I would like to ask what pesticides are powerful in weeding?

The herbicides with good weeding effect are glyphosate, paraquat, chlorpromazine and naproxen. These herbicides are all effective, and basically the effect can be achieved once.

Herbicide is a substance that can completely or selectively kill weeds, also known as herbicide, to eliminate or inhibit plant growth. Among them, sodium chlorate, borax, arsenate and trichloroacetic acid have lethal effects on any plant, and their effects are affected by herbicides, plants and environmental conditions. According to their functions, they can be divided into two categories: killing herbicides and selective herbicides. Most selective herbicides, especially derivatives of nitrophenol, chlorophenol and carbamic acid, are effective. The development of herbicides in the world is gradually stable, mainly developing varieties with high efficiency, low toxicity, broad spectrum and low dosage, and disposable treatment agents with little environmental pollution are gradually becoming the mainstream.
