Atrazine is thus said to have carryover, a generally undesirable property for herbicides. Glyphosate (Roundup) was introduced in 1974 for nonselective weed control. Following the development of glyphosate-resistant crop plants, it is now used very extensively for selective weed control in growing crops.
Toxicological Effects: 1  Acute toxicity: Atrazine is slightly to moderately toxic to humans and other animals. 2  Chronic toxicity: Some 40% of rats receiving oral doses of 20 mg/kg/day for 6 months died with signs of respiratory distress and paralysis of the limbs.
