It is bright to analyze above-mentioned tables of data, and when butene-fipronil and Rynaxypyr different proportion were composite, the co-toxicity coefficient of prescription all had obvious synergistic effect all greater than 120.It is 4 maximum with prescription 5 co-toxicity coefficients wherein to fill a prescription, and is respectively 170.95 and 166.89.
Through the indoor biometrics test, select the field trial that the bigger prescription of CTC 4, prescription 5 and the less prescription 1 of CTC are prevented and treated rice-stem borer, confirm the effect of prescription control rice-stem borer; Simultaneously through with the effect comparison of butene-fipronil, the agent of Rynaxypyr list, verify the synergistic effect after composite.Concrete test method and data are following:
Test the field control effectiveness test that one: 15% butene-fipronil Rynaxypyr SC, 10% butene-fipronil SC, 5% Rynaxypyr SC do the 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 11st, 2010; Test totally four processing; Each handles three repetitions; The sub-district randomized arrangement, sub-district area 67m2, the planting habit of all sub-districts all planting habit with local is identical; Record dispenser same day and all synoptic data thereafter, specific as follows:
Table 9 duration of test meteorological data
The investigation standard is: 7d gets killed strain 100 strains at random behind the medicine in each sub-district, and the life or death number of Chilo spp larvae is looked in stripping, 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:
The effect table of table 1015% butene-fipronil Rynaxypyr SC and other chemical 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, 2010 place: the Hubei Xiaogan
Can find out from above data; Under the situation of identical using dosage; 15% butene-fipronil Rynaxypyr SC 25d control rate behind medicine can reach 90.8%, the effect when preventive effect is higher than 10% butene-fipronil SC and 5% Rynaxypyr SC list agent use far away, and difference is extremely remarkable.
Test two: test method, investigation method and meteorological data are the same, and concrete test data is following:
The effect table of table 1120% butene-fipronil Rynaxypyr and other chemical 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, 2010 place: the Hubei Xiaogan
Can find out from above data; Under the situation of identical using dosage; 20% butene-fipronil Rynaxypyr SC 25d control rate behind medicine can reach 91.6%, the effect when preventive effect is higher than 15% butene-fipronil SC and 5% Rynaxypyr SC list agent use far away, and difference is extremely remarkable.
Test three: test method, investigation method and meteorological data are the same, and concrete test data is following:
The effect table of table 125% butene-fipronil Rynaxypyr and other chemical 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, 2010 place: the Hubei Xiaogan
Can find out from above data; Under the situation of identical using dosage; 5% butene-fipronil butene-fipronil 25d control rate behind medicine can reach 80.1%, the effect when preventive effect is higher than 2% butene-fipronil SC and 5% Rynaxypyr SC list agent use far away, and difference is extremely remarkable.
Through above-mentioned three field control effectiveness tests; The effect that can find out prescription 4, prescription 5 control rice-stem borers is best; This also matches with the result of indoor biometrics, and (CTC is big more; Synergistic effect is big more); But the two difference is not remarkable; As considering the factor of pesticide cost again, prescription 4 is best, the most economical proportionings of effect; Also verified simultaneously butene-fipronil and Rynaxypyr by different proportion when composite, the control efficiency of rice-stem borer all has been better than the effect of butene-fipronil and Rynaxypyr list agent use, certain synergistic effect has been arranged.
Through above-mentioned three field control effectiveness tests, can confirm to fill a prescription 4 for preventing and treating the more suitable prescription of rice-stem borer, 15% butene-fipronil Rynaxypyr SC (prescription 4) has been carried out further test, filter out the optium concentration of control striped rice borer.Experimental scheme 6g/ mu, 7g/ mu, 8g/ mu and 4 concentration tonsures of 9g/ mu are also done contrast with the effect of 10% butene-fipronil SC (8g/ mu), 5% Rynaxypyr SC (8g/ mu); Test method and investigation method are the same, and specifically data (mean values of three repetitions) are as follows:
Table 13 prescription 4 different amounts control striped rice borer 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 July, 2010 place: the Hubei Xiaogan
Can find out that from above-mentioned data along with the increase of prescription dosage, drug effect also increases to some extent; 15% butene-fipronil Rynaxypyr SC consumption is a 8g/ mu; The seedling protecting effect of 25d is 91.6% behind the medicine, and apparently higher than 10% butene-fipronil SC and 5% Rynaxypyr SC, difference is extremely remarkable; When consumption was 9g/ mu, 25 days seedling protecting effect and 8g/ mu was roughly the same after medication, and difference is not remarkable.Therefore, under the prerequisite of considering the mu cost, should advocate mu usage amount is 9g/ mu.
