The area of the garden where the cauliflower plants are growing is mulched with soybean straw. The soybean straw has numerous mushrooms growing in it. The grower wants to know if soybean straw contributed to the cauliflower root rot AND, now that the caulflower plants are already infected with some type of a root rot, is there any treatment that could be applied to the cauliflower to save it. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=8350 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=8350 Fri, 18 Jul 2008 12:00:00 CST The tomatoes are grown in containers. He uses a five gallon bucket with soil inside of a six gallon bucket that stores water. Last year his crops were very productive and the first part of this year were great as well. Now his crop is infected with this disease he would like any suggestions of treatment if not to save this crop to prevent it in the future. The only thing he has used on his plants is an organic compound called millstop which is like 80% potassium. Thanks http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=7930 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=7930 Thu, 12 Jun 2008 12:00:00 CST Would you agree that this is Head Scab? This field was treated with Headline to control Powdery Mildew. Headline is not labled for Scab but I think that Proline is. Is there any value in treating fields with Proline if they are not showing Scab sysmptoms http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=7831 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=7831 Thu, 05 Jun 2008 12:00:00 CST This Cherry tree is from the same client as the apple tree. Last year they started to notice "cankers" on the trunk. This year the tree lost most leaves about 10-14 days ago. There was 1 nest and a few eastern tent catepillars still on the tree and a pretty good frost ~2 weeks ago. Thank you, Randy http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=7311 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=7311 Tue, 24 Jul 2007 12:00:00 CST A portion of the field is showing these disease like symotoms. Any ideas? Thanks http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=7312 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=7312 Tue, 24 Jul 2007 12:00:00 CST Another soybean leaf disease symptom. Any ideas? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=7191 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=7191 Thu, 28 Jun 2007 12:00:00 CST Grower is not happy with the weed control, especially Foxtail control with Steadfast treatment. Tank mixed with Dicamba for broadleaf weeds. While many foxtail are stunted many are not and not dieing back. Applciation made about two weeks again when grasses were less than two inches tall. Ideas for poor performance?

The symptoms are showing up in small areas--a couple of rows wide by 20-30 feet long, one at the edge of the field and the other more centrally located. The patches are spreading. Field is relatively low, flat ground that was subject to less drought stress than most this year. These areas are not noticably different in any way. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=4110 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=4110 Thu, 12 May 2005 12:00:00 CST This is only a test of a Digital Blue Microsope and the 10x image of a leaf surface. If Craig Grau, Brian Hudelson, or any other UWEX Specialist or Agent has an opinion of the quality of the image or the application of this technology, feel free to comment http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=4130 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=4130 Thu, 12 May 2005 12:00:00 CST Digital Blue Microscope Test 2 How are the images at 10, 60 and 200x of the weed leaf surface? Could one possibly determine some disease infections? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=4051 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=4051 Sun, 26 Sep 2004 12:00:00 CST A producer brought this sample into the office. He said it was covering the top and sides of his corn bin. It appears to be some type of mold, but looks and feels similar to a silky-like nylon web. I did detect some dead insects in some of the grain. Any idea what type of moold this might be? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=3872 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=3872 Wed, 30 Jun 2004 12:00:00 CST Wheat scab has really exploded during the past week in East Central WI. This particular field had 80 percent head infection and a whopping 40 to 45 percent total spikelet infection (Ohio State calls 10 percent spikelet infection an "epidemic"). This particular farm had one field no-till after corn silage, one was no-till after corn for grain (planted late), one field no-till after soybeans, and one field no-till after wheat. None were good, but the one following soybeans was the best and the one following corn silage was the worse. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=3873 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=3873 Wed, 30 Jun 2004 12:00:00 CST Soybean leaf disease (Bacterial pustule) appears common. In this case I was interested by the difference in variety apparent in a "strip trial". Color contrast was dramatic. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=3850 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=3850 Mon, 28 Jun 2004 12:00:00 CST Round up Ready beans planted in hay/sod are exhibiting wilting and dying of upper plant, almost looks like frost injury, but is not (too patchy and not consistant with frost injury). I have looked at several fields from several different producers and I am seeing similar injury. Some plants are dead, others are starting to regrow from basal buds. Most fields were planted 4-5 weeks ago. With either a spring or fall burn down and a RR application in the last week or two. Symptoms are spot to very wide spread. There is also spotchy rust like pots on the leaves, like a bacterial blight. I did find it interesting that one field that has not been sprayed with RR did not have the wilting syptoms as the others, only the rust pots. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=3450 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=3450 Thu, 10 Jul 2003 12:00:00 CST A 4-yr old alfalfa stand with a significant amount of Verticillium wilt. Pictures depict plants in various stages. Recommendation #3 in the Alfalfa Mangement Guide seems a little contradictory. It states to harvest non-infested fields first (to avoid spread between fields) AND to harvest infested fields early to limit yield/quality losses and slow spread within the field. My thinking would be to harvest this field first, clean cutting equipment, then move on. Thoughts? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=2630 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=2630 Tue, 04 Jun 2002 12:00:00 CST Septoria and powdery mildew on winter wheat.Current wheat outlook suggests $2.30/b for fall delivery. Economics may not favor spraying Tilt plus the custom application rate is running over $15/a. Information from Craig Grau. Manitowoc County photos, 6/02. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=2270 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=2270 Mon, 22 Oct 2001 12:00:00 CST Several reports of moldy corn this fall (probably more that are not being noticed or reported). This field appeared to to have considerable bird damage. Both white (Fusarium) and green molds (I'm guessing Penicillium)are apparent and, in some cases, lots of it. Also, kernel sprouting evident. Some of this field had been chopped earlier for silage but condition was unknown at that time. About 10 acres remains. Given the condition of the corn (see photos), shelling for high moisture is not a good option. What about shelling and drying, then off to market? This field was was planted relatively early (early May). http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=1989 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=1989 Fri, 24 Aug 2001 12:00:00 CST Symptoms appear to match description for bacterial pustule (small, pale green spots with brown centers; occurs in wet weather from flowering to early pod formation). This particular field,however,is closer to R6 (full seed). Some rain and humidity last 10-14 days but very dry prior to that. Positive ID appreciated.

