European Patent Publication No. 0373953 published or 25th July 1990.
, BAD ORIGINAL A
By the term propagation product is meant all the generative parts of the plant which can be used for its propagation. These include, e.g., the seeds, roots, fruits, tubers, bulbs, rhizomes, and plant sections.
Germinated plants and young plants which are to be transplanted after germination or after emergence from the soil, may also be mentioned. These young plants may be protected, for example, before transplantation by a total or partial treatment by immersion. It is to be understood that the plant propagation products, for example seeds, can be treated in situ in the soil.
To choose the fungicides (b) suitable for the protection of the propagation products, those skilled in the art may usefully refer to the information given in reference works and which mention the absence of phytotoxicity of the said products.
Among these works, the plant-protection index, 1990 edition, ACTA 75595 PARIS CEDEX 12., may be mentioned.
The compositions according to the invention usually 20 contain between 0.5 and 95 % of active material. In this specification unless otherwise specified all percentages are by weight.
The term carrier in the present description denotes a natural or synthetic, organic or inorganic .5 material with which the active substance is combined in order to facilitate its application to the plant, to the
BAD ORIGINAL $
AP000221
- 3 plant propagation product, eg the seeds, or to the soil. This carrier is hence generally inert, and it must be agriculturally acceptable, in particular to the plant being treated. The carrier may be solid (eg clays, natural or synthetic silicates, silica, resins, waxes and solid fertilisers) or liquid (eg water, alcohols, ketones, petroleum fractions, aromatic or paraffinic hydrocarbons, chlorinated hydrocarbons and liquefied gases).
The surfactant can be an emulsifying, dispersant or 10 wetting agent of the ionic or nonionic type. There may be mentioned, e.g., polyacrylic acid salts, lignosulphonic acid salts, phenolsulphonic or naphthalenesulphonic acid salts, polycondensates of ethylene oxide with fatty alcohols or with fatty acids or with fatty amines, substituted phenols (in particular alkylphenols or arylphenols), salts of sulphosuccinic acid esters, taurine derivatives (in particular alkyltaurides) and polycondensates of ethylene oxide with phosphoric esters of alcohols or phenols. The presence of at least one surfactant is often required when the active substance and/or the inert carrier are not soluble in water and the carrier agent for the application is water.
These compositions can also contain other ingredients, such as, e.g., protective colloids, adhesives, thickeners, thixotropic agents, penetrating agents, stabilisers, sequestering agents, pigments, colourants and
BAD ORIGINAL polymers.
More generally, the compositions according to the invention may be combined with solid or liquid additives corresponding to the usual techniques of formulation for application to seed dressing, in particular.
It will be noted, in this connection, that, in the jargon of those skilled in the art, the term seed dressing refers, in fact, to treatment of the fertilised and ripened ovule.
The techniques of application are well known to those skilled in the art, and may be used within the scope of the present invention.
There may be mentioned, e.g., film-coating or encapsulation.
Among compositions, solid or liquid compositions may be mentioned.
As solid forms of compositions, there may be mentioned powders for dusting or dispersion (having a content of active material which can range up to 100 %) and granules, in particular those obtained by extrusion, by compaction, by impregnation of a granular carrier or by granulation from a powder (the content of active material in these granules being between 1 and 80 % for these latter cases).
The composition may also be used in the form of a dusting powder; a composition comprising active substance

- 5 (50 g), finely divided silica (10 g) , organic pigment (10 g) and talc (970 g) may thus be used; these constituents are mixed and ground and the mixture is applied by dusting.
As liquid forms of compositions, or forms intended for making liquid compositions when they are applied, there may be mentioned solutions, especially water-soluble concentrates, emulsifiable concentrates, emulsions, flowables, aerosols, wettable powders (or powder for spraying), pastes and dispersible granules.
The emulsifiable or soluble concentrates generally comprise 10 to 80 % of active substance, the emulsions or solutions ready for application containing for their part 0.01 to 20 % of active substance.
For example, in addition to the solvent, the emulsifiable concentrates can contain, when necessary, 2 to 20 % of suitable additives such as the stabilisers, surfactants, penetrating agents, corrosion inhibitors, colourants or adhesives mentioned above.
From these concentrates, emulsions of any desired concentration, which are especially suitable for application to seeds, may be obtained by dilution with water.
The flowables, also applicable by spraying, are prepared so as to obtain a stable fluid product which does not settle out, and they usually contain from 10 to 75 % of active substance, from 0.5 to 15 % of surfactants, from C.i
BAD ORIGINAL to 10 % of thixotropic agents, from 0 to 10 % of suitable additives such as pigments, colourings, antifoams, corrosion inhibitors, stabilisers, penetrating agents and adhesives, and, as a carrier, water or an organic liquid in which the active substance is soluble to only a slight extent if at all: some solid organic substances or inorganic salts may be dissolved in the carrier to assist in preventing sedimentation or as antifreezes for the water.
The wettable powders (or powder for spraying) are usually prepared so that they contain 20 to 95 % of active substance, and they usually contain, in addition to the solid carrier, from 0 to 5 % of a wetting agent, from 3 to 10 % of a dispersant agent and, when necessary, from 0 to
10 % of one or more stabilisers and/or other additives such as pigments, colourings, penetrating agents, adhesives or anti-caking agents.
To obtain these powders for spraying or wettable powders, the active substances are mixed intimately in suitable blenders with the additional substances and the mixture is ground using mills or other suitable grinders. Powders for spraying are thereby obtained, the wettability and suspendibility of which are advantageous; they may be suspended in water at any desired concentration, and these
-5 suspensions are very advantageously usable, especially for application to seeds.

- 7 In place of wettable powders, pastes may be made. The conditions and procedures for making and using these pastes are similar to those for the wettable powders or powders for spraying.
The dispersible granules are usually prepared by agglomeration, in suitable granulation systems, of compositions of the wettable powder type.
As already stated, the aqueous dispersions and emulsions, e.g. the compositions obtained by diluting a wettable powder or an emulsifiable concentrate according to the invention with water, are included in the general scope of the present invention. The emulsions can be of the water-in-oil or oil-in-water type, and they can have a thick consistency such as that of a '•mayonnaise''.
Among these compositions, those skilled in the art will advantageously choose that or those which are suitable according to the chosen combinations.
Preferably the weight ratio of the fungicide a) 2(4-chlorobenzylidene)-5,5-dimethy1-1-(1H-1,2,4-triazol-lylmethyl) -1-cyclopentanol to the fungicide(s) b) is between 1/400 and 400.
The propagation product is preferably a seed of a cereal, maize, rape, sunflower, soybean, alfalfa and rice. For potatoes, it is advantageously a tuber.
Compositions can be binary, ternary or quaternary according to the use for which they are intended.
