Can spray adjuvants reduce herbicide movement? (Poster)

In the 1990s researchers in Europe worked on products that claimed to extend the life of pre-emergent herbicides soils such as trifluralin. Success was varied. Most were either vegetable oils and/or post-refined fatty acid derivatives. Although reducing herbicide leaching was not the primary aim of the experiments, the interesting result was that by extending the life in the soil, leaching of the herbicide was possibly reduced. Results were inferred in some publications rather than documented.
