Seeds of broadleaf weeds (zinnia and piemarker) or grassy weeds (green bristlegrass and barnyard grass) were respectively sown in a paper cup having a diameter of 7 cm and containing nutrient soil; after sowing, the seeds were covered with 1 cm of soil, the soil was pressed and watered, and then the seeds were cultivated in a greenhouse according to a conventional method; and stems and leaves were sprayed after 2-3 leaf stage of the weeds.
After the original medicinal acetone was dissolved, the test requires to use 1‰ of Tween 80 to stand in running water to prepare the solution to be tested with a required concentration. According to the design dose of the test, spray treatment was carried out on a track-type crop sprayer (designed and produced by British Engineer Research Ltd.) (spray pressure is 1.95 kg/cm2, spray volume is 500 L/hm2 and track speed is 1.48 km/h). The test was repeated for three times. The test material was treated and then placed in an operation hall. The medicinal liquid was naturally dried in the shade, and then was placed in a greenhouse and managed according to the conventional method. The response of the weeds to the drug was observed and recorded. After treatment, the control effects of the test drug on the weeds were visually inspected regularly, expressed by 0-100%. “0” represents no control effect and “100%4” represents complete killing.
The test results show that the compounds of the formula I generally have high control effects on various weeds. Part of the test compounds, such as compounds 1-1, 1-7, 1-18, 1-20, 1-42, 1-76, 1-81, 1-82, 1-226, 1-259, 1-262, 1-265, 1-280, 1-292, 1-346, 1-349, 1-367, 1-370, 1-371, 2-1, 2-19, 2-37, 2-55, 2-67, 2-73, 2-121, 2-123, 2-289, 2-291, 2-307, 2-309, 2-379, 2-380, 2-383, 2-386, 2-391, 2416, 2417, 2-418, 2-419 and 2420, have good control effects on zinnia, piemarker, green bristlegrass or barnyard grass at the application dose of 600 g a.i./hm2, and the control effects are greater than or equal to 90%.
According to the above test method, part of the compounds of the formula I and KC1 are selected for activity test of controlling the zinnia. The results are shown in Table 5.
According to the above test method, part of the compounds of the formula and KC1 are selected for activity test of controlling the piemarker. The results are shown in Table 6.
According to the above test method, part of the compounds of the formula I and KC1 or KC2 are selected for activity test of controlling the green bristlegrass. The results are shown in Table 7.
According to the above test method, part of the compounds of the formula I and KC1 or KC2 are selected for activity test of controlling the barnyard grass. The results are shown in Table 8.
To sum up, the alkene-containing carboxylic ester compound of the present invention has excellent herbicidal activity, also has high herbicidal activity at a lower dosage, and can be used for agriculturally controlling various weeds.
