Analyze above-mentioned data result and show, when multiple killing teichomycin and spiral shell mite ester different proportion were composite, the co-toxicity coefficient of prescription was all greater than 100, wherein filled a prescription one, the co-toxicity coefficient of prescription two, prescription three is greater than 120, has obvious synergistic effect.The synergistic effect of prescription two, prescription three is the most obvious, and its co-toxicity coefficient is for being respectively 151.25 and 161.14.
By the indoor biometrics test, select the field trial that the larger prescription of CTC two, prescription three and the less prescription five of CTC are prevented and treated two spotted spider mite, determine the effect of different formulations control two spotted spider mite; Simultaneously by with the Contrast on effect of multiple killing teichomycin, spiral shell mite ester single dose, verify the synergistic effect after composite.Concrete test method and data are as follows:
Test the test of pesticide effectiveness that one: 8% multiple killing teichomycin spiral shell mite ester SC, 10% multiple killing teichomycin spiral shell mite ester WP, 20% multiple killing teichomycin spiral shell mite ester WDG do the field control two spotted spider mite, use simultaneously 5% multiple killing teichomycin and 15% spiral shell mite ester in contrast.Test site is Anyuan County, Ganzhou Prefecture, Jiangxi Province, and the time is on April 19th, 2011, test totally four processing, and each processes three repetitions, residential quarter randomized arrangement, residential quarter area 80m
2, the planting habit of all residential quarters all planting habit with local is identical, and the record dispenser same day and the synoptic data in a week thereafter are specific as follows:
Table 9 duration of test meteorological data
The investigation standard is: 7d gets killed strain 50 strains at random behind the medicine in each residential quarter, and the life or death number of bat dish method metering nymph calculates lethality; 15d, 25d adopt every residential quarter 150 clumps of parallel sampling method samplings behind the medicine, investigate withered calculation, calculate at last withered heart rate and seedling protecting effect.Concrete data (data are the mean value of three repetitions) are as follows:
The effect table of table 10 8% multiple killing teichomycin spiral shell mite ester SC and other chemical control two spotted spider mite
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 April, 2011 place: the Ganzhou
As can be seen from the above data, in the situation of identical using dosage, 25d behind medicine, the control rate of 8% multiple killing teichomycin spiral shell mite ester SC, 10% multiple killing teichomycin spiral shell mite ester WP reaches respectively 84.45% and 87.55%, effect when being higher than the use of 15% spiral shell mite ester and 5% pleocidin single dose far away, difference is extremely remarkable.Simultaneously, 20% multiple killing teichomycin spiral shell mite ester 25d after medication, its control efficiency to two spotted spider mite on the oranges and tangerines has reached 67.72%, and the preventive effect when only using a kind of single dose is significantly improved.Simultaneously, above-mentioned field trial also with the data of indoor biometrics test match (CTC is larger, and synergistic effect is larger).
Can find out that the control efficiency of prescription two and prescription three is best, but the two difference is not remarkable, as considering again the environment friendly of pesticidal preparations.Because the dust of pulvis is more, and suspending agent is the novel formulation that recent years, country promoted, and it has more added water base phase constituent, thus more friendly to environment, so think that prescription two is even more ideal.
8% multiple killing teichomycin spiral shell mite ester SC (prescription two) is carried out further test, filtered out the optium concentration of control two spotted spider mite.Experimental scheme 4g/ mu, 5g/ mu, 6g/ mu and 4 concentration gradients of 7g/ mu are also done contrast with the effect of 15% spiral shell mite ester (5g/ mu), 5% multiple killing teichomycin (5g/ mu), test method and investigation method are the same, and concrete data (mean values of three repetitions) are as follows:
Table 11 prescription two different amounts control two spotted spider mite effect table
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 April, 2011 place: the Ganzhou
Can find out that from the result of the above-mentioned test of pesticide effectiveness along with the increase of prescription dosage, drug effect also increases to some extent, 8% multiple killing teichomycin spiral shell mite ester SC consumption is 5g/ mu, the seedling protecting effect of 25d is 90.17% behind the medicine, and apparently higher than 5% multiple killing teichomycin and 15% spiral shell mite ester, difference is extremely remarkable; When the mu consumption was 6g and 7g, 25 days seedling protecting effect is respectively 91.50% and 91.98% after medication, and was not remarkable with the difference of 5g/ mu.Therefore, under the prerequisite of considering the mu cost, should advocate mu usage amount is 5g/ mu.
