Biocidal herbicides such as paraquat can be used, making them easy to use. However, it should be noted that it must be sprayed directionally, and do not touch the green parts of the tree, which is easy to be harmed.

Dear users, regarding the problem that herbicides do not harm tamarix, we can provide the following suggestions: First, it is recommended to use oxalate herbicides, which are less harmful to tamarix. The main ingredient of oxalate herbicides is oxalic acid, which can inhibit the photosynthesis of plants, so as to achieve the effect of weedicide.

However, oxalate herbicides also have certain toxicity, and they need to be applied according to the dosage on the instructions to avoid overuse. Secondly, it is recommended to use organic herbicides, which are less harmful to the environment and plants. The main ingredient of organic herbicides is natural plant extracts or microorganisms, which are able to destroy the cell walls of weeds, from acorns to achieve the effect of renting weeds.

However, organic herbicides may not be as effective as chemical herbicides and require multiple applications to achieve the desired effect. Finally, it is recommended to understand the growth habits and growing environment of Tamarix before using herbicides, and avoid using herbicides around Tamarix. At the same time, when using herbicides, you need to pay attention to protect your ** and respiratory tract, and avoid contact with herbicides or inhalation of herbicide odors.

In conclusion, choosing the right herbicide and using it correctly can achieve the effect of weeding and reduce the damage to tamarix. Hopefully, the above suggestions will be helpful to you.
