Sphaeropsis or Diplodia Tipblight- Austrian & Scotch Pines

This is the disease that makes the tips of needles of these pine trees turn brown in the late spring and early summer. The disease starts on the lower branches and then works upward. With time, and the disease out of control, the tree or trees will look so terrible most owners cut them down as they become an eyesore. Also, please note the top picture, as you can see how the disease starts on one tree then spreads to other nearby trees. If you do not stop the disease with a funcicide spray, it will continue to the adjoining tree or trees and it will consume all the trees in the group.

However, this disease is controllable with timely fungicide sprays and the removal of the brown tips and also removing of the old needles and old pine cones on the ground under the tree. The brown needle tips and the old needles and cones under the tree contain fungus spores which reinfect the tree. When these items are removed there is less of a chance of infection. I have many customers that "police" their trees as to the removal and "cleanup" of the brown tips and old needles and pine cones. They do have a high rate of "success" in saving their trees with this cleanup operation.!

All of my customers that have this disease on their trees get my "instruction sheet" on how to control this disease based on information provided from the University of Illinois at Champaign.

This control program works, but it takes energy on your part to accomplish this disease control. Usually, trees have both Sphaeropsis and Zimmerman Borers at the same time. Fungicide sprays are very effective in the early spring and summer.

Austrian & Scotch Pine Insect Problems-Zimmerman Borers

Chicagoland Insect Warning April 18, 2006

The University of Illinois is warning that insects that bore in trees are going to be very active due to the drought conditions that now prevail. Drought stricken trees (Austrian & Scotch Pines) will receive much more damage this 2006 season, as wood-boring insects such as Zimmerman Pine Moth larvae will find it much easier to bore into these trees. Stressed trees also give of chemical clues to insects that bore into them and then these insects are more aware as to which trees are in trouble so they really can pin-point their attack. Water deficient trees also have a reduction of defense chemicals, due to the lack of moisture within the cells of the trees thus making them a much better target for these "tree wrecking" insects.

The bottom line of these drought stressed Austrian and Scotch pines is that these trees will harbor many-many more of the usual population of these insects. This will result in much more "internal boring damage" to your trees this season. This boring damage is not repairable.

My disease and insect programs are sound, proven methods of control and most important, I use only proven insecticides and fungicides that are effective on these troublesome trees.


Above, is a photo for you to look at and then go out to your trees and check for the "white masses" as shown on my photo. You will not see any insects or larvae as they are very small and very hard to locate. The "white masses" denotes the active presence of Zimmerman Pine Moths. Inspect your tree or trees from top to bottom for these easy to find "white masses".

These insects are Zimmerman Pine Moth Borers and they can be controlled in April and early May 2006 with "a unique NEW " insecticide that is used to "soak" the bark of the trees to get where these borers hide and hibernate and also the spraying of the insecticide will "nail" them when they are crawling around in the tree in the spring

The damage created by "Zimmerman Borers" are internal borings which destroys and weakens the branches and trunk. In the upper right photo the borers have weakened the trunk to an extent that it has snapped off. Their favorite place to work is about 3 to 4 feet down from the top of the tree where they bore deeply into the trunk so bad that the trunk breaks off as shown in the above photo. You will lose the whole top of the tree when this happens! These are troublesome trees but they are salvageable through the use of insecticides and fungicides.

Timing of insecticide sprays are critical, as these insects are more active when the weather is warm. The tend to hide under bark scales of the tree when the temperatures get lower, making them an elusive target.

Please call me at 630-759-3035 and I will be right out to save your trees and remember, all that you need at this point in time is one insecticide spray.

Saved River Birch on Culpepper Drive. Naperville, IL

Yes, saved from becoming firewood!

This very large River Birch tree right in back of the garage did not have any iron injections for 5 years, as the new owners were unaware that the tree needed iron to survive. This tree had all yellow leaves that were also very small. It was very-very sick.

Additionally this tree had a very useful life, as it provided shade to the house and deck in the morning sunlight. Losing a large tree like this one would drastically reduce the value of this property.
In Naperville, people buy trees with houses!

I injected this River Birch with my special iron on June 2, 2005 with 3 following small injections spaced apart by 1 day. It's called tender and loving tree care!

Today, this tree is having a very nice life providing shade to the house and deck.
Plus, its healthy existence is making this home a more valuable piece of property.

Gettysburg Ct. Pin Oak-- Naperville, IL

On The Immediate Left, This Pin Oak Had An Iron and Manganese Injection On August 1, 2005 Under Severe Drought-Actually Dust Bowl Conditions!---Watch The Progress!

The Photo On The Top Left Was Taken On August 31, 2005 --30 Days After The First Injection...The Tree Has Turned Green and Please Notice It Has Got Much More Dense As My Special Iron /Manganese Formula Works Its Wonders!!!-All This Without Any Watering Of The Tree!!--- Another "Saved" Pin Oak In Naperville.

Your Tree Can Be Treated and Saved Even If It's A River Birch or a White Oak!

On The Right, Note The Plastic Tubes Being Used to Inject Iron & Manganese Into The Tree. They Are Handmade By Me and They Only Require An Injection Hole of 5/16 Inches Which Is Less Than 1/2 Of the Diameter Of A Pencil---- VERY UNIQUE !
