Description

A kind of contact-to-kill type asepsis quick-acting pesticide

Affiliated technical field

The present invention relates to the used insecticide of a kind of farming, woods, animal husbandry or daily life, particularly a kind of contact-to-kill type asepsis quick-acting pesticide that contains alkyl benzene sulphonate or alkyl hydrochlorate.

Background technology

At present, the kind of agricultural chemicals or insecticide is a lot of on the market, and chemosynthesis is arranged, and has biology to make or the like.Wherein chemical pesticide or insecticide mostly have higher toxicity, use some agricultural chemicals of back or insecticide also to reside in grain for a long time, among the crops such as vegetables, also residue in the soil, even in meat, fowl, egg milk, fish and drinking water, can both find the trace of agricultural chemicals or insecticide sometimes, not only the healthy of people there is infringement, and contaminated environment, the ecological balance destroyed.Chinese patent notification number: CN1111004C, the day for announcing: on June 11st, 2003, denomination of invention: " fruit-vegetable pesticide and production method thereof ", proposed by neopelex, formulated insecticides such as phosphoric acid, phenol, boric acid and ethanol, to the moccasin skin insect on fruit tree, vegetables, the flowers and other crops, moth etc. have significant killing effect, have little poison, efficient, cheap non-harmful characteristics.But it is complicated that this insecticidal formulation still shows, and wherein relates to severe toxicity and poisonous composition, and its residue is difficult to degraded, and environment is had pollution, and production cost is relatively still higher.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, nontoxic, a kind of contact-to-kill type asepsis quick-acting pesticide efficiently is provided, it is easy to make, and is with low cost, good disinsection effect.

Technical solution of the present invention is: a kind of contact-to-kill type asepsis quick-acting pesticide, form by the raw material of following weight component: eight-eicosyl benzene sulfonic acid or sodium palmitate or sodium stearate or Nonsoul PK 1 or potassium octadecanate 1-4 part, 100 parts in water.

The present invention can also its composition by weight be: 3 parts of DBSA, 100 parts in water.

The present invention can also add potash or potassium hydroxide or ammoniacal liquor and regulate insecticide pH value=6-8.

The present invention can also its composition by weight be: 1.5 parts of sodium palmitate or sodium stearates, 100 parts in water.

Eight-eicosyl benzene sulfonic acid such as DBSA (R.C ₆H ₄, SO ₃H) external appearance characteristic is brown oily liquids, and slight sulfuric acid smell is arranged, and is soluble in water.Be used to produce synthetic detergent mainly as surfactant at present, also have as the emulsifier of agricultural chemicals or insecticide or the auxiliary agent in oil field and use.Its no residual hazard, easily degraded does not have the poisoning effect to domestic livestock and poultry and wildlife, and human body is also had no side effect.

Palmate or octadecanoate mainly are sodium palmitate (C ₁₅H ₃₁COONa) or potassium (C ₁₅H ₃₁COOK) and sodium stearate (C ₁₇H ₃₅OONa) or potassium (C ₁₇H ₃₅COOK), i.e. SOFT SOAP or hard soap, on external appearance characteristic, sodium palmitate is a faint yellow solid, sodium stearate is an Off-white solid; Nonsoul PK 1 is a honey shape liquid, and potassium octadecanate is a lard shape liquid, all is alkalescent.Above alkyl benzene sulphonate, alkylbenzenesulfonate and palmate, octadecanoate all have the carbon atom more than 8, and have stronger polarity, will by the spray solution of 8 alkyl benzene sulphonates of forming to 20 carbon atoms or benzene sulfonate or palmate or octadecanoate and water modulation in insect on one's body after, sensitivity response appears in its insect immediately, and it is dead just to struggle in very short time.And benzene sulfonamide acids solution that carbochain is long more or alkyl acid salting liquid insecticidal effect are good more.The insecticidal mechanism of alkyl benzene sulphonate or alkylbenzenesulfonate or alkyl hydrochlorate is not thoroughly understood fully as yet, analyzing its explanation through Primary Study is: alkyl benzene sulphonate or alkylbenzenesulfonate or alkyl hydrochlorate are the stronger active anions of a kind of adhesive force, and insect mainly relies on skin to breathe, when the insect body surface is stained with alkyl benzene sulphonate or alkylbenzenesulfonate or alkyl acid salting liquid, these anion can creep into the dermal respiration road that firmly blocks insect in the spiracles numerous and tiny on the insect skin surface from the aqueous solution, cause the insect acute anoxia to be choked to death and die.The invention has the beneficial effects as follows: compare with biopesticide with other chemical pesticides and have that desinsection speed is fast, insecticide efficiency is high, no residual hazard, do not produce chemical sproof characteristics.After as long as insect has contacted alkyl benzene sulphonate or alkyl benzene sulphonate salting liquid or alkyl hydrochlorate on one's body, just very fast death, general about 3-5 of desinsection time minute; Insect corpse residual hazard after the death is very little, and all no abnormal reaction after bird is edible is pollution-free substantially to environment; By the contact desinsection, its insect can not produce drug resistance; The desinsection kind is wider, for harmful insects such as locust, pine caterpillars, fall webworm, fly, mosquito, cockroach, ant, termite, spider, longicorns tangible killing effect is arranged all, domestic animal and family domesticated animal parasite are on one's body also had insecticidal effect well; And insecticide wide material sources of the present invention, production cost are low, easy to use, and locust or kill the occasion of deinsectizations on a large scale such as pine caterpillars is specially adapted to go out.

