What Is Simazine?

The herbicide active ingredient simazine is used as a pre-emergence herbicide used for control of broad-leaved and grassy weeds on a variety of deep-rooted crops such as artichokes, asparagus, berry crops, broad beans, citrus, etc., and on non-crop areas such as farm ponds and fish hatcheries. Its major use is on corn where it is often combined with AAtrex. Other herbicides with which simazine is combined include: paraquat, on apples, peaches; Roundup or Oust for noncrop use; Surflan on Christmas trees; Dual on corn and ornamentals.

Simazine is an organic white solid compound which is sparingly soluble in water. It is a member of the triazine-derivative herbicides, and was widely used as a residual nonselective herbicide

How Does Simazine Work?

Simazine's mode of action is that it interferes with photosynthesis, especially inhibiting photosystem II. Photosynthesis— unique to green, living plants—happens when light energy is converted to chemical energy needed for food production. Simply put, when food production stops, plants eventually starve to death. Simazine selectively kills non-desirable plants (weeds). This interferes with product growth and causes the plant to die. Simazine works as both a pre-emergent when applied to the soil and post-emergent onto the grown plants themselves making it quite a versatile herbicide. It also eliminates weed competition, making all the soil nutrients and moisture go to the crop rather than the weed.

The risk of acute exposure would be primarily to chemical applicators; concentrated simazine does not pose an inhalation risk, but can cause some skin and eye irritation. Recreational users of a water body would not be exposed to concentrated simazine.
