Atrazine applied at planting is commonly used for weed control in corn. With global climate change causing an increase in river flooding in the United States over the past decade, producers need information to determine the best course of action in flooded fields treated with atrazine into which they wish to immediately plant soybean. Studies were designed to understand the effect of flooding on atrazine residual activity including atrazine concentration, soybean injury, and soybean yield. In 2012, soybean yield in flooded treatments was reduced by prior atrazine application. In 2014, soybean injury was <10% in all plots, and nonflooded, atrazine-treated soils had yields equal to the nontreated. Findings from this research indicated that it is possible for producers to consider replanting soybean after atrazine application, with appropriate changes to product labeling.

淹水和非淹水土壤中的阿特拉津残留及对大豆的影响

种植时施用的阿特拉津通常用于玉米的杂草控制。在过去十年中，随着全球气候变化导致美国河流泛滥的情况增加，生产商需要信息来确定在用阿特拉津处理过的淹水田地中他们希望立即种植大豆的最佳行动方案。研究旨在了解洪水对阿特拉津残留活性的影响，包括阿特拉津浓度、大豆损伤和大豆产量。2012 年，淹水处理的大豆产量因先前施用阿特拉津而降低。2014 年，所有地块的大豆损伤率均小于 10%，未经淹水、阿特拉津处理的土壤的产量与未经处理的土壤相同。这项研究的结果表明，生产者可以考虑在施用阿特拉津后重新种植大豆，
