What pesticide can be used to kill acacia, and it is best to use it once ~ ~ ~

That must be acacia, also called Robinia pseudoacacia. Is it the one in the photo? The use of herbicide metsulfuron-methyl, chlorsulfuron-methyl or bensulfuron-methyl in wheat field or rice field is too simple, cheap and convenient to use, and it can be used by root irrigation and foliar spraying, and the dosage is not much. It is enough to use metsulfuron-methyl or chlorsulfuron-methyl for 10 grams and 20 grams of a tree, and 30 to 50 grams of tribenuron-methyl at most.
