Description
Technical field
The present invention relates to a kind of pesticidal preparations for preventing and treating beet armyworm, and in particular to a kind of containing biological pesticide rotenone
Insecticide pesticide preparation and the preparation method and application thereof, belongs to technical field of pesticide.
Background technique
Beet armyworm (Spodoptera exigua) belongs to Lepidoptera Noctuidae, is a kind of universal polyphagy weight
Agricultural pests are wanted, are distributed from 40 °~57 ° to 35 °~40 ° of south latitude of north latitude, in Asia, North America, Europe, Australia and Africa
There is record of causing harm, 35 section 108 such as main harm vegetables, cotton, peanut, tobacco, corn and soybean belongs to 138 kinds of crops, especially with vegetable
Dish is aggrieved most heavy.Before the 1980s, beet armyworm only occurs in China some areas, a in China more than 20 at present
Provinces, municipalities and autonomous regions occurring and damage, the ground such as region overlay south China, East China, Central China, North China, southwest and northwest have reached the Liao Dynasty northernmost
The Shenyang City Ning Sheng.Between 1979-2008 years, China beet armyworm breaks out frequency and wave ascendant trend is presented, and it is flat to break out index
Equal annual increasing rate is 0.076.After beet armyworm in 1997 after Henan, Hebei, Shandong, the big generation in Anhui, and in 1999
In the Yellow River and Huai He River, Yangtze-Huaihe River Valley, wildness is caused disaster once again, and occurring area is big, the height of insect density, the heaviness of loss, is that history is rare
See.Since its harm is serious, chemical pesticide is largely used when forcing prevention and treatment, causes development of drug resistance rapid, at present to organic
The multiclass insect growth regulator, IGR insecticides such as Phosphorus, pyrethroid, carbamates produce the anti-of higher level
Pharmacological property seriously threatens agricultural product production safety, quality safety and ecological safety.
Rotenone (rotenone) is one of three great tradition botanical pesticide, has strong performance of tagging to insect,
There is preferable bioactivity to 800 various pests, it is especially prominent to aphid mite pest effect, be it is anti-eliminate aphis, aphid, vegetable powder
The special effect agent of butterfly and citrus red mite.Rotenone is existing to be classified as 21 century by State Development Planning Commission and the Department of Science and Technology and preferentially sends out
Exhibition industry is environment friendly agricultural recognized in the world.Especially on the industrial crops such as vegetables, fruit tree, tealeaves directly eaten
It uses, its more aobvious advantage can not only produce quality-assured vegetables, trust fruit, trust tea, and can also improve crop quality, improve mouth
Sense, is the ideal medication in green agricultural product base.Rotenone is a kind of very with the plant insecticide of Development volue.It is optional
Selecting property inhibits nerve fiber and musculature, no absorbability, have it is strong tag, stomach toxicity has both certain repellent, food refusal and suppression
Growth and development effect processed.Its insecticidal action is slow, but insecticidal action is more lasting, can maintain 10 days or so.Insecticidal rotenone activity
Height, insecticidal spectrum is wide, and being currently known it has a preventive effect to 15 Ge Mu137Ge section, 800 various pests, predominantly Lepidoptera, Homoptera, double
Wing mesh, coleoptera, Hymenoptera.Rotenone is classified as 21 century Preferential Developmental Industry by State Development Planning Commission and the Department of Science and Technology,
It is environment friendly agricultural recognized in the world.It is especially used on the industrial crops such as vegetables, fruit tree, tealeaves directly eaten, more
Its advantage is shown, quality-assured vegetables can not only be produced, fruit is trusted, trust tea, and crop quality can also be improved, mouthfeel is improved, is green
The ideal medication of color agricultural products base.
Ring tebufenozide (chromafenozide) is a kind of novel insect growth regulator, IGR, belongs to diacyl hydrazine chemical combination
Object.Ring tebufenozide causes to imitate by the husking that its hormonal activity destroys insect.Such hormonal activity is by juvenile hormone and sloughs off
Skin hormone is adjusted simultaneously, generates fatefulue husking so as to cause insect.It is indoor to show ring tebufenozide pair with field trial
Hazard rice, vegetables, fruit tree, tea tree and the lepidoptera pest of other crops larva there is outstanding control action.It is not only right
Plant safety does not have phytotoxicity, and does not have adverse effect to environment and ecology, is ideal medicine in comprehensive evil object improvement system
Agent.
But the single formulation of above rotenone preparation and ring tebufenozide encounters the problem of series in actual use.
Such as rotenone preparation in the use of field rotenone easily in the natural environment easily occur photodissociation, hydrolysis, make rotenone drug effect,
Lasting effect is affected, and certain influence is received to the control efficiency of pest.A kind of change of the ring tebufenozide as new listing
It learns to farm medicine, there is preferable control efficiency to aphid at present, but in order to improve medicament to the control efficiency of aphid, peasant is continuous
Ground improves the dosage of medicament, and in addition aphid easily generates resistance to medicament.

The roundleaf piece that diameter 1.5cm is broken into punch, impregnates 10s in medical fluid respectively, dries on blotting paper after taking-up, then put
Entering 24 holes to support in worm plate, 2, every hole leaf, and accesses 3 instar larvae of standard 1, every processing is repeated 3 times, 10 test worms of every repetition, with
Clear water compares.Rest the feeding worm that worm plate is placed in 27 ± 1 DEG C of temperature, relative humidity is 50% -75%, photoperiod 14L: 10D
In, inspection result after 48h is handled, nonresponder is touched with tweezers and is considered as death, and record experimental result, calculates the death rate,
Toxicity regression line is drawn, LC is calculated50Value.The co-toxicity coefficient of mixture is calculated using Sun Yunpei's Method.Co-toxicity coefficient CTC=100 × reality
The mixed toxicity index of the mixed toxicity index/theory in border.When co-toxicity coefficient is significantly greater than 100, show there is synergistic effect；It connects
Nearly 100, indicate summation action；It is significantly less than 100, shows there is antagonism.Test and calculated result are as shown in table 1:
The The Toxicity Determination result (for 24 hours) of 1 single dose of table and mixture to 3 instar larvae of beet armyworm
As can be seen from Table 1, rotenone, ring tebufenozide, rotenone and each proportion mixture of ring tebufenozide are to beet armyworm 3
The lethal concentration of 50 LC of instar larvae50Value sequentially (5:1,2.5:1,1:1,1:2.5 and 1:5) be respectively 22.48,10.08,15.43,
12.88,10.07,7.93 and 7.60 μ g/mL；Rotenone and ring tebufenozide it is each proportion mixture co-toxicity coefficient sequentially (5:1,
2.5:1,1:1,1:2.5 and 1:5) it is respectively 120.92,129.12,138.12,150.78 and 145.94.Rotenone and ring worm acyl
Hydrazine proportion is that 5:1,2.5:1,1:1,1:2.5 and 1:5 have synergistic effect, wherein synergistic effect is most obvious when proportion is 1:2.5.
Embodiment 16: mixed insecticide field control effectiveness test
