Simazine appears in weeds, entering them through the roots, unlike many herbicides belonging to group 2, 4-D.
Penetration of the substance into the roots occurs in the first phases of development. Approximately on the 6th day after germination, the growth of seedlings slows down, they turn yellow and then quickly die.
