Description

Technical field

The technical solution relates to a composition which affects both the yields and the quality of cereal seeds, oilseeds and other crops.

Background Art

With the current technology of cultivation of crops, the expected yields of seeds and fruits often result from a number of different influences. Some of them are caused by the reduced vitality of the emerging plants, resulting in uneven growth. In overwintering plants, plant regeneration is more difficult, resulting in a reduced number of plants per unit area. Plants need to be fertilized especially with nitrogenous fertilizers in relatively high doses. The weakened plants do not utilize fully fertilizing components and losses are caused by the infiltration of nitrates into the lower layers. In deteriorated weather conditions, plants do not fully utilize fertilizer components to produce biomass, but store them in cells. After improving the weather conditions, the plants preferentially use the nutrients just received. Previously accepted and stored nutrients do not use and their presence in crops, especially nitrates, reduces the quality of harvested products.

In order to eliminate some of the undesirable effects, substances with morphegulatory effects can be used which can significantly reduce or even eliminate negatively acting factors. Substances with morphegulatory effects can also influence the better use of fertilizers and, at the appropriate stage of organogenesis, the deposition of assimilates into seeds, fruits and other storage organs. These problems can be solved by exogenous application of natural phytohormones. The use of these substances is expensive and is only used in gardening practice. The use of herbicides with an auxinoid effect may result in serious damage to the treated plants if the doses are not adhered to. Therefore, other substances are being sought, which may also be precursors of natural phytohormones, and after metabolization in plants, compounds with a stimulating effect are already produced. Some aminobenzoic acid derivatives may be auxin-type precursors of phytohormones. However, their stimulatory efficacy is low because subsequent metabolic processes inactivate them. Suitable combinations of aminobenzoic acids with phenolic substances have a stabilizing effect on the resulting metabolites and at the same time potentiate the desired stimulatory effect.

The essence of the technical solution

The aforementioned drawbacks are largely eliminated by means of yield and quality control of cereals, oilseeds and other crops according to the present invention. It is based on the fact that it contains a mixture of N (x-hydroxyphenyl) alkanamides of the general formula I, wherein R is hydrogen or alkyl of one to four carbons in the chain a and d determines the position of the OH group, and 2-, 3-, 4-aminobenzoic acids or a salt thereof in a weight ratio of 1: 100 to 100: 1

HIM

The aminobenzoic acids are preferably in the form of ammonium or alkali metal salts.

The most suitable form of application are solutions of the active substances in water, or in water-miscible solvents, or in the form of wettable powders, or water-soluble tablets.

In addition to the active ingredients, the application mixture contains auxiliary substances such as wetting agents (ionic and non-ionic surfactants and their mixtures), pH stabilizers (phosphates or salts of orgasic and polyhydric acids), droplet reducing agents on plants (sugars) and other polyhydroxy compounds), preservatives (salicylic benzoic acid, sorbic acid, 4-hydroxybenzoic acid esters) and frost-resistance enhancers (glycols, glycerol, etc.).

An important advantage of the composition according to the invention is that the active ingredients of the mixture as precursors and stabilizers of natural phytohormones are metabolised by plants biochemically to very effective phytohormones in the amount required by plants at a given stage of organogenesis. They also interact favorably with phytohormones, resulting in more intense growth. Plants are greener, nutrients are better used. The presence of the phenolic component in the mixture allows the formation of phenolic inhibitors of natural origin and thus indirectly affects the deposition of stocks into the seed.

Another advantage of the composition of the present invention is that the active ingredients of the component act on the plants in very low doses. The spray liquor is well absorbed by leaves and roots and does not harm the bees and fish. It can be combined not only with foliar fertilizers, but also with insecticides, fungicides and selective herbicides when applied in the form of waterborne ground and aerial sprayers.

The following examples illustrate, but do not limit, the effects of the composition of the present invention and the possibility of its application.

Examples of technical solutions

Example 1

A mixture of 3 parts by weight of N (4-hydroxyphenyl) butanamide, 2 parts by weight of 4-aminobenzoic acid, 4 parts of ammonia (25% NH ₃ ) and 10 parts of 2-propanol was diluted with water to a solution containing 10 mg of the above active substances in 1000 ml solution. The solution was treated with a plot of poppy seed (Gerlach variety) with an area of 10 m ² at a dose of 0.4 1 at the extension growth stage (DS 35-45). The control plot was then treated with water. The following parameters were harvested by seed: seed weight: 177.5 g (control 160.3 g), thousands of seeds (hereinafter HTS) 0.52 g (control 0.51 g), oil content in dry matter: 46.6% ( control 45.8%). The yield of seed of better quality is 10.7% higher.

Example 2

A mixture of active ingredients prepared from 3 wt. parts of N (4-hydroxyphenyl) ethanamide and 1 part of 2-aminobenzoic acid were dissolved in 50 parts of acetone and then diluted with water to a solution containing 2.0 mg of active ingredients in 1000 ml of solution. The solution was treated with a plot of winter oilseed rape (Pronto variety) with an area of 10 m ² at a dose of 0.4 l in the yellowish buds stage (DS 55-60). During the experiment it was found that plants treated with water alone had 25 to 30% less flowers. The harvested seed had the following parameters: seed weight 312.0 g (control 275.0 g), HTS 6.23 g (control 5.12 g), oil content in dry matter: 43.2% (control 41.5%). Seed yield is 13.5% higher.

Example 3

A mixture of 8 wt. parts of N (3-hydroxyphenyl) methanamide and 2 wt. 3-aminobenzoic acid was dissolved in 50 parts acetone. In a spring barley container experiment (Krystal variety), plants at the beginning of the sowing (DS 51) were treated with a solution containing 10 mg of active ingredients in 1000 mL of water at a dose of 400 L / ha. It was harvested (after conversion per tonne / ha) in experiment 4.1 and in control 3.95 t / ha. The yield increased by only 3.8%.

Example 4

3 wt. parts of N (4-hydroxyphenyl) ethanamide and 1 wt. A portion of 2-aminobenzoic acid at a total dose of 0.5 g / ha was dissolved in 200 L of water and applied to a winter wheat crop (Regina variety) for about 7 days prior to sowing. The vegetation after the treatment was greener. By measuring, it was found that the last leaf was also increased by about 10 to 15% over control. After harvest, it was found that the grain yield in the treated crop was 5.34 t / ha and 16% higher than in the control (4.60 t / ha). * ''

The resulting concentrate is applied at a rate of 0.1 l / ha in 400 l of water before flowering on a sunflower stand. The yield of seeds was 3.14 t / ha (control 2.73 t / ha), ie 15.2% higher.
