Use glyphosate.

Glyphosate is a herbicide developed by Monsanto in the United States. Also known as: Zhencaoning, Nongda, glyphosate, phosphoric acid. The pure product is a non-volatile white solid with a specific gravity of 0.5 and a melting point of about 230℃, accompanied by decomposition. The solubility in water at 25℃ is 65438 0.2%, insoluble in general organic solvents, and its isopropylamine salt is completely soluble in water. Non-flammable, non-explosive and stable at room temperature. Corrosive to medium carbon steel and tinplate.

Many authoritative regulatory agencies around the world have made continuous safety assessment of glyphosate, and finally reached a unanimous conclusion that glyphosate, as one of the important and efficient agricultural tools, has a good long-term safety record and has been applied in more than 60 countries around the world.

Monsanto Roundup gel herbicide (active ingredient: glyphosate) has been registered and approved in Germany recently, and it is expected to be listed in the horticultural crop planting season of 20 16.
