Soil surfactants improve rewettability of
water-repellent soils and growing media
Surfactants
can prevent or reduce dry zones in potato hills. In this way these
surface active agents can improve water and nutrient uptake. In a dry
year Dutch researchers found a reduction of the incidence of scab in
plots treated with a soil surfactant. Adjuvant Newsletter presents a
state-of-the-art of rewetting water-repellent soils and potting media by
surfactants. Picture by researchers.

Patents in brief
Specific thickeners can maintain a
suspension or dispersion of solid particles in an oil medium. With this
effect, these patent pending thickeners enable a significant higher
weight ratio of solid particles in such suspension compositions as
compared to previously known compositions.
Other patent applications in this issue of the Adjuvant Newsletter cover granular formulations of low-melting agrochemicals, novel nano-sized herbicide formulations, a controlled-release formulation to improve the retention of 1-MCP in a spray solution and sulphur and mineral oil in one synergistic insecticidal composition.
