PROPERTY REGULATING AGENT

The invention relates to a plant growth-5 regulating agent, the 3-isononyloxypropylammonium-t-methylphosphonate as an active substance in an amount of 0.2 to 95 mass% and solid or liquid carrier or filler material and optionally other auxiliary substances, preferably a surface-active substance Substance and / or 10 contains an adhesive in an amount up to 100 mass ^.

The process for the production of 3-isononyloxy-propyl-ammonium-methylphosphonate and its use as an active ingredient in fungicidal agents have been described in Hungarian Patent No. 15. 134,319. The patent does not mention the plant growth regulating activity of the above substance.

It was found that 3-isononyloxypropyl -ammonium-methylphosphonate in a suitable can «» Λ 20 root formation, growth, the development of the vegetative leaf surface, or the flower binding, binding and maturing of arable plants, e.g. B. wheat, corn, sugar beet and sunflower} from garden plants, e.g. 3. paprika, tomato, radish and 25 potatoes from Qbst trees, z. 3. Apple} from berry plants, e.g. B, currant and 'wine can regulate.

The agent according to the invention can be used in a concentration of 1 to 2000 ppm for regulating plant growth or for accelerating harvesting 30. The can to be used depends on the plant being treated, the purpose of the treatment, the phenological stage of the plant and the formulation of the agent.

Accordingly, the invention also relates to a treatment process for regulating plant growth and for accelerating the binding of flowers and harvests, characterized in that the seeds, plant plants and flowers in an amount of 1 to 2000 ppm active ingredient, or the soil of the plants before

Sowing in an amount of 0.001 to 5.0 g of active ingredient / m, or after planting or lowering by watering in an amount of 1 to 2000 ppm of active ingredient can be treated with an L agent which contains 3-isononyloxypropyl-ammonium 5 contains methylphosphonate al3 active ingredient in an amount of 0.2 to 95 masses ^ and solid or liquid carrier or filler material and optionally other auxiliary substances, preferably a surface-active substance and / or an adhesive in an amount up to 100 masses ^ 10.

Before being used in practice, the active substance according to the invention can be converted into an agent using solid or liquid carrier materials and optionally other auxiliaries, preferably surface-active substances 15 and adhesives.

Suitable carrier materials are organic or mineral, natural or synthetic substances which promote the adsorption or absorption of the active ingredient (for example water, methanol, glycerol, waxes, resins, 20 talc, etc.).

Suitable surface-active substances are ionic and / or nonionic emulsifying, dispersing or liablishing agents, preferably alkylaryl polyglycol ethers, fatty acid polyglycol esters, al3 adhesives. B. Polyvinylpyrrolidone, polyethylene glycol and carboxymethyl cellulose are used.

The agents according to the invention can be formulated as water-soluble concentrates (WSC), wettable powders (WP), dusts, emulsifiable concentrates (EC) and granules 30 (G).

The further details of the invention are evident from the following examples, which, however, do not limit the invention. In the examples,% 3-isononyloxypropylammonium methylphosphonate is referred to as 35 "BF ^ l".

Based on the results, it can be determined that the tubers treated with BF-51 can be sown a ’iyoche later without these 20 later sown plants being left behind in their development. This is particularly important in areas where the earlier seeds can be jeopardized by the adverse, cool spring weather.

10 pieces of vine with 10 buds each were soaked for 24 hours in a water-soluble WSC concentrate containing 10, 100 or 500 ppm of BF-51, then they were grown under plastic house pots on a humus sandy soil under greenhouse conditions.

After three months of breeding, the length of the sprouts developing on the speeches and the weight of the sprout and root after separation from the vines were determined. The data were averaged 35 for each treatment and the development of the - 10 -

Rung and. the root was compared to the control. The results are given in Table V.

The vine sprout development was accelerated by a concentration of 10 and 100 ppm of the 3F-51 90 20 WSC. Root development was accelerated by a concentration of 10, 100 and 500 ppm from the same WSC.

Example 14 25 The same amount of perlite impregnated with a Hvagland nutrient solution was placed in 4 plastic 2 ·· growing pots, each with an opening surface of 214 cm. Various cans of the BF-51 50 G granules described in Example 7 were evenly sprinkled on the surface of the pearlite and 10 cereal grains were sown in each pot.

In the four-leaf phase of the untreated control plants *, the plant length, the green weight and the quantity of root were measured (Table 7III), or the chlorophyll was determined in the tip of the second leaf of each plant (Table IX).

From the results, is it visible that all three active ingredients are essential to the development of the plants compared to the untreated control? accelerated.

* 5 The quotient plant height / green weight indicates, however, that BE-51 has a more favorable effect than the comparison substances. This shows that the habit of maize is not adversely affected by 3F-51, whereas 3 I develop disproportionately lean plants with an unfavorable habit due to the action of gibberellic acid.

The values of the chlorophyll determinations indicate that BE-51 has the most beneficial effect on the amount of chlorophyll formed in 1 g or in the whole green plant.

Example 16 * The root zone of tomato seedlings; was watered after planting with 0.1 liter of BP-51 90-20 WSC solution from a 250 ppm concentration.

The development was assessed after 6 'weeks. The results are shown in Table X.
