The water-dispersible grain agent prescription
Rice-stem borer (Chilo suppressalis) popular name borer, borer, moth stalk worms etc. are the formidable opponents of paddy rice.Larva moth food stem stalk causes the withered heart, and striped rice borer has the strain of commentaries on classics harm habit, and a Chilo spp larvae can endanger many strains paddy rice, causes dead leaf sheath, the withered heart.If untimely control, the field a lot of withered heart seedlings occur through regular meeting, and part field piece is not is not prevented and treated striped rice borer because of nursery period, and field withered heart seedling ratio is up to 30% now, and part location, field withered heart seedling ratio surpasses 50%, causes very big loss.Ethyl multiple killing teichomycin, butene-fipronil are two kinds of compositions that insecticidal activity is very high, according to their the effect characteristics and mechanism of action, the object of indoor biometrics are decided to be rice-stem borer (Chilo suppressalis).
The method of indoor biometrics is: adopt capillary trace drop method, capillary trace dropper volume is 1.0 μ L.With micro-dropper soup is pursued a drop in the back side of striped rice borer 6 instar larvaes; Each concentration is handled about 30 larva; The culture dish that it is 9cm that per 5 larvas are put into a diameter, the built-in a small amount of feed of ware supplies to get food, in addition with 30 larvas of acetone drop as contrast.Larva after treatment still is placed in the receptacle, checks lethality behind the 48h.Data are handled with the SPSS software statistics.Obtain toxicity regression formula, the lethal concentration of 50, correlation coefficient etc., and obtain co-toxicity coefficient with the abundant method of Sun Yun.
The co-toxicity of mixture preparation adopts the abundant co-toxicity coefficient method representation of Sun Yun:
The theoretical toxicity index A=∑ of mixture preparation (toxicity index of certain medicine * percentage of this pharmaceutically active ingredient in mixture).
C was synergistic effect greater than 120 o'clock, less than 80 o'clock be antagonism, 80～120 o'clock is addition.
Compounding method of preparation according to above-mentioned suspending agent, wetting powder and water dispersible granules; According to the content of former medicine what; Select suitable formulation; Preparation ethyl multiple killing teichomycin content is selected wherein representational prescription to give birth to survey and is tested, and compare with 10% ethyl multiple killing teichomycin and 10% butene-fipronil at 1%-30% and the complex preparation of butene-fipronil content at 1%-40%.
The different proportionings of table 1 are to the toxicity test result of striped rice borer
Analyze above-mentioned data, measure the result and show, when ethyl multiple killing teichomycin and butene-fipronil different proportion were composite, the co-toxicity coefficient of all compounded formulas all had obvious synergistic effect respectively all greater than 120.Explanation with two kinds of active ingredients composite after, good synergistic effect can be arranged.Through the indoor biometrics test, select the field trial that the bigger prescription of CTC three, prescription four and the less prescription eight of CTC are prevented and treated rice-stem borer, confirm the effect of prescription control striped rice borer; Simultaneously through with the effect comparison of ethyl multiple killing teichomycin, the agent of butene-fipronil list, verify the synergistic effect after composite.Concrete test method and data are following:
Test one: 9% ethyl multiple killing teichomycin butene-fipronil SC, 4% ethyl multiple killing teichomycin butene-fipronil SC, 31% ethyl multiple killing teichomycin butene-fipronil WDG, 10% ethyl multiple killing teichomycin SC, 10% butene-fipronil SC and do the test of field control striped rice borer; The test place is that Hanchuan City Liu of Xiaogan Prefecture, Hubei Province is at a distance from the town; Time is on July 10th, 2011, test totally four processing, and each handles three repetitions; The sub-district randomized arrangement, sub-district area 95m
2, the planting habit of all sub-districts all planting habit with local is identical, and is record dispenser same day and all synoptic data thereafter, specific as follows:
Table 2 duration of test meteorological data
The investigation standard is: 7d gets killed strain 50 strains at random behind the medicine in each sub-district, and the life or death number of bat dish method metering nymph calculates lethality; 150 clumps of parallel sampling method samplings are adopted in 15d, the every sub-district of 25d behind the medicine, investigate withered calculation, calculate withered heart rate and seedling protecting effect at last.Specifically data (data are the mean value of three repetitions) are as follows:
Table 3 9% ethyl multiple killing teichomycin butene-fipronil SC and other compounded formulas are to the field control effectiveness test of striped rice borer
Annotate: data are the mean value that repeats for 3 times in the table, and letter is all Duncan testing differentia remarkable time mutually: in July, 2011 place: the Hubei Xiaogan
Can find out from above data; Under the situation of identical using dosage, 9% ethyl multiple killing teichomycin butene-fipronil SC (prescription three) 25d control rate behind medicine is that the 25d control rate reaches 90.02% to 87.89%, 4% ethyl multiple killing teichomycin butene-fipronil SC (prescription four) after medication; For using single agent of 10% ethyl multiple killing teichomycin SC and the single agent of 10% butene-fipronil SC; The effect that two kinds of composite preventive effects are higher than single agent far away when using, difference is extremely remarkable, and 31% ethyl multiple killing teichomycin butene-fipronil WDG (prescription eight) 25d after medication; Its preventive effect is 79.43%, and prescription three and fill a prescription evident difference is arranged between four.
Through above-mentioned three field control effectiveness tests; The effect that can find out prescription three, prescription four control striped rice borer is best; And fill a prescription eight control efficiency and the prescription three and the comparatively evident difference of having ideals, morality, culture, and discipline of filling a prescription; This also with the result of indoor biometrics match (CTC is big more, and synergistic effect is big more) and the two significant difference.Simultaneously, four preventive effects of filling a prescription are superior to filling a prescription three, and fill a prescription four former medicine usage amounts still less, so think that prescription four is best, the most economical proportionings of effect, the single agent with respect to ethyl multiple killing teichomycin and butene-fipronil has stronger synergistic effect.
Through above-mentioned three field control effectiveness tests, can confirm to fill a prescription four for the more suitable prescription of control striped rice borer, this prescription has been carried out further test, filter out the optium concentration of control striped rice borer.
Test the experiment of two: 4% ethyl multiple killing teichomycin butene-fipronil SC (prescription four) control striped rice borer optium concentration; Experimental scheme 12g/ mu, 14g/ mu, 16g/ mu and 4 concentration gradients of 18g/ mu are also done contrast with the effect of 4% ethyl multiple killing teichomycin SC (12g/ mu), 4% butene-fipronil SC (12g/ mu) respectively; Test method and investigation method are the same, and specifically data (mean values of three repetitions) are as follows:
The effect table of table 4 4% ethyl multiple killing teichomycin butene-fipronil SC different amounts control striped rice borer
Annotate: data are the mean value that repeats for 3 times in the table, and letter is all Duncan testing differentia remarkable time mutually: in July, 2011 place: the Hubei Xiaogan
Can find out from the result of the above-mentioned test of pesticide effectiveness; Increase along with the prescription dosage; Drug effect also increases to some extent, and 4% ethyl multiple killing teichomycin butene-fipronil SC consumption is a 14g/ mu, and the seedling protecting effect of 25d is 89.97% behind the medicine; Apparently higher than the mu consumption is single agent of 4% ethyl multiple killing teichomycin SC and the single agent of 4% butene-fipronil SC of 12g, and difference is extremely remarkable; When the mu consumption was 16g and 18g, 25 days seedling protecting effect is respectively 91.11% and 91.96% after medication, and was not remarkable with the difference of 12g/ mu.Therefore, under the prerequisite of considering the mu cost, should advocate mu usage amount is 12g/ mu.
