It functions by inhibiting photosynthesis and thus is a nonselective herbicide.

Tests found evidence of Velpar, an herbicide that inhibits photosynthesis and is used specifically to kill hardwood trees.

An impact of that magnitude would then create a large dust cloud that would block sunlight and inhibit photosynthesis for many years.

After Spike is applied, rainfall takes it into the soil where it enters plant roots and inhibits photosynthesis.

To begin with, the coal ash will block enough sunlight to inhibit photosynthesis, a major source of the ocean's dissolved oxygen.

Like atrazine, a related triazine herbicide, it acts by inhibiting photosynthesis.

As an herbicide, paraquat acts by inhibiting photosynthesis.

It is absorbed by the roots and transported to the leaves, where it inhibits photosynthesis.

In addition, it is advisable to wash the dust off the leaves occasionally, as a buildup might inhibit photosynthesis.

One of the consequences of such an impact is a dust cloud which would block sunlight and inhibit photosynthesis for a few years.
