New book tree dying in Germany - ever more private plants concerned
Gardner of Eden Jörg crowd weber from Hambug cuts a Buchsbaum and hopes for the fact that its existence is not endangered
(openPR) - mildness weather and continuous sheet wetness promote mushroom infection. Trip is a new mushroom with the designation Cylindrocladium buxicola. Damage with hygiene measures, trimming and aids contain
Gütersloh, 15.01.07 - the Buchsbaum is in private gardens a very popular and wide-spread evergreen ornamental shrub. Artful formed Solitär wood, as ball, appears cone, Kubus or as hedge or surface as. Already letzen late summers showed up European-wide new cases of the book tree dying. With laboratory tests as trip a mushroom with the designation Cylindrocladium was diagnosed buxicola, which hardly stepped into Germany so far into feature. Now the illness spreads also in Germany due to the mild weather and long lasting wet-with-rain one rapidly. The mushroom exclusively arises at Buchsbaum, whereby the sorts are considered „blue Heinz “as susceptible and „to Suffruticosa “as particularly susceptible. In addition, other sorts are more durable, an infestation can occur here. The diagnosis does not remain simple for the layman, apart from hygiene measures helps only chemical aids and the experience of the specialist.
Very frequently an alleged Cylindrocladium emerges buxicola - infestation as one of Volutella buxi caused illness, also as „a book tree cancer “designates. Pale-green sheet discolorations, dying impulses and branches from otherwise vital plants are also here at the beginning of. An infestation with Volutella is to be recognized to lightpink sheets died to apricot farbene Sporenbelag on the lower surface. Also the mushroom Fusarium buxicola can lead to completely similar dying features, it is however rarely diagnosed. A trained view and much experience are here in demand.
The infestation with the new mushroom Cylindrocladium buxicola is only difficult to get. Most important symptoms are usually dark-brown marks on the blade lower surfaces, which flow together with progressive disease process, in addition come later a bright, mehliger Sporen lining. If mainly the recent parts of this year of the plants are concerned, appear to marks rather orange-brown with dark edge. From stricken impulses dark, nearly black strips are recognizable: Finally it comes to sheet loss and also to driving inheriting. Already 1997 gave it a first infestation wave in England. Also from France, Holland, Belgium and Ireland gives it increases notices of loss.
Roland Lütkemeyer, refining confining age and executive committee of the gardners of Eden in Gütersloh: „In the private garden we have to care for often valuable book planting and Buchssolitärs, there are large the shock with infestation. Generally take we suspects or obviously got sick to plants of the dealer not on. Black discolorations of the impulses and sheet loss are here important alarm signals. With infestation of the garden we see a supporting addition of the classical hygiene measures in the employment of chemistry only - it cannot replace these however. A fungicide spectrum is still tested, because there is no special means in the trade. Up to then the specialist of the confidence is in demand, who has the safe eye and which knows conservative techniques “
Otherwise one can hope for a hot summer: The optimal growth conditions for the mushroom are at temperatures to 25°C, higher lead to a drastic break-down; a continuously hot summer should reduce the infestation clearly. A risk remains: the mushroom forms also microscopic continuous pores out (Chlamydosporen), which can provide for an outlasting of several years. A reason more to proceed and the plants strengthen professionally. Who controls promptly and which introduces appropriate measures, must thus no total loss of its loved and expensive book plant fear.
7 fight recommendations
Because hardly sufficiently effective preventing and welfare-end preparations admits are, hygiene measures must be kept strictly, in order the probability of infestation and - duration as small as possible to keep. Also radical Roden can be indicated. The gardners of Eden give recommendations:
Sort choice consider: When particularly susceptibly the sort Buxus must apply sempervirens for “Suffruticosa”, but the mushroom is also from other Buxus kinds and sorts well-known.
Use only healthy commodity: Suspects or obviously got sick plants reject. The black discolorations of the impulses as well as case of sheet are important notes. Supporting ones chemical measures can construct on the hygiene measures specified here, not replace these however! A fungicide spectrum is tested.
Sheet wetness avoid: Mushroom infections need continuous wetness. After investigations from England are already sufficient five to seven hours of sheet wetness. Wässern only at the soil and early in the morning.
Remove: Gotten sick plants always together with fallen down leaves remove. The highest earth layer should be removed thereby likewise since the exciter in the soil can outlast several years. Remove with the Roden of stricken plants with soil including the heruntergerieselten sheets.
Cut out gotten sick places: This can be successful with fast growing and less susceptible sorts. There however frequently also few cm over the soil at the old wood still infection places (black discolorations at the impulse) to find are, separate the possibility frequently. In addition usually stricken sheets stay in the cut plants, which provide in damp weather for new infections, before the plant regenerated correctly. Since the mushroom at the stricken sheets outlasts, these are to be removed as completely as possible.
Recondition strength strengthen: With existing book tree existence the strength of the plants should be strengthened by good care and regular fertilization. Irrigation of Buchsbaum must take place absolutely from downside, wet leaves is to be avoided.
Disinfection and cleanliness: All used devices and tools as well as shoes and hands must be thoroughly cleaned after use and disinfected after possibility, before further planting are worked on.
