A kind of bactericidal composition that presses down mould azoles and own azoles alcohol that contains
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of bactericidal composition on crop pest that presses down mould azoles and own azoles alcohol that contain.
Technical background
Pressing down mould azoles (imazalil) is triazole bactericidal agent.Molecular formula is C

Practice example two: it is composite to the powdery mildew of cucumber Toxicity Determination to press down mould azoles and own azoles alcohol
Test medicine provides by Shaanxi means of agricultural production trade Co., Ltd of U.S. nation.
After the effective inhibition concentration scope of each medicament was confirmed in prerun, each medicament was established 5 dosage respectively by active constituent content and is handled, and established the clear water contrast.Carry out with reference to " agricultural chemicals indoor bioassay test rule bactericide ", adopt the mycelial growth rate method to measure the virulence of medicament powdery mildew of cucumber.Measure colony diameter with the right-angled intersection method behind the 72h, calculate and respectively handle clean amount of growth, mycelial growth inhibition rate.
Clean amount of growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (mg/L) converts logarithm value (x) to, tries to achieve virulence regression equation (y=a+bx) with method of least squares, and calculates the EC of every kind of medicament thus
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR＜0.5 is an antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect.Computing formula is following:
Wherein: a, b are respectively and press down mould azoles and own azoles alcohol shared ratio in combination
A is for pressing down mould azoles
B is own azoles alcohol
Result of the test is as shown in table 1:
Table 1 presses down mould azoles, own azoles alcohol and composite toxicity test analysis of results table to powdery mildew of cucumber thereof
Can know by table 1, press down mould azoles, own azoles alcohol EC powdery mildew of cucumber
50Be respectively 28.53mg/L and 0.56mg/L.The virulence that presses down mould azoles is lower than the virulence of own azoles alcohol.Press down 9: 1,6: 1,3: 1,1: 1,1: 3 synergy ratio of mould azoles and own azoles alcohol proportioning and be respectively 1.57,2.09,2.73,2.11,1.54; Explain press down mould azoles and own azoles pure both be mixed in the scope at 9: 1 to 1: 3 and all show obvious synergistic effect; Synergy ratio SR maximum when pressing down mould azoles and be 3: 1 with own azoles alcohol weight ratio wherein, synergistic effect is the most obvious.

This EE is the Hanzhong City suburb in Shaanxi Province, and test medicine is researched and developed, provided by Shaanxi means of agricultural production trade Co., Ltd of U.S. nation, and contrast medicament 22.2% presses down mould azoles missible oil (commercial), 10% own azoles alcohol missible oil (commercial).
The preceding investigation of medicine rice sheath blight disease disease index, in the their early stage dispenser, dispenser for the second time after 10 days, dispenser is 2 times altogether, investigates disease indexs in 7 days, 15 days after the dispenser for the second time and calculates preventive effect.Experimental result is as follows:
Table 5 presses down mould azoles, own azoles alcohol and the composite rice sheath blight disease test of pesticide effectiveness of preventing and treating thereof
| Handle medicament | The preparation dosage | 7 days preventive effects (%) behind the medicine for the second time | 15 days preventive effects (%) behind the medicine for the second time |
| 15% presses down the own azoles alcohol of mould azoles wetting powder | 30 gram/mus | ?89.74 | 94.05 |
| 80% presses down mould azoles diniconazole water dispersible granule | 6 gram/mus | ?88.57 | 93.32 |
| 22% presses down mould azoles hexaconazole suspending agent | 28 gram/mus | ?90.20 | 94.74 |
| 16% presses down mould azoles hexaconazole aqueous emulsion | 30 gram/mus | ?89.74 | 94.23 |
| 10% presses down mould azoles hexaconazole microemulsion | 40 gram/mus | ?88.24 | 93.83 |
| 22.2% presses down mould azoles missible oil | 30 gram/mus | ?72.58 | 78.51 |
| 10% own azoles alcohol missible oil | 18 gram/mus | ?74.39 | 82.34 |
Can be found out that by table 5 press down mould azoles and can effectively prevent and treat rice sheath blight disease with own azoles after pure composite, control efficiency all is superior to contrasting medicament, the lasting period is long.In the test scope of medication, the target crop is had no adverse effects, and rice green smut is had preventive effect preferably, preventive effect reaches more than 90%.
