Description

The invention relates to agriculture, in particular to chemical plant protection products from pests and diseases, namely to combat cruciferous flea and fusarium flaxseed, and can be used to process its seeds before sowing.

In determining the prior art used publicly available information provided in all known sources of information.

There are no preparations for encrusting oilseed flax seeds against pests and diseases in the directory of pesticides and agrochemicals approved for use in the Russian Federation.

It is known to use a cruiser, SC against a complex of seedling pests for the treatment of rapeseed, mustard and sunflower seeds. The drug is very expensive to use, with a high consumption rate of 10 l / t and does not additionally have fungicidal properties.

The drug for the treatment of Chinook rapeseed, SC (100 + 100 g / l) against cruciferous flea on rape is approved for use. Its consumption rate is up to 20 l / t of seeds and high toxicity require the use of special hermetic seed treatment plants. The above facts, as well as inaccessibility and high cost, limit its use.

Known insecticide Furadan (LD ₅₀ - 5 mg / kg) for the treatment of rapeseed against cruciferous fleas, also included in the list of pesticides and agrochemicals approved for use in the Russian Federation, which is highly toxic and is allowed to be used only if there are special hermetic installations for processing of seeds, which are practically absent in collective and farm enterprises. In this regard, the use of these drugs in our country is extremely limited.

Closest to the claimed group of inventions, an analogue for the claimed composition (prototype) is the well-known INSECTICIDE COMPOSITION FOR PRESEEP TREATMENT OF SEEDS (according to the patent of the Russian Federation No. 2116029, A01N 57/16), which can be used to protect seedlings of agricultural crops from soil pests, to which include cruciferous fleas. The composition contains the fungicides TMTD (tetramethylthiuram disulfide) and APRON-35 (methyl ester N-2,6-dimethylphenyl) -N (2-methoxyacetylalanine), ACTELLIK insecticide, 50% ke, in which the active substance is -0,0-dimethyl -0- (2-diethylamino-6-methylpyrimidyl-4) thio phosphate, film former NaKMC, (sodium salt of carboxymethyl cellulose) and water in the following ratios of components, wt.%:

TMTD - 10.4-13.2; APRON-35 - 10.4-13.2; ACTELLIC - 6.7-15.6; NaKMC - 1.2-1.4; water is the rest.

There is also known a method of controlling pests of agricultural crops, described in the prototype, according to which sunflower seeds are treated with a flow rate of 10-15 l / t of seeds.

The disadvantage of the prototype is the lack of protection of seedlings of oil flax from pests and diseases, because the ACTELLIC insecticide does not provide reliable protection of oil flax plants from cruciferous fleas, and the TMTD fungicide is not effective for disinfecting oil flax seeds against diseases, and NaKMTs used in the prototype as an adhesive does not provide the necessary retention of the composition components on oil flax seeds and, in addition, its use (NaKMTs) is associated with some inconvenience in the preparation of a working solution for seed treatment, since it requires swelling of this substance and prolonged mixing. In addition, due to the presence of water in a known composition, as a necessary component of the composition, it complicates the technological process of processing flax seeds, worsening their flowability due to their mucus, which further complicates the process of sowing seeds in the field.

The present invention solves the problem of increasing the yield of oilseed flax seeds and expanding the range of products for controlling soil-borne pests, in particular cruciferous flea, as well as diseases of this crop.

The purpose of the invention is to give the claimed composition the property of a systemic insecticide, contact-intestinal action, a wide spectrum of action to provide a longer protective effect from soil-borne pests and the property of a systemic fungicide penetrating the vessels of oil flax plants and providing them with protection against vascular disease-fusariosis, as well as the property of a plant growth stimulant - to improve the sowing qualities of oil flax seeds and increase its productivity.

