*         Alphitomorpha communis

*         Erysiphe communis

Erysiphe cruciferarum is a  <https://en.wikipedia.org/wiki/Plant_pathology>
plant pathogen of the family  <https://en.wikipedia.org/wiki/Erysiphaceae>
Erysiphaceae, which causes the main
<https://en.wikipedia.org/wiki/Powdery_mildew> powdery mildew of crucifers,
including on  <https://en.wikipedia.org/wiki/Brassica> Brassica crops, such
as cauliflower, cabbage, broccoli, and
<https://en.wikipedia.org/wiki/Brussels_sprouts> Brussels sprouts.
<https://en.wikipedia.org/wiki/Erysiphe_cruciferarum#cite_note-1> [1] E.
cruciferarum is distributed worldwide, and is of particular concentration in
continental Europe and the Indian subcontinent.
<https://en.wikipedia.org/wiki/Erysiphe_cruciferarum#cite_note-2> [2] E.
cruciferarum is an  <https://en.wikipedia.org/wiki/Ascomycota> ascomycete
fungus that has both sexual and asexual stages. It is also an
<https://en.wikipedia.org/wiki/Obligate_parasite> obligate parasite that
appears to have host specificity; for example, isolates from turnip will not
infect Brussels sprout, and vice versa.
<https://en.wikipedia.org/wiki/Erysiphe_cruciferarum#cite_note-:0-3> [3]
While being a part of the family Erysiphaceae, it belongs to those members
in which the conidia are formed singly and whose haustoria are multilobed.
<https://en.wikipedia.org/wiki/Erysiphe_cruciferarum#cite_note-4> [4]

This species is also being evaluated as a potential

the invasive plant  <https://en.wikipedia.org/wiki/Garlic_mustard> garlic
mustard.

So how fast is powdery mildew Erysiphe cruciferarum moving around in
Maryland? Who can move it around? How host specific and native is it of
course? Marc

Hi,

Our botanist found this article about powdery mildew:

https://pubmed.ncbi.nlm.nih.gov/21636376/

 

 

It sounds like it may be impacting growth of the invasive. Yay!

 

I will share with our team the information about posting on Eddmaps when
seeing the garlic mustard aphids.

 

Thank you,

 

Patricia

Thanks all!   I just entered this in EDDMaps - and alerted my volunteers as
well.

You are probably seeing garlic mustard aphids (Lipaphis alliarae). Holden

observation efforts. Contact Becah Troutman at rtroutman at holdenfg.org

Nope but I've seen Garlic Mustard with LOTS of little grey bugs on it -
especially on the tips and siliques - and been meaning to ask if others have
seen this!

Hi,

Has anyone been seeing this mildew on garlic mustard? See attached photo.
Any knowledge of a biocontrol like this?

 

Thank you,
