Description

DESCRIPTION

The invention relates to a plant growth regulating agent, the 3-isononyloxypropylammonium-methyl-phosphonate as an active ingredient in an amount of 0.2 to 95% by mass and solid or liquid carrier and filler material and optionally other auxiliaries, preferably a surface-active substance and / or contains an adhesive in an amount up to 100% by mass.

The process for the preparation of 3-isononyloxypropylammonium methylphosphonate and its use as an active ingredient in fungicidal agents have been described in Hungarian Patent No. 184 319. In this patent the plant growth regulating effect of the above substance is not mentioned.

It has been found that 3-isononyloxypropylammonium methylphosphonate in a suitable can the root formation, the growth, the development of the vegetative foliage surface, or the flower binding, harvest binding and harvest maturity of arable plants, e.g. B. wheat, corn, sugar beet and sunflower; of garden plants, e.g. Bell pepper, tomato, radish and potato; fruit trees, e.g. Apple; of berry plants, e.g. Can regulate currant and wine.

The agent according to the invention is used to accelerate harvesting. 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 method for regulating plant growth, preferably for increasing the flower and harvest yield. The method consists in that the seeds, plant parts of the vegetative pre-planting and flowers in an amount of 1 to 2000 ppm of active ingredient, or the soil of the plants before sowing in an amount of active ingredient of 0.001 to 5.0 g / m2,

or after planting or lowering in an amount of active ingredient from 1 to 2000 ppm, are treated with an agent by watering, the 3-isononyloxypropylammonium methylphosphonate as active ingredient in an amount of 0.2 to 95% by mass and solid or liquid carrier or filler material and optionally contains other auxiliaries, preferably a surface-active substance and / or an adhesive in an amount up to 100% by mass.

Suitable carrier materials are organic or mineral, natural or synthetic substances that promote the adsorption or absorption of the active substance (e.g. water, methanol, glycerin, waxes, resins, talc, etc.). 5 Ionic and / or nonionic emulsifying, dispersing or wetting agents, preferably alkylaryl polyglycol ether, fatty acid polyglycol ester, can be used as surface-active substances, e.g. Polyvinylpyrrolidone, polyethylene glycol and carboxymethyl cellulose can be used. The agents according to the invention can be formulated as water-soluble concentrates (WSC), wettable powders (WP), dusts, emulsifiable concentrates (EC) and granules (G).

The further details of the invention are evident from the 15 examples which follow, but which do not limit the invention. In the examples, 3-isononyloxypropylammonium methylphosphonate is referred to as “BF-51”.

Based on the results, it can be determined

that the tubers treated with BF-51 can be sown one week later without the plants that were sown later 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.

Example 13

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

After three months of cultivation, the length of the shoots developing on the blind vines and the weight of the shoots and the root after separation from the vines were determined. The data were averaged for each treatment and the development of the shoot and the root was compared with the control. The results 20 are given in Table V.

The shoot development of the grapevine was accelerated by a concentration of 10 and 100 ppm of the BF-51 90 WSC. Root development was accelerated by a concentration of 10,100 and 500 ppm from the same WSC.

Example 14

The same amount of perlite soaked in an Hvagland nutrient solution was placed in 4 plastic growing pots, each with an opening area of 214 cm2. Various cans of the BF-51 50 G granulate described in Example 7 were evenly sprinkled on the surface of the perlite and 10 cereal grains were sown in each pot.

After the beginning of the rising, the rate of rising was continuously assessed for each treatment until the

35% of control rising to 90% (Table VI). Furthermore, the germination percentage, the sprout length, the green weight and the amount of roots in the four-leaf phase of the control plants were rated. The results are shown in Table VII.

It is evident from the results that a) the treatments have accelerated the rate of plant emergence; and b) both the plant height and the green weight of the plants have been significantly increased compared to the control.

Example 15

In seed pots sown with maize (5 plants / pot), 65 after spraying (post-emergent) was sprayed with a BF-51 or gibberellic acid or 3-indolylacetic acid solution of 250 or 500 ppm concentration. In the four-leaf phase of the untreated control plants, the plant

The total chlorophyll content of the total green weight = Ch (a + b) x average value of the green weight of a plant

It is evident from the results that all three active substances significantly accelerated the development of the plants compared to the untreated control.

However, the quotient plant height / green weight indicates that BF-51 has a more favorable effect than the comparison substances. It shows that the habit of maize is not adversely affected by BF-51, while disproportionately lean plants with an unfavorable habit develop due to the action of gibberellic acid.

40 The values of the chlorophyll determinations indicate

that BF-51 has the most beneficial effect on the amount of chlorophyll formed in 1 g or in the whole green plant.

Example 16

45 After planting, the root zone of tomato seedlings was watered with a concentration of 250 ppm each with 0.1 liter of BF-51 90 WSC solution. The development was assessed after 6 weeks. The results are shown in Table X.

The results of the measurements indicate that the ripening processes of the apple treated with BF-51 are slowed down, which makes it possible for an apple that is read later to reach the memory in an optimal reading or storage ripening phase, which is a prerequisite for the favorable Is storability.

The information in Table XIII proves that the shelf life of the apple treated with BF-51 is favorable despite the late harvest and storage.
