Description

The invention relates to agriculture, in particular to chemical plant protection products from pests, in particular from wireworms, and can be used to treat sunflower seeds before sowing.

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

Known use of the drug semaphore, TPS (200 g / l) containing the active substance bifentrin, and a method for its use for dressing sunflower seeds against wireworms. However, this isecticide is ineffective against wireworms, since it has the most pronounced repellent properties, which is insufficient to protect seedlings from such a dangerous and numerous pest as wireworm (Handbook of pesticides and agrochemicals approved for use in the Russian Federation / Handbook. - M: - 2008. - p.30).

The closest analogue (prototype) for the claimed composition is the well-known - INSECTICID COMPOSITION FOR PRESEEP TREATMENT OF SEEDS (according to the patent of the Russian Federation No. 2116029, А01N 57/16), including fungicides TMTD (tetramethylthiuramdisulfide); APRON-35 (methyl ester N-2,6-dimepilphenyl) -N (2-methoxyacetylalanine), insecticide acteplik, 50% ke (synonyms: pyrimiphosmethyl, gloss), active ingredient 0,0-dimethyl-o- (2-diethylamino-6-methylpyrimidyl-4 thiophosphate), NaHMC hyghenic formant, (sodium salt of carboxymethyl cellulose) and water in the following ratios of components, wt.%: TMHD 10.4-13.2; apron-35 10.4-13.2; Actellik - 6.7-15.6; NaKMTS - 12-1.4; water is the rest.

There is a known method of controlling wireworms described in the prototype: a known insecticidal composition was tested in the Krasnodar Territory on a field with a population density of wireworms of 8-10 copies per 1 square meter by pre-sowing treatment of sunflower seeds with the known above composition 14 days before sowing. After the emergence of sunflower seedlings, the death of wireworms and plants damaged by them was 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 disadvantage of the prototype is not sufficiently reliable protection of sunflower plants from wireworms, the high cost of the composition and its insufficient environmental safety.

The present invention solves the problem of increasing the yield of sunflower and expanding the arsenal of tools for controlling soil pests, in particular wireworms.

The purpose of the invention is to provide the plant with a faster achievement of such a development phase in which its roots have time to become so coarse that they do not allow wireworms to feed on their juices, and at the same time use an environmentally safer and more economical means for pre-sowing seed treatment.

The technical result is achieved by the fact that the known insecticidal composition for controlling pests of crops, including the fungicide TMTD - tetramethylthiuram disulfide, the insecticide, according to the invention additionally contains MiBAS - a microelement biologically active composition and SILK - plant growth stimulator and immunomodulator), and DIAZINO as an insecticide CE (600 g / l) in the following ratio of components, wt.%: TMTD - 33.3; DIAZINON - 25.0; MiBAS - 25.0; SILK - 0.83, water - the rest.

The technical result is also achieved by the fact that in the known method of controlling wireworms by treating seeds with a composition comprising TMTD fungicide, an insecticide, according to the invention, the composition additionally contains MiBAS, a microelement biologically active composition and SILK, a plant growth stimulator and immunomodulator, and DIAZINON as an insecticide CE (600 g / l) in the above ratio for seed treatment at a dose of 10-15 l / t of seeds.

A comparative analysis of the claimed technical solutions with the prototype allows us to conclude that the claimed insecticidal composition and method of controlling pests of agricultural crops differ from the prototype in qualitative and quantitative compositions: additional components (MiBAS, Silk), another amount of the component contained in the prototype (TMTD : in the prototype 10.4-13.2, and in the inventive composition - 33.3 wt.%). Thus, the claimed technical solutions meet the patentability criterion of "NOVELTY."

Studying the prior art in the process of conducting a patent search: for all types of information publicly available in the press, we found that the claimed technical solutions: insecticidal composition and method of controlling pests of crops for a specialist in this field of technology do not explicitly follow from the currently existing prior art. It should be noted that when creating the proposed composition, we proceeded not only from the availability and relative cheapness of the domestic drug - diazinon, but also from its relationship to the class of organophosphorus insecticides. Interest in the latter is determined by their low persistence and high selectivity, which excludes accumulation in the soil. As a result of our studies, a high efficiency of the action of diazinone CE (600 g / l) together with TMTD, VSK (400 g / l), MiBAS and Silk in the claimed ratio of components was revealed: damage to sunflower plants by wireworms during seed treatment with the proposed composition is reduced by 90.9 %, compared with plant damage when using only TPS semaphore (200 g / l) standard, as well as in comparison with the prototype. 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

