  • Patent number: 5958463
    Abstract: The present invention relates generally to the method for the production of liposomal microencapsulated boron-containing products to be used for agricultural formulations. More specifically, a new method of production of liposomal microencapsulated is disclosed for active agents such as pesticides. A lecithin is mixed with an organic solvent in a certain proportion so as to provide solutions with varied levels of solubilized lecithin. The particular solvent being used will depend on the amount of active agent (AA) desired in the final solution. The formulation of the lecithin/organic solvent mixture is then allowed to settle. After settling, the top layer is separated and saved, while the bottom layer is discarded. An AA is then added to form a concentrate that is added to water for vesicle formation. Boron-containing materials formulated according to the invention may now be applied to agricultural field crops and fruits.

  • Patent number: 5928993
    Abstract: An aqueous composition which contains a low-foaming alkyl glycoside of the formula (I): ROG.sub.x wherein R is a branched alkyl group having 6-12 carbon atoms, G is a monosaccharide residue, and x is a number in the range of 1-5. When combined with a low-foaming amphoteric compound and/or a low-foaming nonionic alkoxylate, the composition has proved to have a surprisingly good wetting effect. In addition to the surfactant composition, the aqueous composition may contain active substances such as pesticides, herbicides, fertilizers, cleaning surfactants, and alkaline agents.

  • Patent number: 5922698
    Abstract: The invention relates to a pesticidal formulation having systemic activity and intended for application to a stem of a plant, which includes the compound methamidophos as an active ingredient, a suitable solvent for the active ingredient, and a colorant selected to impart an identifiable coloration to the formulation for a predetermined period of time related to the duration of the residual activity of the active ingredient. The solvent is preferably a non-volatile organic solvent selected for its low phytotoxicity and its low toxicity for humans, such as an aryl ethoxylate or a polyhydric alcohol. The colorant is preferably selected on the basis of its water solubility, having a limited solubility in water to be eluted gradually from the formulation over a period of time selected to coincide with the duration of the residual activity of the active ingredient. The formulation advantageously also includes an ingredient capable of screening ultra violet rays of the sun.
