Crops & SeedProper Seed Selection Improves Your ProfitabilityIf the latest genetic enhancements and superior profitability are what you want— then what you need is FS Seed Corn and FS HiSOY® brand soybeans. Recent independent field trials have shown once again no other leading brand outperforms our FS Seed Corn and FS HiSOY hybrids. Even better, when you choose FS Seed you also get the added expertise of your local FS Crop Specialist. He can help you select the hybrid traits that will help you get the most out of every acre. So if you want better performance and better profitability, make the smart choice with FS Seed. Now that’s farming smart. Proven in test after test across the country, WL varieties are delivering more pounds of milk and beef per acre — as well as more tons of hay. To build on the quality and performance in our WL Alfalfa varieties, we have re-launched Roundup Ready® Alfalfa. Key advantages of WL Alfalfa:

Plant Health Fungicide ApplicationsWe have learned a lot about fungicide application in recent years. The first year that fungicide applications occurred on a large scale, there were horror stories from Northern Illinois about ear development issues and barren fields. The root of the problem was the adjuvant in pre-tassel applications. We recommend waiting for the entire field to tassel before spraying. Fungicides can be applied pre-tassel but the adjuvant has to be omitted. In most cases we are better off waiting for tassel emergence even if the corn is uneven. Applications can be delayed until brown silk if disease has not migrated above the ear. Common rust and grey leafspot are the two main diseases that are showing up in fields locally.
The main goal of a fungicide application is to preserve leaf area above the ear to maximize grain fill. Other benefits include improved standability and harvest efficiency. Weed Resistance and Weed ManagementWeed management continues to change over time. One of the most recent of these changes in our area is the shift from conventional to Roundup Ready corn and its growth is due to many of the same reasons that growers moved to Roundup Ready soybeans in the late 1990’s: managing difficult to control weed species, crop safety, and economics. The main concern that farmers with Roundup Ready corn is the fear of weed resistance to Roundup since they are relying heavily on Roundup to control weeds in soybeans in that field the previous year. To get a handle on this issue you really need to have an understanding of how weeds become resistant and what we have learned about resistant weeds from past experience. A common misconception about weed resistance is that weeds become resistant because of reduced herbicide rates and making applications to weeds that are too tall. These are poor management techniques that result in ugly fields, reduced yields, and unhappy farmers but they do not create resistance to a particular herbicide. Weed resistance is due to selection pressure. High selection pressure is the repeated use of one herbicide without breaking its use with other modes of action or management techniques like cultivation. Within any given species of weeds there is diverse population of genetics. All of the velvetleaf in a field may look very similar but from a genetic standpoint they are like people, every plant is slightly different. Weed resistance comes about from a herbicide sorting though billions of weeds and finding the one out of 10 billion that has a slightly different genetic makeup that prevents the herbicide from binding properly or is able to metabolize the herbicide. This single weed survives, goes to seed, and the resistant population grows if the same herbicide is used for primary control. Missouri has three weed species that are resistant to glyphosate (active ingredient in Roundup): common ragweed, tall waterhemp, and horseweed (aka marestail). The resistant tall waterhemp and horseweed were different fields and not surprisingly the field history was very similar; continuous Roundup Ready soybeans since 1996 and uninterrupted use of Roundup for weed control (one or more times per year). This is very similar to triazine resistance (Atrazine, Princep) that occurred in the 1970’s – continuous corn and reliance on atrazine as the base program for weed control. We still have triazine resistant weeds in our area, the main one being tall waterhemp, but it is not a major problem because it is getting controlled other herbicides. Your entire farm is Roundup corn and Roundup soybeans, what should your weed control program look like? It needs to start with residual herbicides applied preplant or preemergence and use Roundup for the post cleanup. Residual herbicides reduce weed densities with different mode of action and significantly reduce the selection pressure on Roundup. There are a lot of good options for residual herbicides in soybeans and the decision needs to be based the field history and what weeds have been a problem. Residual herbicides need to be on every acre ahead of Roundup Ready Corn not only for protecting yield from early season weed competition but also for reducing selection pressure on Roundup. Premixes like Harness Xtra and Lexar work best since they use more than one mode of action. Atrazine alone lacks grass activity and will not control triazine resistant weeds.
Right now there are growers that are using Roundup as a burndown, and 2 passes of Roundup post in soybeans. The following year on the same acre they will apply 2 passes of Roundup post in their Roundup Ready corn. This is a recipe for disaster. Roundup resistant weeds are growing in numbers because of poor management. Roundup soybeans followed by Roundup corn will be sustainable if it is managed properly with residual herbicides and tank mixing products like 2,4-D for burndown.
