Reclamation of pesticide-polluted lands has long been a difficult endeavour. The use of synthetic pesticides could not be restricted due to rising agricultural demand. Pesticide toxicity has become a pressing agronomic problem due to its adverse impact on agroecosystems, agricultural output, and consequently food security and safety. Among different techniques used for the reclamation of pesticide-polluted sites, microbial bioremediation is an eco-friendly approach, which focuses on the application of resilient plant growth promoting rhizobacteria (PGPR) that may transform or degrade chemical pesticides to innocuous forms. Such pesticide-resilient PGPR has demonstrated favourable effects on soil-plant systems, even in pesticide-contaminated environments, by degrading pesticides, providing macro-and micronutrients, and secreting active but variable secondary metabolites like-phytohormones, siderophores, ACC deaminase, etc. This review critically aims to advance mechanistic understanding related to the reduction of phytotoxicity of pesticides via the use of microbe-mediated remediation techniques leading to crop optimization in pesticide-stressed soils. The literature surveyed and data presented herein are extremely useful, offering agronomists-and crop protectionists microbes-assisted remedial strategies for affordably enhancing crop productivity in pesticide-stressed soils.
受污染土地的复垦一直是一项艰巨的任务。由于农业需求不断增加，无法限制合成农药的使用。由于其对农业生态系统、农业产量的不利影响，因此对食品安全和安全构成了紧迫的农艺问题。在用于受污染场地修复的不同技术中，微生物生物修复是一种环保方法，它侧重于应用具有弹性的植物生长促进根际细菌（PGPR），这些细菌可以将化学农药转化或降解为无害形式。这种对农药具有抗性的 PGPR 通过降解农药、提供大量和微量元素以及分泌活性但变化的次生代谢物（如植物激素、铁载体、ACC 脱氨酶等），对土壤-植物系统产生了有利的影响，即使在农药污染的环境中也是如此。本综述旨在深入了解通过使用微生物介导的修复技术减少农药的植物毒性，从而在受农药胁迫的土壤中优化作物的机制。本文综述了相关文献并呈现了数据，为农业学家和作物保护主义者提供了微生物辅助修复策略，以经济高效地提高受农药胁迫土壤中作物的生产力。
