What is a Volatility Reduction Agent?
A Volatility Reduction Agent (VRA) is a tank mix adjuvant that delivers VaporGrip Technology to spray tanks solutions for reduction of dicamba volatility.
Why the EPA Requires VRA Adjuvants for Dicamba Applications
When dicamba is used as a herbicide there is the risk of drift into unwanted areas. The volatility of dicamba under certain circumstances increases this risk and can be mitigated by adding an adjuvant with VRA technology that decrease the volatility. The EPA therefore requires the use an an approved VRA adjuvant to be added to the tank solution when dicamba is used.
There are several factors that contribute to the volatility of dicamba:
- The type of dicamba (first generation vs later generation).
- Other tank-mix partners
- Overall solution pH
At a lower pH, the dicamba salt converts easily to dicamba acid. Dicamba acid is the volatile form which increases the volatility.
