Abstract

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 n × 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 Canavalia ensiformis for Couto Magalhães de Minas, Cajanus cajan and Canavalia ensiformis for Diamantina, Raphanus sativus for Erechim and Cajanus cajan for São João Evangelista.

摘要

已经开发出芽前除草剂，因为它们具有长效的残留作用。但是，它们会使敏感的继任者文化变得不可行。可持续农业系统需要废物补救技术；为此，必须考虑该国的人际气候不对称性。这项研究旨在通过覆盖不同水生气候条件下的农作物来评估除草剂双氯舒兰的修复能力。处理被安排在一个Ñ ×2阶乘方案，第一个因素是每个位置的植物物种数量，第二个因素是土壤中是否存在双氯磺草胺。评价了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呈正相关。有机物，铝和淤泥含量；和铝饱和。植物修复的有效性在物种之间和地区之间有所不同。适于diclosulam残基的高效phytoremidation系统植物物种是刀豆为Couto的Magalhães的米纳斯，木豆和刀豆为迪亚曼蒂纳，萝卜为埃雷欣和Cajanus cajan，代表SãoJoãoEvangelista。
