A kind of bactericidal composition containing tiger glue adipic acid copper
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition containing tiger glue adipic acid copperApplication on corps diseases.
Background technology
Tiger glue adipic acid copper (copper (succinate+glutarate+adipate)), copper ion and cause of diseaseThe lip-deep cation exchange of mycoderm, makes the protein coagulating on pathogen cell membrane, simultaneouslyPart copper iontophoretic injection enters in pathogen cell and is combined with some enzyme, affects its activity. AvailableIn control cucumber bacterial angular leaf spot, and plant growth is had to spread effect.
Fluoxastrobin, Fluoxastrobin all belong to methoxy acrylic bactericide, are widely used inIn the disease of crops.
But, in the real process of agricultural production, prevent and treat the problem that disease the most easily producesIt is the generation of disease drug resistance. Different cultivars composition carries out composite, is to prevent and treat resistance disease veryCommon method. Heterogeneity is carried out composite, according to practical application effect, judges certainComposite be synergy, add and or antagonism. In most cases, the composite effect of sterilizationFruit is all additive effect, really has the composite little of synergistic effect, and especially synergistic effect is non-Chang Mingxian, synergy ratio very high composite just still less. Through inventor's research, finding willAfter tiger glue adipic acid copper and fluoxastrobin, azoxystrobin compound, can produce good synergistic effect, andRelevant report about tiger glue adipic acid copper and fluoxastrobin, azoxystrobin compound is not yet open.

The embodiment of the present invention is the method that adopts Toxicity Determination and field test to combine. FirstBy Toxicity Determination, the synergy ratio after clear and definite two kinds of medicaments are composite by a certain percentage(SR), SR < 0.5 is antagonism, and 0.5≤SR≤1.5 are summation action, and SR > 1.5 isSynergistic effect, on this basis, then carries out field test.
Test method: after the effective inhibition concentration scope of each medicament is determined in prerun, medicament is by effectiveComponent content is established respectively 5 dosage processing, establishes clear water contrast. With reference to " the indoor biometric of agricultural chemicalsDetermine test rule bactericide " carry out, adopt mycelial growth rate method to measure medicament to crop germVirulence. After 72h, measure colony diameter by right-angled intersection method, calculate each processing net growth,Mycelial growth inhibition rate.
Net growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), liquor strength (μ g/mL) conversionBecome logarithm value (x), try to achieve virulence regression equation (y=a+bx) with least square method, and thusCalculate the EC of every kind of medicament50Value. Calculate the different proportionings of two medicaments according to Wadley method simultaneouslySynergy ratio (SR), SR < 0.5 is antagonism, 0.5≤SR≤1.5 are summation action,SR > 1.5 is synergistic effect. Computing formula is as follows:
Wherein: a, b are respectively active components A and active component B shared ratio in combination;
A is tiger glue adipic acid copper;
B is selected from the one in fluoxastrobin, Fluoxastrobin.
Application Example two:
For trying disease: rice green smut
Test medicine provides by Shaanxi Meibang Pesticide Co., Ltd..
Experimental design: determine tiger glue adipic acid copper and the former medicine of fluoxastrobin and the two through pilot studyEffective inhibition concentration scope of different proportioning mixtures.
Toxicity test result
The composite toxicity test analysis of results table to rice green smut of table 9 tiger glue adipic acid copper and fluoxastrobin
As shown in Table 9, tiger glue adipic acid copper and fluoxastrobin proportioning in the time of 1 ︰ 80~80 ︰ 1 to waterThe synergy ratio SR of rice false smut is all greater than 1.5, illustrates that both are in 1 ︰ 80~80 ︰ 1 scopesInterior mixture all shows synergistic effect, when the proportioning of tiger glue adipic acid copper and fluoxastrobin is at 1 ︰When 10~30 ︰ 1, synergistic effect is more outstanding, and synergy ratio is all more than 2.30. Through ShenAsk someone to test and find that the optimum ratio of tiger glue adipic acid copper and fluoxastrobin is 30:1,25:1,20:1、15:1、10:1、9:1、8:1、7:1、6:1、5:1、4:1、3:1、2:1、1:1、1:2、1:3、1:4、1:5、1:6、1:7、1:8、1:9、1:10, especially synergy ratio maximum in the time that tiger glue adipic acid copper and fluoxastrobin weight ratio are 3:1,Synergistic effect is the most obvious.
Application Example three
For trying disease: pepper anthracnose
Test medicine provides by Shaanxi Meibang Pesticide Co., Ltd..
Experimental design: determine tiger glue adipic acid copper and the former medicine of Fluoxastrobin and the two not through pilot studyWith effective inhibition concentration scope of proportioning mixture.
Table 10 tiger glue adipic acid copper and the azoxystrobin compound toxicity test analysis of results table to pepper anthracnose
As shown in Table 10, tiger glue adipic acid copper and Fluoxastrobin proportioning in the time of 1 ︰ 80~80 ︰ 1 to pepperyThe synergy ratio SR of green pepper anthracnose is all greater than 1.5, illustrates that both are in 1 ︰ 80~80 ︰ 1 scopesInterior mixture all shows synergistic effect, when the proportioning of tiger glue adipic acid copper and Fluoxastrobin is at 1 ︰When 10~20 ︰ 1, synergistic effect is more outstanding, and synergy ratio is all more than 2.25. Through ShenAsk someone to test and find that the optimum ratio of tiger glue adipic acid copper and Fluoxastrobin is 20:1,15:1,12:1、10:1、5:1、4:1、3:1、2:1、1:1、1:2、1:3、1:4、1:5,1:6,1:7,1:8,1:9,1:10, especially when tiger glue adipic acid copper and FluoxastrobinSynergy ratio maximum when weight ratio is 2:1, synergistic effect is the most obvious.
Find through test: routed in various crop after tiger glue adipic acid copper and active component B are compositeUlcer disease, shot hole, scab, white rot, anthrachose of grape, bacterial angular leaf spot, leaf blight,Anthracnose, false smut, damping-off, gray mold, sclerotiniose, rust, epidemic disease, leaf spot,The control of glume blight, moire disease, brown spot, net blotch, smut, downy mildew or powdery mildewHave obvious synergistic effect, synergy ratio SR is all greater than 1.5.