Embodiment

The present invention is described in further detail below in conjunction with embodiment:

The component of insecticide of the present invention and prepare fairly simplely, its component (weight portion) is as follows: eight-eicosyl benzene sulfonic acid or eight-eicosyl benzene sulfonate or palmate or octadecanoate are 1-4, water is 100.Have 8 carbon atoms above alkyls benzene sulfonic acid or alkyl hydrochlorate insecticidal effect is preferably all arranged, if the more effect of amount of carbon atom can be better, the cost of its product also can be higher.Eight-eicosyl benzene sulfonic acid or eight-eicosyl benzene sulfonate or the mixed proportion of 16-octadecyl hydrochlorate in water are too low, insecticidal effect can descend, the good more but cost of the high more insecticidal effect of its concentration rises relatively, and alkyl benzene sulphonate or alkyl benzene sulphonate salt pair leaves of plants, bud have certain infringement, make its slight yellowing.At present, the chemical products of alkyls benzene sulfonic acid mainly have only DBSA and dodecyl benzene sulfonate, wherein dodecyl benzene sulfonate comprises neopelex or products such as potassium or calcium or ammonium, consider from helping crops or plant growing, adopt DBSA ammonium or potassium relatively good.Certainly also can produce alkyls benzene sulfonic acid or the alkyls benzene sulfonate product that is specifically designed to desinsection if necessary.For palmate and octadecanoate, include only sodium palmitate, Nonsoul PK 1, sodium stearate, four kinds of products of potassium octadecanate usually.And sodium palmitate and sodium stearate are that the hard soap application is extensive especially, and production cost is lower.

When adopting DBSA or benzene sulfonate preparation insecticide, its component (weight portion) is: DBSA or Potassium dodecylbenzenesulfonate are 1-4, and water is 100.Wherein preferred component (weight portion) is: DBSA or Potassium dodecylbenzenesulfonate are 3, and water is 100.The compound method of insecticide is: two kinds of raw materials are directly blent to stir in proportion get final product.Preparation back insecticide generally is acid, at this moment can add the pH value that potash or potassium hydroxide or ammoniacal liquor are regulated insecticide, to reduce the infringement to leaves of plants, bud.The scope that the pH value of insecticide is controlled at PH=6-8 is better.Above conditioning agent contains compositions such as the useful potassium of crops, nitrogen, can help the growth of crops after using as agricultural insecticide.If can also in insecticide, add flavouring agent, preservative etc. routinely during the insecticide that preparation family uses.

The method of employing palmate or octadecanoate preparation insecticide and the mode of abovementioned alkyl benzene sulfonic acid are basic identical, and the ratio of its preparation (weight portion) is that palmate or octadecanoate are 1-4, and water is 100.Can adopt sodium palmitate or sodium stearate is 1-4, and water is 100; Also can adopt Nonsoul PK 1 or potassium octadecanate is 1-4, and water is 100.The component (weight portion) of preferred employing sodium palmitate or sodium stearate is 1.5, and water is 100.The palmate or the octadecanoate aqueous solution of preparation are alkalescent, and is more approaching with the pH value of leaves of plants, stem, so generally do not need to add the pH value conditioning agent again.The palmate or the octadecanoate aqueous solution are less to the infringement of plant, crops, do not have toxicity, and insecticide cleans convenient, and insecticidal effect is also more satisfactory, are more suitable for as nuisanceless and pollution-free food such as vegetables, and the insecticide of economic crops such as melon and fruit uses.

Above-mentioned insecticide is a kind of action time of short direct contact killing type chemical insecticide, and only the contact insect can desinsection under liquid condition for it, if liquid has been done later contact insect or eat for insect and all not have insecticidal effect.Therefore, when using, the fluid insecticidal for preparing can be packed into manual sprayer or power driven sprayer, fluid insecticidal is sprayed directly on the harmful insect health with the droplet state by the nozzle on the sprayer, just can kill harmful insect immediately.Directly the insecticidal effect of spray pattern is better, and its killing rate is about 95%, and the mean time to death of spraying contact back harmful insect is 2-5 minute.For being difficult for found harmful insect, the mode that can take carpet type to spray as long as hung up the globule on the plant leaf that guarantees to be sprayed, also can reach satisfied insecticidal effect, and average killing rate can reach more than 80%.For locust or pine caterpillars disaster, adopt insecticide of the present invention directly to spray desinsection, its insecticidal effect and economic benefit are more obvious.And extremely locust does not have residual hazard substantially, and from the safe and sanitary angle, dead locust can be used as high protein feed and eats for poultry and livestock after process washing, drying, pulverizing.For harmful insect on one's body the domestic animal such as flea etc., can with this insecticide spraying on the fur of animal, can spray some more, squirt thoroughly, get final product with its fur of body cleaning of flushing with clean water animal after waiting a few minutes.
