[0033] Indoor Toxicity Determination of Zhongshengmycin and Fludioxonil to R. solanacearum of Watermelon
[0034] Test object: watermelon blight
[0035] Test method: The test adopts the mycelium growth rate method. See Table 1 for the test agent. Take 5ml of the drug solution and add it to an Erlenmeyer flask equipped with 45ml of hot medium (PDA medium, 45-50°C). After shaking well, quickly pour it into a 90mm diameter glass petri dish. Pour 12ml of medium with medicine into it, 4 replicates for each treatment, place it horizontally, and form a flat plate after cooling, and mix an equal amount of sterile water with the medium as a control. Use a puncher with a diameter of 5mm to cut the fungus cake from the edge of the test bacteria that has been cultured for 2 days, and connect the side with mycelium to the poisonous medium with a pick needle. All operations are performed aseptically on the ultra-clean workbench. After treatment, they were placed in a constant temperature...

[0047] Toxicity determination of Zhongshengmycin and fludioxonil compound against tomato damping-off pathogen
[0048] Test object: Tomato damping-off fungus
[0049] Test method and statistical analysis method are the same as biological assay example 1
[0050] It can be seen from Table 2 that when the proportion of Zhongshengmycin and fludioxonil is between 1~10:50~1, the co-toxicity coefficient to watermelon blight is above 120, especially when the proportion is 1~5 : The co-toxicity coefficient between 30 and 1 is above 200, and the synergistic effect is remarkable.
