Atrazine

Atrazine is a selective pre - and

post-seedling herbicide. It is

mainly absorbed by roots, rarely

absorbed by stems and leaves. It

is rapidly transmitted to plant

meristem and leaves, which

interferes with photosynthesis and

causes weeds to die. In resistant

crops such as maize, it is

decomposed by enzyme to

produce non-toxic substances, so

it is safe for crops
