The subject of the invention is a herbicide, the active ingredient of which comprises a compound of general formula I, in which R and R1 are the same or different and represent a methyl radical or ethyl, where R may be in the cis or trans position, n is an integer 0 or 1, and R2 is a hydrogen atom, a lower alkyl, alkenyl or alkoxy radical, a halogen atom, a nitro group, a lower group an alkylthio or a heterocyclic radical, the active ingredient mixed with the stabilizer. The compounds of formula I act on insects in a different way than other insecticides, namely they interfere with the normal process of insect development, inhibit the initiation process and cause the formation of individuals unable to life or reproduction which contributes, at least indirectly, to the destruction of insects. The compounds of formula I are discussed in the application of the United States of America No. 856,140 of September 8, 1969. These pigs are used in the form of dusts or emulsions and other agents sprayed into the environment of insects, they are also issued on the action of heat and ultraviolet rays from sunlight, which causes their decomposition after some time. It has been found that the durability of these insecticides can be significantly increased if a compound of general formula 2 is used as an additive, where R8, R4 are the same or different and represent a hydrogen atom, a lower alkyl, alkoxy or carboalkoxy radical, a cyclohexyl or phenyl radical, or a halogen atom. These compounds are known from US Patents No. 3,004,896 and No. 3,189,615 as UV resistant substances for plastics such as polypropylene, polyesters, polyvinyl chloride, polyethylene, acrylic resins, ¬ polyurethanes, polyacetals, polycarbonates and polyamides. Some of the compounds of formula II are included in the formulation known as Tinuvia (Geigy Chemical Corporation). Examples of such compounds are: 2- (2'-hydroxy-5'-methylphenyl) -benzontriazole, 2- (3'-III-tert-butyl-2'-hydroxy-5'-methylphenyl) -5-chlorobenzotriazole and 2 - (3 ', 5'-two-tertiarybutyl--2'-hydroxyphenyl) -5-chlorobenzotriazole. The stabilizer of the formula II is generally added in an amount of about 0.1-10% by weight of the active compound of the formula 1. The mixing may take place in any manner known in the art for the preparation of insecticides. Examples. Many tests have been carried out to determine the stability of the herbicidal compound of formula III mixed with various stabilizers of formula 2. A given amount of the herbicide is spread over a thin layer over the top of the clean glass plates and exposed to sunlight. a period of 8 hours on 3 consecutive days, i.e. a total of 24 hours. The samples are then rinsed with acetone, diluted in the appropriate ratio and the resulting 81,788, 81788 4 solution is treated topically with Tenebrio pupae. The ability of the test compound to inhibit or interfere with the process of insect conversion is measured by treating the penultimate larvae of insects and then examining the characteristics of the mature specimen. The larvae of the yellow mealworm of Tenebrio molitor L. are tested. These larvae are cultivated at 28 ° C and in an atmosphere with a relative humidity of 40% on bran. Prepupae are harvested from the culture and kept in separate containers. The larvae are collected once a day and are 1–25 hours long during the test. The larvae of Tenebrio molitor L are administered to the abdomen with a syringe in 0.5 or 1.0 microliters of acetone, and then the larvae are kept at a temperature of 28 ° C in an atmosphere with a relative humidity of 40% until the individual hatch. mature, which lasts 6-8 days. These individuals are divided into positive, negative and dead individuals. The positive group includes those with the typical pupal epithelium, urogenital organ, mesh, abnormal wings, etc. For each test, 2 groups of 20 pupae are used and the mean results are determined. The dose of the compound necessary to kill the chrysalis or to cause the positive reaction described above in 10 cases out of 20 is determined. These doses of the DM are given in the table in 2 headings, namely for the medium subjected to irradiation and not subjected to sunlight. The stabilizer used in sample 3 is known as Irgonox 1010, and the compound used in trial 4 as Irgonox 1076, manufactured by Geigy Chemical Corporation, Ardsley, USA. The agents of the invention may be applied directly to foodstuffs, seeds and other materials endangered by insects. For such direct use it is preferable to use a formulation which is not volatile. It should be emphasized that the agents according to the invention may not be active by themselves, but become active under the influence of external factors such as light rays, or under the influence of a physiological action which occurs when the active substance of the agent according to the invention is absorbed in the pest. The compositions according to the invention are preferably used in the form of a liquid, for example an emulsion, suspension or aerosol. The concentration of the active ingredient in the agent varies fairly broadly, but is usually not more than 50% by weight. 15 20 25 30 PL PL
