Preparation Examples).

The active compounds usable according to the invention have a strong resistanceinducing activity in plants. They are therefore suitable for generating resistance in plants against attack by unwanted microorganisms.

S Resistance-inducing compounds in the present context are substances which are capable of stimulating the defence system of plants in such a way that the treated plants, when subsequently inoculated with unwanted microorganisms, are largely resistant against these microorganisms.

In the present case, unwanted microorganisms are phytopathogenic fungi, bacteria and viruses. Thus, the compounds according to the invention can be employed to generate resistance in plants against attack by the abovenentioned harmful organisms for a certain period after the treatment. The period for which resistance is generated generally extends over 1 to 10 days, preferably 1 to 7 days, after the treatment of the plants with /th4ctive compounds.

19- In addition to the resistance-inducing activity, the active compounds usable according to the invention also have strong microbicidal activity, and they are also employed in practice for the direct control of unwanted microorganisms. The active compounds are suitable for use as crop protection agents, in particular as fungicides.

In crop protection, unwanted microorganisms include fungi from the classes of the Plasmodiophoromycetes, Oomycetes, Chytridiomycetes, Zygomycetes, Ascomycetes, Basidiomycetes, Deuteromycetes.

1 Bactericides are employed in crop protection for controlling Pseudomonadaceae, Rhizobiaceae, Enterobacteriaceae, Coryniebacteriaceae and Streptomycetaceae.

Some pathogens causing fungal and bacterial diseases which come under the generic *.Ogg: names listed above are mentioned as examples, but not by way of limitation: 15 Xanthomonas species, such as, for example, Xanthomonas campestris pv. oryzae; Pseudomonas species, such as, for example, Pseudomonas syringae pv. lachrymans; Erwinia-species, such as, for example, Erwinia amylovora; Pythium species, such as, for example, Pythium ultimum; Phytophthora species, such as, for example, Phytophthora infestans; 20 Pseudoperonospora species, such as, for example, Pseudoperonospora hurnuli or Pseudoperonospora cubensis; Plasmopara species, such as, for example, Plasmopara viticola; Bremia species, such as, for example, Bremia lactucae, Peronospora species, such as, for example, Peronospora pisi or P. brassicae; Erysiphe species, such as, for example, Erysiphe graminis; Sphaerotheca species, such as, for example, Sphaerotheca fuliginca; Podosphaera species, such as, for example, Podosphaera leucotricha; Venturia species, such as, for example, Venturia inacqualis; ,..,Pyrenophora species, such as, for example, Pyrenophora teres or P. graminea R nidia form: Drechslera, syn: Helminthosporiurn); Cochliobolus species, such as, for example, Cochliobolus sativus (conidia form: Drechslera, syn: Helminthosporium); Uromyces species, such as, for example, Uromyces appendiculatus; Puccinia species, such as, for example, Puccima recondita; Sclerotinia species, such as, for example, Sclerotinia sclerotiorum; Tilletia species, such as, for example, Tilletia caries; Ustilago species, such as, for example, Ustilago nuda or Ustilago avenae; Pellicularia species, such as, for example, Pellicularia sasakii; Pyricularia species, such as, for example, Pyricularia oryzae; S 10 Fusarium species, such as, for example, Fusarium culmorum; Botrytis-species, such as, for example, Botrytis cinerea; Septoria species, such as, for example, Septoria nodorum; 9 Leptosphaeria species, such as, for example, Leptosphaeria nodorum; Ccrcospora species, such as, for example, Cercospora canescens; 15 Alternaria species, such as, for example, Altemaria brassicae; and Pseudocercosporella species, such as, for example, Pseudoccrcosporella herpotrichoides.

The fact that the active compounds are well tolerated by plants at the concentrations required for controlling plant diseases permits the treatment of aerial parts of plants, of 20 propagation stock and seeds, and of the soil.

The active compounds usable according to the invention can be employed particilarly successfully for controlling rice diseases, such as Pyricularia species, or diseases in viticulture and fruit and vegetable growing, such as, for example, Uncinula species, and they can also be employed very successfully against cereal diseases such as powdery mildew.

Depending on their particular physical and/or chemical properties, the active compounds can be converted to the customary formulations, such as solutions, emulsions, %Rq suspensions, powders, foams, pastes, granules, aerosols and microencapsulations in polymeric substances and in coating compositions for seeds, and ULV cool and warm 1//fo2iine formulations.

-21- These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents, liquefied gases under pressure, and/or solid carriers, optionally with the use of surfactants, that is emulsifiers and/or dispersants, and/or foam formers. If the extender used is water, it is possible to use for example organic solvents as auxiliary solvents. Essentially, the following are suitable as liquid solvents: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions, alcohols such as butanol or glycol and their ethers and 10 esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide or dimethyl sulphoxide, or else water.

Suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite 20 and dolomite, or else synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks.

Suitable emulsifiers and/or foam formers are: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates, or else protein hydrolysates. Suitable dispersants are: for example lignin-sulphite waste liquors and methylcellulose.

-22- Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, or else natural phospholipids such as cephalins and lecithins and synthetic phospholipids can be used in the formulations. Other additives can be mineral and vegetable oils.

15 About 20 Lucilia cuprina res. larvae are introduced into a test-tube which contains about I cm 3 of horse meat and 0.5 ml of the active compound preparation. After 48 hours, the activity of the active compound preparation is determined. The test-tubes are transferred in a beaker having a bottom covered with sand. After a further 2 days, the test-tubes are removed and the pupae are counted.

The activity of the active compound preparation is determined by the number of the flies that have hatched after 1.5 times the development time of an untreated control.

100% means that none of the flies have hatched; 0% means that all the flies have hatched normally.

In this test, the active compound listed in Example 31 exhibits, at a concentration of 1000 ppm in the active compound preparation, an efficacy of 100%.
