1. A suspension concentrate composition exhibiting long-term storage stability, the composition consisting of:

  • a) at least 400 g of dodine particles/l, and expressed by weight based on the total weight of the composition;

    b) 0 to 10% by weight of an anti-freeze compound;

    c) 1 to 10% by weight of a wetting agent;

    d) 0 to 2% by weight of a dispersing agent;

    e) 0 to 5% by weight of an antifoaming agent;

    f) 30 to 45% by weight water;

    wherein;

    the median diameter of the dodine particles (d50) is 7-20 μ

    m,the wetting agent is selected from the group consisting of alkylamine ethoxylates, acrylate graft copolymers, alkylphenol ethoxylates, alcohol ethoxylates, and tristyrylphenol ethoxylates;

    the suspension concentrate has a viscosity between 550 and 1,000 mPa-s, as measured with a Brookfield viscosity meter using a spindle 2, 20 rpm and 20°

    C., andwherein the suspension concentrate composition, prior to dilution, remains stable upon storage such that the dodine particles do not settle out of the suspension concentrate for a period of at least 12 months.
