At a time when herbicide use is being challenged by the selection of herbicide‐resistant weeds, reliance on other, innovative weed control strategies is becoming increasingly necessary. However, one may question the sustainability of these novel farming practices if weeds adapt rapidly to these non‐chemical selection pressures. Although farmers and agronomists impose many selective processes through farming practices, there is a paucity of literature demonstrating these selection cases in arable fields. In contrast to the relatively simple case of herbicide resistance, random trait association and variability in selection pressures in field conditions could explain why there are so few clear examples of adaptive processes to non‐chemical control in arable fields.

杂草的遗传变异性是否对耕地的非化学选择压力有反应?

在选择抗除草剂杂草的过程中,除草剂的使用面临挑战时,对其他创新性杂草控制策略的依赖变得越来越必要。但是,如果杂草快速适应这些非化学选择压力,人们可能会质疑这些新型耕作方法的可持续性。尽管农民和农艺师通过耕作实践强加了许多选择过程,但很少有文献证明可耕种领域的这些选择情况。与相对简单的除草剂抗性案例相反,田间条件下随机性状关联和选择压力的差异可以解释为什么在耕地中很少有非化学控制适应过程的清晰例子。
