If wet weather has delayed postemergence herbicide application to your soybean fields, there may be some large giant ragweed that needs treating. Mark Loux, Ohio State University, offers tips for herbicide application, depending on resistance levels....More
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.
After trading to almost $5.15 per bushel (just 17 trading sessions back, on May 6th to be exact) the new-crop DEC14 contract has dropped some $0.60 cents per bushel. I'm not calling this a bottom or looking for a complete turnaround, but I do think...More
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
From what I am hearing most end-users are about 65-75% covered through July but have next to nothing done for August. Obviously everybody is hoping imports will help resolve the situation, but no one is clearly certain about how this game will end.
Soybean traders are digesting the fact the US planting pace is now AHEAD of our traditional average. The USDA released data yesterday showing that 59% of the crop is now planted vs. 41% last year and 56% on average. In addition 25% of the crop is now "emerged" vs....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
Agriculture stories you should read today offer you a chance to comment to the EPA and learn more about corn rootworm resistance and sign up for succession planning workshops. They also remind growers that while planting, insecticide dust can impact bees, and that sometimes the rock that looks like a football on the surface is so large all you can do is bury it again....More
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
