison with carbendazim and tebuconazole. EC 50 values of all isolates on prochloraz were lower than 0.1 mg l -1 , while on flutirafol they ranged between 1.66 and 8.51 mg l -1 for 18 isolates, or were higher than 10 mg l -1 for 7 isolates. EC 50 values on carbendazim were 0.39-1.41 mg l -1 for F. graminearum isolates, 0.91-1.35 mg l -1 for F. avenaceum, and 0.47-0.6 mg l -1 for F. verticillioides. EC 50 values on tebuconazole were 0.85-2.57 mg l -1 for F. graminearum, 0.85-1.58 mg l -1 for F. avenaceum and 0.22-0.85 mg l -1 for F. verticillioides, while on metconazole EC 50 values ranged between less than 0.1 mg l -1 to 1.66, 0.56, and 0.17 mg l -1 for F. graminearum, F. avenaceum and F. verticillioides, respectively. Average growth inhibitions of different Fusarium species and all Fusarium isolates together on different concentrations of fungicides tested were significantly different. Significant differences in growth were not determined among isolates of the same species on neither one of fungicides tested, indicating that no decreased sensitivity to the fungicides exists among isolates included in the study.

“…Our experiment showed that, prochloraz and bromuconazole at the concentration of 10 µg/ml were the most effective, followed by benomyl and carbendazim that had good preventive and curative effects on tomato wilt. Allen et al (2004) revealed that benomyl at 10 µg/ml (a.s.) completely inhibited fungal growth of F. solani, F. oxysporum and F. proliferatum. Etebarian (1992) reported that, iprodione + carbendazim, benomyl and carbendazim totally inhibited fungal growth at the concentrations of 10 and 100 ppm, after 10 days.…”

Tomato fusarium wilt is considered as one of the most important diseases of tomato both in field and greenhouse -grown tomatoes worldwide. In presented research, six fungicides; benomyl, carbendazim, prochloraz, fludioxonil, bromuconazole and azoxystrobin, were evaluated for their efficacy against the disease casual agent Fusarium oxysporum f. sp. lycopersici in vitro and in vivo. Seven different concentration (0.0001, 0.001, 0.01, 0.1, 1, 10, 100 µg/ml) were used for assessment of their inhibitory activities against the pathogen through mycelial growth inhibition on potato media. Four concentrations of above mentioned fungicides (0.1, 1. 10 and 100 µg/ml) were tested for controlling Fusarium wilt on tomato plants in glasshouse. Fungal radial growth was measured and median effective concentration (EC 50 ) values (µg/ml) determined. The result of glasshouse tests revealed a different degree of efficacy of all tested fungicides in reducing disease infestation. Prochloraz and bromuconazole were the most effective fungicides against the pathogen both in vitro and in vivo, followed by benomyl and carbendazim. All other fungicides were less effective. Conserning the application date of fungicides it was shown that they were less effective when applied 7 days after tomato plant infection, compared with 1 day prior infection. No phytotoxic symptoms were observed after the application of prochloraz, bromuconazol and benomyl when used at recommended doses, especially on seedlings. However both fungicides fludioxonil and bromuconazole were shown to be phototoxic to tomato seedlings.
