The compounds of formula 1 have a broad biocidal effect and can be used to combat various kinds of plant or animal pests, a firer, as acaricides, insecticides, ectoparasiticides, as well as plant growth regulators or herbicides.

They are suitable in particular for tick control, for example, of the families: Ixodidae, Argasidae Tetranychidae and Dermanyssidae, but we need to make sure that compounds of formula I, where RI is o-methyl, R2 is p-chloro and Kz are hydrogen, have a prolonged effect against larvae and adults, while the compounds in which RI-o-methyl, R2 is l-methyl and R3 are hydrogen, have a high toxic effect primarily as ovicides.

The compounds of formula 1 also have a favorable effect on harmful insects for plants and animals} and can be used to control insect families: Acrididae, Blattidae, Gryllidae, GryHotalpidac. Tethyerea Noctuidae, Lymantriidac, Pyralidae, Galieridae, Culicidae, TipuHdae, and also most often for the control of aphids (for example, Myzis pcrsiсae). Thus, cr) unification of the form. Ch 1 is particularly suitable for combating harm; c 1 M plants are insects in fruit, vegetable and ornamental plants.

Acaricidia or I1; se; ctiyidnos dyestliHe can be extended by adding other instegnides and / or acaricides.

Suitable additives are, for example, organic phosphate phosphides; nitrophenols and their products; formamipipa; urea; pyrethrin-like compounds; vap6aMaTbi and chlorinated hydrocarbons.

The compounds of formula 1 may be used alone or in conjunction with iridescent and / or excipients. Suitable carriers and excipients may be solid or liquid and correspond to substances customary in the art of preparing compositions, such as natural or regenerated substances, solvents, disnergators, wetting agents, adhesives, compactors, binders and / or fertilizers.

For application, the compounds of formula 1 can be processed into pulverized preparations, emulsion concentrates, granules, dispersions, sprayed compositions, solutions or suspensions in conventional devices.

The preparation of the proposed agents is carried out by carefully moving and / or grinding the active substances of the formula 1 with suitable inert carriers, dispersants or solvents. Active agents} substances can be used in the following forms.

Example 1. Powdered drug.

The following substances are used for the preparation of the pulverulent preparation:

The resulting solution is sprayed with HHe: vi and kaolin and then the acetone is evaporated in vacuo.

PRI: measure 3. Wetting scapula. The following substances are used for the preparation of the wettable pHOHIKA, wt. including:

A) 40 active substances, 5 ligensulfonic acid, 5 porous salts, 1 dibutylnaphthalenesulfonic acid sodium salt, 54 silicic acids.

B) 25 active substances, 4.5 lignesulfonate calcium, 1.9 blends of Chamnan chalk (hydroxyethyl cellulose 1: 1), 4.5 dibutlphenaphthalene sulfonate sodium, 19.5 silicic acid, 19.5 chalk Shampap, 28.1 kaolium.

B) 25 active ingredients: o ;; co-efficiently 2.5 isooctyl phenoxyethylene ethylene ethanol, 1.7 mixtures of Chamiai chalk, 8.3 sodium alumosilicate, 16.5 kieselg, ra, 46 kaolpna.

D) 10 active substances, 3 mixtures of sodium salts of saturated sulphates of fatty leach, 5 naphthalene sulfonic acid / formaldehyde condensate, 82 kaols.

The active substances are carefully biased with additives and ground. Wetting powders are obtained which are diluted with water to suspend any desired concentration.

Example 4. Emulsifiable concentrates.

To prepare an emulsifiable concentrate, the following substances are used, wt. including:

A) 10 active substances, 3,4 epoxy vegetable oil,

3.4 a combined emulsifier consisting of a polyglycol ether of fatty alcohol and an alkyl aryl sulfo calcium salt of calcium, 40 dimethylformamide and 43.2 xylene;

B) 25 active substances,
