Performance test

Detection method/test method

The performance of the pesticides prepared in the examples and the comparative examples of the application is detected according to GB/T17980.30-2000 'pesticide field efficacy test criterion (I) bactericide for controlling cucumber powdery mildew', and the control effect of the pesticides in the examples 1-27 and the comparative examples 1-8 on cucumber powdery mildew is calculated and recorded.

Table 2 performance testing data

As can be seen from table 2, the control effect of the marine plant-derived pesticide of the present application is excellent, and the control effect is the best in example 3, which is the most preferable example, as seen from the test results of examples 1 to 5 and comparative example 8.

By combining the test results of the example 3 and the example 13 and the comparative examples 1 and 5, the finished pesticide prepared by compounding the kelp extract prepared by enzymolysis of the kelp by the protease with other active ingredients has excellent control effect.

By combining the test results of example 3, examples 22 to 27 and comparative examples 1 to 4, it can be seen that the seaweed plant extract, the derris extract, the difenoconazole and the metiram have a compounding relationship, that is, complementary effects exist in the control effect, and the control effect is improved.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
