| | Atrazine |
 | | Atrazine is used on chlorsulfuron-resistant Phalaris (grass weed) in the fallow or in crops such as sorghum [95] and glyphosate-resistant weed species in fruit crops [30]. | | | Atrazine is also used for weed control in conservation tillage farming systems, for seed bed establishment prior to planting sorghum, or for fallow maintenance prior to wheat, peas or lupins. | | | Atrazine should be retained [9, 31, 3, 54, 64, 132] for use on maize, sweetcorn, grain sorghum. |

| | Questions and Answers about Atrazine; G93-1158-A |
| | Atrazine is a herbicide that selectively controls broadleaf (dicot) weeds, such as pigweed, cocklebur, velvetleaf and certain grass weeds in fields of corn and sorghum. | | | Atrazine may be safely applied to winter wheat, rye or spring grain stubble in the fall for control of volunteer and other weeds in preparation for no-till planting of corn or sorghum the following spring. | | | Atrazine absorbed by corn or sorghum leaves is readily metabolized and is not detrimental to those crops. |

| | Atrazine Poisoning Worse Than Suspected |
| | Worlwide, atrazine is a leading agricultural chemical, and so extensively used that it has been identified as a significant pollutant in surface water, groundwater, in offshore areas and in the atmosphere. | | | Prompt action to limit further pollution from atrazine may be delayed by the development of "super weeds" from current herbicide tolerant GM crops, and volunteer crops or weeds that develop multiple-herbicide tolerance by gene flow between commercial varieties. | | | Atrazine can be present in parts per million in agricultural run-offs and can reach 40 parts per billion in precipitation. |

| | Atrazine |
| | Atrazine is mainly applied to corn and soybean crops, but is also used on sorghum, sugarcane, pineapple, and Christmas tree farms. | | | Atrazine is carried by water into the soil and other water bodies. | | | Atrazine has entered surface water and groundwater mainly through runoff from herbicides used in row crops and wastewater from manufacturing facilities. |

| | Atrazine (HSG 47, 1990) |
| | Atrazine is a selective pre- and post-emergence herbicide used for the control of weeds in crops, such as asparagus, corn, sorghum, sugar cane, and pineapple. | | | Atrazine is virtually non-toxic for bees, but is moderately toxic for aquatic organisms (96-h LC range from 0.5 to 15 mg/litre). | | | SUMMARY AND EVALUATION 2.1 Human Exposure to Atrazine Highest human exposure to atrazine is associated with its production and its use in agriculture. |

| | BMP - ATRAZINE |
| | Atrazine (or atrazine tank mix products) can be incorporated into the top two inches of soil with a field cultivator, tandem disc or other implement. | | | Early-applied atrazine is more likely to get moved down into the soil by gentle rains of early spring than swept off the field by runoff water during intense late spring and early summer storms. | | | Benefit: Less atrazine is present at the soil surface, where it is most vulnerable to runoff. |

| | G4851 Atrazine: Best Management Practices and Alternatives in Missouri, MU Extension |
| | Atrazine is used on about 65 percent of all corn acreage and 69 percent of all grain sorghum acreage in the United States, and Missouri mirrors this level of use. | | | This is because atrazine moves primarily through solution in runoff water (the water phase) rather than attachment to soil particles (the sediment phase). | | | Broadcast spray application rates for atrazine before crops emerge depend on the amount of plant residue covering your field at planting and on the erodibility of your soil as defined by NRCS. |
