  • Soil treatment compositions and their use
    Patent number: 6397519
    Abstract: The invention provides an aqueous soil treatment composition comprising water and, (a) a calcium compound, (b) a water-soluble anionic polymer which has intrinsic viscosity of less than 30 dl/g and is formed from water-soluble monomer or monomer blend of which less than 40% by weight is anionic monomer.
    Type: Grant

  • Compositions comprising anti-drift agents and processes and methods for their use
    Patent number: 6288010
    Abstract: A composition (1) comprising water, in solution, a) an inorganic water-soluble compound in an amount of at least 10%, b) an anti-drift agent which is a water soluble anionic polymer of intrinsic viscosity at least 6 dl/g which is formed from water soluble monomer or monomer blend, characterized in that the water-soluble polymer (b) is present in an amount up to 1.9 wt. % based on weight of composition. Said composition (1) can be a liquid fertilizer concentrate that can conveniently be applied through conventional spray distribution equipment without the need for additional dosing of anti-drift control chemicals. Said composition (1) can be a low viscosity liquid anti-drift agent that can be combined with a herbicide or pesticide in conventional spray distribution equipment.
