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 righ ....
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/. ....
By Alex Lindsey and Greg LaBarge, Adapted from C.O.R.N. 13-2021 When we examine crop emergence post-planting, two factors can impact speed of emergence soil moisture content and soil temperatures. If soil temperatures are lower, it can take more calendar days for emergence to occur meaning rowing corn may take a little more time. In the Ohio Agronomy Guide, emergence should begin to occur after approximately 100 air GDDs. A difference in 10 degrees in temperature can dramatically affect how quickly crops will emerge. For example, at a temperature of 60 degrees F heat unit accumulation per day would be 60 F – 50 (base temperature for growth) = 10 GDDs. If it takes 100 GDDs to start to see emergence, at this rate it would take 10 calendar days to see the crop start to emerge. If temperatures are 70 degrees F, heat unit accumulation per day would be 70 F – 50 = 20 GDDs. This would shorten the emergence window to 5 calendar days instead, resulting in more rapid emergence ....
