Description
Technical field
The invention belongs to synergetic pesticide composition field, the specific one kind that provides contains active constituent furan tebufenozide and seven fluorine
The synergetic pesticide composition of pyrethroids.
Background technology
Furan tebufenozide is the insecticide that China has independent intellectual property right, chemical name：N- (2,3-7- hydrogen -2,7- bis-
Methyl benzofuran .6- formoxyls)-N '-tertiary butyl .N ' (3,5 dimethylbenzoyl) hydrazine, furan tebufenozide, which is used as, to be contained
The N- tertiary butyl bishydrazide compounds of benzofuran ring, the moulting hormone regulation and control generally having with bishydrazide compounds
Effect.The main ingredient of insect moulting hormones is steroid hormone 20- hydroxyl ecdysones, this is specific in arthropod body
A kind of growth hormone.When 20- hydroxyl ecdysone concentration increases, larva enters the husking stage, and larva stops feed, epidermis at this time
Cell is recombinated, and by combining closely with ecdysone receptor albumen, activated receptor albumen contains multiple protein hydrolase
Ecdysial fluid enters husking space, and epidermal cell increases protein synthesis, generates new epicuticle and cuticula.When 20- hydroxyls are sloughed off
When skin element concentration reduces, insect growth enters the activating of enzyme in next stage, including ecdysial fluid, the digestion of preceding epidermis and ecdysial fluid
Re-absorption.With further decreasing for its concentration, completes the required other hormones of molting process and be released, therewith elder brother
Worm restores feed.
Tefluthrin (Tefluthrin) chemical name：2,3,5,6- tetra- fluoro- methylbenzyls (suitable)-(1RS, RS) -3- (2-
Chloro- 2,3,3- trifluoro propyl- 1- alkenyls) -2,2- dimethyl cyclopropane carboxylic acid's esters.Tefluthrin is to can be used as soil as first
The pyrethroid of insecticide, it is efficient to coleoptera, Lepidoptera and dipteral insect, it can be with granule, soil sprinkling or seed
The mode of processing is applied.Its volatility is good, can be fully migrated in the gas phase to prevent soil pests.Big Tanaka's half-life period about
It is one month, thus it can keep pest longer residual effect, and be unlikely to cause extended residual in the soil.
Prodenia litura (scientific name：Prodenia litura (Fabricius)) belong to the one of Lepidoptera Noctuidae spodoptera
A species, are a kind of crop pests, brown, and fore wing has many speckles, in have a canescence broad twill, therefore named twill
Noctuid.There are generation in various regions to prodenia litura at home, are a kind of binge pests, occur mainly in Jiangxi, the river of the Yangtze river basin
Soviet Union, Hunan, Hubei, Zhejiang, Anhui；The provinces such as Henan, Hebei, the Shandong of Yellow River basin.Its worldwide distribution, China except Qinghai,
Xinjiang is unknown outer, and each province (autonomous region) is found.Prodenia litura [1] is a kind of omnivorousness and binge pest, endangers host
Quite extensively, it in addition to brassicaceous vegetable, can also endanger including melon, eggplant, beans, green onion, leek, spinach and grain, industrial crops
100 sections of Deng Jin, 300 various plants.Food blade lower epidermis and leaf are nibbled with larva bite blade, bud, flower and fruit, first instar larvae
Meat only stays the transparent spot of epicuticle；Enter gluttony after 4 ages, bites blade, only stay master pulse.On packet cabbage, larva may be used also
Harm in leaf-head is pierced, sky is eaten in inside, and void excreta, pollutes, be allowed to reduce or even lose commodity value.
It is the effective way for solving resistance problem that the single use of pesticide, which can bring resistance risk, agriculture chemical compounding,.
It is one of prevention most effective chemical means of insect pest of the plant using chemical agent；With the novel pesticide of not cross resistance
It is a good solution to prevent insect pest of the plant；But one novel pesticide of exploitation needs to screen a chemical combination up to ten thousand at present
Object, hundred million dollars of cost 1.2-1.5, the development cycle is 5-10, it is difficult to the speed that the upper pest caught up with develops immunity to drugs；Others side
Method such as crop structure adjustment, different pesticide rotations etc., in actual mechanical process, it is difficult to play apparent effect.
