Effect of benomyl on soil, root-surface and leaf-surface fungi

Effect of Kocide and Ridomil plus fungicides on the mycoflora of tomato plant in Upper Egypt

“…Aspergillus flavus, A. fumigatus, A. niger, A. terreus, Cochliobolus spicifer, Emericella nidulans, Fusarium oxysporum, Gibberella fujikuroi, Nectria haematococca, Penicillium chrysogenum, P. oxalicum and Rhizopus stolonifer were the most common fungi and their counts were decreased or completely eliminated by all doses after different periods of treatment, except in some cases, the counts were not affected or increased (Tables 7 and 8). Similar findings have been reported by Abdel-Kader et al (1983), Platt (1983), Moubasher et al (1984), Nan et al (1991) and Moharram et al (2004).…”

“…Genera & species except in some cases, the counts were increased (Tables 5 and 6). The selective effect of various fungicides on these fungi was recorded by numerous researchers including DeBertoldi et al (1978), Abdel-Kader et al (1983), Moubasher et al (1984) and Moharram et al (2004).…”

“…In this respect, Abdel-Kader et al (1983) reported that the fungicide Tridemorph regularly inhibited the total count of Vigna sinensis phyllosphere fungi at all three doses after 10 days until the end of experiment. Moubasher et al (1984) reported that Benomyl was regularly toxic to the total count of phyllosphere fungi and the toxicity persisted until the end of the experiment.…”

“…They showed that the fungicide Tridemorph exerted a toxic effect on the total and individual counts of Vigna sinensis rhizosphere fungi with the three doses used after all periods of treatment. Moreover, Moubasher et al (1984) investigated the efffect of Benomyl fungicide on rhizosphere soil fungi and reported that Benomyl was significantly toxic to the total count of rhizosphere fungi at the three doses used after most experimental periods.…”

“…In this respect, Abdel-Kader et al (1983) found that the fungicide Tridemorph depressed the total count of Vigna sinensis rhizoplane fungi and the effect persisted for 40 days. Moubasher et al (1984) found that the fungicide Benomyl was generally toxic to the total count of rhizoplane fungi of Vigna sinensis. Nan et al (1991) reported that the total populations of fungi on the roots of red clover plants from pots treated with prochloraz fungicide at concentration 240 mg/kg dry soil (at 20 and 258C) were lower than those from untreated controls.…”
