Herbicide used to kill unwanted plants, such like trees, herbs, grasses, etc. According to it’s funktion herbicides kill specific targets while leaving the desired crop relatively unharmed. Some of these act by interfering with the growth of the weed and are often based on plant hormones. Herbicides used to clear waste ground are nonselective and kill all plant material with which they come into contact.
Herbicides are widely used in agriculture and in landscape turf management. In the USA, they account for about 70% of all agricultural herbicide use.

Newton 486 SL is the brand name of a systemic, broad-spectrum herbicide with active ingredient Glyphosate produced by the company PT. Anugerah Agrokimia Indonesia, which located in north Sumatra, Indonesia.
With other word, the active ingredient of Newton 486 SL is the isopropylamine salt of glyphosate. Glyphosate's mode of action is to inhibit an enzyme involved in the synthesis of the amino acids tyrosine, tryptophan and phenylalanine. It is absorbed through foliage and translocated to growing points. Weeds and grass will generally re-emerge within one to two months after usage. Because of this mode of action, it is only effective on actively growing plants or as as a post-emergence herbicide.

Glyphosate was introduced in 1974 for non-selective weed control. It is now a major herbicide in selective weed control in growing crop plants due to the development of crop plants that are resistant to it. The pairing of the herbicide with the resistant seed contributed to the consolidation of the seed and chemistry industry in the late 1990s.

Many modern chemical herbicides for agriculture are specifically formulated to decompose within a short period after application. This is desirable as it allows crops which may be affected by the herbicide to be grown on the land in future seasons.
