XtendiMax™ is Now Labeled for Use...

Published on Friday, November 18, 2016

By now many of you are probably aware that the EPA has approved the use of the herbicide XtendiMax™ with VaporGrip™ technology for in-crop use in dicamba tolerant soybeans. The Roundup Ready 2 Xtend® soybeans will have tolerance to both glyphosate as well as dicamba. Currently, the XtendiMax label only has a two-year registration. The EPA has reserved the right to rescind the label if they feel the product is being misused, is having a negative impact on the environment and general public impact, or is having a high number of off-target incidents.

Monsanto’s XtendiMax formulation is a DGA salt (Clarity®) combined with VaporGrip technology. With this new technology, volatility will be reduced by 95 percent compared to the current dicamba products on the market. XtendiMax can be applied pre-plant, at-planting, pre-emergence, or as a post-emergence application. All other current dicamba formulations will be prohibited from being used in-crop on dicamba tolerant soybeans.

The use rate for XtendiMax will range from 22 to 44 oz./A. The most common use rate of 22 oz./A. equates to a pint of the current dicamba products on the market. The 22 oz./A. rate will be the maximum rate allowed for post-emerge applications, but we will have a very wide window of application from pre-plant through R1 or beginning bloom. As of today, we do not have the ability to tank mix any products (Roundup®, residuals, etc.) within a single application of XtendiMax. This also means we will not be able to direct-inject herbicides from a separate tank on the go.

Additional Application Requirements:

  1. The only approved nozzles are TTI11004

  2. The maximum nozzle pressure is 63 psi

  3. There is a minimum volume of 10 gal./A.

  4. Only apply when wind is less than 15 mph

  5. Apply 24 in. above canopy

  6. Maximum 15 mph ground speed

  7. 110 ft. buffer required downwind to sensitive crops or areas (22 oz. use rate)

Now that we have approval, the real question is will the Xtend system work for you? Roundup Ready 2 Xtend soybeans and the XtendiMax herbicide will provide excellent control of the weeds we struggle with today such as Palmer amaranth, tall waterhemp, common and giant ragweed, and marestail. Can we eliminate the need for 2,4-D at pre-plant which would allow for earlier soybean planting to take place? Our Practical Farm Research (PFR)® results continues to demonstrate the value and yield impact of planting earlier in April. These are all things to take into consideration when deciding if the Xtend system is right for your farm. 

When making your soybean seed decision, always remember to choose the best germplasm for your soils and situation. When we evaluate potential soybean varieties at Beck’s, we aim to eliminate all the variables that could adversely affect our evaluation of a product. By evaluating all our soybean products in the same soil, with the same management practices, we are able to choose the top-performing products for our customers independent of the herbicide platform.

Have a safe and Happy Thanksgiving!



 

 

 

 

 

 

 

 

 

Roundup Ready® crops contain genes that confer tolerance to glyphosate, the active ingredient in Roundup® brand agricultural herbicides. Roundup® brand agricultural herbicides will kill crops that are not tolerant to glyphosate. Roundup Ready 2 Xtend® Soybeans contains genes that confer tolerance to glyphosate and dicamba. Glyphosate herbicides will kill crops that are not tolerant to glyphosate. Dicamba herbicides will kill crops that are not tolerant to dicamba. Roundup Ready 2 Xtend™, Roundup Xtend™, VaporGrip™ and XtendiMax™ are trademarks of Monsanto Technology LLC. Individual results may vary, and performance may vary from location to location and from year to year. This result may not be an indicator of results you may obtain as local growing, soil and weather conditions may vary. Growers should evaluate data from multiple locations and years whenever possible. Seeds containing the Genuity® Roundup Ready 2 Yield® or the Roundup Ready 2 Xtend® traits can only be used to plant a single commercial crop. It is unlawful to save and replant Genuity® Roundup Ready 2 Yield® or Roundup Ready 2 Xtend® soybeans. Additional information and limitations on the use of these products are provided in the Monsanto Technology Stewardship Agreement, the Monsanto Technology Use Guide, and 2016 Technology Use Guide Addendum to include Roundup Ready 2 Xtend® Soybeans.
