[0587] Bioactivity assay

[0588] Example 5: Determination of fungicidal activity against soybean rust

[0589] Protective activity testing method: A live pot test method was used. The sample of the test compound was dissolved in a small amount of solvent (the type of solvent, such as acetone, methanol, DMF, etc., selected based on its solubility in the sample; the volume ratio of solvent to spray volume was equal to or less than 0.05), diluted with water containing 0.1% Tween 80, to prepare the test solution of the required concentration. A separate aqueous solution of the solvent was used as a blank control. The test solution was sprayed onto the diseased host plants (standard potted seedlings cultivated in a greenhouse) using a crop sprayer. Disease inoculation was performed 24 hours later. Based on the characteristics of the disease, diseased plants requiring temperature and humidity control were inoculated and placed in an artificial climate chamber for cultivation. After the disease had fully infected the plants, they were transferred to a greenhouse for further cultivation. Diseased plants not requiring humidity control were directly inoculated and cultivated in the greenhouse. The disease control effect of the compound was evaluated after the control group had fully developed the disease (usually one week).

[0590] The in vivo protective activity against soybean rust is as follows:
