For the experiment with 7 herbicides applied in pre-emergence, atrazine (D = 2500 g [ha.sup.-1]), atrazine + mesotrione (D = 1200 + 120 g [ha.sup.-1]), atrazine + simazine (D = 250 + 250 g [ha.sup.-1]), isoxaflutole (D = 60 g [ha.sup.-1]), pendimenthalin (D = 1500 g [ha.sup.-1]), trifluralin (D = 2400 g [ha.sup.-1]) e s-metolachlor (D = 1400 g [ha.sup.-1]) were evaluted.
atrazine (triazine), metolachlor (chloroacetanilide), carbaryl (carbamate), and chlorothalonil (chloronitrile) have high usage rates (Solomon et al., 1996), are prevalent in streams (Larson et al, 1999), and co-occur more often as mixtures than as individual pesticides (Gilliom, 2007).
Atrazine (6-chloro-N-ethyl-N-isopropyl-1,3,5 -triazinediyl-2,4-diamine; (IUPAC) has become one of the most widely used as a selective pre-emergence and post-emergence herbicide for the control of weeds in a variety of agricultural crops [11].
Atrazine, a restricted-use, triazine herbicide used to inhibit the growth of broadleaf and grassy weeds in the production of corn and other crops, is one of the most commonly used pesticides in the U.S., with approximately 75 million pounds used in 1997 and nearly 80 million pounds used in 2007 (Grube, Donaldson, Kiely, & Wu, 2011; Kiely, Donaldson, & Grube, 2004).
