Homogeneous stable liquid agrochemical concentrate formulations which form stable dilutions with water comprises biologically efficacious oil, water, agrochemical dissolved in the water to form concentrated aqueous electrolyte, a stabilizing surfactant, based on non-ionic or non-ionic and anionic or amphoteric surfactant, comprising oil compatible, electrolyte tolerant surfactant and water soluble, electrolyte tolerant surfactant and optionally a polyol component, are useful as tank mix adjuvants. The formulations combine biologically efficacious oil, e.g. crop oil, with an electrolyte agrochemical, particularly water soluble non-selective herbicide such as glyphosate, or electrolyte nutrients particularly water soluble inorganic fertilizers providing nutrients such as nitrogen, phosphorus, potassium or sulphur.
