Abstract

The invention relates to a novel agent for inhibiting the transpiration in crops and willows based on a microbial phosphatide mixture, surfactants and organic solvents, which is used in a concentration of 0.05 to 5% in the aqueous emulsion. The new agent is in contrast to the mineral oil-based physiologically and toxicologically safe and readily biodegradable.

Description

This task is achieved according to the invention by mixtures which

20 to 80 Ma .-% of a microwave Phosohatidgemisches, 5 to 20 wt .-% surfactants and 15 to 70Ma .-% organic solvents

contain and the table diluted with water in a concentration of 0.05 to 5% in the aqueous emulsion used.

The microbial phosphatide mixtures are mixtures of phospholipids of microbial origin. They contain besides lecithin

and cephalin as the main components usually lower levels of other species-specific phospholipids and as

Accompanying substances or impurities specific oils, fatty acids and other fat accompanying substances. The proportion of phospholipids in

Microbial Phosphatidgemisch is 30 to 80Ma .-%, preferably 40 to 70Ma .-%. The microbial phosphatide mixtures, for example, in the processing of lipid extracts from the microbiological Futterhofeproduktion based on

Petroleum hydrocarbons as a by-product at low cost. Surfactants are mainly used conventional nonionic emulsifiers, primarily ethoxylated alkylphenols. If necessary, surfactant mixtures can also be used, for example nonionic and ionogenic Emulsifiers. As organic solvents are ketones or alcohols in the middle chain length range and hydrocarbons

preferred, for example, cyclohexanone or hexanols and xylene.

It has surprisingly been found that the agent according to the invention in comparison to the known agents based on mineral oil

even at lower use concentrations, a comparable or improved antiperspirant

Effectiveness shows. The agent of the invention is physiologically and toxicologically safe and without leaving toxic residues

easily biodegradable. Plant damage does not occur.

Due to the advantages of the agent according to the invention, the environmental impact is reduced and there are costs for

saved the treatment of the plants. A further advantage is that the uses of the inventive agent in forestry applications, for example in drinking water catchment areas, or in the horticultural sector are substantially enhanced, which is an important one over hydrocarbon-based agents

Represents progress. The therapeutic agent may be in the form of solutions or emulsions. The formulations are known in the art Made and applied. The invention will be further elucidated by the following examples. Exemplary embodiments example 1 Formulation of the agent according to the invention as emulsifiable concentrate:

Agent for inhibiting perspiration according to item 1, characterized in that the microbial Phosphatidgemisch 30 to 80 wt .-%, preferably 40 to 70Ma .-% phospholipids. 3. An antiperspirant agent according to item 1, characterized in that nonionic surfactants, preferably ethoxylated alkylphenols, are used. 4. means for inhibiting the transpiration according to item 1, characterized in that are used as organic solvents predominantly ketones or alcohols in the medium chain length range and hydrocarbons. Field of application of the invention The invention relates to an agent for inhibiting the transpiration of crops and woody plants, which can be used in forestry and horticulture, for example, in the preschooling of plant material, the use of cuttings and transplanting. Characteristic of the known technical solutions Forestry and horticulture often suffer from transpiration losses as a result of technological processes and extreme environmental conditions, which can lead to damage or even dying of crops. Influencing the water balance of crops, especially under dry stress or after transplanting, is therefore of great economic importance. Various measures are known for the reduction of transpiration loss. In addition to the use of mechanical means, such as the covering of the plants with plastic film, a dipping treatment of the plants or plant parts is carried out by special means. Their effect is based on the formation of a protective film on the plant and / or influencing the function of the necessary for the gas exchange stomata. An antiperspirant protective coating is, for example, agents based on oils or polymers, which may be of both natural and synthetic origin. As an oil-based antiperspirant are emulsifiable mineral oils (DE-OS 1767427), which can be modified by the addition of chlorinated paraffins (DD-WP 123052) or paraffin waxes (US-PS 3847641) known. DD-WP 229580 describes mineral oils compounded with biolipid extract as antiperspirant. The antiperspirant agents based on mineral oils have the disadvantage that, in addition to the effect of transpiration reduction certain Pflanzenschysiolo jische processes are negatively affected, which can be in a long-lasting growth depression or damage to plants kör, non. In addition, the mineral oils are poorly biodegradable and can lead to groundwater contamination, resulting in high environmental impact and use of e.g. in drinking water protected areas.
