Screening and Safety Evaluation of Herbicides in Oat Field

In order to screen safe and efficient herbicide varieties and combinations suitable for oat field use, field plot experiment method was used to spray stems and leaves from 3 to 5 leaf stages of oat. The results showed that the control effects of single-dose treatment of 45.9% difluoro-dioctyl SC 450 mL/hm² and 20% tribenuron-chlorofluoropyroxyacetic acid WP 900 g/hm² on weeds in oat fields were all above 80%, herbicides 10% tribenuron-methyl WP 150 g/hm², 42% 2-methyl·fluroxypyr EC 1125 mL/hm², 48% bentazone AS 3000 mL/hm² and 72% 2,4-D butylate EC 150 mL/hm² mixed use, and 10% pyrazone WP 300 g/hm² 56% 2-methyl 4-sodium chloride WP 1200 g/hm² 50 g/L difluorsulphonamide SC 90 mL/hm² mixed use of broad-leaved weeds in oat field control effect were more than 80%, significantly higher than the conventional herbicide used in production, 48% bentazone AS 3000 mL/hm² 72% 2,4-D butylate EC 150 mL/hm² and 2-methyl·fluroxypyr EC 1125 mL/hm² 72%. The test results enriched the available herbicide varieties for chemical weeding in oat fields and could be applied in oat fields.
