BACKGROUND OF THE INVENTION The present invention relates to a plant stimulator or regulator including wood-based halogen compounds. Many compounds, such as auxin, auxinoids, kinins, gibberellins and ethylene retardants and abscisic acid retardants, have been successfully used in agriculture and forestry practice, although the biochemical nature of their activity is still a subject of various hybrids. [Audus JJ: Plant Science Mono-graphs, London-New York (1963); TureckaR. Ch., Polykarpova F. Ja .: Vegetatiinnoe Growth Growth with Stimulation of Rosta Stimulators, Moscow (1966)). Here, the growth regulators have spit structures [Appel P., Natr L .: Biochem. Physiol. 1976, 169; Wegler R .: Chemie der Pflanzenschutz und Schadlingsbekamffungsmittel, Band 4. Sprinter Verlag, Berlin-Heidelberg-New York (1977)). Succinic Acid Growth Growth Acid is known and an explanation of the biochemical effect of the effect of quantum biochemistry [Blagoveshchenskij A.V., Rachman R.R. Blagoveshchenskij A. V., Rachmanov R. R .: Biochemicheska-ja priroda povyšenija urozajnosti s pomosc-ju jantarnoj kisloty. Izdatelstvo Moskovsko-go Gosudarstvennogo Universiteta, Moscow (1970)], as well as organic sludges from anodic oxidation of aluminum, mainly containing succinic acid (Czechoslovakian Certificate No.229 411). Furthermore, maleic anhydride, maleic acid, its salts and esters (U.S. Pat. No. 228,318), as well as byproducts of cyclohexanone production by oxidation of cyclohexane (Czechoslovak Patent No. 220 936) and the like. The effective growth regulator is dichloroisobutyric acid and its salts (U.S. Pat. No. 2,823,232). The effective cytokinin is diphenylurea, which stimulates delenierastlinic cells [Bruce]. I., Zwar J. A.:Why. Roy Sec. Ser. B 163, 245 (1966)]. NDRpat. No. 143,346 (1980), as well as triacontanol, CH3 (CH2) .28CH2OH, which increases maize yield when sprayed on presses [Ries S.K., VentY .: Science 195, 1339 (1977)]. In turn, the growth of roots is stimulated by furcarboxylic acid derivatives [Krapirin G.A. et al .: Vseso-juz. Learn. Horses. Chim. Technol. Furan. So-Jed: Tezisy Dokl. 1978, pp. 104 (Riga)].

Said and other known plant growth promoters and regulators are of interest; they find their application in practice more difficult, and they are difficult to obtain in terms of both raw materials and potentially have undesirable side effects and thus still do not adequately address the needs of intensive agricultural and forestry production. And the range of potent stimulants and plant growth regulators, including woody plants, is expanding.

According to the present invention, the plant growth stimulator and / or growth regulator based mainly on organic halogen compounds consists of 30 to 60 wt. o-chloro-γ-butyrolactone, 30 to 50% by weight. % ajya-dichloro-γ-butyrolactone, 6 to 25 wt. α, α, γ-trichloro-γ-butyrolactone and 0.1 to 5 wt. γ-butyrolactone. The advantage of the stimulator and / or regulator of the invention according to the invention is the high bio-efficiency not only in the application of the grains, but also in the application of post-mercury with aqueous solutions, even by the concentration of the active substance of the order of only 10-5. wt. Furthermore, a long life, practically limited storage, whilst being wholesome. Last but not least, the technical availability and relatively easy formulation into pickling components of mineral fertilizers as well as polymers and copolymers of occluding seeds, grain and the like.

In addition, the preservative effect of the stimulator and / or growth regulator in the form of a liquid, slightly dispersed droplet, optionally in powder form, together with other known components, e.g., in the preparation and storage of seeds, can be utilized. More often, however, it is applied in the form of solutions, in particular dilute aqueous solutions with a concentration of 1. I.sub.3 to 1.10 ~ 5%, but also in the form of dispersions, emulsions, optionally together with other organic and anorganic substances, pesticides, fertilizers, especially liquid ap. It is suitable as a stimulant and / or plant restrictor, a non-woody plant. Further characteristics of the stimulator and / or growth regulator properties of the invention as well as other advantages thereof are apparent from the examples. Example 1

Spring experiments were carried out with spring yachts, aimed at studying the impact of the stimulators, respectively. morphegulators to grow barley crops.

Land conditions: brownish soil type - aluminum, pH in KC1 - 6.70; accessory P by Egner = 51.2 mg. kg-1; accessible K according to Schatschabela = 180.3mg. kg-1; plot area = 10 m2, repetition 4-fold; sowing of Rubín variety == 3.5 million germinating grains. ha-1. The plant spray is carried out in phase 5 of the growth stage of Feskesa or 400 dm 3 · h -1 for classification.

Spraying the stand before grading with an aqueous solution prepared from a 47.3 ° / w / w mixture. α-chloro-γ-butyrolactone, 37.4 wt% α, α-dichloro-γ-butyrolactone, 13.2% α, α, ω-tri-chloro-γ-butyrolactone and 2.1% wt. ω-butyrolactone with an aqueous solution concentration of 3.10 - 2% by weight. (variant 1) or 3.10-3pere. wt. (Option 3). The first variant is a control, i.e. the stand has not been treated with a morpho-regulator.

The results are summarized in Table 1.
