New adjuvant class to reduce dicamba vapour drift
The
rising sales of over-the-top dicamba products goes hand in hand with a
sharp increase in dicamba injury lawsuits. The new US EPA labels require
the addition of an approved pH-buffering
agent to control volatility for these low-volatile dicamba
formulations. This decision has forced the development of a new class of
adjuvants. Adjuvants & Formulations reports on the latest developments.

News in brief
Viscoelasticity
and strain, not dynamic surface tension and viscosity, determine the
effects on drop size and thus on drift. Chinese chemists conclude this
from systematic investigations into effects of adjuvants on droplet
size, dynamic surface tension and rheology of an emamectin benzoate
dilute emulsion. Adjuvants & Formulations presents the major findings of this study.
More news in this issue:
- Adjuvant effects on peanut tolerance to applications of PPO-inhibitor herbicides.
- Nanocrystal-based formulations against peanut smut.
- Common errors in dose–response analysis and how to avoid them.
- Physical stability, oxidative stability and bioactivity of nanoemulsion delivery systems.
- Encapsulation strategies for Bacillus thuringiensis.
- Future canopy spray application technology in specialty crops.

Patents in brief
Metal
ions can form stable complexes with prothioconazole, thus preventing
degradation of this conazole fungicide. In case these complexes do not
break easily, the availability and, consequently, the efficacy of the
conazole fungicide is low.
A de-complexing
agent incorporated in the formulation, or added separately when
preparing the spray solution, can break these complexes when they are no
longer needed.
Adjuvants & Formulations also reports about activities of other companies as well as universities, such as:
- Shear-stable cationic polymer as drift control agent
- Stabilised suspension concentrates
- Hydrogel as carrier for biocontrol agent of slugs and snails
- Alginate sludge composition as delivery system
- Solvents for spidoxamat suspension concentrates
- Overview of recent patent publications with brief summary
