NANOCOMPOSITE COMPOSITIONS COMPRISING MULTI-VALENT METAL MATERIAL AND IMMOBILIZED QUAT MATERIAL, METHODS OF MAKING THE COMPOSITIONS AND METHODS OF USING THE COMPOSITIONS
A nanoparticle for use within a composition for treating tomatoes as well as other agricultural products comprises: (1) a first shell layer comprising a leachant permeable base material in addition to a multi-valent metal (i.e., typically copper) material and (2) a second shell layer comprising a Quat material. Due to the multi-valent metal material and the Quat, the nanoparticle and the composition provide superior performance when treating tomatoes.
