Even the most superior products do not win every plot. When looking over plot data, one may question why the product with the best average yield across multiple locations, does not have the highest yield at every location, why it does not win every plot, or possibly why its average ranking across multiple locations changes…
DetailsWith hot, dry weather comes the increased risk of charcoal rot. This fungal disease works opposite the normal crop fungal disease; its presence is most intense during hot, dry conditions rather than moist ones. It infects corn and soybean plants among others, but yield loss is most significant in soybeans. Agronomic Alert: Charcoal Rot in…
DetailsPurple seed stain and Cercospora leaf blight are caused by the fungus Cercospora kikuchii. Both phases of the disease are favored by wet conditions late in the season. With severe weather in August and September affecting the Southeast U.S. and East Coast, purple seed stain is showing up in soybean growing areas from Louisiana and…
DetailsRapid growth syndrome may be known by many aliases, including buggy whipping, accelerated growth syndrome, roping, wrapped whorls, onion leafing, twisted corn syndrome, and twisted whorls. Rapid growth syndrome describes a situation where, in random plants across a cornfield, the uppermost plant leaves are tightly rolled and do not unfurl normally. Agronomic Spotlight – Rapid…
DetailsSoybean bean leaf beetles (BLB) may be a threat to soybeans due to the potential for large, overwintered adult populations favored by the mild winter conditions. Early planted fields are at risk from BLB. Spotlight on Bean Leaf Beetles
DetailsRecent weather patterns have exposed corn to cold temperatures. Understanding the effects of these weather conditions on corn at different growth stages can help determine the best management options. Additionally, waiting three to five days after the weather event can allow for a more accurate assessment of plant health. Agronomic Alert- Cold temperatures on small…
DetailsPlanting conditions influence seedling emergence and corn growth throughout the season. Soil moisture, temperature, and structure, as well as residue cover are factors to be weighed against planting date. Last year’s compaction and dense layers created within the soil cannot be corrected when soils are wet, and tillage implements and planters should be operated on…
DetailsA corn refuge is the key component of an Insect Resistance Management (IRM) plan. Proper implementation of an IRM plan is important and mandatory for corn products that contain B.t. (Bacillus thuringiensis) technology or insect protection traits. Grower compliance is critical to the success of an IRM plan, and new requirements have been incorporated in…
DetailsQuestions arise every year regarding effects of seed size and shape on plantability and yield potential. Following manufacturers’ recommendations and considering tools to enhance plantability can help limit the risk of poor plantability. If plantability concerns related to seed size are managed properly, the effect of seed size may not significantly affect yield potential under…
