PLACEHOLDER™, a VaporGrip® Xtra Agent
Placeholder, a VaporGrip Xtra Agent, is a Volatility Reducing Agent that can be tank mixed with XtendiMax® Herbicide with VaporGrip® Technology.
What is a Volatility Reducing Agent?
A Volatility Reducing Agent (VRA) is a tank mix adjuvant that delivers additional VaporGrip Technology to spray tanks solutions for further reduction of potential dicamba volatility.
Why is a VRA adjuvant required by the EPA for Dicamba?
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 like Placeholder to be added to the tank solution when dicamba is used.
There are several factors that contribute to the volatility of dicamba. At a lower pH, the dicamba salt converts easily to dicamba acid. Dicamba acid is the volatile form which increases volatility of the herbicide solution.
- The formation of dicamba acid is influenced by a number of factors:
The type of dicamba (first generation vs later generation). - Other tank -mix partners
- Overall solution pH
PLACEHOLDER, a VaporGrip Xtra Agent buffers against unwanted pH changes to prevent dicamba acid formation.
It is important to only utilize approved low-volatility dicamba and approved tank-mix partners such as PLACEHOLDER, a VaporGrip Xtra Agent for dicamba applications.
