When it comes to lawn and garden management, herbicides are essential tools. One common non-selective herbicide is glufosinate, widely used to control weeds and unwanted vegetation. However, there's often a question about whether glufosinate kills plant roots.

Glufosinate's primary component is glufosinate ammonium, which works by inhibiting the activity of glutamine synthetase (GS) in plants, leading to an accumulation of the amino acid glutamine and ultimately disrupting protein synthesis in plant tissues, causing plant death. It's primarily absorbed by plant foliage and stems, then transported throughout the plant's system.

Although glufosinate is mainly absorbed through foliage and stems, it can also have an impact on plant roots. Research on whether glufosinate kills plant roots yields mixed results. Some studies suggest that glufosinate accumulates relatively less in plant roots, thus having limited effects on roots. However, other studies indicate that glufosinate may adversely affect the roots of some plants, particularly at high concentrations or with frequent use.

The impact of glufosinate on plant roots depends on various factors, including the types of plants in the lawn or garden, soil type, and climatic conditions. Some plants may be more sensitive to glufosinate, while others may be more tolerant. Additionally, factors such as soil pH and moisture content may also influence the absorption and efficacy of glufosinate.

Therefore, while glufosinate may have some effect on plant roots, it's generally not as significant as its impact on foliage and stems. To minimize the impact of glufosinate on plant roots, it's advisable to follow proper herbicide application methods, paying attention to the areas of contact with target plants. Additionally, selecting the right herbicide that suits your needs is crucial.
