RO117828B1 - Biological rodent control composition - Google Patents

Abstract

The invention relates to a biological rodent control composition with biological effect, acting on the basis of diosmosis, dehydration and blocking of the alimentary tube, thereby achieving hemoconcentration with subsequent hypoxia followed by enteric occlusion with toxicoinfection condition, reached by dosing and mixing 39.6% semi-hydrated calcium sulphate, 0.3% Myrtilli folium, 0.1% Digitalis lanatae folium with 30% oat flakes and 30% meat meal up to their homogenization, the percentage being expressed by weight.

Description

RO 117828 B

The invention relates to a bioderatizing composition, used for deratization. Compositions with a raticidal effect are known, containing pseudohydantoinic acid, secondary sodium phosphate and talc, or based on phenylpropargylamine derivatives mixed with a food carrier and a coloring substance (RO 99043, 86734).

Known exterminating compositions contain toxic substances and have the disadvantage of destroying only one individual of the collective (the scout) at a bait with poisonous substances and, due to the installation of pre-death phenomena, to indicate the location of the dangerous product. Due to the pheromones eliminated and scattered by the intoxicated animals, in the detected dangerous areas, the effectiveness of exterminators based on poison or mechanical traps decreases, and it is necessary to wash the traces left by the victims.

The technical problem, which the invention solves, consists in the elimination of these precautions that become unnecessary in the case of using the new bioderatizing composition, because it acts on the basis of osmosis, dehydration and blockage of the digestive tube, the impossibility of these mammals being known to correlate the causes with the effects , in the time since the death.

The bioderatizing composition, according to the invention, based on active substances, a food support and an attractive component, consists of 39.6% semihydrated calcium sulfate, 0.3% Myrtilli folium and 0.1% Digitalis lanatae folium, 30% flakes of oats and 30% meat meal, the percentages being expressed by weight.

The bioderatizing composition is presented in the form of a homogeneous white-grey powder with a specific smell of meat meal.

Semihydrated calcium sulfate is the gypsum and represents, along with Myrtilli folium and Digitalis lanatae folium, the active substances of the composition. The food support consists of oat flakes, and the attractive component is meat meal.

The advantages of the bioderatizing composition are:

- the physiopathological mechanisms triggered after the ingestion of the product cause the death of rodents (mice and rats) within 5 ... 6 days, as they are already in the galleries and nests of the community; under these conditions, rodent corpses do not remain on the soil surface, excluding the danger of epidemics or epizootics.

- due to the long time interval, until death, compared to the action time of exterminators whose active substance is a toxic substance, the product does not create panic in the rodent community, nor does it cause marking with pheromones of the area where the bio-eraticide substance was consumed ;

- under the conditions of using meat meal as an attractant, the specific smell of spoiled meat does not attract domestic animals, and when they try to eat it, they will give up due to the taste and the drying effect produced on the tongue mucosa, given by the semi-hydrated calcium sulfate;

- the product is biodegradable through hydrolysis and oxidation; after about 7 days, the product left unconsumed, at the application site, is a hydrated calcium sulfate, similar to sulfates in the soil;

- the product does not affect the ground water, if, accidentally, the rainwater carries the product into the soil, unlike rodent control products, based on toxic chemical substances;

- in the case of the new product, the phenomenon of contamination of personnel engaged in its production, handling and use does not occur;

- the conditions imposed by labor protection are much less severe in the case of the new biodeteratist product, due to the fact that the ingredients from which it is obtained are not toxic, irritating or allergenic.

The bioderatizing composition, according to the invention, acts through a biological effect, the mechanism of death being the following:

- calcium sulfate, having reached the digestive tube, removes water from the blood serum, based on the principle of osmosis, achieving hemoconcentration with subsequent hypoxia and, later, intestinal occlusion with a toxic state.

Claims (1)

RO 117828 Β - alkaloids from the plants in the composition, in a therapeutic and non-toxic concentration, cause an increase in diuresis (thus accentuating dehydration) and reduce the heartbeat (negative dromotropic effect), accentuating tissue hypoxia, hastening and establishing the death of rodents. Next, a concrete example of the invention is given. To obtain 100 kg of bioderatizing product, weigh 39.6 kg of calcium sulfate, 0.3 kg of Myrtilly folium, 0.1 kg of Digitalis lanatae folium, 30 kg of oat flakes and 30 kg of meat meal, grind and mix, until homogeneous, at a temperature of 20 ... 25°C, 60 in a closed space and in a dry environment. After obtaining, the product is packed in double polyethylene bags, heat-sealed, of 0.8 kg, which are then inserted into inscribed cardboard boxes, sealed at both ends. The iTiai product can be packed in double polyethylene bags of 5 kg, then inserted into labeled paper bags. in this way, product security and ease of handling, transport and storage are ensured. 65 The bioderatizing product absorbs water very easily, inactivating itself, therefore it will be protected from moisture during transport, storage and use. Transport or storage will be done in clean conditions, avoiding contact with petroleum substances or substances with a repulsive smell, because rodents will avoid consuming them. The product will not be placed directly with the hand, in order not to take the smell of the person doing the extermination, it being known that, in this case, mice and rats avoid consumption. The placement of the product is done near the rodent galleries in homes, warehouses, as well as outside, if necessary. The product (300 ... 400 g) is placed on an impermeable layer (polyethylene film, tin, glass, etc.) and protected from the weather or other sources of moisture. As the product is consumed by the rodents, the initial amount is replenished, repeatedly, until 75% remains untouched. Deratization occurs after 2 ... 3 weeks, depending on the infestation. Test to assess the effectiveness of the bioderatizing composition. A batch of five male and five female white rats is used. in 80 individual jars, which feed on the bioderatizing composition. in the amount of 50 g for an individual. The animals treated in this way are monitored and observations are made which are recorded daily in a register. It is being followed. especially, the appetite, the consumption of bioderaticide, the specific symptoms, the date of death and the anatomo-pathological changes, at the necropsy. After ingesting the bioderatizing composition, approximately 40 ... 45 h, the appetite disappears and drowsiness and 85 haripilation set in. Later, clinical phenomena specific to intestinal occlusion appear, and after 130 h, hypovolemic shock sets in. Death occurs approximately 135 h after ingestion in all rats subjected to the experiment. Claim Bioderatizing composition, based on active substances, a food support and an attractive component, characterized by the fact that it consists of 39.6% semihydrated calcium sulfate, 0.3% Myrtilli folium and 0.1% Digitalis lanatae folium, 30% oatmeal and 30% 95 meat meal, the percentages being expressed by weight.
