Abstract
The present invention provides a method for inhibiting microorganisms or plant pests using exfoliated clay/surfactant complex. The weight ratio of the exfoliated clay to the surfactant can range from 99/1 to 1/99. Preferably, the exfoliated clay is an inorganic layered clay on a nano scale and the surfactant is cationic, nonionic, anionic or amphoteric.
Claims10
