Abstract
This study was conducted to evaluate the efficacy and phytotoxic of crop desiccant treatments on the seed production of Italian ryegrass (Lolium multiflorum Lam.) in Gimje and Buan, South Korea. Here, Italian ryegrass was treated 7, 10, and 14 days before harvest (DBH) and no difference in fresh weight, 1000-seed weight, germination rate, and seed yield was observed compared to the untreated control in the standard dose and double dose for seven DBH. However, the standard dose and double dose on the 10 DBH and 14 DBH had a lower 1000-seed weight, germination rate, and seed yield compared to the untreated control. In pesticide persistence analysis, the permitted standards were not exceeded in the seeds and straw according to the treatment time and concentration. These results suggest that the treatment effect and stability of Italian ryegrass can be expected if treated within seven DBH. However, it seems that crop desiccants should be used after considering grain ripening and weather to minimize loss of seeds.
