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.

Perilla frutescens, Beefsteak Plant, has become the second worst invasive
plant at the 200 acre Ruth Swann Park in Charles county, MD. Has anyone seen
any patches in trouble by potential biological controls?

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.

So what did nursery stores tell costumers to do when they complained that
their beefsteak plant was having trouble?

I will investigate - Perilla by the way has been for sale in USA since early
19th century (USDA ARS NAL Special Collections - Nursery Catalogs)

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?

Marc
