Description

The invention relates to agriculture, in particular to chemical plant protection products from pests and diseases, for example, from cruciferous fleas and Fusarium, and can be used to treat seeds of winter and spring rape, Sarepta mustard before sowing.

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

It is known to use a cruiser, SC against a complex of seedling pests for treating seeds of sugar beets and sunflowers. The drug is very expensive to use, with a high consumption rate of 10-14 l / t and does not additionally have fungicidal properties.

The drug for the treatment of chinook rape seeds, SC (200 g / l) against cruciferous fleas based on imidacloprid + beta - cyfluthrin (LD50 = 50 mg / kg) is approved for use. Its consumption rates of up to 20 l / t - 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.

For the treatment of rapeseed against cruciferous fleas, the drug furadan (LD ₅₀ - 5 mg / kg), which is highly toxic and can only be used with special hermetic seed treatment plants, is also included in the list of pesticides and agrochemicals approved for use in the Russian Federation which are practically absent in collective and farm enterprises. In this regard, the use of these drugs in our country is extremely limited.

The closest analogue to the claimed composition is the well-known INSECTICIDE COMPOSITION FOR PRESEEP TREATMENT OF SEEDS (according to the patent of the Russian Federation No. 2116029, A01N 57/16), including the fungicides TMTD (tetramethylthiuramdisulfide), APRON-35 (methyl ether N-2,6-dimethylmethyl ether) (2-methoxyacetylalanine), ACTELLIK insecticide, 50% ke, in which the active substance is 0,0-dimethyl-0- (2-diethylamino-6-methylpyrimidyl-4) thiophosphate, NaKMC film former, (carboxymethyl cellulose sodium salt) 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: a known insecticidal composition was tested on a field with a population density of wireworms of 8-10 copies per 1 m ² by pre-sowing treatment of sunflower seeds with the known above composition 14 days before sowing. After the emergence of sunflower seedlings, the deaths of wireworms and plants damaged by them were carried out by soil excavation to the depth of seed placement at two linear meters of each row, which showed the effectiveness of the known composition for protecting sunflower seedlings from damage by wireworms.

The disadvantages of the prototype is the lack of protection of seedlings of cruciferous crops from pests and diseases, because ACTELLIC insecticide in the recommended consumption rate of 3-4 l / t does not provide reliable protection of rapeseed plants from cruciferous fleas. Recommended in the known invention, the rate of application of the fungicide TMTD 1.5-2.0 kg / t is not effective for disinfection of rapeseed from diseases. A very significant drawback is the use of NaKMC as an adhesive, the retention of which on oilseeds is significantly lower than other adhesives, and its use 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.

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

The purpose of the invention is to increase the protection efficiency of seedlings of crops, in particular cruciferous (winter and spring rape, mustard mustard), from pests - cruciferous fleas and diseases by increasing the germination of seeds and enhancing the fungicidal properties of the composition.

The technical result is achieved by the fact that the known insecticidal composition for presowing treatment of seeds, including the insecticide 0,0-dimethyl-0- (2-diethylamino-6-methylpyrimidyl-4) thiophosphate (actellic), the fungicide tetramethylthiuramdisulfide (TMTD), according to the invention additionally contains microelement biologically active composition MiBAS and plant growth stimulator - Silk in the following ratios of components, wt.%:

Actellic 17.4-40.0 TMTD 25.6-33.3 MiBAS 16.7-20.0 Silk 0.56-0.67 Water  rest

The technical result is also achieved by the fact that in the known method of controlling pests of agricultural crops by pre-sowing seed treatment with a composition comprising the ACTELLIK insecticide and the fungicide TMTD, according to the invention, the composition additionally contains a microelement biologically active composition MiBAS and a plant growth stimulator SILK in the above proportions components for seed treatment at a dose of 15 l / t of seeds.

