The USDA Economic Research Service released finding from a pesticide use study. Over the last five decades, pesticide use on corn, soybeans and other crops, as well as active ingredients, has changed dramatically in U.S. agriculture, including herbicide and insecticide use.
Wet or windy conditions may have kept farmers from applying a preemergence herbicide this spring. However, Bill Johnson and Travis Legleiter, experts from Purdue Extension say that many of these herbicides are still safe for farmers to use after corn has emerged so long as they pay close attention to product selection and application timing....More
Due to late planting, and then wet, cool weather last week, some farmers were unable to apply a pre-emergence herbicide to corn. The University of Nebraska-Lincoln has some tips for applying a residual herbicide after corn emergence, including reminding growers to not apply herbicide with nitrogen, There is also a chart with corn stages, weed growth and the appropriate herbicides to apply....More
A recent trial by the University of Minnesota showed that using a preemergence (pre) herbicide in soybeans is beneficial, offering a significant reduction in weed densities early in the season. Weed escapes at the end of the season were nearly eliminated when using a pre herbicide, as well....More
Geez, the margin for error shrinks constantly, especially with weed resistance. The latest bulletin on this theme relates to Palmer amaranth’s tight control window—before 4 inches high. That gives you about 10 days....More

From taking time to tune up equipment and refine weed and nitrogen management to yield gains from on-farm experiments, along with a fun farming parody on YouTube, these are articles you should read (or watch) while you're waiting to get in the field....More
Wet weather and cold temperatures have not only prevented the start of planting, they’ve prevented spring weed control. Ohio State University Extension offers 10 options for weed burndown, particularly in no-till....More
Cool soil in most of the Corn Belt means a low risk of nitrogen loss for now, says Emerson Nafziger, University of Illinois Crop Sciences professor. Advising farmers on best nitrogen practices for this spring, Nafziger offers these observations and pointers....More
Entomologists say it’s hard to predict insect challenges before a new season. But certain pests are perennial problems that require proactive tactics to limit their impact on yield. Two new tools for farmers in 2014 will help manage the productivity threats from corn rootworms (CRW) and from soybean aphids, beetles and stink bugs....More
Fertilizer prices have been increasing in recent months; however, per acre fertilizer costs should be lower in 2014 than in recent years. These are monthly prices for anhydrous ammonia, diammonium phosphate (DAP), and potash are shown for 2009 through 2014.
Difficult to control weeds – whether due to herbicide resistance or cut rates or too tall weed height/maturity or all of the above – must be taken very seriously and moved to the top of your agronomy to-do list for 2014....More
Are your crops getting the micronutrients they need when they need them? A recent Purdue University study suggests that it may be past time to pay more attention to micronutrient availability – if you plan to manage the high-yield details.
