Description

Zwierzece i roslinne szkodniki zwalcza sie czesto w ten sposób, ze zarazone niemi przedmioty poddaje sie dzialaniu truja¬ cych gazów.Niniejszy wynalazek dotyczy srodka do zwalczania szkodników, dajacego sie latwo i pewnie doprowadzic do zagrozo¬ nych miejsc i umozliwiajacego jego latwa koncentracje w przestrzeni, która ma byc nim wypelniona. Sklada sie on z lotnych trucizn lub ich mieszanin, np. plynny kwas pruski, cyjanowy ester kwasu weglo¬ wego i t. d-, przyczem trucizny sa pochlo¬ niete przez ciala porowate, do.których na¬ lezy tez zaliczac jak najdrobniej rozdzie¬ lone, sproszkowane ciala, Tak w wypadku uzywania mieszaniny drobno rozdzielo¬ nych i porowatych cial z truciznami, jak tez w wypadku mieszaniny porowatych cial z truciznami stalemi o Wysokiem ci¬ snieniu par, powierzchnia znacznie powiek¬ szona powoduje znacznie rychlejsze ulat¬ nianie sie trucizny niz w tym wypadku, gdy sie uzywa niezmieszanych cial gazo¬ wych.Mozna np. nasycic plynnym kwasem pruskim 90^100% CNH ziemie okrzem¬ kowa, diatomit, wegiel absorbcyjny i t. p. materjaly, poczem produkt zamknac w szczelnych naczyniach, np. blaszanych pu¬ szkach i w ten sposób przeniesc na miejsce uzytku. Wystarczy naczynia otworzyc i wy¬ próznic, aby gaz poczal sie wywiazywac* Blaszane puszki moze otworzyc personel zaopatrzony w maski gazowe zapomoca zwyklego otwieraka konserw, poczem pro¬ szkowata zawartosc rozsypuje sie w cienka warstwe. Kwas pruski ulatnia sie wtedy wprzeciagu okolo 10 minut. Pozostala mase absorbcyjna mozna bezpiecznie usunac i e- wentualnie uzyc jej ponownie* Okazalo sie, ze przy uzyciu kwasu pru¬ skiego domieszka cial porowatych, lub cial dzialajacych tak jak porowate, ma te zale¬ te, ze plynny kwas pruski majacy sklonnosc do polimeryzacji stabilizuje sie w wysokim stopniu. Wskutek tego unika sie niebezpie¬ czenstwa wybuchu, który grozi w razie po¬ stepu tego zjawiska.Rozkladu mozna oprócz tego uniknac tez przez dodanie jakiegos stabilizatora np. kwasu siarkowego, szczawiowego i t. p.Ester metylowy kwasu chloro-mrówcza- nego i inne substancje dzialajace na ludzkie blony sluzowe moga byc dodane do tego produktu jako substancje drazniace i o- strzegawcze, aby sygnalizowaly natych¬ miast obecnosc gazów trLjacych i uniemoz¬ liwialy zostawanie w tej atmosferze osób bez masek ochronnych. PLAnimal and plant pests are often combated by subjecting the contaminated objects to poisonous gases. The present invention relates to a pest control agent that can be easily and reliably brought to endangered places and allows its easy concentration in space, which is to be filled with it. It consists of volatile poisons or their mixtures, e.g. liquid prussic acid, cyanic ester of carbonic acid, etc., because the poisons are absorbed by porous bodies, which should also be included as finely divided as possible. solid, powdered bodies, such as when using a mixture of finely divided and porous bodies with poisons, or in the case of a mixture of porous bodies and poisons with steels with a high vapor pressure, a significantly enlarged surface causes the poison to evaporate much more quickly than in this case, when unmixed gaseous bodies are used. For example, one can saturate 90-100% CNH with liquid Prussian acid, diatomaceous earth, diatomite, absorbent carbon and other materials, and then seal the product in tight vessels, e.g. ¬ glasses and thus transfer to the place of use. It is enough to open and empty the vessels for the gas to start discharging. The tin cans can be opened by personnel equipped with gas masks using a simple can opener, and then the powdery contents fall into a thin layer. Prussian acid then evaporates for about 10 minutes. The remaining absorbent mass can be safely removed and possibly reused. * It has been found that when using prussic acid, the admixture of porous bodies, or bodies acting as porous, also has the advantage that liquid prussic acid, which has a tendency to polymerize, stabilizes myself to a high degree. This avoids the risk of an explosion which can occur in the event of an eruption. Decomposition can also be avoided by adding a stabilizer such as sulfuric acid, oxalic acid and tp. Chloroformate methyl ester and other substances acting on human mucous membranes can be added to this product as irritants and warning substances to signal the presence of troublesome gases immediately and to prevent people from remaining in this atmosphere without protective masks.

Claims

Patent claims. 1. A method of using volatile poisons or their mixtures, acting with an increased concentration of gases, for pest control, characterized by the fact that in order to increase the surface of their action, they are mixed with bodies that are either porous or act as a result of their fragmentation. ¬ I just like porous bodies.

2. Pest control agent formulated according to claim 1, characterized by the fact that the liquid prussic acid mixes with porous bodies or acts like a porous body due to the great fragmentation.

3. A pest control agent formulated according to claim 1, 1 and 2, characterized by the fact that irritants and warning substances are added to mixtures of volatile poisons and porous substances, or acting as porous due to the fine grinding.

4. Agent according to claims 1, 2 and 3, characterized by the fact that a stabilizing agent is also added to this mixture. Johannes Lingi er Deputy: M. Kryzan, patent attorney. Printed by L. eogUsfawskiegn, Warsaw. PL
