<P>A message from Dr. Richard L. Boyce:<BR>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).</P>
<P>Once again, I’ve mainly seen the blight on vigorous growth, i.e., on stems
that haven’t yet lignified.</P>
<P>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.</P>

<DIV><SPAN>Since beefsteak plant is in the mint family, I would be looking at
the insects and fungi, especially powdery mildew, which cause problems for
<EM>Monarda</EM> <EM>fistulosa</EM> and <EM>Monarda</EM> <EM>didyma</EM>.
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.</SPAN></DIV>
<DIV><SPAN></SPAN> </DIV>
<DIV><SPAN>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.</SPAN></DIV>

<DIV><SPAN>WALK WITH AN ECOLOGIST<BR>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. <BR> 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. <BR> For people who like showy native flowers there are
beds of <I>Rudbeckia</I> <I>laciniata</I>, <I>Ascelpius</I> <I>syrica</I>,
<I>Verbisina</I> <I>alternifolia</I>, <I>Monarda</I> <I>fistulosa,</I> and
