Abstract

The invention relates to agents for influencing the Organverhaeltnis of crops, mainly in Maehdrusch- and root crops. The aim of the invention is to improve the proportion of economically relevant harvested products to the total biomass (harvest index). The invention has for its object to develop growth-regulating Mittl of drugs or drug components that cause due to syner gistic effects, the change in the organ ratio in favor of the main crop. The agents contain in addition to choline (I) and optionally ethanolamine (II) as further active ingredients salicylic acid or its derivatives (III) and / or 2-Chlorethylphosphonsaeure or their derivatives (IV) and other auxiliaries and Traegerstoffe. For root crops, the mixing ratio of I to II to III to IV is 1 to 0.1 to 1 to 0.4 to 1 to 0.1 to 0.5. In the case of omitting II, the ratios of I to III remain IV equal.

Means for influencing the organ ratio in crop plants

Field of application of the invention

The invention relates to agents for influencing the Qrganverhältnisses in crops, mainly in Mähdrush- and root crops.

Characteristic of the known technical solutions

It is known that combinations of 2,3-dichloroisobutyrate with chlorocholine chloride and / or 2,4-dichlorophenoxyacetic acid influence the leaf / root ratio in root crops, for example beet beets, in favor of the carcass, thereby enabling yield increases of these crops

 (DD-PS No. 145 880).

The disadvantages of this drug combination are primarily in the one-sided and therefore strongly dependent on the weather effect. Thus, when used under dry conditions, it may cause too much reduction. the leaf mass come, which affects the formation of substance unfavorable. The high proportion of chlorocholine chloride also brings toxicological problems in the utilization of the beet leaf. It is also known that ethanolamines or combinations of ethanolamines with phosphonic acids

and / or salicylic acid "or their derivatives and aluminum sulphate; or alum or phenoxyisobutyric acid derivatives improve the beet body yield without a large change in the organ ratio via increased water uptake (DD-FS 15 ~ 1 ACH- ) ♦ The application of these active substances or combinations of active substances is only successful the intended effects if the water balance of the plants is tense and, in addition, the change in the organ ratio is too low to allow effective water use «

Furthermore, agents for regulating growth and metabolic processes in plants are known in which active ingredient combinations of 2-chloroethylphosphonic acid and / or chlorocholine chloride and a dichlorophenoxyisobutyric acid derivative, for example 2,4-dichlorophenoxyisobutyric acid, are used (DD Pat. No. 136,209).

The disadvantages of these drug combinations are mainly in the uncertain effect. In addition, these agents only improve the water suitability and not the water utilization in terms of increased dry matter formation per unit of water consumed (WUE).

Perner is aware that dimethlysulfoxide with phenylbutazone or phenobarbital or ni-cetamide or metopirone increases the uranium stimulation productivity in cereals (DD-PS Hr. 126 141). An increase in this effect is possible by additions of effect-increasing agents to dimethylsulfoxide, such as acetylsalicylic acid, paraformaldehyde, 8-hydroxyquinoline or KH-ethylphosphonic acid (DD-PS Iir., 133,512),

Water-saving constitutional types in cereals are also induced by DD-PS No. 136,209 thereby

when the plants are treated with active ingredient combinations of 2-chloroethylphosphonic acid, chlorocholine chloride and / or 2,4-dichlorophenoxyisobutyric acid »

are in addition to the non-safe effect especially in the toxicological health of the used preparations and the complicated technical accessibility.

Aim of the invention;

The aim of the invention is to improve the proportion of economically relevant harvested products in the total biomass (Ernteinde.x).

presentation; the essence of the invention;

The object of the invention is to develop growth-stimulating agents from active substances or several active ingredient components which, owing to synergistic effects, effect the change of the organ ratio in favor of the main product and improve the yield-related utilization of water. The object is achieved according to the invention by treating the crops with solutions in addition to choline (I) and optionally ethanolamine or its derivatives (II) as further active ingredients salicylic acid or its derivatives (III) and / or 2-chloroethylphosphonic acid or its derivatives (IY) and conventional excipients and carriers.

Field trials with sugar beets

The experiments were carried out on loess sites. The middle combinations were sprayed as aqueous solutions ('tank mixes) on dry plant stocks, with the application immediately or three weeks after closure of the plant: was carried out "Each drug variant was tested at a plot size of 16.2 m in quadruple repetition. Sowing, care and fertilization were done in the usual way: and Wei3e to the agrotechnisch favorable dates. Subject of the manual grubbing of the beets, the leaf mass was determined and after washing the beets beet body. The determination of the Fasserausnutzung was based on the gross water supply (rainfall from 1 April to 30, September and the storage moisture to 100 cm depth) minus the soil moisture at harvest time, For the soil water content was determined immediately after harvest with the help of earth drills to 100 cm depth (10 samples per variant),