Develop new product insecticide is expensive, the period is long, and in contrast, exploitation is efficient, less toxic, low-residual with research
Compounding have with mixture invest small, lead time it is short and by attention both domestic and external, it is numerous and confused to increase development dynamics.
The combination of furan tebufenozide and Tefluthrin has not been reported.

Specific implementation mode
(1), raw to survey embodiment
According to Sun Yunpei's Method, the synergistic effect of pharmacy mix is evaluated according to co-toxicity coefficient (CTC), i.e. CTC≤80 are association
Same antagonism, 80 ＜ CTC ＜ 120 are joint action of antagonism, and CTC >=120 are synergistic function.
Survey toxicity index (ATI)=(LC of standard agent50The LC of/reagent agent50)×100；
The virulence of the percentage composition+B medicaments of A medicaments refers in toxicity index × mixture of theoretical toxicity index TTI=A medicaments
The percentage composition of B medicaments in number × mixture；
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)]
×100。
1 furan tebufenozide of table measures (stomach toxicity work with Tefluthrin to the toxicity of wild cabbage prodenia litura (2 instar larvae)
Property, using leaching leaf stomach toxicity method, 72 hours after medicine, test method is with reference to the experiment of NY/T1154.14-2008 farm-chemical indoor determinations
The 14th part of criterion insecticide：Leaf dipping method).
The data result that table 1 is recorded shows furan tebufenozide and Tefluthrin mass fraction ratio 6:1~1:3 ranges
There is the interior stomach poison activity to wild cabbage prodenia litura (2 instar larvae) synergistic effect, co-toxicity coefficient to be more than 120；Furan tebufenozide with
Tefluthrin mass fraction ratio is 3:1~1:There is synergy to the stomach poison activity of wild cabbage prodenia litura (2 instar larvae) in 1 range
Effect, co-toxicity coefficient are more than 140；And furan tebufenozide and Tefluthrin mass fraction ratio are 20:1~10:1 and 1:6~1:
The stomach poison activity of 150 pairs of wild cabbage prodenia lituras (2 instar larvae) does not have synergistic effect, co-toxicity coefficient to be less than 120.
(2), example of formulations
4% furan tebufenozide Tefluthrin aqueous suspension agent
Take 1% Tefluthrin, 3% furan tebufenozide, 2% sodium lignin sulfonate, 1% urea, 4% aliphatic alcohol polyethenoxy
Ether is added deionized water and complements to 100%, active ingredient and other auxiliary agents are mixed, through sand in high speed shear dispersion, sand mill
After mill, high dispersive, the suspension system of stabilization are formed in water-medium, and it is outstanding to obtain 4% Tefluthrin furan tebufenozide water
Floating agent.
9% furan tebufenozide Tefluthrin microemulsion
Furan tebufenozide 6%, Tefluthrin 3%, ethyl acetate 8%, fatty alcohol polyoxyethylene ether 4%, isomery alcohol 3%,
Urea 3%, deionized water supplies 100%；Active ingredient is completely dissolved with solvent, emulsifier is then added, stabilizer, oozes
Saturating agent, antifreezing agent are uniformly mixed, and deionized water are eventually adding, after being sufficiently stirred, you can 9% seven fluorine of furan tebufenozide is made
Pyrethroids microemulsion.
(3), Application Example
2 4% furan tebufenozide Tefluthrin aqueous suspension agent of table prevents wild cabbage prodenia litura field control effectiveness test (after medicine
It investigates within 96 hours, is watered 45 kilograms per acre)
Table 2 the result shows that, 4% 22.5 grams/ha of furan tebufenozide Tefluthrin water suspension agent effective ingredient consumption
Preferably and better than 240 grams per liter methoxyfenozide aqueous suspension agents there is 96 hours investigation prevention effects after prevention wild cabbage prodenia litura medicine
