6, without poisoning：Poisoning is not will produce using crop.
Cartap (Cartap) belongs to nereistoxin and similar bionic insecticide, and the mechanism of action is that cartap invades insect god
Engaging portion through cell blocks the acetylcholine secreted by previous nerve cell and is communicated to latter nerve cell, to make nerve
Cells blocks are got in touch with, and are made insect neural paralysis, cannot be nibbled food, cannot take action, and stop development, so that dead.Cartap is used as killing
Worm agent, have many advantages, such as efficiently, wide spectrum, low toxicity, low-residual, there are interior suction, stomach toxicity, a variety of effects such as tag, also have food refusal,
The effects that ovicidal.Cartap knocks down soon pest, and the lasting period is long, desinsection wide spectrum, can prevent the snout moth's larva of rice, rice plant skipper, rice leaf mining
The pests such as fly, rice straw rope and vegetables cabbage caterpillar, pickles butterfly, oriental fruit months, citrus leaf-miner.There is special efficacy to the snout moth's larva of rice, and
Simultaneous the pests such as leafhopper, armyworm can be controlled, it is also effective to diamondback moth, striped flea-beetle.It is nontoxic to natural enemies such as spiders to birds low toxicity.It is right
Environmental organism lethality is small.
Since cartap is in agricultural production using for many years, pest produces certain drug resistance, and dosage also exists
Increase year by year.
Striped rice borer Chilo suppressalis (Walker) are that Occurrence the most serious is endangered on China's rice
One of, tillering stage it is aggrieved cause withered sheath, withered heart seedling, cause insect bite strain and dead ears ear period is aggrieved, the general time underproduction 8%~
10%, the underproduction is more than 3 one-tenth when serious.Domestic each rice region is distributed, wide compared with yellow rice borer and pink rice borer distribution, but mainly with the Changjiang river
Basin and on the south rice region occur heavier, it is in the situation that obviously rises that quantity occurs in recent years.Striped rice borer is in addition to hazard rice, moreover it is possible to
Endanger the weeds such as the crops such as wild rice stem, corn, sorghum, sugarcane, rape, broad bean, wheat and reed, barnyard grass, Leersia Sw.
Striped rice borer is not only the important pests in China's Rice Production, and in external paddy fields, distribution is also very wide, for example,
The harm of the striped rice borer such as Korea, Japan, Philippine, Vietnam, Thailand, Malaya, Indonesia, India, Egypt is also very tight
Weight.
Invention content
The object of the present invention is to provide it is a kind of it is efficient to rice-stem borer insecticidal activity, lasting effect is long, quick-acting is fast, low

Cartap is 40 grams of effective ingredient/mus to the recommended dose of rice-stem borer, and on this basis, experimental design proportioning is 1: 1,1:
2,1: 5,1: 10,1: 20,1: 30,1: 40,1: 50,1: 60,1: 70,1: 80 totally 11 processing, separately set ethyl pleocidin, kill snout moth's larva
Red two single doses processing.
It tests medication and uses ethyl pleocidin active compound and cartap active compound, dissolved active compound using solvent, according to setting
Matched proportion density, it is spare to be configured to required concentration liquid.
The method of indoor biometrics is：Using capillary micro intravenous drip method, capillary micro intravenous drip device volume is 1.0 μ L.With
Micro intravenous drip device is by liquid by head drop in the back side of 3 instar larvae of striped rice borer, 30 larvas of each concentration processing, every 5 larvas
It is put into the culture dish of an a diameter of 9cm, a small amount of feed is for feeding built in ware, separately as a contrast with 30 larvas of acetone drop.
Larva after processing is still placed in receptacle, and the death rate is checked after 48h.Data are handled with SPSS software statistics.Find out virulence
Regression equation, the lethal concentration of 50, related coefficient etc., are used in combination Sun Yunpei's Method to find out co-toxicity coefficient.
The co-toxicity of mixture preparation is indicated using the co-toxicity coefficient method of Sun Yunpei：
Theoretical toxicity index TTI=Σ (medicine effective ingredients of the toxicity index ATI of certain medicine × in mixture of mixture preparation
Percentage).
