Pre-emergent herbicides have been developed for their long residual effect; however, they can make sensitive successor cultures unfeasible. Waste remediation techniques are needed for sustainable agricultural systems; for this, the edaphoclimatic asymmetries in the country must be considered. This study aimed to evaluate the remedial capacity of the herbicide diclosulam by covering crops under different edaphoclimatic conditions. Treatments were arranged in an × 2 factorial scheme, the first factor being the number of plant species in each location and the second being the presence or absence of diclosulam in the soil. The physiological and growth characteristics of 15 potential phytoremediation species were evaluated. Herbicide residues in the environment were positively correlated with the soil pH; organic matter, aluminum, and silt contents; and aluminum saturation. The effectiveness of phytoremediation varied between species and between regions. Plant species suitable for efficient phytoremidation systems of diclosulam residues were for Couto Magalhães de Minas, and for Diamantina, for Erechim and for São João Evangelista.
已开发出具有长效残留作用的芽前除草剂；然而，它们可能使敏感的后继培养物变得不可行。需要有废物修复技术来支持可持续的农业系统；为此，必须考虑到该国的土壤气候不对称性。本研究旨在通过在不同的土壤气候条件下覆盖作物来评估除草剂氯氟吡氧乙酸的修复能力。处理方式采用 2 因素析因设计，第一个因素是每个地点的植物物种数量，第二个因素是土壤中是否存在氯氟吡氧乙酸。评估了 15 种潜在的植物修复物种的生理和生长特性。环境中的除草剂残留与土壤 pH 值、有机质、铝和粉粒含量以及铝饱和度呈正相关。植物修复的效果因物种和地区而异。对于库托·马加良斯·德·米纳斯，和对于迪亚曼蒂纳，对于埃雷欣和对于圣若昂·埃万热利斯塔，是用于高效去除氯氟吡氧乙酸残留的植物修复系统的合适物种。