Submission from Reedsville Coop. RR beans sprayed about a month ago. Moisture stressed for some time. No obvious bacterial type lesions on leaves. Root health appears normal.In last 2-3 weeks, general leaf discoloration followed by leaf drop and plant death has been noted.One of 4 photos notes second variety in background that was totally unaffected. Eight weeks of dry weather has compounded this problem. Please advise. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=1489 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=1489 Wed, 25 Jul 2001 12:00:00 CST Found in several areas in the field. RR beans. Was sprayed for aphids recently. Possibly some tank mix herbicide contamination. Field was clean a week ago. Pattern, however, does not match completely with the boom pattern. Soybean virus?

The rest is close.Septoria leaf blotch is showing up on lower leaves. Flag leaves are still clean for the most part. Too late for Tilt applications or not? Manitowoc County photo, 6/1/01. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=365 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=365 Wed, 16 Aug 2000 12:00:00 CST Prevalent in much of the early planted corn. Positive ID appreciated. Would expect that this will hasten whole plant dry down for silage. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=359 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=359 Mon, 07 Aug 2000 12:00:00 CST Apothecia in Garst D180 drilled soybeans on August 7,2000. Any correlation between number of sclerotia and severity of white mold to expect? This may the research that is currently underway. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=342 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=342 Fri, 14 Jul 2000 12:00:00 CST Beans are close to R1. Numerous plants show leaf distortion as noted. Reviewed the American Soybean Association Diagnostic Guide. Viruses are suggested. Comments appreciated. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=333 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=333 Tue, 27 Jun 2000 12:00:00 CST Given saturated soil conditions in recent weeks, soybean seedling mortality is showing up. Not sure whether this is Rhizoctonia, Fusarium or Phytopthora. Plant decay is pretty far along to find the brown lesions on the stem above the soil line that would key phytopthora. Its a Dairyland variety with some resistance to PRR so it may well be Fusarium or Rhizoctonia. Comments on how to properly ID would help. Also, there seems to be a reluctance on the part of the coop. to use Apron XL and Maxim. Is there a compatibility problem with most inoculums on the market and this fungicide combination?
