[MAIPC] [INVASIVES] WALK WITH AN ECOLOGIST

Thu Sep 5 05:06:24 PDT 2013

Earlier this summer I tagged several plants and agree that the non-native honeysuckles are being heavily knocked back in northern Berks County, PA.  I am not sure if I agree with your assessment of the lignified versus non-lignified tissues and vigorous versus non-vigorous growth as the leaves on many pants are simply dying.  I am seeing witches broom on many bush honeysuckles.  Chlorosis seems to be prevalent throughout.  Leaf shape on infected plants appears to change, making plant identification somewhat confusing. At least on Lonicera japonica, many plants appear to have notched leaves on the outer margins that appears to be herbivory.  Simultaneously with the notching is chlorosis.  

If you go to my FB Biocontrol page, https://www.facebook.com/pages/Biocontrol/478613962188654, you will see photos of what I am doing tracking Lonicera maacki, Lonicera morrowii, Lonicera japonica, Perilla frutescens, Ailanthus altissima, Rosa multiflora and others.  One interesting observation is that when I see a heavily diseased woody non-native, I also see the other woody non-natives in contact with it or in close proximity showing the same symptoms.  This is probably related to the ecosystems of origin for these plants being the same or very close together.

One exciting observation is that Ailanthus altissima plants that last summer were heavily infested with Atteva aurea are this year showing chlorosis and dieback.  I am not convinced yet that the dieback is caused by Atteva aurea as the trees are located in a flood plain. and the dieback may be due to other factors.  Mostly this year, I am seeing more Aculops ailanthii than Atteva aurea.  This may change as the season progresses as this has been a very late summer.

As I get time, I will post more photos on FB and write a more thorough account of my observations.

If anyone is in my area and wants to spend a couple hours with me walking along Blue Marsh, it will be appreciated as another perspective is always very good to ensure that my observations are correct.

>A message from Dr. Richard L. Boyce:
>As I noted last year about this time, 
this year I’m again seeing a lot of honeysuckle leaf blight on Amur honeysuckle 
(Lonicera maackii) in the Cincinnati area. One additional wrinkle is that I’m 
now seeing it in an area where I’ve also found a lot of dead honeysuckle. This 
is an area called Woodland Mound Park, just east of Cincinnati, where I’ve been 
working since 2005. I did not collect data there last year, so I don’t know if 
the leaf blight led to these particular honeysuckles dying, but let’s just say 
that circumstantial evidence is high, since there was a lot of blight all over 
the area last year. This is also the first time I’ve seen enough dead 
honeysuckles to notice (mainly medium-sized bushes a few feet high). 
>Once again, I’ve mainly seen the blight on vigorous growth, i.e., on stems 
that haven’t yet lignified. 
>I would ask you to again report any sightings of leaf blight you see on any 
honeysuckle species. I’ve included a couple of pictures that may help. I spent 
the last two weeks in in New England, where I mainly saw Tatarian and Japanese 
honeysuckle, and I didn’t notice any leaf blight there.

>Since beefsteak plant is in the mint family, I would be looking at 
the insects and fungi, especially powdery mildew, which cause problems for Monarda fistulosa and Monarda didyma.  
Powdery mildew did extensive damage to my bee balms this summer.  I will be 
posting to my Biocontrol FB page later this week photos from Woodmont NRMA, near 
Hancock, MD which I took today showing beefsteak plant with potential 
issues. 
>  
>The other possibilities is that since it has a wonderful fragrance is 
to harvest and dry it commercially for tea or harvest it fresh and add it to 
vodka, bourbon or rum for a wonderful sugar-free version of a mint 
julep.

>>WALK WITH AN ECOLOGIST
>>On Saturday, October 5 in Berks County, 
  PA meet on North Heidelberg Road at the trail head next to Rt. 183, near 
  Bernville at 9:00 a.m. . Then walk south along Rt. 183 to view ongoing 
  research into various invasive plants that are being eradicated by native 
  organisms and plants that are not yet in the process. At the same time we will 
  discuss the theory and practice to enhance this process. From there we will 
  loop trail to Sheidy Road to view a mile-a-minute bed of several acres. Then 
  we will head back to the cars at the start. 
>> Total distance will be @ 
  7 miles with a long easy stretch at the beginning and moderate climbs in the 
  second half. There is a 3 mile out and back option of flat trail for those who 
  are interested. 
>> For people who like showy native flowers there are 
  beds of Rudbeckia laciniata, Ascelpius syrica, Verbisina alternifolia, Monarda fistulosa, and  various Solidago sp.. Some of these should be full of butterflies and  moths.

>>Hi john  Peter, 
>>  
>>Perilla frutescens has become the  second worst invasive plant at the 200 acre Ruth B. Swann Park in Charles  County. Other folks are finding the sme problem. Any status on biologival  controls? What did gardeners who planted it years ago have to protect it  from?
