Preparation requirement according to above suspending agent or water dispersible granules; Preparation chlorfenapyr and the several formulations product of cyanogen insect amide under 1: 40～50: 1 ratio therefrom select several kinds of representational ratios (1: 40,1: 10,1: 5,1: 1,1.5: 1,2.5: 1,10: 1,20: 1,50: 1) to carry out the indoor biometrics experiment.
Diamond-back moth is the primary pest on the brassicaceous vegetable, calls the square moth, hangs corpse worm, little blue or green worm etc.Adult is small-sized moth class; Larva is active, meet when frightened twisting retreat or weave silk sagging, mature larva body yellow green, a taupe, the polypide middle part is thick, two ends are tiny of the shuttle shape.Each big vegetable-growing area takes place throughout the year, takes place particularly serious in 3～June, 9～December.Adult is many to lay eggs on bud, tender leaf and spray.After the larva hatching just leaf mining get food mesophyll, stay epidermis, on the dish leaf, form transparent one by one spot, full leaf is eaten and is reticulated when serious; Just be hidden in blade back harm after 2 ages, cause the dish leaf to incise; Larva also can endanger tender stem, young pod and seed on the dish of reserving seed for planting, influence solid.In recent years, agricultural chemicals uses in a large number, and the pesticide resistance of diamond-back moth sharply strengthens, and causes increasing agricultural chemicals that diamond-back moth was lost efficacy.
The method of indoor biometrics is: adopt capillary trace drop method, capillary trace dropper volume is 1.0 μ L.With micro-dropper with soup by a drop in the back side of rice fulgorid larva, 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, be addition during 80-120.
The different proportionings of table 1 are to the toxicity test result of diamond-back moth
Analyze above-mentioned data result and show, when chlorfenapyr and cyanogen insect amide different proportion are composite, each proportioning co-toxicity coefficient all greater than 120, have obvious synergistic effect.Wherein the synergistic effect of proportioning 5 and proportioning 6 is the most obvious, and its co-toxicity coefficient is respectively 159.96 and 158.34.
Through the indoor biometrics test, select the field trial that the less proportioning 2 of the bigger proportioning of CTC 5, proportioning 6 and CTC is prevented and treated diamond-back moth, wherein proportioning 5, proportioning 6, proportioning 2 are added according to following active ingredient respectively:
Prescription one (proportioning 5): 25% suspending agent
Chlorfenapyr 15%
Cyanogen insect amide 10%
Prescription two (proportionings 6): 35% water dispersible granules
Chlorfenapyr 25%
Cyanogen insect amide 10%
Prescription three (proportionings 2): 5.5% suspending agent
Chlorfenapyr 0.5%
Cyanogen insect amide 5%
According to the content of effective of being added in above-mentioned each prescription, the compound method according to prescription is mixed with appropriate formulation.Through field control effectiveness test, confirm the effect of above-mentioned three kinds of prescription control diamond-back moths; Simultaneously through with the field efficacy effect comparison of chlorfenapyr, the agent of cyanogen insect amide list, verify the synergistic effect after composite.Concrete test method and data are following:
Test the test of pesticide effectiveness that one: 25% chlorfenapyr cyanogen insect amide SC, 35% chlorfenapyr cyanogen insect amide WDG, 5.5% chlorfenapyr cyanogen insect amide SC do the field control diamond-back moth, use agent of chlorfenapyr list and the agent of cyanogen insect amide list simultaneously as contrast.City east Ma Fangzhen is answered for the Xiaogan Prefecture, Hubei Province in the test place, and the time is on July 22nd, 2010, test totally four processing, and each handles three repetitions, sub-district randomized arrangement, sub-district area 100m
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:
The effect table of table 3 25% chlorfenapyr cyanogen insect amide SC and other chemical control diamond-back moths
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: Yingcheng City, Hubei
The effect table of table 4 35% chlorfenapyr cyanogen insect amide WDG and other chemical control diamond-back moths
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: Yingcheng City, Hubei
The effect table of table 5 5.5% chlorfenapyr cyanogen insect amide SC and other chemical control diamond-back moths
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: Yingcheng City, Hubei
Can find out from above data; Under the situation of identical using dosage; 25d behind medicine; The control rate of 25% chlorfenapyr cyanogen insect amide SC and 35% chlorfenapyr cyanogen insect amide WDG reaches 91.1% and 88.9% respectively, the effect when being higher than agent of chlorfenapyr list and the agent of cyanogen insect amide list use far away, and difference is extremely remarkable.Simultaneously, 5.5% chlorfenapyr cyanogen insect amide SC 25d after medication, its control efficiency to rice fulgorid on the vegetables has also reached 70.8%, and the preventive effect when only using a kind of single agent is significantly improved.Simultaneously, above-mentioned field trial also match (CTC is big more, and synergistic effect is big more) with the indoor biometrics test for data.
This shows that prescription one is best with the control efficiency of prescription two, wherein, the seedling protecting effect of prescription one is a little more than prescription two, so think that prescription one is best.
25% chlorfenapyr cyanogen insect amide SC (prescription one) is carried out further test, filtered out the optium concentration of control diamond-back moth.Experimental scheme 8g/ mu, 10g/ mu, 12g/ mu and 4 concentration gradients of 14g/ mu are also done contrast with the effect of 15% chlorfenapyr SC (10g/ mu), 10% cyanogen insect amide SC (10g/ mu); Test method and investigation method are the same, and specifically data (mean values of three repetitions) are as follows:
Table 6 prescription one different amounts control diamond-back moth 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: Yingcheng City, Hubei
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.25% chlorfenapyr cyanogen insect amide SC consumption is a 8g/ mu, and the seedling protecting effect of 25d is 88.7% behind the medicine, and apparently higher than 10% cyanogen insect amide SC and 15% chlorfenapyr SC, difference is extremely remarkable.When the mu consumption was 10g/ mu, 25 days seedling protecting effect had reached 91.8% after medication, and apparently higher than mu consumption 10g/ mu, difference is extremely remarkable.And after the mu consumption risen to 12g/ mu and 14g/ mu, seedling protecting effect is respectively 92.5% and 93.2%, and was not remarkable with the difference of 10g/ mu.Therefore, under the prerequisite of considering the mu cost, should advocate mu usage amount is 10g/ mu.
