Abstract:
Fungi belonging to five genera, Monosporascus sp., Pythium aphanidermatum, Rhizoctonia solani, Olpidium sp., Fusarium solani, and F. proliferatum, were the species most frequently isolated from the root systems of wilted melon. Diseased plants were collected from 24 fields in the northern and central Arava region of southern Israel during the fall seasons of 1994 and 1995. In pathogenicity tests conducted under field conditions, in artificially inoculated microplots, the first wilt symptoms were observed at various stages of fruit maturation. High mortality levels (73 to 97%) were recorded for

Abstract:
In the beginning of the 1970’s, the occurrence of soil-borne viruses in 30 Finnish nurseries and experimental fields of garden plants at 3 research stations was mapped. Viruses were isolated on 26.9 % of the 672 plant and soil samples collected. The two most commonly found viruses were tobacco necrosis virus (TNV), 42.5 %, and tobacco rattle virus (TRV), 23.7 %. Tomato black ring virus (TBRV) and raspberry ringspot virus (RRSV) were isolated for the first time in Finland. The abundant occurence of TBRV in 32 samples was due to the abundance of Phlox paniculata samples. RRSV was isolated from o

In the spring of 2008, freesia, cvs. Honeymoon and Santana, with striking virus-like symptoms similar to freesia leaf necrosis disease were received by the Virginia Tech Plant Disease Clinic from a cut-flower nursery in Gloucester, VA and forwarded for analysis to the USDA-ARS Floral and Nursery Plants Research Unit in Beltsville, MD. Approximately 25% of the plants had coalescing, interveinal, chlorotic, whitish, necrotic or dark brown-to-purple necrotic spots on leaves. Symptomatic plants were scattered within the planting. Fifteen symptomatic plants were collected between March and May of 2

Abstract:
In the 1995 to 1996 season, severe viral disease symptoms were observed on carnations (Dianthus caryophyllus [hybrid Kooij Echo kgr]) propagated from imported seedlings on farms in central Taiwan. Disease symptoms began on upper leaves as numerous yellow spots that enlarged and fused into large chlorotic patches and expanded to cover entire leaves, which eventually became necrotic. Electron microscopy of crude extracts, purified preparations, and ultrathin sections of diseased tissues revealed the presence of isometric particles ≈32 to 33 nm in diameter.

Abstract:
Fertilization management can affect plant performance and soil microbiota, involving still poorly understood rhizosphere interactions. We hypothesized that fertilization practice exerts specific effects on rhizodeposition with consequences for recruitment of rhizosphere microbiota and plant performance. To address this hypothesis, we conducted a minirhizotron experiment using lettuce as model plant and field soils with contrasting properties from two long-term field experiments (HUB-LTE: loamy sand, DOK-LTE: silty loam) with organic and mineral fertilization history.

Abstract:
The rhizosphere microbiome is considered to play a key role in determining crop health. However, current understanding of the factors which shape assembly and composition of the microbiome is heavily biased toward bacterial communities, and the relevance for other microbial groups is unclear. Furthermore, community assembly is determined by a variety of factors, including host genotype, environment and agricultural management practices, and their relative importance and interactions remain to be elucidated. We investigated the impact of nitrogen fertilization on rhizosphere bacterial, fungal,
