so -- you may have an infestation of Bagworms! |

Knot of Cherry & Plum
Knots are initially green and soft but then turn brown, harden, and
finally become black as they expand and age. Mature knots eventually
encircle the infected branch and may be several inches to 1 foot (30
cm) or more in length. |

Cluster Fly
They look very similar to house flies but have a fine golden hair
on their thorax. They are earthworm parasites during the summer, but
invade homes during the fall to spend the winter. If they get in they
will be a nuisance all winter long.

Coddling
Moth
The common "worm" found in apples. Pheromone traps can be
used as monitoring tools. Band to trap. (To create substitute location
for the codling moth larvae to spin their cocoons and pupate, band
the tree trunks and large branches by tying 6-inch strips of burlap
or cardboard around them. For central New York, band three times:
May, mid-June, to early July, and August. Timing in other locations
may vary slightly. Check for larvae and cocoons and kill those you
find.) Pick up all drops in late August and September. |
|
Colorado
Potato Beetle
Adult potato beetles are yellow and have ten black longitudinal stripes
on their wing covers, and are about 3/8" in length. The larvae
(or slugs, as they are sometimes called) are brick red in color, hump-backed,
soft bodied and are a bit more than 1/2" in length when full-grown.
They have two rows of black spots on either side of the body. Eggs
are orange-yellow in color and laid in clusters on the underside of
the leaves. |
|
Common
Potato Scab
Potato scab is a common tuber disease that occurs throughout the potato
growing regions of the world. Although scab does not usually affect
total yields, significant economic losses result from reduced marketability
of the tubers. |

Planting
Plants are very active in ways that are not so obvious to the casual
observer. For example, plants change the chemistry of the soil, and
influence the types of microorganisms that grow there. They actively
compete with other plants for space. Some will poison their neighbor's
offspring to maintain a competitive advantage, while others change
the environment in ways that benefit other species. Plants wage a
constant battle with insects, relying heavily on chemical warfare.

Corn
Smut
The plant may be infected at any time in the early stages of its development,
but gradually grows less susceptible after the formation of the ear.
Any part of the plant above the ground can be invaded, although it
is more common on the ears, the tassels, and the nodes than it is
on the leaves, the internodes, and aerial roots. The boil is composed
of a white, smooth covering, enclosing a great mass, sometimes 4 or
5 inches in diameter, of black, greasy, or powdery spores. After the
spores mature, the covering becomes dry and brittle, breaks open,
and permits the black powdery contents to fall out.( |
Common smut, caused by Ustilago maydis, causes infection of most
above ground parts of corn, but is most frequently found on ears.
