VaporGrip® Xtra Agent

Additional Reduction of Potential Volatility

VaporGrip® Xtra Agent is a tank mix adjuvant that delivers additional VaporGrip® Technology to further reduce potential dicamba volatility.

Volatility Reducing Agent

What factors contribute to volatility?

The availability of protons (H+) in solution significantly increases the potential for dicamba acid to be formed. Dicamba acid is the volatile form and can potentially volatilize. The availability of protons is influenced by a number of factors including salt of dicamba, tank-mix partners and overall solution pH. Therefore, it is important to only utilize approved low-volatility dicamba and approved tank-mix partners for applications.

How does VaporGrip Technology work?

VaporGrip Technology binds protons (H+) and removes them from the spray solution to significantly limit the formation of dicamba acid.

What is VaporGrip Xtra Agent?

VaporGrip Xtra Agent is a tank-mix adjuvant that delivers additional VaporGrip Technology to spray tanks for further reduction of potential dicamba volatility.

What is the use rate of VaporGrip Xtra Agent?

VaporGrip Xtra Agent should be used at a minimum rate of 20 oz/A.

Has VaporGrip Xtra Agent been tested?

VaporGrip Xtra Agent has been thoroughly tested* in field trials by Bayer and U.S. academic weed scientists.

How VaporGrip Technology Works

Illustrated example of what happens when you plant with VaporGrip Technology

In the tank, there is the potential for dicamba acid (DCH) to form in the solution and create off-target movement of dicamba through volatility after spraying.

Illustrated example of what happens when you plant without VaporGrip Technology

In the tank, VaporGrip Technology reduces the formation of (DCH) in solution, minimizing volatility potential of dicamba after spraying.

Bayer Humidome** Trials - VaporGrip Xtra Agent Performance

Bayer Humidrome trail results chart

Humidome** studies measuring the air concentration of dicamba demonstrate that VaporGrip Xtra Agent provides additional volatility reduction.

VaporGrip Xtra Agent Performance was Validated Through Low-Tunnel Trials Conducted in cooperation with U.S. Academic Weed Scientists across key soybean growing areas

Low-tunnel trials provide field evaluation of soybean plant response due to dicamba volatility.
The method was developed and executed by Bayer and U.S. academic weed scientists.
- Treatments are conducted at 4x the field use rate to separate low-volatility treatments (see details below).
- Each treatment was applied to two flats of soil.
- Soil was treated at a remote location and transported to the test site.
- Soil flats were wetted to field capacity the night before the trial.
- Flats were exposed to the crop for 48 hours.
- Crop injury ratings were taken 14 and 28 days after treatment.
- Temperature under the hoop house was monitored with a weather station (in many cases, air temperature was 100-120 degrees).

Twenty low-tunnel trials were conducted by U.S. academic weed scientists 14 days after treatment
