The Corteva Agriscience research and development engine is powering delivery of more Enlist E3® soybean varieties, resulting in new germplasm, many with unique Corteva genetics and advanced performance with improved agronomic packages. Starting with the 2023 season, AgVenture has access to more options than ever before to match the best varieties to our customers’ fields.
Many farmers have utilized Enlist® herbicides with Colex-D® technology on their Enlist E3® soybean and PhytoGen® Enlist® cotton acres this season, and industry demand for Enlist E3 soybeans continues to grow. Some questions have been raised about leaf malformation (often referred to as “leaf cupping”) on Enlist E3 soybeans in some fields. This advisory statement reviews the testing record for the Enlist E3 soybean trait and provides resources for help in identifying symptomology that may be seen on Enlist E3 soybeans, soybeans from other trait platforms or conventional soybeans.
The status of corn is an interesting one even after most have caught some rain. The wind and/or hail issues that ran through several states left corn beat up and laid down. Across Missouri, Iowa, and Illinois, it is tasseling or will be within the next week or two. Corn is very short with shorter than normal internodes.
Tissue testing is a great way to manage your nutrient levels in-season and can help boost your yields. However, it must be done correctly to see a gain in your fields this fall. As tissue testing detects whether your plant has sufficient nutrients for growth, knowing when and what to test is imperative. Keep in mind, that tissue testing should not be the only way you determine management strategies for your crops.
So you finally got, or are about to get, some rain. Whew! Good news after a tough 6-8 weeks here in the Midwest. What now?
Northern corn leaf blight is an annual threat in cornfields from the Midwest to the Atlantic Coast, wherever environmental conditions are met. It spreads quickly from south to north, riding hurricane winds to infect new areas.
You’ve no doubt heard a lot of talk about instances of widespread injury to non-dicamba-tolerant soybeans. Many farmers have reported fields with distinct dicamba symptomology, uniformly visible across fields. Weed scientists and university extensions have been investigating this issue and looking for possible explanations for what is causing in-crop dicamba to apparently move beyond labeled buffer zones. These experts believe that, under certain conditions, volatilized dicamba is likely becoming “trapped” in the air, where it can then move to distant fields.
Soybean white mold is an annual threat in the northern United States (north of Interstate 70) from Nebraska to the Atlantic Coast, though it may appear anywhere when conditions are right.
Timely, preventive action is necessary to maximize yield in the presence of white mold. Geographic location is only one piece of the puzzle. Also consider spring climate, planting practices, soybean variety, microclimate and field history when weighing the potential of white mold development.
Tar spot is a foliar disease of corn that has recently emerged as an economic concern for corn production in the Midwestern U.S. It is not a new disease, having been first identified in 1904 in high valleys in Mexico. Historically, tar spot’s range was limited to high elevations in cool, humid areas in Latin America, but it has now spread to South American tropics and parts of North America. It first appeared in the U.S. in 2015.
