Dow offers new "burndown" herbicide

SUBHEAD: welcomes GMOs, herbicides and global warming drought for profits.

Earlier this year, we reported that Marestail was an early concern for growers.  Now that growing season is approaching its half way point growers are looking at soybean fields to find unwanted marestail plants competing with their crops.  While marestail is not new to Midwest growers, herbicide-resistant marestail continues to spread.  This is making it hard to control with glyphosate (RoundUp) alone.

CropLife Magazine is reporting that pending registration; Elevore herbicide will provide accurate control of many glyphosate- and ALS-resistant weeds which include marestail up to 8 inches tall.  This herbicide is expected to control and suppress costly and high-anxiety weeds when applied as part of a grower’s burndown program before planting.

Elevore contains Arylex active, a new Group 4 growth regulator herbicide developed by Dow AgroSciences. Arylex works to control weeds from the inside out to provide thorough control of labeled weeds.

In field trials conducted by Dow AgroSciences, Elevore tank-mixed with 2,4-D (50% of ingredient of Agent Orange) delivered 97% control of glyphosate-resistant marestail when applied in a pre-plant burndown program.

Left abandoned, marestail can grow and consume a soybean field.  According to Michigan State University, an estimated 83% of soybean yield is lost from 105 marestail plants per 10 square feet.  According to Jeff Ellis, Ph.D., field scientist at Dow AgroSciences, he says that it’s important to control marestail early, before soybean plants begin to emerge, for maximum yield potential at the end of the season.

Once Elevore is registered, it will be labeled for application with commonly used residual and burndown tank-mix partners, including glyphosate and 2,4-D, up to 14 days before planting soybeans in the Midwest.  Registration for Elevore is expected in 2017.

Upside of Climate Change
SUBHEAD: Will drought be the Silver Bullet for corn prices in 2016?

The USDA report that broke on June 30th brought with it bad news for growers; the 3rd largest crop ever planted and with it came a sharp decline in commodity prices. Growers are now hoping that a large scale drought will allow for prices to rally. However, growers are looking for the rally in all the wrong places.

I’ve seen a lot of tweets about the lack of rainfall in parts of Southern Iowa, eastern Nebraska and Kansas, and western South Dakota from growers. Everyone is hoping that drought impacts the crop, just not their fields so that prices may rise and they can take advantage of it. Many are hoping we have a summer like 2012.

A lot of growers are hoping for a 2012 type year in regards to drought. Comparing the 2012 Drought Monitor issued at the same time as this week’s, growers can hope for a drought, but this is not the forecast.

Whenever you wish for a forecast we call that “wishcasting” in the meteorological world. The facts don’t support the case for a large scale drought to hit. We are in much better shape this year than in 2012. In 2012, we saw 72% of the country in at least some form of drought at the same time. This year, only 43% of the country is in some form of drought.

More importantly, in 2012, 30% of the country was in a moderate to severe drought which was spread out over a large area compared to just 5% of the country this year and most of it is isolated to California.

We’re entering the part of the year where the Corn Belt receives large amounts of rainfall from squall lines.  Last weekend it rained in Eastern Kansas and Missouri, where a stalled front produced widespread heavy rain which is typical of this time of year.

The longer range forecast, for July into August, is for warmer than normal temperatures across a widespread area.

It's rare, but agronomists may get a year where we can directly monitor the effect heat is going to have on the crop without drought over a large area.

All the more reason that this year, companies that serve agronomists and growers need to have access to high-resolution field level weather. Temperature, precipitation, and potential evapotranspiration are going to need to be monitored to identify areas that will have both heat and lack of rainfall, as well as which areas may just have high heat; especially during pollination.

The weather is going to vary strongly this year, especially with precipitation, but understanding where these areas are, can lead to better management practices.

For instance, growers who irrigate can mitigate heat stress during the R1 stage by applying a .2-.4" pass over their fields.  Growers who don’t have irrigation need to pay close attention to nitrogen and phosphorous levels, and implement a fertility management program, as this can also mitigate the effect heat will have on the crop.

Are you feeling the effects of a drought or close to it? Post your thoughts in the forum!


The first of its kind – is a community-based website geared specifically toward producers with large commercial farming operations. It’s a place for anyone involved in production agriculture or large-scale operations to read articles relevant to their fields, learn about and discuss topics in our forum, interact with and learn from our social community of other Big Ag farmers as well as search for equipment – all on one site!

Fastline Publications launched the Big Ag catalog in 2011. This specialized catalog is delivered only to large-acre producers and features larger equipment and products necessary to run commercial operations. Readers love their Big Ag, but they want more. In response, Fastline developed The Big Ag print catalog and online community strive toward the same goal of providing large-acre farmers the information they need to optimize their operation.

The term Big Ag means different things to different people. We aim to gather information from the best in the industry. We are proud of our Big Ag producers and the work they do to feed and fuel America and the world. We hope that provides information and a platform to help strengthen the Big Ag community.
