An optimized method for in vitro production of Verticillium dahliae microsclerotiaSpringer Science and Business Media LLC - - 2013
Xiaoping Hu, Yinwen Bai, Ting Chen, Dongfang Hu, Jiarong Yang, Xiangming Xu
Verticillium dahliae causes wilt disease of many crops worldwide. Microsclerotia
are the main resting structure of V. dahliae in soil and can survive for more
than 10 years, serving as an important source of primary inoculum. Mass
production of microsclerotia in laboratory is valuable for studying various
aspects of V. dahilae, such as its biology, epidemiology and control. We failed
to produce a ... hiện toàn bộ
Uncommon disease symptoms caused by Fusarium oxysporum in tulips forced in the glasshouse after pre-cooling at 5°CSpringer Science and Business Media LLC - Tập 75 - Trang 100-104 - 1969
P. K. Schenk, B. H. H. Bergman
Rapidly developing disease symptoms not normally found in tulip bulb cultivation
in The Netherlands are described. Mycelium of the fungus is present mainly in
the parenchymatic tissues, giving further evidence that the fungus is not a
vascular parasite in tulips. There are indications that enzymes or other
compounds are involved in the syndrome. Possible factors influencing this
uncommon disease d... hiện toàn bộ
Trichoderma harzianum T39 and T. virens DAR 74290 as Potential Biological Control Agents for Phytophthora erythrosepticaSpringer Science and Business Media LLC - Tập 106 - Trang 329-337 - 2000
H.R. Etebarian, E.S. Scott, T.J. Wicks
Trichoderma harzianum isolate T39 and T. virens isolate DAR 74290 were evaluated
as potential biological agents for control of pink rot of potato and root and
stem rot of tomato caused by Phytophthora erythroseptica. Cell-free metabolites
of T. virens DAR 74290 completely inhibited growth of P. erythroseptica in vitro
and appeared to be fungicidal. T. virens DAR 74290 and Trichodex, a commercial

De voetziekte van Gerbera, veroorzaakt door Fusarium oxysporum SchlechtSpringer Science and Business Media LLC - - 1952
J. A. von Arx
Gerbera jamesonii Hook hybr. is grown under glass in the Netherlands for the
sake of its valuable flowers; cultivation is difficult, as many of the plants
die. The short stem, which bears a rosette of leaves, becomes discoloured,
blackens and putrefies, while the leaves and flowers wither. Several fungi have
been isolated from the rotting stems — mostlyFusarium oxysporum (Schlecht.)

Characterization of Fusarium nirenbergiae and F. elaeidis causing diseases on Dipladenia and Grevillea plantsSpringer Science and Business Media LLC - Tập 162 - Trang 885-896 - 2022
Dalia Aiello, Giorgio Gusella, Alessandro Vitale, Giancarlo Polizzi
During 2019, severe symptoms of crown, basal stem and root rot associated with
vascular discoloration were observed on Dipladenia and Grevillea ornamental
species in a nursery located in Southern Italy. Fusarium spp. colonies were
consistently recovered from infected tissues on semi-selective media. Molecular
and phylogenetic analyses of the internal transcribed spacer (ITS) of rDNA, RNA
polymeras... hiện toàn bộ
‘Hollow noses’ in hyacinth, a disorder caused by the herbicide chlorprophamSpringer Science and Business Media LLC - Tập 78 - Trang 198-203 - 1972
P. J. Muller, J. van der Boon
A malformation in hyacinths, first observed in recent years, was found to be an
effect of uptake by the roots of the herbicide chlorpropham. The risk of this
malformation is even present when normal doses of this compound are used for
weed killing, especially on sandy soils with very little organic matter and
under conditions of shallow planting. De laatste jaren wordt in hyacinten een
onbekende a... hiện toàn bộ
A microscopic study of powdery mildew on barley after application of the systemic compound wepsynSpringer Science and Business Media LLC - Tập 72 - Trang 274-278 - 1966

5-Amino, 3-phenyl, 1-bis (dimethylamido) phosphoryltriazole 1, 2, 4 (wepsyn) was
applied to the roots of barley seedlings, var. ‘Balder’ in concentrations of 10,
25, 62 and 156 ppm, and the infection process ofErysiphe graminis f.sp.hordei on
these plants studied microscopically. During the first few hours after
inoculation a retardation of the germination occurred at the two highest
