Earwig
It Is Earwig Time!
During late May and early June half grown earwigs emerge
from the ground and begin to feed on plants. In general they prefer damp
weather, but the heavy rains of the past 10 days could help reduce problems.
Look for feeding on flowers and leaves. They seem to prefer marigolds,
but damage can be found on almost any plant. You must treat the mulch
area with granular insecticides or drench mulch with a moderate volume
of liquid material.
Ash Decline
Ash Decline
We have been getting a number of calls on ash that have
been late in leafing out or having sections that have not broken buds
yet. There can be many causes and the first thought is that the dry summers
of the past two years has caused dieback. It is best to give the trees
some time as past history has shown use that many of these trees will
look fine by early July. Other causes of decline include verticillim wilt,
see XHT1008 at http://www.plantpath.wisc.edu/pddc/pddcgraphics/Publications/WoodyLC.htm,
and a number of insects, see http:///www.entomology.wisc.edu/emeraldashborer.
Spittle Bug Damage
Spittle Bugs
Those frothy masses have small spittlebug nymphs inside.
The insect hides inside the bubbled up plant sap. Damage is minor but
can include curled or distorted growth. They have only one generation
per year and will transform into adults and no longer cause the spittle
masses or damage by late June. You can hand destroy the nymphs. If you
decide to spray, make sure you use enough pressure to get the material
into the mass.
