[0028] Biological Assay Example 1: Indoor Toxicity Assay Test.
[0029] Drugs to be tested: 96% quinclorac original drug, 95% clopyrazosulfuron-methyl original drug and 95% atrazine original drug.
[0030] Targets for testing: Chenopodium glaucum, Echinochloa crusgalli, Cyperus rotundus.
[0031] Drug configuration design: single dose of quinclorac was prepared as 4, 8, 12g a.i. / ha solution for standby; Prepare 6, 12, 18g a.i. / ha solutions for use; quinclorac, clopyrazosulfuron-methyl and atrazine mixtures are prepared as 4+0.3+6, 4+0.3+12, 4+0.3+18, 4+ 0.6+6, 4+0.6+12, 4+0.6+18, 4+0.9+6, 4+0.9+12, 4+0.9+18, 8+0.3+6, 8+0.3+12, 8+0.3+ 18, 8+0.6+6, 8+0.6+12, 8+0.6+18, 8+0.9+6, 8+0.9+12, 8+0.9+18, 12+0.3+6, 12+0.3+12, 12+0.3+18, 12+0.6+6, 12+0.6+12, 12+0.6+18, 12+0.9+6, 12+0.9+12, 12+0.9+18g.a.i. / ha solution for use.
[0032] Test method: Put a certain amount of soil in a plastic pot with a height of 6 cm and a diameter of 9 cm, sow 15 to 20 seeds of the target weed in the pl...
Embodiment 2
[0049] Biological Assay Example 2: Efficacy Test for Controlling Annual Weeds in Sorghum Field.
[0050] The experiment was carried out in Longxing Village, Yile Town, Jiang'an County, Yibin County, Sichuan Province. There were 8 treatments in the test, and 3 repetitions were set up for each treatment. The treatment 1 was 25% quinclorac · clopyrazosulfuron · atrazine dispersible oil suspension concentrate (8:2:15), and the treatment 2 was 25% % quinclorac wettable powder, treatment 3 is 75% clopyrazosulfuron water dispersible granules, treatment 4 is 38% atrazine suspension concentrate, treatment 5 is contrast (does not apply pesticides and does not weed), after 30 The number of weeds in each treatment was counted every day and the control effect was calculated.
