  • Patent number: 6051533
    Abstract: This invention relates to dry, water soluble, pesticidally acceptable particulate compositions, to a method of use thereof for killing or controlling pests including weeds and to a process for preparing such compositions. This invention also relates to dry, water soluble and/or water dispersible, pesticidally acceptable particulate herbicidal compositions containing one or more herbicides, a herbicidal method of use thereof and to a process for preparing such compositions. The dissolution or dispersible rates of particulate pesticidal compositions in water are enhanced by the presence of a small but effective amount of an organosilicone block copolymer wetting agent or a fluorocarbon wetting agent.

  • Patent number: 5994269
    Abstract: This invention relates to a novel aqueous agriculturally acceptable formulation, a process used to prepare it and a pesticidal method of using it in application to plants or weeds to kill or control plants or weeds. The formulation comprises an effective amount of N-phosphonomethylglycine or an agriculturally acceptable salt of N-phosphonomethylglycine and an effective amount of at least one C.sub.5 to C.sub.16 or preferably a C.sub.8 to C.sub.12 agriculturally acceptable fatty acid itself or in the form of an agriculturally acceptable water soluble salt or mixtures thereof. Other ingredients are optional, including surfactant(s), antifoam(s) and antimicrobial(s) or other ingredients such as pesticides including herbicides, insecticides and fungicides.

  • Patent number: 5985793
    Abstract: A novel method is provided wherein plants are first treated with an exogenous chemical (e.g., glyphosate herbicide) and then sequentially treated with a liquid accession agent which provides improved biological (e.g., herbicidal) effectiveness such that plants are controlled with lower rates of the applied exogenous chemical (e.g., glyphosate herbicide). Sequential application has been demonstrated to reduce the antagonism to herbicidal effectiveness that can be exhibited when the accession agent is added to a herbicide in a tank mix or simple coformulation. Typical accession agents employed in the disclosed method include a class of surfactants known as superwetting agents, such as certain organosilicone-based and fluorocarbon-based surfactants.

  • Patent number: 5912209
    Abstract: There is provided a new method of use of secondary or tertiary alcohol surfactants to enhance the efficacy and/or rainfastness of foliar-applied pesticidal and plant growth modifying agents. More specifically, there are provided new and useful compositions of such agents, in particular the herbicide N-phosphonomethylglycine or its salts or mixtures thereof, containing such efficacy-enhancing or rainfastness-enhancing surfactants.

  • Patent number: 5821195
    Abstract: A novel herbicidal method is provided wherein plants are first treated with a glyphosate herbicide and then sequentially treated with a liquid accession agent which provides improved herbicidal effectiveness such that plants are controlled with lower rates of the applied herbicide. Sequential application has been demonstrated to reduce the antagonism to herbicidal effectiveness that may be exhibited when the accession agent is added to the herbicide in a tank mix or coformulation. Typical accession agents employed in the disclosed method include a class of surfactants known as superwetting agents, such as certain silicone-based and fluorocarbon-based surfactants.
