Description

*** - «\ Mtm \ | Int. Cl *. A01N 9/02 Creators of the invention: Jan Swiech, Stanislaw Lakota, Bohdan Sledzdnski, Janusz Swietoslawska, Stanislaw Byrdy, Zdzislaw Górecki, Jerzy Peczak, Jerzy Banas Authorized by the patent: Institute of Organic Industry, Warsaw (Poland) Pesticide, especially for pest control beet The subject of the invention is a pest killer, especially for pest control of crops beetroot containing, as a biological factor, ak¬ active mixture of known insecticides or CH.

Among the many substances with a pest used for the protection of beet crops one of the most effective is 0,0-dimethyl-0-1-methyl-2- / N-methylcar- phosphate bamoyl / vinyl with the common name monocro tofos. This substance is used in the form of six the rule of preparations used to control the number of pests, especially for control purposes cream and aphids found in the crops of bura¬ cows.

An unfavorable feature of the most powerful sub pesticides, including mono- Krotofos, used to protect the crops of bura Toxicity is relatively high compounds for steel-blooded organisms.

Steel is much less toxic to organisms heat is a known compound with a chemical name l-hydroxy-2,2,2-trichlorethyl-0,0-di- phosphonate methyl and the common name of titichlorfon. Related it is used in the form of numerous formulations for the control of various pests insect and in beet crops to combat litter and soil pests. Unfavorable a feature of trichlorfon is its low operating efficiency pouring on beet crops pests. 125 Surprisingly, it was found that higher efficiency was achieved to carry a pesticide from the effectiveness of monocot the phosphorus and triohlorophon distinguished measure according to of the invention containing as an active ingredient a mixture of the insecticides mentioned above in the proportion of 10 parts by weight of monocrotophos to 1 up to 100 parts by weight of Itrichlorphone.

The remedy according to the invention can find a lot widely used in the protection of plants for decay hunting various species of harmful insects, especially aphids, litter and soil pests, especially in beet crops.

An advantageous feature of the measure according to the invention is less toxic to heat-heat organisms compared to the toxicity of monocrotopho- su.

It is possible to use smaller doses of the agent according to the invention from effective doses of toclilor- phoneme and monocrotophos is also important advantageous from an environmental point of view na¬ natural and economical use.

The pesticide of the agent according to the invention The risk is a mixture of monocrotophos and tri chlorphone can be used in its pure form, but it is more preferable to use it in typical formulations, for chemical killers and utility forms. The composition of the agent outside the pesticidal agent may be a general unknown auxiliary additives such as solvents, carriers, emulsifiers, dispersing agents, wetting agents 104 1203 104 120 4 jace, improving adhesion, stabilizing, color fluff and fragrance. It is possible to apply The agent according to the invention in the form of such symbols Usable forms such as emulsifying solution and for diluting powders, dusts and micro granules for dusting, granules for spreading solutions, pastes and powders for suspensions in liquids, dilution pressurized liquids, concentrates to kifea ^ fine spray and others.

Furthermore, an agent according to the invention may be present estimate with known predicoricides, fungicides, plant growth regulators, sy- nergetics and attractants, therefore there are Ability to limit the number of application procedures Ifti protected plant crops.

The measure according to the invention is generally prepared by the known methods of surrender the ingredients of the agent are properly mixed, dilution dropping, saturation, concentration and other typical technological operations.

High pest homicide the debt of the invention and the method of preparing one of typical utility forms illustrate, respectively, without limiting the scope of the invention, the following examples.

Example II. Insecticidal activity. The property Insecticidal properties have been defined as home mousse (Musca itemestica) drop method! (topdcal ap- plication) by applying drops of acetone solution standard substances and the agent according to the invention on the body of a fly. Average dose developing the mortality rate of 50 * / of the fly population was calculated using the will give logarithmic probiotic the expected (LDM theoretical) was calculated for the agent in the debt of the invention as set out in example I.
