The pesticide composition

 

The invention relates to the production of pesticides primarily for the protection of plants from harmful insects. The composition comprises chlorophos, surfactant, for example, OP-7, and an organic solvent - dioxane. The composition additionally contains cypermethrin in the following ingredients, by weight. %: chlorophos 10,0-30,0, cypermethrin 0,2-2,0, surfactant, for example, OP-7, 2,0-8,0, dioxane else. This will increase pesticide activity and reduce the cost of the composition. 3 table.

The invention relates to the production of pesticides primarily for the protection of plants from such harmful insects, both harmful bug, grain beetle, grain borer, locust, meadow moth, cabbage butterflies, Codling moth and other insects.

Known pesticide product containing organophosphorus pesticides from list II, which includes seats, dichlorvos, Fenton, diazinon, trichlorfon (chlorophos), marathon, piropos, naredo, chlorpyrifos and fenchlorphos 10 shares each, plus trichlorfon (chlorophos) one share, plus sorbent "2942 S" five parts, plus sorbent "2944 S" five parts, plus xylene 58 shares and plus kerosene 20 shares (the description of the invention to the patent shall godnosti biological mechanism of action on insects and, therefore, the low biological efficiency and increased addiction (resistance) of a living organism to them.

In the same patent 59-8243 described pesticide product containing a PYRETHROID preparations of list I, which includes arisen, arcrole CIS-TRANS, arcrole trance, arcrole CIS-TRANS and arcrole trance and pyrethrin 2.5 the share of each, plus arcrole TRANS 5 shares, plus sorbent "2942 S2" 5 shares, plus sorbent "2944 S" 5 shares, plus xylene at 62.5 share and plus kerosene 20 a share.

The disadvantage of this second known tools is the homogeneity of the biological principle effects on insects and, consequently, insufficient biological efficiency and increased addiction (resistance) of a living organism to them.

These two well-known pesticide funds are used separately from each other.

Known pesticidal agent, comprising the active principle selected from the group metaphos, chlorophos, and an organic solvent, which is dioxane - VAT residue from the distillation dimethyldioxanes production of isoprene, containing, wt.%: Tributylstannyl-1,3,5 - 3,0-4,5 Tertbutanol - 1,0-8,0 Trimethylpentanediol-1,3 - 1,0-9,0 Pernovae alcohols - 6,0-10,0 Pesticide Cove composition can be injected surfactant, for example, OP 7(description of the invention to ed. St. 552941, MCI And 01 N 9/00, 9/36 publication 05.04.77 year).

The disadvantage of this composition is low insecticidal activity in the protection of plants from harmful insects, as well as rapid addiction (resistance) to the insecticide.

The present invention aimed at solving the problem by creating compositions with improved pesticidal activity.

This is achieved by the claimed combination of features.

The invention consists in that the pesticide composition comprising chlorophos, dioxane and surfactant, for example, OP-7, additionally contains cypermethrin, in the following ratio of ingredients, wt.%: Chlorophos - 10,0-30,0
Cypermethrin - 0,2-2,0
Surfactant - 2,0-8,0
Dioxane - Rest
The number of cypermethrin (0.2 to 2.0 wt.%) in the composition of the pesticide composition is optimal.

The introduction of cypermethrin in the amount of less than 0.2 wt.% does not allow to increase the pesticidal activity of the composition.

Introduction cypermethrin more than 2.0 wt.% it is not economically feasible.

As a source of raw material for pesticide compositions were used:
- chlorophos technical;
- dioxane is used in the prototype (ed. St. 552941);
- surfactant OP-7 GOST 8433-81;
- cypermethrin - cyano-3-phenoxybenzyl-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarboxylate - C22H19Cl2NO3.

The invention is illustrated in the examples (table 1).

Pesticide composition was prepared as follows.

The source components are injected into the reactor with a stirrer with transport vacuum created by vacuum pumps. The components are mixed at a temperature of 45-50oAnd atmospheric pressure for 0.5-1 hour.

Ready pesticide composition is removed from the reactor.

The composition of the pesticide compositions are shown in table 1.

The area of application of the pesticide compositions are shown in table 1:
the composition of example 1 - sopockie aqueous solutions for the protection of animals from ticks and fleas;
- the composition according to example 2 - protection of animals from larvae of Hypoderma;
- the composition according to example 3 - pest control against insects in homes and livestock pens;
- the compositions of examples 3-6 - protection of plants from harmful insects in the garden, in the field, the garden, in the country or in the woods.

Before applying finish pesticide tool enter the water when the following before the ku plants in the centers of harmful insects was carried out by ground method using a tractor-mounted sprayers. The area experienced option 10 ha.

The consumption rate of pesticide funds were established as follows:
- crops (against bug - the Sunn pest, cruciferous bugs) - 0.3-0.8 l/ha;
- in the gardens (against Codling moth) - 1,5-3 l/ha;
in forest plantations (against leaf-eating) is 0.5 - 1.2 l/ha

Comparative data supporting pesticide activity of the composition, in comparison with the prototype are shown in table 2.

Comparative data show that, with relatively equal biological efficacy of the treatment significantly reduced the rate of consumption of the proposed composition, which confirms its high pesticidal activity.

In addition, study of the properties of the proposed composition revealed the presence of a synergistic effect of the use of two active ingredients with different mechanism of action on a living organism - chlorophos and cypermethrin.

Biological effectiveness of the pesticide composition when tested in grain against the bug - the Sunn pest in fruit against leafroller, of elm leaf in two and a half times higher than that of a 30% aqueous solution of chlorophos in dioxanone.

When the same biological effectiveness per 1 ha treated pest is of the same result when pest bug of chlorophos in the composition of the pesticide composition according to the invention is spent (in terms of 100%) in 10 times less than pure chlorophos or cypermethrin.

These data confirm the presence of a synergistic effect, resulting from the different mechanism of action on a living organism of the active agent composition.

Thus, the claimed pesticide composition has the following advantages:
- the composition is used in a more convenient form of chlorophos - liquid, quickly soluble;
- increased pesticide activity, because there is a synergistic effect from the use of two active ingredients with different mechanism of action on a living organism;
- largely overcome addiction (resistance) harmful insects to chemicals used, because the composition of ingredients used (chlorophos and cypermethrin), having different nature and mechanism of action on harmful insects;
- the claimed composition cheaper compared to the prototype, because it uses fewer ingredients, the composition having the active principle, wt. %: chlorophos 10,0-30,0, cypermethrin 0,2-2,0, instead 10-86 wt.% on author. St. 552941 on chlorophos and 25 wt. % cypermethrin for commercially available drugs.
