Low temperatures have a significant impact on herbicide efficiency, primarily by slowing down growth and absorption in plants. At reduced temperatures, the metabolic processes of plants tend to decrease, which results in a slower uptake of nutrients, water, and, importantly, herbicides. This reduced absorption limits the effectiveness of the herbicide, as the active ingredients are not taken up by the plant in sufficient quantities to achieve the desired control over the target pests.

Additionally, low temperatures can contribute to a general slowdown in physiological processes within the plant, making it less responsive to herbicides. Even though the herbicides may be applied correctly, the chilling temperatures hinder the plants' ability to metabolize and respond to the chemical, resulting in diminished herbicidal action.

In contrast, higher temperatures typically enhance plant growth and metabolic activity, leading to increased herbicide uptake and effectiveness. Thus, understanding the influence of temperature on herbicide efficiency is crucial in aquatic pest management strategies to maximize control over unwanted vegetation.
