Poor stands? — Maybe some reasons why

By Harold Watters and Greg LaBarge, Ohio State University Extension The two most common seedling diseases this year were compaction and Pythium. We overworked the soil, this spring and last spring both, and maybe even last fall. Poor soil structure leads to soil compaction and crusting. I often quote Sjoerd Duiker, agronomist at PennState University, this time I’ll just give you his link: https://extension.psu.edu/soil-crusting.  Pythium is another problem our seed treatments only work for so long and this year with cool soils, crusting and excessive rains at the wrong time created a great opportunity for this disease. See Anne Dorrance’s article in a recent C.O.R.N. newsletter for some thoughts on seedling disease: https://agcrops.osu.edu/newsletter/corn-newsletter/2020-17/corn-and-soybean-seedling-blights. I like to give you all some advice with this column, this time I’ll quote a co-worker, “We should have left the seed in the bag until conditions were right.”

After a slow start, weeds are roaring now

By Harold Watters and Greg LaBarge, Ohio State University Extension With the crappy spring we missed proper burndown timing, pre-emergent herbicide application, and now are working on missing the proper timing for post applications. In 2020 we lost the soybean dicamba products after June 30, and now that is permanent with the new labels. In most years and most scenarios we should be done with soybean spraying by July 1, right. The Ohio, Indiana & Illinois Weed Control Guide is a great resource for getting management tips on how best to apply herbicides. See the recommendation tables to choose products for these post applications. The Guide is available from our now reopened county Extension offices, or look for more information on-line from Mark Loux on his Weed Management website: https://u.osu.edu/osuweeds/.
