Influence of Selected Fungicides on in vitro Growth of Artillery Fungi (Sphaerobolus spp.)

Abstract We tested the inhibitory effect of 14 fungicides, 13 of which were known to be effective against the basidiomycete Agaricus, at 5 and 20 ppm on the in vitro growth of three species of artillery fungi: Sphaerobolus iowensis, S. stellatus, and a previously undescribed Sphaerobolus sp. Captafol, epoxiconazole, thiophanate-methyl, triflumizole, and triphenyltin acetate were the most effective inhibitors against all three Sphaerobolus species, and the reduction in growth was directly related to fungicide concentration. Chloroneb, chlorothalonil/zinc oxide, fuberidazole, glyodin, and tolylfluanid showed varying results, depending on fungal species and fungicide concentration; however, they were much less effective than the previous five fungicides. Dazomet, dinocap, folpet, and ferbam failed to slow the growth of any artillery fungi at either concentration. This preliminary study revealed that certain fungicides suppress growth of artillery fungi and should be further tested in the field.

This study which designed to evaluate the inhibitory effect of Ethanolic extract of (Quercusrobur) and Zinc oxide nanoparticles on the growth of one genus of enterobacteriacae (Salmonella). In vitro. For this purpose graduate concentrates for plant extract (50, 100, 200, 400 )mg/ml which prepared and compared with Zinc oxide nanoparticles of different concentration (2, 1, 0.5, 0.25) μg/ml,and examined. The result showed that the studied medicinal plant has antibacterial activity against this bacteria which used. The result showed that the plant has good activity in decrease the growth of this bacteria. The results of the study also showed that the nano-ZnO has very effective antibacterial action against the studied bacteria which was Salmonella,nanoparticles concentrations lead to increasing in the inhibition zones of tested bacterial growth. We also study the effect of three antibiotics Lomefloxacin (LOM), Ciprofloxacin (SIP) and Rifampin (RA) and the result showed,in a comparison within the tested bacteria,Salmonella had a significant inhibition increase in Lomefloxacin ; the ciprofloxacin showed effect on tested bacteria. However,Rifampin does not show any effect on tested bacteria.

Cladosporium Herbarum

The interactions between six commonly occurring fungal species in damp or water-damaged houses in southern California were studied. These fungal species were Alternaria alternata, Aspergillus niger, Chaetomium globosum, Cladosporium herbarum, Penicillium chrysogenum and Stachybotrys chartarum. In the damp building materials, S. chartarum was found to be associated with A. niger, C. globosum, and P. chrysogenum but not with A. alternata and C. herbarum. Stachybotrys chartarum showed strong antagonistic effect against A. alternata and C. herbarum and significantly inhibited in vitro growth of A. alternata and C. herbarum but had no effect on A. niger, C. globosum, and P. chrysogenum. Two trichothecenes, produced by S. chartarum, trichodermin and trichodermol, significantly inhibited spore germination and in vitro growth of A. alternata and C. herbarum but had no effect on A. niger, C. globosum, P. chrysogenum and S. chartarum. In the damp building materials (drywall, ceiling tile, and oak woods), S. chartarum significantly inhibited the growth of A. alternata and C. herbarum and had no effect on the growth and colonization of A. niger, C. globosum, P. chrysogenum in these substrata.

Monilinia fructicola and Monilinia laxa are the most destructive fungal species infecting stone fruit (Prunus species). High-throughput cDNA sequencing of M. laxa and M. fructicola isolates collected from stone fruit orchards revealed that 14% of isolates were infected with one or more of three mycoviruses: Sclerotinia sclerotiorum hypovirus 2 (SsHV2, genus Hypovirus), Fusarium poae virus 1 (FPV1, genus Betapartitivirus), and Botrytis virus F (BVF, genus Mycoflexivirus). Isolate M196 of M. fructicola was co-infected with all three viruses, and this isolate was studied further. Several methods were applied to cure M196 of one or more mycoviruses. Of these treatments, hyphal tip culture either alone or in combination with antibiotic treatment generated isogenic lines free of one or more mycoviruses. When isogenic fungal lines were cultured on nutrient agar medium in vitro, the triple mycovirus-infected parent isolate M196 grew 10% faster than any of the virus-cured isogenic lines. BVF had a slight inhibitory effect on growth, and FPV1 did not influence growth. Surprisingly, after inoculation to fruits of sweet cherry, there were no significance differences in disease progression between isogenic lines, suggesting that these mycoviruses did not influence the virulence of M. fructicola on a natural host.
