In order to confirm ethyl pleocidin and dimehypo mixture, be with synergistic effect, summation action or antagonism,
We have carried out recipe determination research to ethyl pleocidin and dimehypo first, and the object of indoor biometricses is set in China's water
The striped rice borer of most serious is endangered in rice production, specific test situation and result are as follows：
Experiment medication uses 95% ethyl pleocidin active compound and 42% dimehypo mother's medicine, is dissolved active compound using solvent,
According to the matched proportion density of setting, be configured to needed for concentration liquid it is standby, used dimehypo mother medicine is voluntarily produced by our company,
Ethyl pleocidin and auxiliary agent are outsourcing.
The method of indoor biometricses is：Using capillary micro intravenous drip method, capillary micro intravenous drip device volume is 1.0 μ L.With
Micro intravenous drip device by decoction by head drop in the back side of the instar larvae of striped rice borer 3, each concentration handles the larva of 30 or so, every 5
Head larva is put into a diameter of 9cm culture dish, and a small amount of feed built in ware supply feeding, separately by the use of 30 larvas of acetone drop as
Control.Larva after processing is still placed in receptacle, and the death rate is checked after 48h.Data are handled with SPSS software statistics.Obtain
Toxicity regression formula, the lethal concentration of 50, coefficient correlation etc., and obtain co-toxicity coefficient with the abundant methods of Sun Yun.
The co-toxicity of mixture preparation is represented using Sun Yunpei co-toxicity coefficient method：
Theoretical toxicity index TTI=Σ (medicine effective ingredients of the toxicity index ATI of certain medicine × in mixture of mixture preparation
Percentage).
CTC is synergistic effect when being more than 120, is antagonism during less than 80, is addition when 80~120.
The ethyl pleocidin of table 1, dimehypo different ratio are to the toxicity test result of striped rice borer
Analyze above-mentioned data result to show, when ethyl pleocidin is compounded with dimehypo by different proportion, except A:B is 50:1
With 60:Outside 1 proportioning, the co-toxicity coefficient of all compounded formulas is all higher than 120, shows to be respectively provided with obvious synergistic effect.Explanation
After two kinds of effective part compoundings, there can be good synergistic effect.Wherein proportioning 4, the co-toxicity coefficient of proportioning 5 are even more to be more than 200,
For highest in all proportionings.
In order to verify the practical application effect of above formula, we carry out trial-manufacture of sample of knowing clearly from following proportioning,
And field control effectiveness test is carried out.
Below with specific example of formulations to be further described the present invention, but the present invention be only limited to absolutely not it is following
These embodiments.Percentage is weight percentage in formula.
Embodiment 1：30% ethyl pleocidin dimehypo wettable powder
Embodiment 2：50% ethyl pleocidin dimehypo water dispersible granules
Embodiment 3：30% ethyl pleocidin dimehypo suspending agent
Embodiment 4：50% ethyl pleocidin dimehypo water solution
Embodiment 5：11% ethyl pleocidin dimehypo suspending agent
Embodiment 6：80% ethyl pleocidin dimehypo water dispersible granules
By six embodiments of the above made from ethyl pleocidin and the various different ratios of dimehypo, carry out preventing and treating rice two
Change the field control effectiveness test of snout moth's larva, while pass through the effect with 60 g/l of ethyl pleocidin suspending agents, the solvable aqua of 29% dimehypo
Fruit contrasts, the synergistic effect after checking compounding.Test site is Jiangsu Province Xiangshui County Chen Jia Gang Hexin villages, and the time is 2015 7
The moon 15, 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 with the planting habit of locality.
Investigation standard is：By 5 point samplings, random 5 points of samplings per cell, every is investigated 5 clumps, totally 25 clumps.Before dispenser
With the 1st, 7,15 day after the dispenser Chilo spp larvae quantity for investigating 25 clumps of rice respectively, each instar larvae number is recorded, insect population is calculated and subtracts
Move back rate prevention effect.Specific data (data are the average value of three repetitions) are as follows：
Table 2：The field control effectiveness test result of ethyl pleocidin, dimehypo 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 dimehypo are not
After proportioning compounding, Revision insect recluced rate, prevention effect will have obvious synergy to make apparently higher than two kinds of single doses, all formulas
With.Revision insect recluced rate, prevention effect between each formula, without notable difference.When dimehypo content is high in formula, quick-acting compared with
Good, lasting effect is general, and when ethyl pleocidin content is high in formula, quick-acting is general, and lasting effect is preferable, and this result is also true
The characteristic of the two medicaments is reflected in fact.Find out from upper table data, complex preparation preventive effect of 7 days after medicine is higher than after medicine 1 day
Preventive effect, the preventive effect of 15 days is greater than the preventive effect of 7 days after medicine after medicine.Compared with single dose, complex preparation extends the lasting period, reduces
Times for spraying, alleviates peasant's amount of labour, reduces peasant's drug cost, there is preferable economic benefit.
