Embodiment

[0047] preparation

[0048] The preparation according to the invention is obtained by mixing a titanium oxide dispersion with a superspreading agent.

[0049] The titanium oxide dispersion has a titanium oxide content of 35% by weight. Furthermore, it contains 21% by weight of polyacrylic acid and 46% by weight of water.

[0050] The titanium oxide used is pyrolytically prepared aggregated titanium oxide powder with 50m 2 / g of BET surface area.

[0051] Use BREAK-THRU  S 240, Goldschmidt GmbH as super-spreading agent.

[0052] For the treatment of plants, the titanium oxide dispersion A was adjusted to a concentration of 0.33% by weight (preparation A1) and 0.1% by weight of the preparation (preparation A2) with water. Further, an amount of super-spreading agent was added such that the concentration in both preparations (A1 and A2) was about 0.041% by weight. Both preparations A1 and A2 were sprayed onto the plants as aqueous solutions corresponding to a water demand o...

Abstract

Preparation containing at least one UV radiation absorbing metal oxide powder and at least one superspreading agent. Use of the preparation for the reduction of sunburn damage in useful plants.

Description

technical field [0001] The present invention relates to a preparation comprising UV ray absorbing metal oxide powder and a superspreading agent. The invention further relates to the preparation of said preparation and its use in reducing sunburn damage in plants. Background technique [0002] In Schmitz-Eiberger et al., Journal of Applied Botany, 77 (2003), pp. 75-81, the reduction of sunburn damage in useful plants by the use of zinc oxide is reported. The white zinc oxide is used here in the form of a lecithin dispersion. It was found that sunburn damage was only marginally reduced relative to untreated samples. At the same time, the disadvantageous fact is that the treated parts of the plants are covered with a layer of white zinc oxide, while the other plant parts are not covered. Contents of the invention [0003] It is an object of the present invention to provide a preparation by means of which sunburn damage on useful plants can be further reduced compared to th...
