Here are five agriculture stories you should check out today. 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
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
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
There's a new weed identification mobile app available for download. The Ag Weed ID app offers an image library, as well as control measures for about 75 of the most common weeds in a variety of crops, including corn and soybeans.
To manage Palmer amaranth weeds, growers must prevent the spread of the seed, or the weed; use multiple herbicide applications to control; and have a zero threshold of plants after control measures....More
Herbicide resistance doesn't develop overnight. By repeatedly applying the same herbicide or herbicides that use the same mode of action, weed resistance pressure increases. Farmers can take a proactive approach to weed management to tackle the weed resistance problem.
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
Seed treatment is all about reducing risk, especially in the first 72 hours of a plant’s life. And farmer use is proof. Aided by newer systemic fungicides and insecticides, their global sales more than tripled from $700 million in 1997 to $2.25 billion in 2010, and they’re estimated to reach $3.4 billion in 2016....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
"Insurance companies often have a pollution exclusion that they claim eliminates general liability and umbrella coverage for spray drift," warns Jean Sieler, Robison, Curphey & O'Connell, LLC. "Even if the policy covers drift via a specific rider, typically with a specific coverage limit, it may be an 'eroding' rider that allows them to deduct their legal costs."...More
The USDA Animal Plant and Health Inspection Service (APHIS) is seeking review and comment from the public on the possibility of deregulating corn and soybean seed that’s resistant to 2,4-D, among other herbicides....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.
It’s not at all clear how farmers would react if food companies are mandated to label their foods’ biotech status. Nor is it clear how food companies might change their product/marketing efforts beyond label wording....More
University of Illinois has received reports of corn yields of the outside 8 to 24 rows on the south or west edges of corn fields showing lower or much lower yields than corn farther into the field. Possible causes include application drift or weather....More
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
I've written about the Mix Tank app before, and now they've released an update. If you haven't already downloaded the app, do it now. It's an easy-to-use tool for spray management and chemical applications....More
More adverse spring weather and the northern spread of herbicide-resistant marestail find more reduced-tillage farmers considering fall residual herbicide applications. “Fall applications have risen dramatically in the last few years and will continue to grow,” says Regan Wear, CHS agronomy manager in Shipman, Ill. “Erratic, wet, cold springs have narrowed the planting window and fueled interest in fall residual herbicide applications because they really sharpen up timing the following spring.”...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
It’s non-GMO month, say natural food retailers. Really. Kind of a crazy irony, as you and your peers harvest millions of GMO crop acres. These are the same grains that we all have consumed in food for more than 17 years -- without a single instance of adverse health or environmental effects....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
