These additives serve, for example, to improve the wetting capacity, the curing stability, to adjust the viscosity and to increase the low-temperature stability of the solutions.
  • the compounds of the formula I can, for example, also be combined with other fungicides. Such combinations can bring technical advantages. In many cases, the combination with other algicides is also advantageous.
  • the following examples further illustrate the invention. Parts or percentages are by weight.
  • Example 1 Determination of the minimum inhibitory concentration (MIC) for algae
  • the organisms against which fenpropidin is tested are grown in the Erlenmeyer in the nutrient medium under sterile conditions in a shaker at 24 ⁇ 2 ° C under light (16 hours light-8 hours dark change). Tests are carried out against 6 representative algae:
  • Algae and zoenobia-forming genera such as Scenedesmus subspicatus, found in the various biotypes.
  • the nutrient medium is composed as follows: 1.0 g sodium nitrate (NaNO 3 ), 0.05 g ammonium chloride (NH 4 CI) 0.058 g calcium chloride (CaCl 2 ), 0.5 g magnesium sulfate (MgSO 4 x 7 H 2 O) , 0.25 g of potassium dihydrogen phosphate (K 2 HPO 4 ) and 0.0024 g of iron trichloride (FeCI 3 ) are dissolved in 1 liter of distilled water. To improve the growth of the various algae, soil extract is added to the nutrient medium.
  • the nutrient medium mixed with the test substance (racemic fenpropidine, 0.001; 0.003; 0.01; 0.03; 0.10; 0.30; 1, 0 and 3.0 mg / l) is mixed with the respective algae suspension (9 Days old pre-cultures) inoculated so that a dilution of 1/50 to 1/625 is achieved.
  • the effectiveness is indicated via the minimum inhibitory concentration (MIC in mg / l), which indicates the test substance concentration at which the growth of the algae is still prevented. After 11 days of incubation with shaking, the algae growth is evaluated.
  • Table 1 minimum inhibitory concentration
  • Algae strain inhibitory concentration Algae strain culture
  • Tribonema aequale 1 500 0.03
  • Example 2 Use of the compounds of the formula I for protection against algae attack in anti-fouling lacquers.
  • a compound of the formula I in particular fenpropidine, is incorporated in antifouling paints.
  • an antifouling paint based on PVC copolymer / rosin (1.2: 1 parts by weight) is produced, as is known to the person skilled in the art.
  • the paint is spread on test panels. After drying (10 days at room temperature) the samples are hung in the Mediterranean (La Spezia / Italy). As a comparison, the corresponding colors are designed, but without the addition of a compound of the formula I.

Abstract

Les composés décrits répondent à la formule (I), dans laquelle R1 désigne alkyle C1-C12, cycloalkyle C3-C12 substitué ou non par alkyle C1-C4, phényle ou phénylalkyle C7-C9; R2 désigne hydrogène ou alkyle C1-C8; R3, R4, R5 et R6 représentent indépendamment les uns des autres hydrogène ou alkyle C1-C8, et X désigne oxygène ou -CH2-. Ces composés, ainsi que leurs sels d'addition d'acide, se prêtent particulièrement bien pour protéger des matériaux techniques, tels que le bois, les matières plastiques, les peintures, les vernis, notamment les vernis antisalissures, les matériaux d'étanchéité et les adhésifs contre l'infestation par des algues.
