Appeal No. 1998-1247
Application No. 08/445,165
BACKGROUND
The invention is directed to water dispersible granules of suspoemulsions.
Suspoemulsions are aqueous dispersions of solids of sufficiently high melting point, such
as isoproturon, and in which the solution of a second active substance, such as
fluoroglycofen ethyl, is emulsified. The selection of a solvent which does not evaporate
during the granulation process is required for the invention. (Specification, p. 2). The
granules are useful for crop production. Claim 17 which is representative of the claimed
invention is reproduced below:
17. Water-dispersible granules of suspoemulsions consisting essentially of
10 to 90% by weight of one or more pesticidally active substance as the
main component, said active substance having a melting point of more than
o
65 C, which can be formulated in the form of an aqueous dispersion,
0.1 to 20% by weight of one or more liquid pesticidally active substance or
o
a pesticidally active substance having a melting point below 65 C and/or
which is not sufficiently active in the solid state, in dissolved form,
0.2 to 20% by weight of a solvent or solvent mixture with a boiling point
o
above 170 C,
1 to 12% by weight of one or more wetting agents,
2 to 15% by weight of one or more dispersants,
0.2 to 5% by weight of one or more adhesives,
0.5 to 80% by weight of inert substance and
0.5 to 10% by weight of one or more emulsifiers.
As evidence of unpatentability, the Examiner relies on the following references:
