Abstract
The invention discloses a biological pesticide capable of killing ova and a preparation method and application thereof. The biological pesticide contains emamectin benzoate, escin and griffonia seed oil. The biological pesticide capable of killing the ova is prepared by mixing emamectin benzoate, escin, griffonia seed oil, a polyalcohol nonionic surfactant and carboxymethylcellulose, and adding water during stirring to form homogeneous and slight turbid emulsion. The biological pesticide has the effect of expelling mosquitoes and obvious effects of killing pests in the living environment of people, such as cockroaches, termites and ants, wherein the killing rate is over 95 percent; besides adult pests, the biological pesticide can also kill the ova to prevent the reproduction of the pests so as to greatly improve the pest killing effect, and overcomes the limitation that the main active ingredient in the formula, namely emamectin benzoate cannot kill the ova; and simultaneously, the biological pesticide can spread toxin to pest populations because of mutual lick habits of the ants and cockroaches.
Description
Technical field
The present invention relates to a kind of biopesticide, biopesticide of particularly a kind of energy killing ova and its production and application.
Background technology
In the last few years, harmful effects such as the environmental destruction that a large amount of use of chemical pesticide caused, murder by poisoning people and animals, target organisms pesticide resistance were more and more worried by people.A kind of new and effective agricultural chemicals to environment and people " close friend " is expected by people always.Biopesticide has people, animal and eco-environmental impact little just, and is pollution-free to agricultural product, with strong points to target pest, helps protecting pest natural enemy and insect be difficult for to produce advantages such as resistance, is one of valid approach of insect pests crop smothering.
Affirm (Merck Co.) is the biopesticide of using always, has the characteristics of super-high-efficient, low toxicity, noresidue and biopesticide such as nuisanceless.Compare with Avermectin, the insecticidal activity that not only shows as Affirm (Merck Co.) has improved 1～3 order of magnitude, active high to killing of the larva of lepidopterous insects and other many insects and mite class, the double again action of contace poison of existing stomach poison function, under low-down dosage, have good effect, and show as in the process of pest control, help integrated control insect to not injury of beneficial insect, enlarged insecticidal spectrum in addition, reduced toxicity people and animals.
Although Affirm (Merck Co.) is nontoxic, dissolving and the missible oil of dilution Avermectin is normal to adopt multiple synthetic high polymer, as benzinum etc.These synthesising biological macromolecules can retain in the environment midium or long term, and may constitute a threat to human health.Therefore, the emulsifier of natural degradable is the factor of the utmost importance of protection environment.
In addition, though Affirm (Merck Co.) has certain toxic action for cockroach, termite and ant, single application Affirm (Merck Co.) also cannot effectively be controlled the common insect in the family.It is former because Affirm (Merck Co.) can not have killing action to the insect ovum.At this moment since worm's ovum by the wax on chorion surface make it not to be subjected to the aminomethyl Avermectin kill, thereby insect can also further breed and fragmentation effect is had a strong impact on.
Summary of the invention
Primary and foremost purpose of the present invention is to overcome the shortcoming and deficiency that existing biopesticide can not effectively kill and wound worm's ovum, and a kind of biopesticide of energy killing ova is provided.
Another object of the present invention is to provide the preparation method of described biopesticide that can killing ova.
A further object of the present invention is to provide the application of described biopesticide that can killing ova.
Purpose of the present invention is achieved through the following technical solutions: a kind of biopesticide of energy killing ova, contain Affirm (Merck Co.), Escin and Ghana's seed oil;
The biopesticide of described energy killing ova, preferably contain following composition by mass percentage:
Affirm (Merck Co.) 0.08～0.3%
Escin 3～8%
Ghana's seed oil 3%
Polyol-based non-ionic surfactant 0.8～3%
CMC 1～3%
Water surplus;
The biopesticide of described energy killing ova, more preferably contain following composition by mass percentage:
Affirm (Merck Co.) 0.1%
Escin 5%
Ghana's seed oil 3%
Polyol-based non-ionic surfactant 1%
CMC 2%
Water surplus;
Described polyol-based non-ionic surfactant is preferably at least a in ethylene glycol, glycerine, pentaerythrite or the anhydrous sorbitol; The effect of polyol-based non-ionic surfactant is to form the good little drop of emulsification, and the penetration of Affirm (Merck Co.) is significantly strengthened.
The biopesticide of described energy killing ova also contains the height sweetener; The effect of height sweetener is an insect happiness food sweetener, and insects such as termite, ant and cockroach all have the habit that licks mutually, thereby cause the quick distribution of biopesticide of the present invention in population easily in pest population, improve insecticidal effect;
The consumption of described height sweetener is preferably mass percent 0.01%;
Described height sweetener is preferably at least a in Sucralose, saccharin sodium, honey element, An Saimi or the stevioside;
The preparation method of the biopesticide of above-mentioned energy killing ova, comprise following steps: Affirm (Merck Co.), Escin, Ghana's seed oil, polyol-based non-ionic surfactant and CMC are mixed, in the whipping process, add entry, form the emulsion of the little muddiness of homogeneous phase, obtain the biopesticide of energy killing ova;
The speed of described stirring is preferably 5000～10000 rev/mins;
