Abstract

The invention concerns a suspension concentrate comprising, expressed by weight based on the total weight of the composition: a) 40 to 80% particles of dodecylguanidine or an acid salt of dodecylguanidine of the structure (1), wherein X represents an acid residue of a monocarboxylic, dicarboxylic or a mineral acid, b) 0 to 10% of an anti-freeze compound, c) 1 to 10% of a wetting agent and/or d) a dispersing agent, e) 0 to 5% of an antifoaming agent, f) remainder water characterized in that, the median diameter of the particles (d₅₀) is at least 7 μm and below 40 μm; and its use for the treatment of a fungicidal disease on crops or ornamental plants.

Claims

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., and

wherein 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.

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

a) at least 400 g of dodine particles/I, 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 selected from the group consisting of alkylphenol ethoxylates and tristyrylphenol ethoxylates;

d) 1 to 2% by weight of a dispersing agent, the dispersing agent comprising an acrylate graft copolymer;

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

e) 30 to 45% by weight water,

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

m;

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.; and

wherein 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.
