XtendFlex platform surprises growers

DELPHI, Ind. — When it comes to change, many growers may be hesitant to move from a tried and true system that has proven results. Growers who previously used the DEKALB Asgrow Xtend soybean lineup were no different.

“They were worried about switching to a new platform that they might have a hiccup. Everybody has been very impressed with the XtendFlex technology and we just keep growing,” said Jason Harmon, DEKALB Asgrow technical agronomist in Indiana.

Harmon said the Asgrow XtendFlex lineup of soybeans has surprised growers in a good way in northern Indiana.

“That is my favorite thing to hear growers say, ‘I was a little hesitant to see us switch platforms, but it’s actually turned out as strong as if not better than the Xtend lineup,’” Harmon said.

Above And Beyond

Harmon said early indications are that the soybean crop in his area is turning out better than expected.

“We had high expectations going into August. We know the month of August can impact soybean yields greatly. If we don’t receive timely moisture during the final soybean reproductive stages, yields can be limited due to the overall soybean seed size obtained. Ample heat and moisture in August can significantly increase soybean seed size, a large component to yield.”

We didn’t have moisture here in northern Indiana. We weren’t sure how yields were going to end up. Initial indications of yields from early maturities seem to be pretty good,” Harmon said.

When he’s counting beans, Harmon said bean size is a significant factor this year with the XtendFlex lineup.

“I am pleased with the overall bean size. I think that is going to be the big difference this year, the overall size of the bean. That is what I see right now, with early indications of these group 2.0 up to 3.0 is where we are and it looks good,” Harmon said.

The XtendFlex soybean lineup, with its strong genetic potential, has come out strong.

“The XtendFlex lineup is such a strong lineup. We are on our fourth generation of XtendFlex. We are building off of our previous Roundup Ready 2 and Xtend platforms. A lot of these genetics we are seeing, we have a really good idea of how they are going to perform right out of the gate. We have a good history on the genetic parents of these products. It’s been exciting to see them do exactly what we want them to do while providing upside,” Harmon said.

Go Your Own Way

Harmon said the XtendFlex lineup offers growers flexibility in their weed control options along with the genetic yield potential.

“Our growers want a bean that is going to yield, and they want to be able to take care of the weeds that can come into the field. With XtendFlex, utilizing Roundup, Liberty and dicamba as post options offers a great toolbox for determining when and where we need one or all these tools to control certain weeds,” Harmon said.

For growers who may be hesitant to use dicamba later due to cutoff dates or weather conditions, the XtendFlex lineup offers pre and post options.

“Dicamba is a talking point around the countryside. Some farmers just don’t want to utilize that product. That’s fine. We can use Roundup and Liberty. If you are hesitant, we do suggest getting it out early because there is great knock down with residual using dicamba. With our cutoff date here in Indiana, that is one thing we have to keep in mind. But if we want to use dicamba earlier in the season, we still have Liberty and Roundup as good post options,” Harmon said.

The main theme of weed control in soybeans that Harmon emphasized is the “start clean, stay clean” approach.

“If we utilize good pre’s, plus tillage, or a pre alone, and then come back early with dicamba, layering Group 15s, that’s an awesome program. Making sure we have a Group 15 such as Warrant herbicide packaged in there will keep waterhemp and all these later weeds we see, when rain does come, at bay. If we keep layering those residuals, we start clean, stay clean. We go out there early with dicamba and the Group 15. When we come back in June, we utilize another Group 15, along with Liberty or Roundup or all three, trying to layer in residuals,” Harmon said.
