RE: [compost_tea] Snapshot - a pre-emergent herbicide



 
Active ingredient
Snapshot contains the active ingredients isoxaben and trifluralin. Isoxaben is found in Gallery* specialty herbicide, and trifluralin is a component of Team* Pro specialty herbicide. Snapshot bonds tightly with soil particles and is low in water solubility, so it won't move out of the application zone.

Hazard: Based on results from animal studies isoxzben causes genetic damage and birth defects.  There are data that support the finding that isoxaben has potential to have cancer causing effects on animals.

Residual Soil Activity: Trifluralin is active in the soil. Germination of crops may be impacted for up to 1½ years after soil treatment, especially in arid conditions. It is not usually absorbed from the soil by plants.
