Do you need to dilute carbendazim when cutting the stem of the God of Wealth for sterilization?

We take 10 ml of carbendazim, dilute it with 300 to 400 times of water, put it in a watering can and shake it evenly, and then spray it on the leaves of the rich tree. When spraying leaves, be sure to spray them on both sides to avoid leaving dead ends. If you can't achieve the effect once, you can spray it several times, usually 2 to 3 times.