Synergistic effect criterion after two kinds of effective ingredient compoundings：
CTC is synergistic effect when being more than 120, is antagonism when being less than 80, is addition when 80~120.
It is 5.68 μ g/mL to the lethal concentration of 50 of striped rice borer that experiment, which determines ethyl pleocidin, and setting ethyl is sterilized more
Element is 100 to the toxicity index of striped rice borer.Toxicity index, co-toxicity coefficient such as following table of each processing to striped rice borer：
1 ethyl pleocidin of table, cartap different ratio are to the toxicity test result of striped rice borer
When analyzing above-mentioned data result and showing that ethyl pleocidin and cartap are compounded by different proportion, except No. 1, No. 2 are matched
Side is outer, and the co-toxicity coefficient of remaining compounded formula is all higher than 120, shows to all have apparent synergistic effect.Illustrate two kinds effectively
After part compounding, there can be good synergistic effect.With the increase of ethyl pleocidin in proportioning, synergistic effect is in significantly rise
Trend.When the ratio of ethyl pleocidin and cartap be 1: 20 when, co-toxicity coefficient reaches 220.65, in all formulas most
It is high.When ratio of the ethyl pleocidin in compounding continues growing, co-toxicity coefficient is gradually reduced, and synergistic effect reduces.Work as second
When the ratio of Quito bacteriocidin and cartap is 1: 1, co-toxicity coefficient further declines, and synergistic effect further decreases.
We select following proportioning to carry out trial-manufacture of sample thus, and have carried out field control effectiveness test.
Below with specific example of formulations to present invention be described in more detail, but the present invention be only limited to absolutely not it is following
These embodiments.Percentage is weight percentage in formula.
Embodiment 2：30% ethyl pleocidin cartap wettable powder
Embodiment 3：The 50% solvable pulvis of ethyl pleocidin cartap
Embodiment 4：60% ethyl pleocidin cartap suspending agent
Embodiment 5：30% ethyl pleocidin cartap aqua
Embodiment 6：20% ethyl pleocidin cartap wettable powder
Embodiment 7：80% ethyl pleocidin cartap water dispersible granules
By above six embodiments made from ethyl pleocidin and the various different ratios of cartap, prevention rice two is carried out
Change the field control effectiveness test of snout moth's larva, while passing through the effect with 60 grams per liter ethyl pleocidin suspending agents, the solvable pulvis of 50% cartap
Fruit compares, the synergistic effect after verification compounding.Test site is the Jiangsu Province Xiangshui County ports Chen Jia bight village, and the time is 2015 8
The moon 12, experiment totally eight processing, a blank control each handle three repetitions, cell random alignment, plot area 9*
5m2, the planting habits of all cells is identical as local planting habit.
Investigation standard is：By 5 point samplings, random 5 points of samplings per cell, every is investigated 5 clumps, totally 25 clumps.Before dispenser
The Chilo spp larvae quantity for investigating 25 clumps of rice respectively with the 1st, 7,15 day after dispenser, records each instar larvae number, calculates insect population and subtracts
Move back rate, control effect.Specific data (data are the average value of three repetitions) are as follows：
Table：The field control effectiveness test result of ethyl pleocidin, cartap single dose and complex preparation to rice-stem borer
As can be seen from the above data, under using identical effective ingredient dosage, ethyl pleocidin and cartap are not
After proportioning compounding, Revision insect recluced rate, control effect will be apparently higher than two kinds of single doses, and all formulas have apparent synergy to make
With.When cartap content is high in formula, quick-acting is preferable, and lasting effect is general, when ethyl pleocidin content is high in formula,
Quick-acting is general, and lasting effect is preferable, this result also really reflects the characteristic of the two medicaments.Compared with single dose, ethyl is more
Bacteriocidin improves control effect with each complex preparation of cartap, extends the lasting period, reduces times for spraying, alleviates peasant
The amount of labour reduces peasant's drug cost, there is preferable economic benefit.
