Claims
- 1. A water dispersible granule containing a pesticidal component, consisting essentially of 0.01%-30% by weight of the pesticidal component, 0.1%-10% by weight of tristyryl phenyl ether added thereon with polyoxyethylene, 1%-10% by weight of a sulfonate selected from the group consisting of sodium alkylnaphthalenesulfonate and sodium alkylbenzensulfonate, 1%-40% of a dispersion aid and 1%-50% by weight of a mineral powder carrier.
- 2. The water dispersible granule of claim 1 wherein the mineral powder carrier is selected from the group consisting of inorganic salt, diatomaceous earth, pyrophyllite-type clay and kaolinite-type clay.
- 3. The water dispersible granule of claim 1 wherein the pesticidal component is selected from the group consisting of triflumizole, thiophanate-methyl, hexythiazox and a benzamidoxime compound having the structural formula: ##STR15## wherein R.sup.1 is optionally substituted C.sub.1 -C.sub.4 alkyl, optionally substituted C.sub.2 -C.sub.4 alkenyl or optionally substituted C.sub.2 -C.sub.4 alkynyl,
- R.sup.2 is optionally substituted phenyl,
- X.sup.1 is C.sub.1 -C.sub.4 haloalkyl,
- X.sup.2, X.sup.3, X.sup.4 and X.sup.5 are each independently hydrogen, a halogen atom, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 haloalkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 haloalkoxy, C.sub.1 -C.sub.4 alkylthio, C.sub.1 -C.sub.4 alkysulfinyl, C.sub.1 -C.sub.4 alkysufonyl, nitro, amino or C.sub.1 -C.sub.4 alkycarbonylamino,
- r.sub.1 and r.sub.2 are each independently hydrogen, a halogen atom, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 haloalkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkylthio or amino, or r.sub.1 and r.sub.2 may jointly form a carbonyl group.
- 4. A method of making a water dispersible granule containing a pesticidal component consisting essentially of the steps of:
- (a) admixing 0.01%-30% by weight of the pesticidal component which is a solid at ambient temperature and is insoluble in water with
- (i) 0.1%-10% by weight of tristyryl phenyl ether added thereon with polyoxyethylene,
- (ii) 1%-40% by weight of a dispersion aid, and
- (iii) water to form a solution thereof;
- (b) subjecting the solution to a wet milling process to reduce the solid pesticidal component to a powder form;
- (c) then, separately, admixing 1%-50% by weight of a mineral powder carrier, 1%-10% by weight of a sulfonate selected from the group consisting of sodium alkylnaphthalenesulfonate and sodium alkylbenzenesulfonates, and 1%-40% by weight of the dispersion aid;
- (d) thereafter, subjecting the admixture to a dry milling process;
- (e) next, adding the mixture obtained from the wet milling process of step (b) to the admixture obtained from the dry milling process of step (d); and
- (f) thereafter subjecting the mixture obtained from step (e) to extrusion treatment whereby granules containing the powdered pesticidal component are obtained.
