More Gallons Per Acre Key to Success With Ignite

Chemical expert gives tips for better weed control.

There's a new kid on the block in the soybean market this summer. And Bayer, makers of Ignite for soybeans, say it's getting its feet wet, with an even bigger launch ready to go next spring. Right now, the main concern centers around advising farmers how to get the best job of weed control while using Ignite today on Ignite tolerant soybeans.

The product has been in the pipeline for some 15 years. It may be one of the longest waits until marketing occurred in the history of farm chemicals. Agrevo originally had the technology, and the chemical, then called Liberty. It's a non-selective herbicide like Roundup, a glyphosate, only it works by different means. The two products are not the same. Ignite on Roundup Ready beans will likely kill them. Meanwhile trying to spray Roundup instead of Ignite on Ignite tolerant soybeans will result in severe damage or death of plants.

Why all the fuss for a product that's been around for roughly 15 years in corn? Because now it's finally being OK'd for soybeans. In fact, this was the release year. Farmers in various areas of the Corn Belt got a chance to try the technology. Seed supplies were limited, and the trait was only available in a limited number of soybean varieties.

Plans for next year call for ramping up the supply, and a broadening of maturity groups. "We'll have them available in maturity ranges from Group 0.5 to Group 5.0," says Dave Doran, manager of the Bayer research farm near Brownsburg. That's a big increase over what was sold this year."

What Doran is talking about most right now is how to get a good kill with the product. Since it's not systemic like glyphosate, it must be applied differently to have the best effect. Plants take glyphosate into the roots, but the active ingredient in Ignite is a contact herbicide.'

Here's what Doran recommends. First, he says total gallons of water applied per water is crucial. He likes to use at least 15 gallons of water per acre. He prefers 20 gallons per acre, and used that number for most plots at the Brownsburg location.

"The best adjuvant for Ignite is simply more gallonage of carrier," he explains, not cracking a smile. "You want to either add more total gallons applied per acre or mix it with other chemicals,"

He also advises staying away from air induction nozzles, which generally makes small droplets. Small droplets are more prone to drift, and simply won't provide the coverage needed with this project.
