Abstract

The invention provides the use as a pesticidal adjuvant of at least one citric acid derivative and compositions containing the derivative, which has a log octanol-water coefficient (log P) of 2.6 to 11 and an equivalent hydrocarbon (EH) value of 29 to 47. The invention has been shown to enhance the efficacy of a range of pesticides.
