Pulling the husks back reveil a few kernels at most per ear. An occasional plant (5% of total) have near normal developed ears. The majority of the area will not produce any yield. This is a corn field following several years of soybeans. I was told by the seed rep that Aim was used as a burndown with soybeans the year before followed by Roundup. Lumax was apparently applied to corn this spring at 2nd leaf stage. Planted May 5th, and a 98 day maturity variety with several trait stacks. Noticed the soil in this area of the field to be wetter than the rest of the field. I took a video with much greater detail of what the field looks like but will need to find a method to get on-line. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=14040 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=14040 Tue, 10 Nov 2009 12:58:03 CST New homeowner reported the issue, so there is not a lot of history to go by. Bark has been sloughing off and branches dying. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=14025 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=14025 Mon, 19 Oct 2009 03:28:53 CST This plant was found in woodland, 45% canopy along the forest trail road. Any suggestions as to it's identification? Thanks http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=14019 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=14019 Mon, 12 Oct 2009 01:55:10 CST Homeowner has 10-15 arbor vitae with branch dieback in just a few specimens. They were planted about 15 years ago. Landowner noticed sap running when she trimmed back the dieing branches. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=14012 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=14012 Tue, 06 Oct 2009 04:06:19 CST These Cortland and Paula Red apples both exhibit brown spots in the fruit. 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=14005 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=14005 Thu, 01 Oct 2009 12:19:40 CST Found growing along asphalt driveway at the edge of where red granite fill meets the lawn. When first picked (two weeks ago) outside was beige in color and inside dark brown and mushy. Now inside is the color of baking cocoa and a powder. Any ideas of what kind it is? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13998 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13998 Wed, 23 Sep 2009 11:11:42 CST The symptoms shown in the pictures are showing up in various situations in Marinette & Oconto Counties this year. Most severe symptoms are on corn on corn on the drier soils. The pictured plants are from a field of Garst hybrids, in which about 60% of the plants exhibit some degree of these symptoms. Only areas without symptoms are on moister soils. I know that there are fungal leaf spot issues, but am mostly concerned about the interveinal chlorosis and what may be interacting to cause that. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13990 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13990 Tue, 22 Sep 2009 09:20:43 CST Plant is growing on top of soil in one of two raised vegetable garden beds 4"x20' and has been an ongoing issue for 3 years. Extremely shallow rooted. Live in heavily wooded area and gardens receive only morning sun. Rotates vegetables on a yearly basis. Uses no lime, pesticides or herbicides but uses Miracle Gro and fertilizes w/dead fish and algae from pond. Doesn't seem to affect vegetable grow or production. Is afraid is taking nutrients away from produce. Please ID and suggest control. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13982 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13982 Mon, 21 Sep 2009 02:44:57 CST Anyone have resources to answer mushroom ID questions? Can anyone give me a name or family that this mushroom belongs to? Homeowner is curious as to what it is and how it reproduces. Thanks! 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=13970 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13970 Thu, 17 Sep 2009 09:22:39 CST Homeowner found this plant in her garden. Hummingbirds love it. Wants to know if it is an invasive, or can she share seeds of it with her neighbors 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=13957 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13957 Mon, 14 Sep 2009 02:30:34 CST A positive ID would be much appreciated! To me this weed looks like a nightshade composite with a little white cockle for good measure. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13947 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13947 Fri, 11 Sep 2009 01:53:43 CST Conventional soybean planted into corn about mid-May. Outlook and First Rate applied pre-emergence. Many lambsquarters escaped control. About 1/4 of field looks like these samples. Many aphid skins. No visible sign of BSR. Japanese beetle feeding on some leaves. Problem a result of combination of poor weed control, dry weather, and an aphid outbreak? 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. Please ID problem. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13932 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13932 Wed, 09 Sep 2009 03:15:14 CST Client has small balsam trees affected. Believe it to be midge. Looking for confirmation and control if necessary. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13930 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13930 Wed, 09 Sep 2009 08:58:06 CST This plant was found growing in a neglected perennial garden that the new owner wants to renovate. Is this a perennial that should be saved or is it a weed? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13927 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13927 Tue, 08 Sep 2009 11:20:24 CST This plant is growing wild in homeowners wooded area behind his house. He's very interested to find out what it might be. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13922 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13922 Thu, 03 Sep 2009 08:45:40 CST Five hickory trees (one mature and four young trees) have been showing signs of decline for several years. 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=13914 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13914 Wed, 02 Sep 2009 01:09:20 CST Client received a deck planter early this spring as a gift. This began growing out of it and is now 7ft tall with a 2" diameter stalk. Side shoots have the top tassel which looks like it will have tiny small yellow flowers once it actually blooms. Leaves have stiff hairs and almost feel sandpaperish on both sides with rough woody stalks. Looking for an ID. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13912 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13912 Tue, 01 Sep 2009 03:28:57 CST Lady working in her yard was bitten by this bug. Well developed first set of legs, my guess is a predatory insect. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13907 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13907 Tue, 01 Sep 2009 01:28:45 CST It continues to amaze how fast wild parsnip is spreading. This town road was mowed after the initial flush of WP was headed out (about 2 weeks earlier than the county roads, and the 2nd mowing of the season). Now we see a second strong flush coming-on. Can we really expect road crews to mow for a 3rd time? That will be a tough sell (I think). Interestingly, the county roads mowed 2 weeks later have no regrowth, but the seed from the first flush may have been viable (not sure). Do we know the best mowing strategy? Maybe there isn't one as evidenced by the last picture of WP near the culvert in my front lawn. I "weed whack" that area pretty regularly. I think we might be fighting a losing battle unless mowing occurs frequently (not likely) or a chemical approach is initiated (also not likely). http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13891 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13891 Tue, 25 Aug 2009 08:16:46 CST Beetles found inside kitchen cupboards, 3/16" long. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13886 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13886 Thu, 20 Aug 2009 04:41:45 CST Homeowner has numerous brown patches scattered throughout his lawn. Pictures in turfgrass compendium point towrd some type of fungal issue.
