Michigan’s soybean rust sentinel plot scouting report: August 4–11 Sandy Perry, SBR Sentinel Plot Coordinator |
No soybean rust has been found on soybeans or other plants in Michigan or anywhere in the region, including Ontario, Canada. The following is a compilation of the scouting reports Growth stage: Three plots are at R4 and seven plots are at R5. Plant height: Two plots ranged from 20 to 30 inches, and eight plots ranged between 36 and 48 inches. Degree of canopy closure: All plots ranged between 95 and 100 percent closure. Soybean diseases present: Downy mildew is present in half the plots at low to moderate levels but the incidence is increasing. Brown spot remains at low levels in three plots. Insects present: Two plots have recently been sprayed for soybean aphids, three plots have per plant populations of soybean aphids ranging from 250 to 420 with honeydew and sooty mold present, two plots have low incidence of soybean aphids and three plots report no soybean aphids. Spider mite damage was noted on 5 to 10 percent of the leaves in one plot. There is no MSU Diagnostic Services report this week. National soybean rust update New reports of soybean rust in the Deep South are coming in almost daily. However, the disease does not seem to be spreading very far very fast considering the weather has been ideal for infection. The majority of findings are along or near the Gulf Coast in Florida, Alabama and Mississippi. Two counties in southern Georgia (bordering Florida) have reported infections. Within the last week, rust was discovered in two counties in mid-state Georgia and two counties in mid-state Alabama, which are now the most northerly confirmed infections.

Try our new search engine Joy N. Landis, MSU IPM Program |
We recently added a Google search to the New Agriculture Network web site. Try it out by clicking on the search link on the site’s navigational bar. You can enter any keyword or topic or author’s name. Some examples of potential searches would be: thistle, or flamers, or oilseed radish. Our search engine is provided free through collaboration with Google. The trade-off is that sponsored links also appear on the page that may not be of interest to you. Most searches will result in a list with links from the New Ag Network along the left and sponsored links along the right. A few searches that I’ve tested result in sponsored links also added to the top of the results. See the accompanying example where “Agricultural Crop Covers” appears at the top of the list and you must look to the right to see that it is a sponsored link. The rest of the links below “Agricultural Crop Covers” are New Ag Network articles related to cover crops. These sponsored links are web sites that have paid to have their site appear. We hope the addition of this search engine will help readers more quickly locate information published by the New Ag Network. Feel free to send comments to newagnet@msu.edu. |

Michigan Indiana At mid-summer we are already thinking and living fall. We know the rest of summer will go quick. We are planning things like when to pull tomatoes from the greenhouse to plant salad greens for fall, and asking questions about what are we going to put under row covers and what we’ll leave exposed, etc. We are currently harvesting salad greens, tomatoes, curly kale, less lacinato kale, parsley and dandelion greens. We have finished planting and have germinated our long season fall plantings—the brassicas, more kale, chard etc. We are continuing to keep up with weekly salad greens plantings. I am actually having some time to spend on farm maintenance and repairs. We just did our yearly certification inspection. The problems we had with marketing at one distributor have been cleared up. It took having to say a word to the overall produce manager, who incidentally is going to be doing the ordering for both of this store’s outlets to correct the problems and set up sane systems. The kid we were having problems with I’m sure got his feelings hurt, but he’ll get over it. We did it all right with tact, etc. We just harvested the second variety of Asian pears. These are mostly for home use but there are several bushels for sale. Fruit set was light this year and there are only 10 trees of this variety. An interesting side note on the A. pears is that after fruit set in the spring the trees received a light frost. This frost ‘cracked’ the small fruitlets, then about the size of a fingernail. I thought that would do them in, but the cracks healed. The round A. pears look like a pealed orange or some sort of segmented fruit where the frost cracks did not grow at the same rate as the rest of the fruit but have not harmed the fruit quality. Another oddity of this year is that stink bug is not yet getting into the A. pears, whereas in past years their damage could ruin a harvest. I suspect it is the lack of dry, hot conditions and I am keeping my eye on the fruit still hanging in other trees. In the next two weeks we’ll keep up on salad greens planting, do heavy weeding on the fall crops that have been planted and germinated, finish up some mowing, continue with some farm maintenance before fall overwhelms us to spit us out into winter, and will probably do some more herbicide trials. Question We are still trying to figure out growing Swiss chard disease-free in the hotter months. Our last experiment was to mow it all back and do regular copper hydroxide sprays. This seemed to help some compared to areas we did not treat, but still it did not control black spot enough for a harvest. Illinois East Central Illinois – Jon Cherniss Central Illinois – Dave Bishop Question: How is everyone else coping with the dry, hot weather? Southern Illinois – Stan Schutte Iowa I still have straw to bale and flax to deliver. In the next two weeks I have liquid manure to haul and a little disking to do on the triticale field where there is no cover crop. |
