Multi-layer adjuvants for controlled delivery of agro-materials into plant tissues

Zeev Wiesman (Inventor), Arie Markus (Inventor)

Research output: Patent


Composition for the treatment of plants, that is a structural combination of agro-materials and adjuvant formulations. A specific composition is a particulate material in which the agro-material particle constitutes the nucleus of each composition particle and adjuvant formulations constitute a coating of the composition particle. The adjuvant formulations comprise a plurality of components, which constitute substantially superimposed coating layers in each particle of the composition and preferably comprise a combination of lipophilic and hydrophilic cuticle surface active agents, wetting agents, thickening agents and fatty self-emulsified components. Special compositions are those in which different agro-materials are used. The agromaterials are chosen from fertilizers, trace elements, plant growth regulators, biostimulants, pesticides, herbicides and insecticides. The invention also relates to methods of treating plants by applying the agro-material compositions, and to methods of preparing the agro-material compositions.