Preparation of insecticidal composition with various ratios of components for the processing of sunflower seeds. A “base” solution-mixture was prepared consisting of 3 L of diazinon, CE (600 g / L), 4 L of TMTD, VSK (400 g / L), 3 L of MiBAS, 0.1 L of silica and 1.9 L of water. The total volume of the solution is 12 l / t, with the following ratio of components, wt.%: TMTD - 33.3; DIAZINON - 25.0; MiBAS - 25.0; SILK - 0.83; WATER - the rest.

Diazinon is the active principle in the insecticidal composition, the actions of the remaining components are aimed at ensuring, by the combination of microelements, a growth regulator and an immunomodulator, that the plant more quickly reaches its development phase, in which the root and root parts of the plants are so coarsened that they do not allow wireworms to feed their juices.

The resulting solutions were treated with sunflower seeds in a grain dressing machine. The processing and unloading of seeds from the machine is 45 s.

Example 2

Testing of the claimed insecticidal composition and method of controlling pests of crops, in particular wireworms, in the field.

The inventive tool is tested in the conditions of the SPK "Kolkhoz named after V.I. Lenin", Novokubansky district, Krasnodar Territory, in the zone of active action of wireworms with a population density of 15 copies per 1 m ² . Each experiment covered an area of 1 ha. Before sowing, sunflower seeds were treated with insecticidal compositions at the rate of 10-15 l / t of seeds.

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

E = 100-V / A × 100,

where E is the effectiveness in% of the reduction in density or damage to plants relative to the control,

In - the number of pests (damage) in the experiment on the day of registration,

A - the number of pests (plant damage) in the control on the day of registration.

Table 1
The effectiveness of the protection of sunflower seedlings from wireworms when treating seeds with an insecticidal composition, grade R-453, CEB VNIIMK, Krasnodar No. Option Consumption rate of composition, l / t Damage to plants,% Biological effectiveness,% on average for 2006-2008 2006 year 2007 year 2008 year one The control without treatment 80.0 70.6 87.5 - 2 Semaphore, TPN (200 g / l) (standard) 2.5 40,0 29.8 30,0 59.0 3 Prototype 10.0 10.0 9.0 12,4 87.0 four The inventive composition 12.0 7.5 6.2 8.2 90.9

Analysis of the obtained data allows us to conclude about the advantages of the claimed ratios of the components of the composition (option 4) in comparison with the standard semaphore (option 2) and the prototype (option 3). Moreover, the biological effectiveness of the claimed composition in the optimal ratios of its components increases relative to the semaphore (200 g / l) and amounts to 90.9% (Table 1).

The inventive insecticidal composition in option 4 exceeds the action of the standard by 1.5 times, and the action of the prototype by 1.04 times. As can be seen from table 2, the sunflower crop during seed treatment by the claimed composition increases relative to the control by 0.35 t / ha, 0.16 t / ha above the prototype and 0.19 t / ha above the standard.

A study of the influence of the claimed composition on the yield of sunflower under field conditions revealed an increase in yield of 0.30 t / ha relative to control (table 3) and 0.11 t / ha above the prototype on an area of 5 ha.

The calculation of the economic efficiency of the application of the claimed composition and method of controlling wireworms in the production conditions of the SEC “Kolkhoz named after V.I. Lenin”, Novokubansky district showed a net income of 2579.16 rubles. per 1 ha and profitability level of 2134%.

Thus, the claimed insecticidal composition and method of controlling pests of crops, including treating the seeds with this composition with the ratio of components specified in option 4 of table 1, allows you to effectively protect the seedlings of plants from damage by wireworms and get an income of 1 ruble of costs in more than 1, 8 times the semaphore standard (table 4).

Based on the foregoing, we can conclude that the claimed group of inventions provides a solution to the problem - to increase the yield of sunflower and expand means of combating soil pests, in particular wireworms, and to achieve this goal - to ensure that the plant more quickly reaches that phase of its development, with where its roots and the root part become "too tough" for wireworms and at the same time use more environmentally safe and cost-effective cocoa for seed treatment tav.
