Xtend Soybeans: Frequently Asked Questions


There are lots of questions with any new products, and that’s also the case with Xtend soybeans and the new herbicide  XtendiMax™ with  VaporGrip™  technology. Below are answers to frequently asked questions:

Q. Do Xtend soybeans yield as well as other soybeans?

A. The short answer is yes. Latham’s Xtend soybeans excelled in the 2016 F.I.R.S.T. Trials. Like any soybean variety, optimal yield is achieved by placing them in the correct environment.

Q. Does VaporGrip control drift?

A. VaporGrip does NOT control drift, but it does significantly reduces the potential of volatility.

Q. How can I control drift?

A. Here’s a summary of required application requirements:

  • Use nozzles and operating pressure listed on the herbicide product label to minimize driftable fines. These nozzles make bigger droplets that, when used with lower pressure and a minimum of 10 gallons of spray solution per acre, help minimize drift.
  • Use at the application rate of 22 fluid ounces per acre for any single, in-crop application.
  • Do not exceed a boom height of 24 inches above the target pest or soybean canopy.
  • Apply when wind speed is between 3-10 mph, and avoid application if there is no breeze at all.
  • Do not exceed 15 mph ground speed.
  • Do not apply when wind is blowing toward adjacent susceptible crops.

Q. Do I have to put in a buffer strip?

A. The label requires a buffer to protect sensitive areas. Read and follow the label instructions.

Q. Can I apply Ammonium Sulfate (AMS) with XtendiMax with VaporGrip?

A. Ammonium Sulfate and ammonium-based additives are prohibited in applications that include XtendiMax with VaporGrip Technology.

Q. Can I tank mix any Roundup with XtendiMax herbicide?

A. To find a list of approved products for tank mixing, click here. Before application, farmers and applicators should visit http://www.roundupreadyxtend.com/ to see if any new products have been approved for tank mixing.

Q. Am I required to use a residual herbicide with XtendiMax with VaporGrip?

A. You are not required to do so, but using a residual pre- and post-emergence strategy as outlined in the Roundup Ready Xtend Crop System for in-crop use will give better weed control and can net you $14/acre cash back.

Q. Do I get any residual activity with XtendiMax Herbicide with Vapor Grip?

A. You can get up to 14 days of soil activity from Dicamba on certain small-seeded broadleaf weeds to help other residual herbicides control weeds.

Q. Do I have to spray XtendiMax Herbicide on Xtend soybeans.

A. No, you can spray Xtend soybeans with any herbicide approved for Roundup Ready soybeans.
