In vitro testing was conducted to evaluate the inhibition potential of three compost teas (pine bark, manure, and vermicasting), Root Rescue Landscape Powder® (a mix of mycorrhizae and other beneficial microbes), waste diatomaceous earth (DE; from beer brewing), and a greenhouse nutrient solution, which had been reused for 20 years on six plant pathogens: Fusarium foetens, Rhizoctonia solani, Sclerotinia sclerotiorum, Phytophthora cryptogea, Pythium intermedium, and P. ultimum. The test materials showed in vitro inhibition on most of the test pathogens. Pine bark tea suppressed growth of all six pathogens, and inhibition exceeded 50% after 10 days of coincubation. Vermicasting tea showed over 40% inhibition against S. sclerotiorum and F. foetens; manure tea showed 42% inhibition against F. foetens; DE showed 40% inhibition against F. foetens, S. sclerotiorum, and R. solani; whereas reused greenhouse nutrient solution showed 56.7% inhibition against R. solani and 43.4% inhibition against F. foetens; Root Rescue showed 66% inhibition against P. intermedium. The results suggest that the six test materials have potential in the control of these soil- and water-borne pathogens in plant production system.

Fusarium foetens is a destructive vascular pathogen on Begonia, mainly on cultivars of Begonia elatior hybrids (Begonia × hiemalis), which has recently been identified in Europe and Northern America (1,3). This Fusarium species has been responsible for severe damage in the begonia flower industry (1) and is listed as an EPPO A2 quarantine pathogen since 2007. In May 2007, wilted potted plants of B. elatior showing chlorotic leaves and basal stem rot were observed in a nursery located in the west of France (La Flèche, Sarthe). Symptomatic foliar and basal stem pieces were plated on a Fusarium semi selective medium, dichloran chloramphenicol peptone agar (DCPA), and on malt agar medium supplemented with 100 ppm chloramphenicol. Homogeneous mycelium of a Fusarium species developed from both types of tissue and on both media, and was transferred to potato dextrose agar (PDA) and to spezieller nährstoffarmer agar (SNA) media for morphological examination. Microscope slides were then prepared by pressing gently a clear self-adhesive tape onto the surface covered by mycelium and sporodochia, which was further stained with lactic acid/methylene blue. Typical multiseptate (often three septa), hyaline, slightly curved Fusarium macroconidia 29.2 to 41.8 (32.5) × 3.6 to 4.5 (4.3) μm were collected in sporodochia. In the aerial mycelium, long and short conidiophores with mono- or polyphialidic cells bearing false heads of ellipsoidal microconidia were observed. In addition, a pungent distinctive odor was produced by the mycelium grown on PDA. These features were consistent with F. foetens (2). To support the diagnosis, total DNA was further extracted from the pure culture and a partial region of the translation elongation 1 (tef1) gene was amplified by PCR using EF1-EF2 primer pair (4). Nucleotide sequence was determined and deposited on GenBank (Accession No. JX298790). Analysis of the sequence by BLAST showed that it was 100% identical with all the available F. foetens sequences, which confirmed our morphological diagnosis. To our knowledge, this is the first official report of F. foetens in France. Since this first detection, F. foetens was again identified in 2010 in another nursery located in the Pays de la Loire on collapsed B. elatior. Approximately 15 to 20% of the Begonia plants showed typical Fusarium wilt symptoms and the infected lots were systematically destroyed. The origin of these infections could not be traced back since the mother plants tested negative. The disease is considered as eradicated in France but causes major economic losses to Begonia growers and marketers in regions where the disease is established (2). References: (1) H. Huvenne et al.

Hiemalis begonias Fotsch (Begonia × hiemalis), a member of the family Begoniaceae, is a commercially important potted flowering plant in Europe and North America. In the spring of 2010, stunted growth and dull green leaves of H. begonias were observed in a commercial greenhouse in southern Ontario, Canada. Symptoms began with dull green foliage, followed by wilted leaves, then the stem base became water soaked with vascular discoloration, and finally, large macroconidial masses of a fungus developed on the collapsed stems and veins. A fungus was consistently isolated from the leaves, stems, and roots of symptomatic plants. Single conidia were isolated from sporodochia and cultured on potato dextrose agar (PDA) and oatmeal agar (OA) for 7 days. Isolates exhibited strong pungent odors on PDA and OA and a brownish orange colony on OA and a light orange colony on PDA. Masses of light orange and hemispherical-shaped conidia and stromata formed on OA. Conidiophores formed from aerial mycelium producing ellipsoidal microconidia without septation. Sporodochia formed on agar surface producing three-septate, slightly curved macroconidia. The cultural and conidial characteristics of the isolates were similar to those of Fusarium foetens Schroers (4). Partial translation elongation factor 1-α (TEF) gene was amplified and sequenced with primers ef1 and ef2. A comparison of a partial sequence has been deposited in GenBank (Accession No. HM748968) and showed a 100% match with F. foetens (2). Inoculations with F. foetens isolates were performed by injecting a 100-μl suspension of 1 × 106 conidia/ml into stems of five healthy plants near the ground or soaking the soil of five healthy 6-week-old H. begonias cv. Golden Edith with 50 ml of suspension. Control plants were similarly injected with sterile water or sown in sterile soil. After 4 weeks, all inoculated plants developed dark, wilting leaves and collapsed stems and veins similar to those observed in the commercial greenhouse. F. foetens was reisolated from diseased plants, and identification was reconfirmed by conidial characteristics and TEF 1-α sequence. Control plants were healthy and symptom free. F. foetens has recently been described in association with a new disease of H. begonias in Europe (3) and the United States (1). F. foetens can cause major economic losses to farmers and marketers of H. begonias in Europe and the United States. To our knowledge, this is the first report of F. foetens causing wilt disease of H. begonias in Canada. References: (1) W.-H. Elmer et al. Plant Dis. 88:1287, 2004. (2) D.-M. Geiser et al. Eur. J.

Fusarium Foetens

During 2003, 10% of the Hiemalis begonias (Begonia × hiemalis Fotsch) developed wilt symptoms in a commercial greenhouse in Connecticut. Foliage turned a dull green, and stems developed a dark watersoaked discoloration near the soil line and had vascular discoloration. Stems, petioles, and leaves collapsed and became covered with sporodochia of a Fusarium spp. Single conidia were isolated from sporodochia and cultured on carnation leaf agar (CLA) and potato dextrose agar for 10 days. Isolates resembled Fusarium oxysporum, but the profuse sporulation with minimal aerial mycelium and the rare occurrence of polyphialides was consistent with the description of F. foetens (2). A comparison of a partial sequence of the 1-α elongation factor gene showed a 100% match with F. foetens. Inocula from five isolates were grown on CLA, washed from the plate, and adjusted to 106 conidia per ml. Suspension (50 μl) was injected into stems of healthy 6-week-old Hiemalis begonias cv. Barkos (one plant per isolate). Controls received distilled water. After 4 weeks, all inoculated plants turned dark and collapsed, and the same fungus was reisolated from these plants. Control stems remained healthy. An isolate (O-2348) has been deposited at the Fusarium Research Center at Pennsylvania State University, University Park. F. foetens has recently been described in association with a new disease of Hiemalis begonias in Europe (1). References: (1) R. Schrage, Phytomedizinischen Gesellschaft 33:68, 2003. (2) H.-J.
