The temperature is low and the onion fields look at the control of Mai Niang.

In order to control the green onion fields, you can use quizalofop-p-ethyl, high-efficiency flupirtine, and clethodim. The herbicidal effects of quizalofop-p-ethyl and flupirrazdipine are highly influenced by temperature. Among them, quizalofop-methyl has a poor herbicidal effect at temperatures below 10°C and does not even have an effect. High-efficiency flupirazione is relatively low-temperature-resistant, but at temperatures below 5°C, the efficacy is also significantly reduced. The clethodim is more resistant to low temperatures and is applied at a temperature higher than 2°C. It also has good effects on weeds such as Aegilops.
