 For their practical use, the compounds and combinations according to the invention are rarely used alone. Most often they are part of compositions. These compositions, which can be used for the protection of plants against fungal diseases, or in plant growth regulating compositions, contain as active ingredient a compound according to the invention as described above in association with solid or liquid carriers, which are acceptable in agriculture and / or surfactants also acceptable in agriculture.

In particular, the usual inert carriers and surfactants are usable.

 By the term "carrier", in the present description, means an organic or inorganic material, natural or synthetic, with which the active ingredient is associated to facilitate its application on the plant, on seed or on the ground. This support is therefore generally inert and must be acceptable in agriculture, especially on the treated plant. The support may be solid (clays, natural or synthetic silicates, silica, resins, waxes, solid fertilizers, etc.) or liquid (water, alcohols, ketones, petroleum fractions, aromatic or paraffinic hydrocarbons, chlorinated hydrocarbons, liquefied gases , etc ...).

 The surfactant may be an emulsifier, dispersant or wetting agent of ionic or nonionic type. There may be mentioned, for example, salts of polyacrylic acids, salts of lignosulfonic acids, salts of phenolsulphonic or naphthalenesulphonic acids, polycondensates of ethylene oxide with fatty alcohols or with fatty acids or with fatty amines. substituted phenols (especially alkylphenols or arylphenols), salts of sulfosuccinic acid esters, taurine derivatives (especially alkyltaurates), phosphoric esters of polyoxyethylated alcohols or phenols.The presence of less a surfactant is generally indispensable when the active ingredient and / or the inert carrier are not soluble in water and the application carrier agent is water.

 For their application, the compounds of formula (I) and the associations are therefore generally in the form of compositions; these compositions according to the invention are themselves in fairly diverse forms, solid or liquid.

 As forms of solid compositions, mention may be made of dusting or dispersion powders (with a content of compound of formula (I) up to 100 t) and granules, in particular those obtained by extrusion, by compacting, by impregnation of a granulated support, by granulation from a powder (the content of compound of formula (I) in these granules being between 1 and 80 × for the latter cases).

 As forms of compositions which are liquid or intended to constitute liquid compositions during application, mention may be made of solutions, in particular water-soluble concentrates, emulsifiable concentrates, emulsions, concentrated suspensions, aerosols and powders. wettable (or powder spray), pasta.

 These compositions may also contain any other kind of ingredients such as, for example, protective colloids, adhesives, thickeners, thixotropic agents, penetration agents, stabilizers, sequestering agents, etc. other known active substances with pesticidal properties (in particular insecticides or fungicides) or with properties promoting the growth of plants (especially fertilizers) or with regulating properties of plant growth. More generally, the compounds according to the invention can be combined with any solid or liquid additive corresponding to the usual techniques of formulation.

 These doses of use in the case of use as fungicides of the compounds and combinations according to the invention can vary within wide limits, in particular according to the virulence of the fungi and the climatic conditions.

 In general, compositions containing 0.5 to 5000 ppm of active substance are suitable; these values are indicated for ready-to-use compositions. Ppm means "part per million." The zone from 0.5 to 5000 ppm corresponds to a zone of 5 × 10 5 to 0.5 × (percentages by weight).

 As regards the compositions suitable for storage and transport, they more preferably contain from 0.5 to 95% (by weight) of active substance.

 Thus, the compositions for agricultural use according to the invention may contain the active ingredients according to the invention within very wide limits, ranging from 5.10 5% to 95% (by weight).

 In general, the compositions according to the invention usually contain from about 0.05 to about 95% of active ingredients (formula I and group II) according to the invention, from about 1% to about 95% of one or more solid carriers. or liquids and optionally from 0.1 to 50%, preferably from 5 to 40%, of about one or more surfactants.

 The emulsifiable or soluble concentrates most often comprise 10 to 80% of active material, the emulsions or solutions ready for application containing, for their part, 0.01 to 20% of active material. In addition to the solvent, the emulsifiable concentrates may contain, when necessary, 2 to 20 v of suitable additives, such as stabilizers, surfactants, penetrating agents, corrosion inhibitors, dyes, adhesives previously mentioned.

