ABSTRACT:
What is provided herein is an inert matrix composition (IMC), and a microemulsifiable concentrate (MEC) in the form of a free-flowing, high-melting solid, suitable for making an aqueous microemulsion (AME) of an agriculturally active chemical (AAC) with dilution water. The inert matrix composition comprises about 10-50% of a C.sub.6 -C.sub.18 alkylpyrrolidone, about 10-50% of an anionic surfactant and about 10-70% of a complexing agent characterized by being an organic compound having a melting point >100.degree. C., a molecular weight .ltoreq.500, a water solubility of at least 10% by weight, and being capable of hydrogen-bonding with the alkylpyrrolidone component of the composition. The MEC comprises the IMC and about 1-20% of the agriculturally active ingredient (AAI). Upon dilution with water an AMC is provided having a few ppm to 1% AAI.
