The trees are over 10 years old and their fruit has shown these symptoms for the past several years. The owner said he sprayed the trees with insecticide every 10 days after 3/4 petal drop. Is this Cork spot, water core or something else? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13973 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13973 Thu, 17 Sep 2009 04:09:49 CST Hazen variety apple tree has leaves curling on upper 25% of tree. Trees was planted in the fall about 2.5 years ago in the fall and were about 5 ft tall. Soil is 80% clay/20% sandy soil and receives full sun. Tree is watered regularly. Applied Scott's weed-n-feed on lawn but very little around trees. Other apple trees are unaffected. Any idea what is causing leaves to curl? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13969 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13969 Thu, 17 Sep 2009 09:15:28 CST Client purchased Mountain Ash tree 3 years ago and it produced the typical red berries the 1st year. Last year no flowers or berries. This year the white flowers were produced in the spring but now there are not clusters of red berries. Is there a reason why it may not have produced berries and if there ever will be berries again? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13963 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13963 Mon, 14 Sep 2009 03:02:32 CST Client recently began removing large red and jack pines from property. Found both of these wasps since that began. Also found one larger, 2" in length with "tail" an inch longer than the body. Provided info on Ichmeunoid wasp and pigeon tremex horntail but client does not agree. Client is concerned in a Sirex Wood Wasp. Please ID for confirmation and suggest control if necessary. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13938 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13938 Wed, 09 Sep 2009 03:56:27 CST Brown tassle-like growths on balsams. Typically on the end or at a split.

Galls are present and leaves have been dropping all summer. Any ideas on the cause or what needs to be done to save the trees? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13874 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13874 Thu, 20 Aug 2009 12:22:55 CST Client planted a package of shasta daisies in front of kitchen window that gets full sun. This is what came up. Gets about 5-6 feet in height. Please ID. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13867 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13867 Wed, 19 Aug 2009 02:35:33 CST I have received 2 calls about controlling suckers around the base of Canadian Red Cherry (Prunus virginiana, I beleive). Are there herbicide options that won't damage the parent tree? Thank you http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13855 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13855 Tue, 18 Aug 2009 10:45:37 CST 15 yr old maple tree (trunk 10" diameter) losing bark on trunk and limbs; seems to start in the crotches. 1/2 of tree did not leaf out this spring and started on the north side of the tree sometime last year and has steadily worsened. Looks like bark has been chewed away in sections. Suggested animal damage but client disagrees. Same thing is happening in another maple tree 10 feet away. Fir trees and ash tree unaffected. Water the lawn but not trees specifically and lawn care company treats lawn for weeds and applies fertilizer. Found what looks to be an immature western seed conifer bug on sample but found nothing else when peeled away bark. Note: the photos are taken from already dead branches. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13852 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13852 Tue, 18 Aug 2009 09:55:59 CST Asparagus plants are stunted and bushy. Web sites on asparagus problems suggest aphids might be the cause, but I can't find any on the plants. Any ideas? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13729 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13729 Wed, 15 Jul 2009 11:09:31 CST A homeowner has planted Hens & Chicks for years, but this is the first time that he has experienced the tall growth seen in this photo. He is interested in what may be causing this. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13707 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13707 Mon, 13 Jul 2009 01:35:04 CST This is a request from a homeowner to identify the problem with his lawn. Not much additional information beyond the pictures he sent. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13662 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13662 Tue, 30 Jun 2009 02:13:25 CST Three large oak trees have similar symptoms. We already identified mites and aphids on the leaves but there also apears to be skeletonized feeding. There is quite a bit of webbing/fuzz on the leaves and stems where feeding was; however it is not clear in the pictures. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13628 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13628 Fri, 26 Jun 2009 11:29:19 CST Can anyone identify this woody shrub? It is growing near some sumac near a home on an east facing slope and the white flowers have 4 petals. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13600 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13600 Thu, 18 Jun 2009 02:17:39 CST Identification: A homeowner brought this plant in. She stated that it has white flowers. The berries begin as a dark green, turn to deep blue/black and then to white. The plant is about 20 feet tall and was planted 5 years ago. I think it is a dogwood. Any help would be greatly appreciated. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13597 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13597 Tue, 16 Jun 2009 10:32:01 CST Attached is a picture of the plant a client is trying to identify. It's the yellowish spiky looking thing in the middle of the Lily of the Valley. Almost every year she get clumps of these growing in her ferns and shade plants. She's just curious and hasn't had any luck identifying it. Please help. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13590 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13590 Fri, 12 Jun 2009 09:58:30 CST 100 healthy tomato plants were transplanted on Tuesday, June 10th. Two days later nearly all of the plants began to exhibit twisted tops and irregular leaves on the upper part of the plants. Temps in this field have been in the mid-40's at night and low 70's during the day. There has been no herbicide applied in the area in the past week. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13559 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13559 Mon, 08 Jun 2009 02:36:43 CST A landscape maintenance person brought in a maple leaf with multi-colored circular spots about .25 inch in diameter. The middle is brown, then a yellow ring, then a red ring, with the outside ring a dark brownish red. Nothing serious for the tree health, but a curosity. Any ideas? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13539 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13539 Thu, 04 Jun 2009 09:06:07 CST Two samples were found in a food plot. Customer wants to know what they are and if they are benificial to his food plot or if they are just weeds.