The technical result is achieved by the fact that the claimed insecticidal-fungicidal composition for controlling cruciferous flea and oil flax diseases by presowing seed treatment, including the insecticide, fungicide and adhesive, according to the invention further comprises a Silk immunomodulator, a complex of trace elements Aqua-mix and plant growth stimulator Humate Potassium and as an insecticide Tanrek, WRC (200 g / kg), as a fungicide But, VDG (500 g / kg) and as an adhesive - MiBAS in the following ratios of components, wt.%:

Tanrek 43.11-51.36;

But 2.39-3.01;

MiBAS 34.25-43.11;

Aquamix 1.72-2.15;

Potassium Humate 4.31-5.14

Silk 4.31-5.14;

The technical result is also achieved by the fact that in the claimed method of combating cruciferous flea and oil flax diseases by presowing treatment of seeds with a composition comprising an insecticide, fungicide, adhesive, according to the invention, the composition according to claim 1 at a dose of 5.84 l is used as a composition / t of seeds.

A comparative analysis of the claimed technical solutions with the prototype allows us to conclude that the claimed group of inventions differs from the prototype primarily in its qualitative composition: other than the prototype, Tanrek, fungicide - But, adhesive - MiBAS, and additional components - Aquamisk, Humate potassium and Silk, as well as a quantitative dose when processing this composition of seeds - 5.84 l / t of seeds.

Thus, the claimed technical solutions meet the patentability criterion of "novelty."

Studying the state of the art in the process of conducting a patent search on all types of information publicly available in the press, we found that the claimed technical solutions: insecticidal-fungicidal composition and method of controlling cruciferous flea and oil flax diseases for a person skilled in the art do not explicitly follow from known for the current level of technology.

The combined use of Tanrek, But, MiBAS, Aquamix, Potassium Humate and Silka creates not only a high protective effect against cruciferous fleas and, in addition, diseases, increases the sowing quality of seeds, promotes accelerated growth of the aerial mass and root system of plants, stimulates plant resistance to pathogens and other stress factors, but also enhances the fungicidal properties of the composition. The ratio of ingredients and the dose of the claimed composition are identified by our studies.

Therefore, we can conclude that the group of claimed inventions meets the patentability criterion of "Inventive step".

The claimed technical solutions meet the patentability criterion "Industrial applicability", because can be used in agriculture. Moreover, below will be described the means and methods by which it is possible to implement the claimed inventions in the form in which they are described in the claims. The invention is illustrated by the following examples.

Example 1. The preparation of insecticidal-fungicidal compositions with different ratios of components for seed treatment.

A "base" solution was prepared - a mixture consisting of 3 l of Tanrek, VRK (200 g / l), 0.14 kg But, VDG (500 g / kg), 2 l of MiBAS, 0.1 kg of Aquamix, 0.3 l Potassium humate and 0.3 L Silka. No water was added to the stock solution. The total consumption of the working solution was 5.84 l / t with the following ratios of components, wt.%:

Tanrek - 51.36

But - 2.39

MiBAS - 34.25

Aquamix - 2.15

Potassium Humate - 4.31

Silk - 4.31

In addition, the compositions were prepared according to the prototype and standard. The obtained formulations treated oilseed flax seeds in an incrustator, dividing the dosage of the applied composition into two parts and introducing them into the incrustator screw in two stages with thorough mixing of the seeds at the maximum unit speed. The processing and unloading of seeds from the machine 10 minutes

Example 2. Tests of the claimed insecticidal-fungicidal composition and method of controlling pests and diseases of oil flax, in particular cruciferous flea and fusarium, in the field (table 1 and table 2).

The inventive tool was tested at the central experimental base of VNIIMK, Krasnodar and under the conditions of the Federal State Unitary Enterprise "Berezanskoye", Korenovsky District, Krasnodar Territory in the active zone of cruciferous fleas with a population density of 20-24 individuals. 1 m ² , which is significantly higher than the economic threshold of harmfulness. Each experiment covered an area of 1 ha. Before sowing, oilseed flax seeds were treated with an insecticidal-fungicidal composition at the rate of 5.84 l / t of seeds.

