Definitions

• the subject of the current invention is a carrier material for mosquito larvae killing pesticides, and mosquito-larvae killing products and procedure of their manufacture, and mosquito larva extermination method with spreading them from air- or water-craft.
• Suitable pesticide product floats on the water surface, environment friendly, sufficiently strong for spreading, from air- or water- crafts, provides maximum scope of spreading and a granulate form for ensuring long spreading distance together with homogeneous distribution of spreaded particles, and finally disappears from the water surface (by sinking or dissolving) after spreading and killing the mosquito-larvaes.
• a new carrier material for mosquito larvae killing pesticides new mosquito-larvae killing products containing this carrier material; the procedure for manufacture of the carrier and the mosquito- killing products; the way of their spreading; and the method of mosquito larva extermination with spreading from the air- or water-crafts are described.
• the basis of this current invention is the creation of an advantageous geometrical - preferably a ball-shaped - form of granules, by the granulation of silicate rocks and well-shapable clay.
• pores are created in a known way.
• the density of the granules less than the density of water due to the presence of the pores. This way the material can float on the water surface meanwhile its pores are very slowly filled with water.
• the density of the granules increases. When its density becomes higher than that of the water, the granulates start to sink.
• the subject of this current invention is a clay composition that is burnt and strength from a mechanical point of view and contains pores.
• This clay composition has a homogeneous distribution of the granulate sizes and has an advantageous, preferably a ball-shaped geometrical form. It is capable of floating on the water surface for a certain period of time for some minutes or days until its pores are filled with water and, due to the increased density it sinks under the water surface.
• This product can advantageously be used as a supporting material for chemical and biological mosquito-larvae killing pesticides.
• This present invention refers to those mosquito-larvae killing compositions containing chemical or a biological pesticides that is known by itself and which also contain these two pesticides that are found in the granules of the carrier material or they are stuck to the surface of it.
• the manufacture of the mosquito-larvae killing material granules also belongs to the current invention by using a procedure to fix the chemical or the biological pesticides into the pores of the porous support material or onto its surface.
• the mosquito- larvae killing pesticide when mixed in a water-soluble glue material or in the composition of stick can be based on carboxymethyl cellulose, starch or their mixtures, the surface of the support material is covered by these mixtures which are then washed off by the water during use in a natural environment.
• the surface containing the glue material is covered by an inert dust material, for example, by starch or mineral substances such as limestone or the dust of dolomite. This way sticking can be avoided.
• a preferred embodiment is when the support surface coated with the glue material is also covered by the dust of the mosquito-larvae killing material powder.
• This invention also includes the spreading of the mosquito-larvae killing material products fixed on the support material mentioned above by the application of centrifugal plate on water or air crafts.
• the particles of the precursor material before burning the clay to develop the pores of the mosquito-larvae killing material carrier material, the particles of the precursor material is formed into a ball-form which form is the most advantageous regarding air resistance and homogenity of the picture of spreading.
• the aim of the present invention is that the mosquito-larvae killing material products should cover the water surface as much as possible and ensure a large scope of spreading.
• the favorable ball diameter is 0.5-10 mm and the most favorable size is 2-6 mm. In the case of the 3 and 5 mm granulate in a ball diameter the relationship between the coverage and the scope of spreading is shown in the Table 1.
• the mosquito-larvae killing material product contains carrier material having a certain pore size (developed by our method), thus ensuring that the mosquito-larvae killing material product remains on the water surface for a time interval of 0.01-12 hours, then it sinks within 0.01-24 hours.
• the present invention indicates that the support material and the mosquito-larvae killing material product covering the > support material is transportable and storable due to its physio-chemical and biological stability and its mechanical strentgh.
• the mosquito-larvae killing material composition floats on the water surface until it has its effect, so the mosquito larvas are effectively destroyed by the spreaded products appearing at the habitat of the larvas. Having been developed its effect, the composition sinks within a few hours due to the increased density caused by the amount of water filling the pores. This way the accumulation of the carrier material on the shores and at the foot of the reeds, as well as the environmental and economic damage are avoidable.
• the support material is made up of silicate rocks, which does not cause any environmental damage neither in waters nor in their surroundings.
• a given composition about mosquito larva extermination is introduced without restricting the claim of the patent.
• Carrier material montmorillonit found in nature and shaped into balls of 3-6 mm in diameter size, and bentonite clay mineral (containing 6% organic matter) are heated at 200-400 C° to burn the organic matter and to get the pore system, then they are further heated at 800-1200 C° until reaches of strength an earthenware. After the granulates cool down they are classified according to their size, then are soaked in the water suspension containing 1 % aq. carboxymethyl-cellulose and the biological mosquito-larvae killing material product containing Bacillus Thtirengiensis as an pesticide. This way composition of 4 % pesticide is created.
• the maximum scope of spreading and the average coverage per square meter is 5 and 10 kgs/hectare in the case of the spreaded material
