The composition may optionally include fungicidal combinations which comprise at least 1% of one or more compounds of formula (1) with another fungicide.

The compositions are either concentrated formulations which are dispersed in water for application, or are dust or granular formulations which are applied without further treatment. The 15 compositions are prepared according to procedures which are conventiona~ in the agricultural chemical art, but which are novel and important because of the presence therein of the compounds of this invention. Some description of the formulation of the compositions will, however, be given to assure that agricultural chemists can readily prepare any desired composition.

The dispersions in which the compounds are applied are most often aqueous suspensions or emulsions 2s prepared from concentrated formulations of the compounds. Such water-soluble, water suspendable, or emulsifiable formulations are either solids usually known as wettable powders, or liquids usually known as - . SUBSTITUTE SHEET (RULE 26) W 0~8,~'Ç15 PCTrUS97/13090 emulsifiable concentrates or a~ueous suspensions.
Wettable powders, which may be compacted to form water dispersible granules, comprise an intimate mixture of the active compound, an inert carrier and surfactants.
The concentration of the active compound is usually from about 10% to 90%. The inert carrier is usually chosen from among the attapulgite clays, the montmorillonite clays, the diatomaceous earths, or the purified silicates. Effective surfactants, comprising 10 from about 0.5% to about 10~ of the wettable powder, are found among the sulfonated lignins, the naphthalenesulfonates, alkylbenzenesulfonates, the alkyl sulfates, and non-ionic surfactants, such as, for example,- ethylene oxide adducts of alkyl phenols.
Emulsifiable concentrates of the compounds comprise a convenient concentration of a compound, such as from about 10% to about 50% of liquid, dissolved in an inert carrier, which is either a water miscible solvent or a mixture of water-immiscible organic solvents, and emulsifiers. Useful organic solvents include aromatics, especially the high-boiling naphthalenic and olefinic portions of petroleum such as heavy aromatic naphtha. Other organic solvents may also be used, such as, for example, terpenic solvents, including rosin derivatives, aliphatic ketones, such as cyclohexanone, and complex alcohols, such as 2-ethoxyethanol. Suitable emulsifiers for emulsifiable concentrates are chosen from conventional nonionic surfactants, such as those mentioned above.

Aqueous suspensions comprise suspensions of water-insoluble compounds of this invention, dispersed in an aqueous vehicle at a concentration in the range from about 5% to about 50%. Suspensions are prepared by finely grinding the compound, and vigorously mixing it into a vehicle comprised of water and surfactants chosen from the same types discussed above. Inert , W O ~'CC~15 PCTrUS97/13090 ingredients, such as inorganic salts and synthetic or natural gums, may also be added, to increase the density and viscosity of the aqueous vehicle. It is often most effective to grind and mix the compound at the same time by preparing the aqueous mixture, and homogenizing it in an implement such as a sand mill, ball mill, or piston-type homogenizer.

The compounds may also be applied as granular 10 compositions, which are particularly useful for applications to the soil. Granular compositions usually contain from about 0.5% to about 10% of the compound, dispersed in an inert carrier which consists entirely of in large part of clay or a similar 15 lnexpensive substance. Such compositions are usually prepared by dissolving the compound in a suitable solvent, and applying it to a granular carrier which a]has been pre-formed to the appropriate particle size, in the range of from about 0.5 to 3 mm. Such compositions may also be formulated by making a dough or past of the carrier and compound, and crushing and drying to obtain the desired granular particle.

Dusts containing the compounds are prepared simply by intimately mixing the compound in powdered form with a suitable dusty agricultural carrier, such as, for example, kaolin clay, ground volcanic rock, and the like. Dusts can suitably contain from about 1% to about 10% of the compound.
