This installment of 5 ag stories to read offers tips on assessing early-planted corn hail damage. Consider global fertilizer outlook and Chinese purchase of soybeans, as well as pesticide use in U.S. agriculture for the past five decades. And, have a little fun with a new soybean meme!...More
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
This roundup of 5 agriculture stories you should read offers steps to decide if soybeans should be replanted, as well as some info on soybean injury from soil-applied herbicides, and corn-soybean price ratios. Also, see how one farmer makes aerial scouting affordable, and check out some jazz-loving cows....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
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
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
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.
Long past are the days of tossing in a little crop oil or surfactant in a spray mix. Selecting the right adjuvant is increasingly important today. However, complex herbicide mixes to fight resistant weeds make proper adjuvant selection a critical part of a successful crop protection program....More
Denny Friest has conducted dozens of trials since 2000, and takes on several new comparisons each year through a program with Iowa Soybean Association. Participating farmers work with researchers to design practical trials. Farmers across the state often conduct trials on similar topics, such as N fertilizer or fungicide performance, which enhances results’ reliability....More
With expanding herbicide and corn-rootworm trait resistance, why let fungicide resistance get a seat at the table? Fungicide resistance in corn has yet to be identified. Checking resistance at the gate makes good agronomic and economic sense....More
When choosing a spring application, growers should expect a residual herbicide to deliver several weeks of weed control, cover a broad spectrum of weeds, aid in resistance management and allow for crop rotation flexibility....More
Corn and soybean farmers test-drove several new herbicides over the rugged proving ground of the 2013 growing season. The new active ingredient pyroxasulfone appears in three new products: Zidua, Anthem and Fierce.
Ohio State University experts have been receiving lots of questions recently, regarding which fungicide seed treatments to choose, which rates to use and the necessity of insecticide seed treatments....More
Take a post-harvest break from tillage to spend some valuable learning time next Tuesday and Thursday as Corn+Soybean Digest hosts two Nutrient Master Class meetings in Omaha, NE (Nov. 19) and Davenport, IA (Nov. 21). Co-sponsored with Wolf Trax, these complimentary, one-day events (breakfast and lunch included) will focus on fertilizer innovations and best management practices to maximize corn and soybean performance....More
You plan years ahead for crop rotation, fertilizer and machinery acquisitions. Since the rise of glyphosate-resistant weeds, you should be doing the same for your herbicide program, says Lisa Behnken, a Minnesota Extension crops specialist....More
The University of Illinois Extension has received many questions about applying herbicides post-harvest to control emerged marestail plants. Fall-applied herbicides often provide more effective and consistent control of emerged marestail as compared with spring-applied (i.e., burndown) herbicides, says Aaron Hager, weed specialist with U of IL Extension. Here are tips from the Extension service for fall-applying herbicide to control emerged marestail....More
With corn and soybean harvest underway in all major producing states, farmers are thinking about herbicide applications this fall. Aside from weed management, there are other factors to be considered when applying herbicide after harvest including: spring weather uncertainty, impact on soil conditions, pest interactions....More
Farmers who spray fungicide on corn “just as a precaution,” don’t have to worry this year about Extension specialists applying a guilt trip to them. Plant pathologists from several Corn Belt universities are suggesting fungicide applications on corn and others are recommending it. But farmers who apply a fungicide are doing it because there is more of a threat this year, than just doing it because it might boost the yield....More
