<p>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 C6-C18 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 °C, a molecular weight < 500, a water solubility of at least 10 % by weight, and being capable of hydrogen-bonding with the alkylpyrrolidone component of the composition. The complexing agent may be fructose, glucose, lactose or urea. The MEC comprises the IMC and about 1-20 % of the agriculturally active ingredient (AAI) which may be an insecticide, herbicide, fungicide, growth regulant, repellant, rodenticide or pesticide, and is preferably carbaryl. Upon dilution with water an AME is provided having a few ppm to 1 % AAI.</p> |
