Specticle 20 WSP Pre-Emergent Herbicide

SPECTICLE 20 WSP is a selective, preemergence alkylazine herbicide for use on warm season turfgrasses. It is not intended for post emergent application. SPECTICLE 20 WSP HERBICIDE controls many annual grasses including crabgrass, goosegrass, annual bluegrass, annual sedges, and broadleaf weeds in turf, ornamentals (residential), hedgerows, hardscapes, Christmas trees, and conifers. SPECTICLE 20 WSP HERBICIDE can be used only on established turf in areas including golf courses (roughs, tees, and fairways), sod farms, sports fields, lawns, both home and commercial, parks and cemeteries. SPECTICLE 20 WSP HERBICIDE controls weeds by reducing the emergence of seedlings through inhibition of cellulose biosynthesis (CB Inhibitor). Necrosis or yellowing may be observed if the herbicide is applied to herbaceous tissue such as leaves and green stems of susceptible plants. SPECTICLE 20 WSP HERBICIDE does not control tubers, rhizomes, bulbs, corms, existing rootstocks, and woody vegetation.
The herbicide needs to be activated prior to weed germination for most effective control. For maximum activity against germinating weeds, SPECTICLE 20 WSP HERBICIDE requires rainfall or
irrigation prior to weed germination. For use on sod farms, golf courses, and non-crop areas (excluding lawns), do not apply within 25 feet of ponds, lakes, rivers, streams, wetlands, and habitat containing aquatic and semi-aquatic plants.

March 17, 2014Dee from Fla asked:

QHow on earth are you able to get good penetration AND coverage of 1000 sq. ft. with ONLY One Gallon of water ?
Is it not customary for 3-5 gallons per 1000 sq. ft. At least most label instructions... So, How on earth, WITH GOOD Faith, give an answer on a Q&A for someone to spray 1000 sq. ft. with ONLY one gallon of water/mix ???

AWe apologize that you are not happy with some of our previous Q&A responses. You can most certainly get adequate coverage with 1 gallon over 1000 sq/ft but it will depend on the turf area being treated. If it takes you 3 gallons of water to cover 1000 sq/ft to get adequate coverage for your specific yard to your liking, then mix the correct amount of product per 1000 sq/ft with 3 gallons of water. The water is purely the carrier and each applicator is going to walk at a different pace, and have equipment that is calibrated differently, and will apply more and less thoroughly than the next. The rule of thumb used by most professionals if it doesn't state an exact amount on the product label, is actually 2 gallons per 1000 sq/ft.

September 22, 2014Clark from Spartanburg asked:

QIs Manor or Celcuis post emergent safe to use with Specticle pre emergent?

A

Specticle 20 WSP Pre-Emergent Herbicide is generally compatible with many herbicides and liquid fertilizers. A compatibility test should be conducted with any potential tank mix partner with Specticle 20 WSP Pre-Emergent Herbicide*. Using a clear container, conduct the test as described below:

1.Fill the container three-quarters full with water.

2.Add the appropriate amount of Specticle 20 WSP Pre-Emergent Herbicide** and the tank mix partner in the following order:

(a) Specticle 20 WSP Pre-Emergent Herbicide 

(b) dry flowable

(c) aqueous suspensions

(d) flowables

(e) liquids

(f) solutions and emulsifiable liquid concentrates

(g) micronutrients and liquid fertilizers

3. Shake or stir after each addition to mix thoroughly.

4. After adding all ingredients, let the mixture stand for 15 minutes and look for separation, large flakes, precipitates, gels, and heavy oily film or other signs of incompatibility

5. If the compatibility test shows signs of incompatibility, do not tank mix the product tested with Specticle 20 WSP Pre-Emergent Herbicide.

6. If mixing with a liquid fertilizer or micronutrient, add Specticle 20 WSP Pre-Emergent Herbicide to the tank first and make sure it is fully dissolved before adding the fertilizer.

* Do not use Specticle 20 WSP Pre-Emergent Herbicide packets in a tank mix combination with products that contain boron or release free chlorine. The resultant reaction of PVA and boron or free chlorine is a plastic which is not soluble in water or solvents such as diesel oils, kerosene, gasoline, or alcohol.

** Note that a labeled spray rate for Specticle 20 WSP Pre-Emergent Herbicide should be used in any compatibility test. Dilute from a concentrated suspension, or sample from a properly dilutedspray solution. Do not cut the water soluble packs open for any reason.
