Description
Technical field
The present invention relates to the agriculture chemical compounding technical field, particularly relate to a kind of miticide composition that contains fluacrypyrim and Bifenazate.
Background technology
Fluacrypyrim is first methoxy acrylic miticide that BASF AG develops the exploitation of Japanese Cao Da company.Have and well tag and stomach poison function, to each characteristics of evil mite, if comprise the ovum mite, become mite all effective, and quick-acting is good, and the lasting period is long, is mainly used in preventing and treating the multiple harmful mite of fruit tree, as preventing and treating the two spotted spider mite of mandarin tree, apple tree.The chemistry of fluacrypyrim is called methyl (E)-2-{ α-[2-isopropoxy-6-(trifluoromethyl) pyrimidine-4-phenoxy group]-0-tolyl }-the 3-methoxy acrylate
,Its chemical structural formula is
Bifenazate is a kind of new selective foliar spray miticide.Its mechanism of action is the unique effect to an aminobutyric acid (GABA) acceptor of the nervous centralis conducting system of mite class.Its each life stage to mite is effective, has ovicidal activity and knocks down activity (48～72h), and the lasting period is long to what become mite.About lasting period 14d, the recommendation dosage range is interior to crop safety.To parasitic wasp, Predatory Mites, Chrysopa low-risk.Be used for the control of apple and grape European red mite, Tetranychus urticae and McDaniel mite, and the Tetranychus urticae of ornamental plants and Lewis mite.The chemical name of Bifenazate: 3-(4-methoxyl biphenyl base-3-yl) carbazic acid isopropyl ester.
In the real process of agricultural production, use chemical agent and be the most effectively means of control plant pest, but by the chemical control insect the problem of easy generation be the generation of pest resistance to insecticide.And long-term use single chemical insecticide continuously high dose, cause easily the series of problems such as residual, environmental pollution of medicament.Reasonably chemical insecticide is composite or be mixed and have the expansion insecticidal spectrum, improve control efficiency, prolong the optimum period for applying fertilizer, reduce dosage, reduce poisoning, reduce residual, delay pest resistance and the positive characteristics such as drug-fast generation and development, miticide is composite or to be mixed be the most one of the effective method that addresses the above problem.We filter out fluacrypyrim and Bifenazate is composite on the basis of lab screening and field trial, have obvious synergistic effect.And about the composite miticide composition of fluacrypyrim and Bifenazate and use and there is no at present the people and reported.
Summary of the invention
Based on above situation, the object of the invention is to provide a kind of new and effective agricultural chemicals miticide composition.Be mainly used in preventing and treating apple, oranges and tangerines, grape two spotted spider mite, apple Tetranychus urticae and McDaniel mite, and the Tetranychus urticae of ornamental plants and Lewis mite.

Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, the present invention describes with following specific embodiment, but the present invention only limits to absolutely not these examples.The method that the present invention adopts indoor bioassay and field trial to combine.If no special instructions, the ratio of below mentioning (comprising percentage) all is ratio of quality and the number of copies.
Embodiment: the different proportioning co-toxicity experiments from Bifenazate of fluacrypyrim.
1.1 reagent agent
The former medicine of 98% fluacrypyrim, the former medicine of 96% Bifenazate, above-mentioned former medicine provides by research and development department of Qingdao Hailir Pesticides and Chemical Co., Ltd..
1.2 test target
The examination mite is picked up from the Citrus Research Institute Of Chinese Academy Of Agricultural Sciences test site, and the cultivation management term harmonization is not used medicament in the recent period, adopts the blade that rewinds citrus red mite (crm), and is for subsequent use after normal temperature laboratory (about 25 ℃) raised for 2 generations with fresh citrus leaves down.
1.3 single dose assay method slide infusion process
If choose the female mite that Individual Size is consistent, body colour is scarlet, to try the mite back side with writing brush sticks on the slide that posts cloth insertion sheet, every slide dilution intervals, on the basis of prerun, respectively two kinds of former medicines are dissolved in acetone, be diluted to 5 concentration gradient liquids with the 0.1% Tween 80 aqueous solution again, place beaker for subsequent use.5 concentration gradients are respectively 6:30; 9:27; 12:24; 15:21; 18:18.
The glutinous slide that the examination mite arranged is immersed in the good liquid 5 seconds, each processes four repetitions, after taking-up tiltedly is put in porcelain dish edge drying, be put in the Glass carrier box, do not add a cover the illumination box of putting into (25 ± 1) ℃, humidity 7O%～80%, illumination every day 10 hours, microscopy life or death mite number (with its foot of fine, soft fur style of writing, the nonresponder is dead) after 24 hours.
1.4 data statistics and analysis
According to investigation statistics, calculate the corrected mortality that each is processed.And adopt the abundant method of Sun Yun to calculate the co-toxicity coefficient (CTC value) of mixture with reference to NY/T1 154.7-2006.If contrast lethality＜5% is not proofreaied and correct, the contrast lethality by formula 2 is proofreaied and correct between 5%-20%, the contrast lethality〉20%, test need be reformed.
Take the logarithm value of drug concentration (mg/L) as independent variable x, take the probability value of corrected mortality as dependent variable y, set up respectively the virulence regression equation formula, adopt DPS software to calculate the LC of single dose and each proportioning mixture
50Calculate co-toxicity coefficient (CTC) according to the abundant method of Sun Yun.Co-toxicity coefficient CTC, computing formula is as follows: (take fluacrypyrim as the standard medicament, its toxicity index is 100):
The LC of the toxicity index of Bifenazate (TI)=fluacrypyrim
50The LC of/Bifenazate
50* 100
The LC of the true toxicity index (ATI) of M=fluacrypyrim
50The LC of/M
50* 100
The TI of the TI of the theoretical toxicity index (TTI) of M=fluacrypyrim * P fluacrypyrim+Bifenazate * P Bifenazate
The TTI of the ATI/M of the co-toxicity coefficient of M (CTC)=M * 100
In the formula:
M is fluacrypyrim and the mixture of the different proportionings of Bifenazate
The P Bifenazate is Bifenazate shared ratio in mixture
The P fluacrypyrim is fluacrypyrim shared ratio in mixture.
2.1 toxicity test result
Table 1 fluacrypyrim, Bifenazate are to the indoor measurement result of citrus red mite (crm)
As can be seen from the table, in different proportionings, its co-toxicity coefficient shows certain synergistic effect, wherein fluacrypyrim all greater than 120: Bifenazate is that the synergistic effect of 12:24 is the most obvious, and co-toxicity coefficient is 178.93.Result of the test shows, the Compositional acaricide of fluacrypyrim and Bifenazate all has higher activity to citrus red mite (crm) under indoor conditions, suggestion is carried out further field control effectiveness test to suitable proportion 12:24 left and right sides mixture preparation, to estimate its field practical application effect.
