Abstract
A composition as agricultural chemical suitable for fruit tree, vegetables, cotton, rice, corn and tobacco to kill pests and mites is prepared from evericin, imidacloprid, carrier and auxiliaries through mixing. It features higher biologic activity and poisoning power to pests, less consumption, high safety, no damage to natural enemy, people and livestoke, long active period and low cost.
Description
The present invention relates to composition pesticide, particularly a kind of with Avermectin and Imidacloprid as composition pesticide of main active and preparation method thereof.
In the present prior art, Avermectin is the antibiotic insecticide by microbial fermentation, Imidacloprid is the insecticide by chemosynthesis, they have similar insecticidal spectrum, the otherness that the control key object is also arranged, Avermectin be based on control lepidoptera pest, evil mite and wood louse, double homoptera pest such as eliminate aphis, Imidacloprid is mainly with insects such as control rice fulgorid, aphid and leafhopper, and is invalid to lepidoptera pest and evil mite.Avermectin mainly shields, no systemic activity, and the longevity of residure is short, and Imidacloprid has strong systemic action, the longevity of residure is long.There is greatest differences in both chemical constitutions, and action target is also different separately.Avermectin mainly acts on insect neurotransmitter GABA, suppresses neurotransmission, and Imidacloprid acts on insect associating caudacoria and Ach receptors bind.
The purpose of this invention is to provide a kind of is the composition pesticide of main active ingredient with Avermectin and Imidacloprid.
Another object of the present invention provides a kind of preparation method of above-mentioned composition pesticide.
Contain drug component, farm chemical carrier and adjuvant in the composition pesticide of the present invention, the parts by weight proportioning of described each component is:
Drug component 0.1-35 part
Farm chemical carrier 50-98 part
Adjuvant 1-25 part
Wherein, contain Avermectin and Imidacloprid in the described drug component, and the parts by weight proportioning of the two is 1: 4-99 part.
Described Avermectin raw material can be the former medicine of powdery, syrupy shape concentrate or mother liquor.
Described Imidacloprid raw material can be the former medicine of powdery.
Described farm chemical carrier can be inert dust or organic solvent; Inert dust such as potter's clay, diatomite, talcum powder, white carbon, kaolin can mix use separately or with any ratio; Organic solvent such as toluene, dimethylbenzene, dimethyl formamide, light diesel fuel aromatic hydrocarbons, petroleum aromatic can mix use separately or with any ratio.
Described adjuvant is the material that has the material of wetting action or have emulsification.Described material with profit temperature effect can be vegetable oil, Chinese honey locust, alkylbenzenesulfonate, draws back powder, multiple nonionic surface active agent, can mix use separately or with any ratio; Described material with emulsification is aryl polyoxy ethyl ether, arylsulphonate, can mix use separately or with any ratio.
The preparation method of composition pesticide of the present invention comprises two kinds of active ingredient Avermectin and Imidacloprid and selected farm chemical carrier, adjuvant ratio is in accordance with regulations mixed that stirring gets final product.
Composition pesticide of the present invention has quite high biologically active, adopts conventional co-toxicity coefficient (C.T.C) comparison method to judge proof, and Imidacloprid and Avermectin increase significantly by the composite virulence to pest of certain proportioning, i.e. C.T.C＞＞100; Composition pesticide LC of the present invention
50=0.17.The consumption of composition pesticide of the present invention is lower.
Composition pesticide of the present invention uses fool proof, and natural enemy, men and cattle are not had injury effect, also can preserve the ecological environment, so both carry out the composite complementarity widely that has.Get length separately, mend weak point each other, thirst for improving the double effect of controlling of Avermectin, enlarge the controlling object of Imidacloprid, prolong the Avermectin longevity of residure, delaying drug resistance produces, and reduces production costs, and increases economic efficiency.
Composition pesticide of the present invention can be widely used on the crops such as fruit tree, vegetables, cotton, paddy rice, corn, tobacco leaf, can prevent and treat all kinds of resistant insects, evil mite.
Further describe the present invention below in conjunction with embodiment, yet the present invention is not limited to these embodiment.
Embodiment 1
With purity is that 4.5 parts in 91% Imidacloprid powder is dissolved among 82 parts the DMF, add purity and be after 0.5 part in 95% Avermectin powder stirs, mix 7.5 parts of 2204 (Nanjing petrochemical industry products), 5.5 parts of vegetable oil, the back coarse filtration that stirs, packing obtains the missible oil finished product.
Comparative Examples 1-4 operates similarly to Example 1, obtains the missible oil product of proportioning shown in the table 1.
Table 1
Wherein, described DMF is commercially available organic solvent code name; 2204 is the commercially available wetting composition of agricultural chemicals.Comparative Examples 1 is Avermectin: the ratio of Imidacloprid is brought up to 1: 4, similarly obtains missible oil.Comparative Examples 2 is Avermectin: the ratio of Imidacloprid is brought up to 1: 2, similarly obtains missible oil.3 of Comparative Examples add Imidacloprid and carrier and adjuvant, similarly obtain missible oil.Comparative Examples 4
| Composition Comparative Examples 1 Comparative Examples 2 Comparative Examples 3 Comparative Examples 4 Imidacloprids, (91%) 2.0 1.0 1.0 0.0 AVM, (95%) 0.5 0.5 0.0 1.0 DMF 85 86 86.5 86.5 2,204 7777 vegetable oil 5.5 5.5 5.5 5.5 |
Only add Avermectin and carrier and adjuvant, similarly obtain missible oil.
The present invention selects the remarkable synergistic effect of proportioning to be illustrated with following test, and the composition pesticide that therefrom can draw Avermectin of the present invention and Imidacloprid increases significantly to the virulence of pest.
Test concentration (LC in 1 semilethal
50)Mensuration.Determination object is the aphis craccivora on the broad bean seedling (cotyledon period) of indoor feeding, to try under 25 ℃ of temperature, to get food after worm adopts conventional infusion process to handle and raise 48 hours check results, calculate lethality and corrected mortality, obtain the virulence regression equation (y=a+bx) that each is handled respectively with method of least squares, calculate the LC that each is handled
50Value.The judgement of synergistic effect adopts conventional co-toxicity coefficient (C.T.C) comparison method to judge.
The Sun.Y.Cet computing method:
1
The results are shown in Table 2 table 2 sample virulence regression equation LC
50The value co-toxicity coefficient
(Y=A+BX) (ppm) C.T.C sun.C.Yet embodiment 1 Y=6.25+1.99X 0.17 852 Comparative Examples 1 Y=5.96+1.59X 0.25 440 Comparative Examples 2 Y=4.49+2.33X 1.07 77 Comparative Examples 3 Y=4.24+2.38X 2.10/Comparative Examples 4 Y=5.53+1.26X 0.38/
Can prove that from the result of table 2 of the present invention is that the proportioning of the composition pesticide of main component has more significant synergistic effect with respect to other mix proportions with Avermectin and Imidacloprid.
Test 2 effect experiments
Test is carried out in the somewhere, Shandong Province, and kind is 30 years living kinds of pear, and mu is planted 18 strains, and it is good to carry training management, the tree vigo(u)r stalwartness, and medium laying particular stress on takes place in pear sucker.5000 times, 8000 times, 10000 times of missible oil product dilution of embodiment 1 are established in test, are standard control for 5000 times with Comparative Examples 4 and the dilution of 10% imidacloprid wettable powder, and the spray clear water is a blank.Respectively investigated 1 time borer population alive after the medication in 3 days, 7 days, 10 days and 15 days, calculate insect population go down rate and corrigendum preventive effect with following calculating formula, and carry out significance test.
