Damage to deciduous trees from a direct glyphosate application would have which of the following symptoms?

Damage to deciduous trees from a direct glyphosate application typically manifests as yellowing and dieback of foliage. Glyphosate is a systemic herbicide that is designed to inhibit specific pathways in plants, effectively disrupting their growth and function. When applied incorrectly or inappropriately to deciduous trees, the compound can cause the leaves to begin chlorosis, which is characterized by yellowing due to a failure of the leaves to produce chlorophyll.

As the herbicide disrupts the metabolic processes, the affected parts of the tree may suffer from a lack of nutrients and energy, leading to dieback. This means that not only do the leaves turn yellow, but they may also deteriorate, with symptoms appearing as browning, wilting, or even complete loss of the foliage.

In contrast, other symptoms associated with plant stress or herbicide injury, such as excessive flowering or sprouting of new shoots, would not typically arise from glyphosate damage. Such symptoms are indicative of different kinds of stress or growth responses that are not directly related to the hormonal disruption caused by glyphosate.
