Precautions Regarding ArmorTech Tetra Herbicide

“Tetra is a new, highly active herbicide unlike any other product on the market.

Tetra has fast post-emergent activity on annual and perennial grasses and broadleaf weeds – including creeping bentgrass, crabgrass, nimblewill, goosegrass and foxtail.

Tetra was thoroughly tested and precautionary language is on the label for things to avoid such as:

• Tank mixing with any other products, fertilizers or surfactants

• Use caution when applying to insure no spray solution collects on the tires of application equipment

• Assure that sprays completely dry prior to entering treated areas as accumulation on tires can lead to tracking

• Avoiding applications during foggy or conditions of high moisture and wet foliage and during periods of cloudy and cool temperatures with rapid growth

Tetra was launched in August this year and we’ve had 3 months of outstanding results.
In the last two weeks, we’ve encountered the conditions outlined above resulting in reduced selectivity to turf resulting in turf damage.  This is all clearly outlined on the label.

So when is right time to spray Tetra?

• Rounds 2, 3 and 4 when the temperatures are warmer, the grass dries out faster and cuticles are thicker.

• Fortunately, that coincides with germination and establishment of the key weeds we are using Tetra to control.

Follow yellow nutsedge as the indicator weed of when to use Tetra.  If you see yellow nutsedge in yards – you can spray Tetra.”