A comparative analysis of the claimed technical solutions with the prototype allows us to conclude that the claimed insecticidal-fungicidal composition and method of combating pests and diseases of agricultural crops differ from the prototype in that the claimed composition, which is treated with seeds before sowing to control pests and agricultural diseases cultures, in addition to ACTELLIKA and TMTD additionally contains two ingredients (MiBAS and SILK) in certain proportions with the first and a certain consumption rate of the claimed composition during processing and m seeds, i.e. the claimed invention differs from the prototype in qualitative and quantitative compositions: it contains higher dosages of TMTD and Actellik, which contribute to more effective protection of rapeseed from cruciferous fleas and fusarium, and additionally contains MiBAS (microelement biologically active composition) containing microelements: copper, zinc, cobalt and having a higher degree of retention on the seeds of cruciferous crops compared with the film former NaKMTs used in the prototype, and Silk-drug that regulates growth and p zvitie plants and enhance their immunity to disease, in a specific ratio to aktellik and TMTD, and determine the composition of the flow rate in the processing of their seeds. Thus, the claimed technical solutions meet the patentability criterion of "novelty."

Studying the prior art in the process of conducting a patent search on all types of information generally available in the press, we found that the claimed technical solutions: insecticidal-fungicidal composition and method; the control of pests and diseases of crops for a person skilled in the art does not explicitly follow from the currently known prior art. The combined use of Actellik, TMTD, MiBAS and Silka creates not only a high protective effect against cruciferous fleas and, in addition, diseases, increases the sowing quality of seeds, stimulates plant resistance to pathogens, but also enhances the fungicidal properties of the composition. The ratio of ingredients and the dose of the claimed drug have been identified by our research. 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 6 L of Actellic CE (500 g / L), 5 L of TMTD, VSK (400 g / L), 3 L of MiBAS and 0.1 L of Silk. 0.9 liters of water was added to the stock solution. The total consumption of the working solution was 15 l / t with the following ratios of components, wt.%:

Actellik - 40.0

TMTD - 33.3

MiBAS - 20.0

Silk - 0.67

Water - the rest

In addition, the compositions were prepared according to the prototype and standard. The resulting compositions were treated with rapeseed in a grain dressing machine. Processing and unloading of seeds from the machine 45 sec.

Example 2. Testing of the claimed insecticidal-fungicidal composition and method of controlling pests and diseases of crops, 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 OCX "Berezansky", Korenovsky district, Krasnodar Territory in the zone of active operation of cruciferous fleas with a population density of 5-6 specimens per 1 meter, which is higher than the economic threshold of harmfulness. Each experiment covered an area of 1 ha. Before sowing, rapeseed seeds were treated with an insecticidal-fungicidal composition at the rate of 15 l / t of seeds.

General agricultural cultivation. When seedlings appeared on these plots, all sprouted plants were scanned and the percentage of plant damage by the pest was determined in relation to the number of sprouted plants. The effectiveness of each treatment was calculated 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.

Analysis of the obtained data allows us to conclude about the advantages of the claimed ratios of the components of the composition (options 4) in comparison with the prototype (option 3). Moreover, the effectiveness of the claimed composition in the optimal ratios of its components increases relative to the prototype by 16% and the standard by 26% and amounts to 83% (table 1).

The inventive insecticidal-fungicidal composition in its biological effectiveness exceeds the action of the prototype 1.2 times and the effect of the standard 1.5 times.

As can be seen from table 3, the yield of spring rape during seed treatment by the claimed composition increases relative to the control by 0.36 t / ha and is higher than the level of the prototype, exceeding it by 0.13 t / ha.

A study of the influence of the claimed composition on the yield of spring rape in the field production conditions of the OCX "Berezanskoye" of the Korenovsky District, Krasnodar Territory revealed an increase in yield by 0.33 t / ha relative to control (table 4) in areas of 3 ha.

The calculation of the economic efficiency of the application of the claimed composition and method of controlling cruciferous fleas and diseases in the production environment of OCX Berezanskoye showed a net income of 2749.11 rubles / ha and the level of profitability was almost 4.5 times higher than when using the prototype (table 5 )

Thus, the claimed insecticidal-fungicidal composition and method of controlling pests and diseases of agricultural crops, including treating the seeds with this composition at the ratios of the components specified in option 4 of table 1, can effectively protect the seedlings of plants from damage by cruciferous flea beetles, disease damage and receive income on 1 ruble of expenses is more than 1.5 times more than the standard-furadan (table 5).

Based on the foregoing, we can conclude that the claimed group of inventions can more effectively protect shoots of cruciferous crops, in particular rapeseed, from pests, in particular from cruciferous fleas, and diseases, in particular from fusarium, and thereby increase seed yield these crops, as well as expanding the range of tools for combating tillage pests, i.e. achieve the goal and solve the problem.