RESEARCH METHODOLOGY

General agricultural cultivation. When seedlings appeared on these plots, all sprouted plants were scanned and the number of pests on these plants and a decrease in this number in variants with respect to the control were determined.

The effectiveness of processing oilseed flax seeds with various compositions was determined by the formula VNIIZR:

E = 100-V / A × 100,

where E is the efficiency, expressed as% reduction in the number of fleas relative to the control;

In - the number of fleas in the experiment on the day of accounting;

A is the number of fleas in the control on the day of recording.

Disease prevalence (P) is calculated using the formula P = n / N · 100%

$$P=\frac{n}{N}\cdot \mathrm{one\; hundred}\%$$

where N is the total number of accounting plants;

n is the number of plants affected by diseases.

Biological effectiveness is calculated by the formula:

$$C=\frac{\mathrm{one\; hundred}\left(a-\mathrm{at}\right)}{a}$$

where C is the biological efficiency,%;

a - the degree of development or the number of diseased plants in the control;

c - the degree of development or the number of diseased plants in the treated area.

Analysis of the obtained data allows us to conclude about the advantages of the claimed ratios of the components of the claimed composition in comparison with the prototype. Moreover, the effectiveness of the claimed composition in the optimal ratios of its components increases relative to the prototype by 27% and the standard by 35% and amounts to 93% (table 1). The inventive insecticidal-fungicidal composition in its biological effectiveness exceeds the action of the prototype 1.4 times and the action of the standard 1.6 times.

As can be seen from table 3, the yield of oilseed flax during seed treatment by the claimed composition increases relative to the control by 0.14 t / ha and is higher than the level of the prototype, exceeding it by 0.09 t / ha.

A study of the influence of the claimed composition on the yield of oil flax in the field production conditions of OCX "Berezanskoye" in the Korenovsky district, Krasnodar Territory revealed an increase in yield of 0.15 t / ha relative to control (table 3) on an area of 4 ha.

Table 3 Economic efficiency of insecticidal-fungicidal compounds, grade of oil flax VNIIMK 620 Option Consumption rate of composition, l / t Seed productivity, t / ha ± to control, t / ha 2009 year 2010 year 2011 year average over years 1.

The claimed composition 5.84 1.45 1.10 1.00 1.18 +0.14

So, from the analysis of the data given in tables 1-5, it can be seen that the new qualitative composition of the claimed drug, including Tanrek as an insecticide, But, as a fungicide, Mi-BAS as an adhesive, and additionally Aquamix, Humate Potassium and Silk in the claimed ratios and with the claimed consumption rate of the claimed composition, identified by our research, when treating them with seeds, it provides effective and reliable protection of oilseed flax from cruciferous fleas and fusarium due to the high degree of composition retention on the seed flax cultivars during their processing, enhancing the protective properties of plants in relation to stressful and adverse environmental factors, increasing plant immunity in relation to diseases and, as a result, to increasing the yield of oil flax seeds.

The calculation of the economic efficiency of the use of the claimed composition and method of controlling cruciferous flea and oil flax diseases in the production environment of FSUE Berezanskoye showed a net income of 9875.09 rubles / ha, the level of profitability was almost 22.5 times higher than when using the prototype ( table 5).

Thus, the claimed insecticidal-fungicidal composition and method of controlling cruciferous flea and oil flax diseases, including treating the seeds with this composition at the declared rate of consumption of the composition (table 1), can effectively protect seedlings of oil flax plants from damage by cruciferous flea, disease damage and get income per ruble of expenses is more than 11.9 times more than the standard-cruiser (table 5).

Based on the foregoing, we can conclude that the claimed group of inventions can more effectively protect seedlings of oilseed flax from pests, in particular cruciferous fleas, and diseases, in particular from fusariosis, and thereby increase the yield of seeds of this culture, as well as expand the range of tools for controlling soil-borne pests, i.e. achieve the goal and solve the problem.
