The Fumy pesticide for empty storehouse that the purpose of this invention is to provide a kind of efficient, low toxicity, pollution-free, production safety, the low good disinsection effect of price.
Fumy pesticide for empty storehouse is mixed by chlorophos, triumphant security, oxidant, stabilizing agent and charcoal powder and forms, the percentage by weight of its composition is: chlorophos 18～24, triumphant security 1～1.5 oxidant 20～30, stabilizing agent 4～8 and charcoal powder (or flyash, chimney soot) 40～50. stabilizing agents are sulphur or lead sulfate tribasic or calcium stearate or epoxychloropropane.Oxidant is ammonium nitrate or potassium nitrate or potassium chlorate or ammonium chlorate.Best use prescription is chlorophos 24%, triumphant security 1%, sulphur 4%, ammonium nitrate 24% and potassium chlorate 4% and charcoal powder 43%.
After this Fumy pesticide for empty storehouse ignites and is fuming, contacting of long period can take place with biological target body with the state of long-time Mass in the space in the white cigarette particulate that is produced, its contacting efficiency is much better than inspergation and spray-on process, it is the very hole capital after selling all securities insecticide of wide spectrum of a kind of activity, under general recommended dose, corn weevil, lesser grain borer, red flour beetle, rusty grain beetle, moth class, mite class, square neck cucujid beetle, first-class 30 various pests of tobacco all had extremely strong lethality.Being used for the grain that stores not being had residual contamination behind the hole capital after selling all securities desinsection, is the novel pesticide of a kind of efficient, low toxicity, low-residual.Its production cost is low, and is safe and convenient to use, flameholding, and dosage is few during desinsection, and is economical cheap, is suitable for applying.
The manufacture method of Fumy pesticide for empty storehouse is to pulverize or grind with a stone roller used whole raw materials broken respectively with cracker.Raw material after pulverizing is all sieved by 0.1 mm sieve, and the ratio in aforesaid percentage by weight cooperates then.The raw material that proportions mixed fully to mix thoroughly be the cost fumicants.Notice during manufacturing that raw material must be dry.Pack by the consumption requirement then, but maximum is no more than 1 kilogram.During use, with fumicants on request consumption pack in the paper web or in the plastic sack, and the fuse cord of packing into, light fuse cord, fumicants is lighted the back and is produced a large amount of heat, makes the insecticide oxidation of sneaking in the fumicants and goes out with the smog that forms, the white cigarette particulate that produces can spread for a long time towards periphery, there are the contact of long period, smog can permeate into body of wall, roof and slit, floor in the hole capital after selling all securities with organism, can make the insecticide particulate touch the insect of hiding oneself in hole and slit.
Hole capital after selling all securities insecticide consumption uses the space-time warehouse to want strict sealing with every cubic metre of space medication 2 to 3 gram, light the hole capital after selling all securities insecticide after, the staff withdraws the warehouse immediately, allows this use that the medicine hole capital after selling all securities is airtight to be no less than the dregs of a decoction that the cleaning that opens a position again after 72 hours was fired.Through a large amount of tests, medication 2～3 gram/rice
3The space, airtight 72 hours, the insect lethality rate was 100%.