For example, here is the composition of some concentrates Example (formulation) 1 - active ingredient 400 g / l - dodecylbenzene sulfonate alkaline 24 g / l - nonylphenol oxyethylated to 10 molecules
of ethylene oxide 16 g / l - cyclohexanone 200 g / l - aromatic solvent qs 1 liter
According to another formula of emulsifiable concentrate, it is used
Example F 2 - active ingredient 250 g - epoxidized vegetable oil 25 g - mixture of alkylaryl sulfonate and
of polyglycol ether and fatty alcohols 100 g - dimethylformamide 50 g - xylene 575 g
From these concentrates, emulsions of any desired concentration can be obtained by dilution with water, which are particularly suitable for application to the leaves.

 The concentrated suspensions, also applicable in spraying, are prepared in such a way as to obtain a stable fluid product which does not settle and usually contain from 10 to 75% of active substance, from 0.5 to 15% of surfactants, from 0 to 1 to 10% of thixotropic agents, from 0 to 10% of suitable additives, such as antifoams, corrosion inhibitors, stabilizers, penetrating agents and adhesives and, as a carrier, water or an organic liquid in which the active ingredient is little or not soluble: some organic solids or mineral salts may be dissolved in the support to help prevent sedimentation or as antifreezes for water.

 Wettable powders (or spray powder) are usually prepared to contain from 20 to 95% active ingredient, and usually contain, in addition to the solid support, from 0 to 5% of a wetting agent, to 10% of a dispersing agent, and, when necessary, from 0 to 10% of one or more stabilizers and / or other additives, such as penetrating agents, adhesives, or anti-caking agents, coloring agents, etc ...

For example, here are various compositions of wettable powders
Example F 3 - active ingredient 50% - calcium lignosulfonate (deflocculant) 5% - isopropylnaphthalene sulfonate (agent
anionic wetting agent) 1% - Anti-caking silica 5% - Kaolin (filler) 39%
Another spray powder composition at 70 uses the following constituents
Example F 4 - active ingredient 700 g - sodium dibutylnaphthylsulfonate 50 g - condensation product in proportions
3/2/1 naphthalene sulphonic acid,
of phenolsulfonic acid and
Eormaldehyde 30 g - kaolin 100 g - chalk of champagne 120 g
Another composition of 40% spraying powder uses the following constituents
Example F 5 - active ingredient 400 g - sodium lignosulfonate 50 g - sodium dibutylnaphthalene sulfonate 10 g - silica 540 g
Another 25% powder composition uses the following constituents

uses the following constituents
Example F 8 - active ingredient 100 g - mixture of sodium salts of sulphates
of saturated fatty acids 30 g - condensation product of naphtha acid
sulfonic acid and formaldehyde 50 g - kaolin 820 g
In order to obtain these sprayable powders or wettable powders, the active ingredients are intimately mixed in appropriate mixers with the additional substances and milled with suitable mills or other mills. Spray powders are obtained whose wettability and suspension are advantageous; they can be suspended with water at any desired concentration and these suspensions can be used very advantageously especially for application to the leaves of plants.

 In place of the wettable powders, pasta can be made. The conditions and methods of production and use of these pastes are similar to those of wettable powders or powders to be sprayed.

 As already mentioned, the aqueous dispersions and emulsions, for example the compositions obtained by diluting with water a wettable powder or an emulsifiable concentrate according to the invention, are included in the general scope of the present invention. The emulsions may be of the water-in-oil or oil-in-water type and may have a thick consistency similar to that of a "mayonnaise".

 The granules intended to be placed on the ground are usually prepared so that they have dimensions of between 0.1 and 2 mm and they can be manufactured by agglomeration or impregnation. In general, the granules contain 0.5 to 25% of active material and 0 to 10% of additives such as stabilizers, slow release modifiers, binders and solvents.

According to an example of granule composition, the following constituents are used
Example F 9 - active ingredient 50 g - epichlorohydrin 2.5 g - cetyl polyglycol ether 2.5 g - polyethylene glycol 35 g - kaolin (particle size: 0.3 to 0.8 mm) 910 g.

