Abstract
A composite insecticide in the form of emulsified oil or microemulsion for preventing and eliminating tobacco aleyrodids is proportionally prepared from melarrhizin, abameotin, solvent, emulsifier, and other assistants including co-solvent, synergist, or optional anti-freezing agent.
Description
Technical field
The present invention relates to a kind of biological insecticides, specifically, relate to the compounded pesticides of a kind of destruxins and Avermectin.
Background technology
Destruxins (destruxin) is the secondary metabolite of insect pathogenic fungus-green muscardine fungus (Metarhiziumanisopliae var.anisopliae), is the important virulence factor of green muscardine fungus.Destruxins has desinsection, biologically active such as antiviral and anticancer, and has the brand-new mechanism of action that is different from existing insecticide and the easy feature of degraded and noresidue, and the development and use destruxins has important economic implications.Destruxins A, B, E distribute the extensivelyst, and the destruxins that content is the highest has good control efficiency to aphid, Bemisia tabaci, diamond-back moth etc., has a good application prospect.
Avermectin (abamectin) is present widely used high-efficient broad-spectrum insecticide, is mainly used in important pests such as control diamond-back moth, Bemisia tabaci and liriomyza bryoniae, and still, insect has also been developed into a major issue to the Avermectin pesticide resistance.Adopting the agriculture chemical compounding technology or mixing application technique is to overcome or delay a drug-fast important method, and therefore, the Compositional type insecticide of exploitation Avermectin is significant.
Summary of the invention
The Compositional type insecticide that the purpose of this invention is to provide a kind of destruxins and Avermectin.
The compounded pesticides of a kind of destruxins and Avermectin is made up of host and assistant agent, and its percentage by weight is a host 0.5～5%, assistant agent 95～99.5%; Described host be destruxins A, destruxins B or destruxins E any or any two or three kinds mixture and Avermectin weight ratio be 1: 19～40 mixture.
As preferably, the preferred weight ratio of destruxins and Avermectin is: destruxins: Avermectin=1: 19～29.
This compounded pesticides can be made into the formulation of various needs.Missible oil formulation (EC) for example, the assistant agent of this moment is solvent, emulsifier and other assistant agent, its weight ratio is 50～99: 1～50: 0～5.Described solvent is acetone, methyl alcohol, ethyl acetate, carrene and arene etc.; Described emulsifier is nonionic, anion or nonionic and anionic compound surfactant; Described other assistant agent is meant cosolvent or synergist or its mixture.Preferred benzene,toluene,xylene of described arene or ethylbenzene.
Perhaps make micro emulsion formulation (ME), the assistant agent of this moment is solvent, emulsifier, other assistant agent and water, and its weight ratio is: solvent: emulsifier: other assistant agent: water=1～20: 5～60: 0～20: 20～90.Described solvent is arene or ester class, and described emulsifier is nonionic, anion or nonionic and anionic compound surfactant; Described other assistant agent is antifreezing agent, cosolvent or synergist.Preferred benzene,toluene,xylene of described aromatic hydrocarbon solvent or ethylbenzene, described esters solvent ethyl acetate, methyl formate or Ethyl formate.
Compared with prior art, Compositional type insecticide of the present invention has following beneficial effect: (1) has synergistic effect, and composite dose co-toxicity coefficient is greater than 120.(2) help delaying pest resistance to insecticide and produce, the insect of antagonism Avermectin is effective.(3) price a little less than or be not higher than existing kind.
Embodiment
The preparation of embodiment 1:1% destruxins and abamectin emulsifiable concentrate (EC) preparation
The mass ratio of each component is: destruxins A0.1%, Avermectin 0.9%, solvent 80%, emulsifier 19%.
Compound method: first weighing solvent is dissolved in destruxins A and Avermectin in ethyl acetate and the toluene respectively in container then, adds emulsifier again, fully stirs evenly the back packing.
The preparation of embodiment 2:2% destruxins and abamectin emulsifiable concentrate (EC) preparation
The mass ratio of each component is: destruxins 0.1%, Avermectin 1.9%, solvent 90%, emulsifier 8%.
Compound method: first weighing solvent takes by weighing thick destruxins and Avermectin then respectively and is dissolved in the solvent in container, adds emulsifier again, fully stirs evenly the back packing.
The green stiff avermectin micro-emulsion of embodiment 3:3% (ME)
The mass ratio of each component is: destruxins 0.1%, Avermectin 2.9%, solvent 8%, emulsifier 15%, water 74%.
Compound method: first weighing solvent is dissolved in destruxins and Avermectin in the solvent respectively in container then, adds emulsifier again, makes preparation become the solution of homogeneous transparent after fully stirring evenly, and packs then.
Embodiment 4: mixture is to the Toxicity Determination of Bemisia tabaci (Bemisia tabaci)
During Toxicity Determination, make test plant with Japan (Hibiscus rosa-sinensis L.), its potted plant seedling is educated in dependent insect cage, Bemisia tabaci adults is inserted dependent insect cage, treat after it was laid eggs one day it all to be driven out of, keep 26 ℃ temperature and 14: 10 illumination in the cage, treat that Bemisia tabaci on Japan's blade grows to 2 ages during nymph, adopt infusion process to carry out the virulence test, repeat 4 times, 4 days effect behind the investigation medicine, the calculation correction lethality, ask the regression equation of drug concentration logarithm-lethality probability value, and the comptibility test of the side of card, obtain LC then
50, calculate the co-toxicity coefficient (CTC) of relative virus force index (TI) and intermixture with reference to the abundant method of Sun Yun.Its result of the test such as table 1 when destruxins A or thick destruxins and Avermectin are mixed, have synergistic effect.
The green stiff Avermectin of table 1 is to the Toxicity Determination of Bemisia tabaci (behind the medicine 4 days)
