Embodiment 1
[0026] Indoor Toxicity Test of Pyraclostrobin and Bixafen Compound to Banana Scab
[0027] Test object: Banana scab fungus (Macrophomamusae), collected from the field.
[0028] Test method: the test adopts the leaf disc method, weigh a certain amount of pyraclostrobin and bixafen original drug, dissolve in DMF and prepare mother liquor, and dilute with 0.1% Tween-80 surfactant sterilized water , based on the pre-experiment to prepare 7 suitable series of mass concentrations. The two medicinal solutions of pyraclostrobin and bixafen were mixed according to different mass ratios (50:1, 20:1, 10:1, 1:1, 1:10, 1:20, 1:50) Mix to obtain mixed solutions with different proportions, and set the treatment containing only solvent and surfactant but no active ingredient as blank control. Collect fresh banana peel scab disease leaves in the field, rinse the sporangia on the back of the leaves with deionized water, and prepare 1 × 10 8 ~1.5×10 8 sporangia / L suspension for inoculation. ...

[0041] Indoor Toxicity Determination of Pyraclostrobin and Bixafen Compound against Apple Spotted Deciduous
[0042] Test object: Alternaria alternariaf. spmali, collected from the field, and isolated and purified indoors.
[0043] Test method: refer to the "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006", using the mycelium growth rate method. Under aseptic conditions, use a sterilized hole puncher with a diameter of 5mm to punch out the fungus cake along the edge of the mycelia, and use an inoculation needle to inoculate the fungus cake on the center of the plate containing the medicine, with the mycelium facing down , placed in a light incubator at 25°C. Depending on the results of investigation of the control mycelium growth situation, adopt the cross method to measure the colony diameter of each treatment respectively, and calculate the inhibition percentage (%) of different medicaments to mycelium growth according to the following formula, whe...
Embodiment 3
[0052] Weigh 50.0 g of pyraclostrobin technical material, 1.0 g of bixafen technical drug, 5.0 g of calcium lignosulfonate, 1.0 g of sodium lauryl sulfonate, 10.0 g of ammonium sulfate, 2.0 g of corn starch and Diatomaceous earth makes up 100g. After mixing evenly, it is pulverized into a mother powder with a particle size of 0.5 μm to 30 μm by an ultra-fine jet mill, and then the mother powder is added to water and mixed evenly, and then added to a boiling granulator at a boiling temperature of 65°C to 75°C for granulation. After drying and sieving, a 51% pyraclostrobin-bixafen water-dispersible granule was obtained. This example is used to prevent and treat wheat leaf rust. The test was carried out in Nijing Town, Changli County, Hebei Province in May 2015. Wheat leaf rust has occurred seriously in the test site over the years. See Table 3 for details of test agents and doses, each treatment was repeated 4 times, and the area of the plot was 20m 2 , a total of 16 plots, ...
