A composite dispersing agent comprises an alkyl polyglycoside and a polymeric anionic dispersant. The alkyl polyglycoside can have the formula (I) R1-O-(R2O)b(Z)a wherein: R1 is a monovalent organic radical of 6 to 30 carbons; R2 is a divalent alkylene radical of 2 to 4 carbons; Z is a saccharide of 5 or 6 carbons; b is 0 to 12 and a is 1 to 6. The polymeric anionic dispersant can be a sulphonated lignin. The agent can also contain a nonionic, anionic, cationic or amphoteric surfactant such as a naphthalene sulphonate. A composition containing a pesticide and a composite dispersing agent as defined above is disclosed.
