Description

BACKGROUND OF THE INVENTION The present invention relates to a powder and suspension composition for cultivating crop plants, improving their drought and frost tolerance.

Dolomite, which, in addition to its well-known calcium and magnesium content, contains trace elements in many other minerals, has an effect on plant growth, drought and frost resistance when absorbed in foliage of plants. These effects of dolomite have not been known so far. The subject of the Hungarian patent number 175578 is its application as dolomite slurry. It is an important discovery of this patent that dolomite, used as a powder or suspension composition, is able to penetrate the waxy layer of the leaf and then hydrolyze and thereby dissolve into the cellular fluid. The effect of dolomite absorbed into the plant has been described in the above invention only in terms of yielding additional fruits.

Extensive studies and experiments have been conducted on the absorption and biological activity of dolomite. Its effect on grapes was studied by solo analysis (Institute of Viticulture and Wine Research, 1979), instrumental measurements and autoradiographic radiography (Gödöllő University of Agricultural Sciences, 1980). The effect on apples was examined in apple orchards (Gödöllő University of Agriculture, Department of Agricultural Chemistry, 1981-82). The effects of dolomite on a total of 16 different crop plants were monitored in field trials at 57 sites (Center for Plant Protection and Agrochemistry, Ministry of Agriculture and Food, 1979-80).

During the experiments not only plant species were different, but soil quality was also variable and several dolomite concentrations were examined.

The application of dolomite has always had an effect on the plant, although in some cases it has a negative effect due to overdose.

We have found that dolomite not only affects the content and quantity, but also drought and frost tolerance and has a dwarfing effect.

Advantageous effects are not expected for a person skilled in the art due to the effect of dolomite-containing foliar fertilizers on product volume and yield, since these properties are related to different areas of plant metabolism.

The above effects can be achieved by applying 0.1 to 10%, preferably 0.2 to 3.0%, of the composition at 3 to 15, preferably 3 to 5 kg / ha.

It is possible to determine the optimal amount of dolomite for each plant species according to the expert's knowledge.

The quality of dolomite used for our investigations is as follows:

MgO min. 21%

CaO min 29%

Ah03 max. 0.05% FezOa INAX. 0.025% TiO max. 0.05% SiO max. 0.32% Acid insoluble max. 42% Nazo max. 0.37% KZO then max. 0.13%

Trace elements: Sr max. 0.007% Cu max. 0.001% Zn max. 0.01% B max. 0.09% Mn max. 0.005%

Dolomite contains the following elements in trace amounts:

Li, Mn, As, Pb, Ca, Sn, Mg, In, Ag, N, Co, Cr, V

Dolomite alone is used either as a powder or as a suspension formulation.

SUMMARY OF THE INVENTION An object of the present invention is to provide a powder and suspension composition suitable for seeding, drought and frost resistance of crop plants.

The powder composition of the invention comprises 90-95% by weight of dolomite powder having a particle size of up to 30 microns and 5-10% by weight of sulphite lye powder and optionally at least 0.2% by weight of a plant protection product or a mixture thereof.

The suspension composition contains from 0.1 to 10% by weight of dolomite powder and from 5 to 10% by weight of sulphite lye powder and thereafter as a liquid water and optionally at least 0.2% by weight of a plant protection product or a mixture thereof.

The fine powder below 30 microns is erauled by the floating material and thus can be sprayed onto the plants in suspension without settling, or the powder composition does not lump during storage.

The composition is applied at the appropriate time and in the amount appropriate to the culture to be treated.

In order to take advantage of the dwarfing effect, treatment should be done early in the vegetation, at the latest until flowering; treatment for late frost, post-loreal discharge or frost risk is effective in improving frost tolerance.

The dolomite-containing composition may, if desired, also be used in combination with pesticides, such as herbicides and / or fungicides and / or insecticides.

The effect of dolomite on plant growth was studied on bean and lawn grass. Bercema CCC (a preparation of chlormequat chloride, manufactured by VEB Berlin Chemie, NDK), a known growth inhibitory regulator for dwarfism, was used as a control.

The effect of treatment is expressed as the percentage of change in the untreated control.

As shown in the table, dolomite treatment had a turbidity effect at each dose applied. The reduction in plant height compared to untreated control at a dose of 10% was 25.6%. This value is equivalent to the effect achieved with Bercema CCC. At 15% of the dose, the dwarfing effect is more pronounced, but the plant has a reduced fading 5-10 days after treatment and a phytotoxic effect after 20 days.

A 20% reduction in tool length has already had a significant economic impact, for example in reducing grain tilt. In Hungary, the damage caused by grain fall is estimated at 12% per year on average. With this in mind, hundreds of thousands of tons of cereal crop could be saved by crushing grain according to the invention. It is noted that the reduction in the length of the gut, based on the known effect of dolomite, leads to an increase in the intestinal content.

From the data in the table it can be seen that dolomite produces a 10% dose reduction of 30% with the same effect as 0.3% Bercema CCC. Even at 15% dolomite dose when applied to lawn grass

It has a phytotoxic effect and a growth-reducing effect of 44.4%.

A change proportional to the variation in height was observed in the study of the grass weights. Our results are shown in Annex III. table.

The experiment with lawn grass shows the role that the composition of the invention may play in the care of lawn surfaces. As growth slows, the frequency of shearing can be reduced. Dolomite-containing compositions can also be used to dwarf ornamental plants and houseplants.

It is of great importance that dolomite or a composition containing dolomite can be substituted for the active ingredient chlormequat chloride. This is important not only because of the significant cost difference between these formulations, but also its environmental importance, since dolomite is not a burden on the environment. While CCC has been authorized for environmental purposes only for seed production, dolomite-containing preparations can be used without restriction on any plant. This also allows their combined use with pesticides.

Improved drought tolerance of plants is associated with thickening of skin tissue. 55 changes of this during dolomite treatment are shown in Table IV. and Table V.

The respiratory depressant effect of dolomite and its reduction in assimilation through en65 not only compensates for drought, but also contributes to respiratory depression by spraying 3-10% dolomite in the early stages of vegetation prior to emergence, extending the winter dormancy of 5 plants . Prevents critical winter after-frost damage.

This is particularly important for stone trees and grapes. So far, attempts have been made to prevent winter after-frost by breeding 10 new breeds.

In frosty areas it is advisable to prepare the vegetation for winter frosts. This is achieved by spraying 3-5% dolomite after harvest. The vegetation is more resistant to winter frosts due to its charge with Ca and Mg ions.

You can protect yourself against frost damage by using a dolomite-containing preparation up to 24 hours before the indicated frost risk. The reason for this is the very rapid absorption of dolo- mite. Due to the absorption of Mg, the water loss process of the plant starts immediately and approx. After 15 hours, the balance will be restored.

As described above, by spraying 0.1-10%, in particular 0.2-3.0%, dolomite, we can avoid frost damage according to a 24-hour forecast.

Our studies on drought tolerance were conducted in apple orchards. 0.5% to 30

After 3 months of total drought on apple trees sprayed with a slurry of suspension, the loading of the buds was as extensive and advanced as, in the opinion of practitioners, under normal conditions at the time of spring flowering.
