Which of the following is NOT a way in which translocated herbicides kill plants?

Translocated herbicides kill plants by being absorbed and then moving throughout the plant to reach various tissues, where they disrupt vital physiological processes. When considering the mechanism of contact, translocated herbicides specifically rely on being absorbed, primarily through leaves or roots, so that they can travel through the plant systems.

When contact occurs, it typically refers to herbicides that kill plants by direct contact with plant tissues, often not capable of moving or being translocated within the plant. These types of herbicides function by affecting the area they come into direct contact with rather than moving through the plant’s vascular system. Thus, while absorption through roots and leaves and movement throughout the plant are key components of how translocated herbicides operate, killing through contact does not involve the translocation aspect, making it the correct choice as the method that does not apply to translocated herbicides.
