The conditions for obtaining their constants for the compounds obtained are given in tab;
The compounds of the above formulas can be used to prepare pesticidal formulations intended to combat plant parasites, indoor parasites, and parasites of warm-blooded animals and containing these compounds as an active principle.
In formulations intended for agricultural use and indoor use, one or more other pesticides can be added to the active principle or the active principles. These formulations can be in the form of powders, granules, suspensions, em, lsii, solutions, solutions for aerosol gels, combustible tapes, baits or other preparations that are classically used for the name of this type of compound.
I
In addition to the current beginning, (usually
These formulations contain a carrier and / or surfactant, non-ionogenic, which provides a uniform dispersion of the composition of the mixtures of substances. The carrier used may be a liquid, such as water, alcohol, hydrocarbons or other organic solvents, mineral, animal or vegetable oil, powder, such as tapes, clays, silicates, kieselgur sp1 solid fuel.
Products of this formula can also be used to fight against those of us in particular to, in particular, against flies, mosquitoes and cockroaches.
515
The compounds obtained by this method can also be used in the fight against ticks and nematodes that are parasites of plants, i.e. The compounds may also be used to prepare acariid compositions, as well as nematicidal compositions containing these compounds as an active principle.
Insecticidal compositions preferably contain 0.005-10% by weight of the active substance. For indoor use, insecticidal formulations are used in the form of smoke-forming compounds. In this case, insecticidal formulations for the inactive portion may consist of combustible serpentine or a fibrous non-combustible substrate. In this case, the resulting fumigant, after administration of the active substance, is placed on a heating apparatus, such as an electric radiator.
When insecticidal serpentine is used, the inert carrier may be the zhigunts bagasse compound, Tabu powder, the zhigunts stem powder, cedar leaf powder, wood powder (pine sawdust), starch, and coconut shell powder.
Then, the dose of the active substance may be, for example, 0.03-1 wt.%.
In the case when irero-friable, fibrous substrate is used, then the dose may be, for example, 0.03- 95% by weight.
The compositions according to the invention for use in rooms can also be obtained by preparing a sprayable liquid oil on the basis of the active principle, and this oil impregnates the wick of the lamp and is thus subject to combustion. The concentration of active principle introduced into the oil is preferably between 0.03 and 95 May.
Acaricidal and nematicidal compositions can be in the form of powders, granules, suspensions, emulsions, solutions.
For acaricidal use, wettable powders are preferably used for spraying on leaves which contain 1-80%, or spraying liquids on leaves containing 1-500 g / l of active principle. You can also use powder
06
Leaves powder containing 0.05-3% active ingredient.
For nematologic application, it is preferable to use soil treatment fluids containing 300-500 g / l of active ingredient.
The licaricidal and nematicidal compositions of the invention are preferably consumed in doses of 1-100 g of active substance per hectare.
Compounds of this formula can also be used to control ticks that are parasites of animals, in particular against ticks of the genus Beophilus, Hyalonnia, Amblyomnia and Rhipicephalus, or to fight against any kind of scabies, in particular tick scabies, chorioptic scabies and psoroptic scabies.
I
The compounds of the formula may thus be employed. for the preparation of compositions used in the fight against ticks, which are parasites of warm-blooded animals, and which contain these compounds as an active principle. The formulations may be administered externally by spraying, shampooing, bathing or smearing. They can also be introduced by spinal lubrication according to the method of Pur he, as well as the digestive tract.
When dealing with the control of ticks that are animal parasites, the products of the invention are often introduced into food formulations in aid of a nutritional mixture adapted to animal feed. The nutritional formula may vary depending on the animal breed and may contain cereals, sugars and grains, soybean meal, peanut and sunflower, animal flour, such as fish meal, synthetic amino acids, mineral salts, vitamins and antioxidants,
The compounds of the above formulas can thus be used to prepare formulations intended for animal feed and containing these compounds as an active principle.
In order to excite the biological activity of the products obtained according to the method of the invention, it is possible to add to them the classical substances of synergism used in this case, namely 1- / 2,5,8-trioxadodecyl /