 In this particular case, the active ingredient is mixed with epichlorohydrin and dissolved with 60 g of acetone; polyethylene glycol and cetyl polyglycol ether are then added. The kaolin is sprinkled with the resulting solution and the acetone is then evaporated under vacuum. Such a microgranule is advantageously used for controlling soil fungi.

 The compounds of formula (I) and the combinations can still be used in the form of dusting powders; a composition comprising 50 g of active material and 950 g of talc can also be used; a composition comprising 20 g of active material, 10 g of finely divided silica and 970 g of talc can also be used; these constituents are mixed and milled and the mixture is applied by dusting.

 The following nonlimiting examples illustrate the invention and show how it can be implemented.

Example 11 ::
In vivo test on Erysiphe graminis f.sp.hordei on barley (barley powdery mildew)
Aqueous emulsion of the active ingredient to be tested having the following composition is prepared by fine grinding
- active ingredient to be tested 90 mg
- Tween 80 (surfactant constituted
of a polyoxyethylenated derivative oleate of the
sorbitan) diluted to 10% in water 0.45 mi
- water 90 ml.

 This aqueous emulsion is then diluted with water to obtain the desired concentration.

 Barley, sown in loam, is treated at the stage 10 cm high by spraying an aqueous emulsion (called slurry) concentration indicated below. The test is repeated twice. After 24 hours, the barley plants are dusted with Erysiphe graminis spores, the dusting being done with diseased plants.

 The reading is done 8 to 12 days after the contamination.

Under these conditions, the following results can be observed:
At a dose of 0.1 g / l, total protection (greater than or equal to 95%) with the compounds of Example 1 and the compound
A of Example 2.

Example 12
In vivo test on "Puccinia recondita" responsible for wheat rust
Wheat, in buckets, sown in loam, is treated at the stage 10 cm high by spraying with aqueous emulsions (called slurries) of the same composition as that described in Example 11 and at various concentrations of the test compound. . The test is repeated twice with each concentration.

 After 24 hours, an aqueous suspension of spores (50000 sp / cm3) is sprayed on the wheat; this suspension was obtained from contaminated plants. The wheat is then placed for 48 hours in an incubation cell at about 18 ° C. and 100% relative humidity.

 After 2 days, the relative humidity is reduced to 60%. The control of the condition of the plants is between the 11th and the 15th day after the contamination compared with the untreated control.

Under these conditions, the following results can be observed:
At a dose of 0.1 g / l, total protection with the compounds of Examples 1 and 2 (compound A).

Example 13
In vitro tests on seed fungi and soil fungi
The action of the compounds according to the invention is studied on the following fungi responsible for the secondary diseases of cereals P. solocercosporel herpotrichoides (CERC)
Helminthosporium gramineum (HELM G)
Botrytis cinerea (BOT)
Pyrenophorae avenae (PYRE)
Septoria nodorum (SEPT N) Tlelminthosporium teres (HELM T)
The indications in parentheses will be used to represent these fungi in Table (II).

 For each test, the procedure is as follows: a nutrient medium consisting of potato, glucose and gelose (PDA medium) is supercooled in a series of Petri dishes (20 ml per dish) after sterilization with autoclave at 1200C.

 During the filling of the dishes, an acetonic solution of the active substance is injected into the supercooled medium in order to obtain the desired final concentration.

 Petri dishes analogous to the preceding ones, in which similar amounts of a nutrient medium containing no active material are cast as a control.

 After 24 or 48 hours each boot is seeded by depositing a fragment of mycelium from a previous culture of the same fungus.

 The dishes are kept for 2 to 10 days (depending on the fungus tested) at 220 ° C. and the growth of the fungus is then compared in the dishes containing the active ingredient to be tested, to that of the same fungus in the can used as a control.

 For each test compound, the lowest dose is thus determined, making it possible to inhibit the development of the fungus in question by 80-100%. This dose is called "Minimal inhibitory concentration".

These minimum inhibitory concentrations, expressed in ppn, are reported in the following table in which the abbreviations have the meaning indicated above.
