| Abstract: | According to the pesticide guidelines for laboratory bioactivity test and field trials of herbicides control effect, activities of 14 herbicides to wild broomcorn millet were investigated in greenhouse, and control efficacy was evaluated in field. The results showed that herbicides by soil treatment, including isoxaflutole, flufenacet, acetochlor, S metolachlor, and clomazone, were more effective to wild broomcorn millet, with the ED90 values of 43.08, 47.14, 137.09, 209.93 and 583.74 g/hm2 (active ingredient dose), respectively. Topramezone, haloxyfop-P-methyl, nicosulfuron, and fenpyrazone by stem leaf spraying were also efficient, with the ED90 values of 22.21, 35.95, 95.64 and 111.43 g/hm2, respectively. Field efficacy tests showed that before wild broomcorn millet seedling, flufenacet 40% SC (810 g/hm2), acetochlor 900 g/L EC (1 620 g/hm2) and S metolachlor 960 g/L EC (2 160 g/hm2) were effective, the plant control efficacy were all above 86.0% and the fresh weight control efficacy were above 88.4% after 40 days. The control efficacy of isoxazolone 75% WG (90 g/hm2) ranged from 82.5% to 84.8%, clomazone 480 g/L EC (1 008 g/hm2) ranged from 76.3% to 81. 6%, while atrazine 38% SC (1 710 g/hm2) had no effect. In the stem leaf treatment, the control efficacy of haloxyfop-P-methyl 108 g/L EC (72. 9 g/hm2) was the highest, which ranged from 94.8% to 96.5% after 30 days. The control efficacy of fenpyrazone 9% OD (120 g/hm2), topramezone 30% SC (27 g/hm2) and nicosulfuron 40 g/L OD (60 g/hm2) were 72.2%-84.5% after applied 30 days. Mesotrione·nicosulfuron·atrazine 28% OD (630 g/hm2) was effective against wild broomcorn millet. In the fields where wild broomcorn millet occurred seriously, pre emergence herbicides including amide herbicides such as flufenacet, acetochlor, S metolachlor, and post emergence herbicides including haloxyfop-P-methyl and mixed herbicides such as mesotrione·nicosulfuron·atrazine, could be used to control wild broomcorn millet. In the fields where wild broomcorn millet occurred slightly, the pre emergence herbicides isoxazolone and clomazone, the post emergence herbicides topramezone, fenpyrazone and nicosulfuron, could be used. The herbicides used in different crop fields should be selected according to the registration scope of chemicals. |
