Blockade is a selective pre-emergent herbicide that provides residual control of weeds in established turf. This is commonly known as Barricade in New Zealand. NZLA is the only supplier of this product in smaller pack sizes in New Zealand.

Blockade Herbicide controls susceptible weeds by interfering with cell division in the root tips of newly germinated weeds.

Blockade contains 480 g/L Prodiamine in the form of a suspension concentrate (SC).

What established turf can Blockade Herbicide be used in listed;

  • Bahia Grass (Paspalum notatum),

  • Carpet Grass (Axonopus affinis, Axonopus compressus),
  • Couch, Common (Cynodon dactylon),
  • Couch, Hybrid (Cynodon dactylon x Cynodon transvaalensis),
  • Kikuyu (Pennisetum clandestinum),
  • Qld Blue Couch (Digitaria didactyla),
  • Seashore Paspalum (Paspalum vaginatun),
  • Zoysia (Zoysia japonica, Zoysia matrella)

 

What weeds is Blockade Herbicide registered to control;

  • Barnyard Grass (Echinochloa crus-gali),
  • Crab Grass (Digitaria sanguinalis),
  • Parramatta Grass (Sporobolus africana),
  • Rat’s Tail Fescue (Vulpia myuros),
  • Summer Grass / Crab Grass (Digitaria sanguinalis)
  • Crowsfoot Grass (Eleusine indica)

  • Bahia Grass (Paspalum notatum),
  • Kentucky Blue Grass (Poa patensis)
  • Paspalum (Paspalum dilitatum)
  • Winter Grass (Poa annua)

 

Blockade Herbicide’s selectivity is primarily through soil profile placement.  Achieving this soil profile placement of Blockade Herbicide correctly is vital to obtain high efficacy.  Applicators should ensure an even matrix flow through the soil profile to achieve a consistent and even zone of herbicide activity.

After application, plants that have the majority of their root system in the herbicide profile zone cannot effectively absorb the water and nutrients required for root and plant development. Therefore, good even coverage and incorporation is required to ensure the weeds cannot recover by establishing roots outside the zone of herbicide activity.

Small seeded plants (i.e. annual grass weeds) are affected more by the herbicide than established grasses as they germinate in the soil profile zone of herbicide placement (i.e. 100% of their germinating root system is affected by the herbicide).

Warm-season grasses can be less prone to root inhibition due to the fact that they have multiple fibrous root systems with established roots beyond the depth of the zone of herbicide activity and are therefore are still able to obtain moisture and nutrients.

Weed control in turf is most effective when Blockade Herbicide is activated by at least 6 mm of rainfall or irrigation before weed seeds germinate and within 7 days after application.

Option to tank mix with Glyphosate to treat gravel pathways and fence lines offering knock-down and pre-emergent in one application for up to 6 months of weed control.

Light post-application irrigation ensures the product is washed off the foliage and moved into the top couple of centimetres of the media providing the opportunity to bind and establish the weed control band.

Application rate 40-80ml/100m²

Great customer service.
Glad I bought the protection. The vaccume worked great for a while then quit holding a charge. They refunded my purchase price (Amazon gift card).

Game changer..get one!
My floors had varying levels of dirt (think heavy traffic area vs lighter traffic areas) and the detection system masterfully targeted areas until they were super clean. This is a good value, time saving and elevated my quality of life.

Works great, might have to use distilled water if you have hard water
So far it's great! It uses a LOT of water on the first clean (and maybe also because of using the 'Freo' ai mode) you can use tap water, but in areas with hard water, you might need to go through a lot of distilled water. I think on future cleaning jobs it's supposed to use less water though. And you can adjust the cleaning level to a lower setting so that it doesn't use as much. The app takes a little while to get used to, because there are many options and menus. But still very nice to have and use. The vacuum has a dust bin with a very basic filter (needs replaced every 30 days if used), but if you want more of 'Hepa' clean air, you would have to use another type of vacuum before mopping. It also doesn't get close to the edges of some areas for some reason, even thought it could fit. Still, for what it is, it's a great product that will cut down on a lot of mopping time.

Worth every penny. Highly recommend!
To say I love my Narwal robotic mop and vacuum is an understatement—total game changer. I can’t imagine going back to any other robotic vacuum. I have two dogs, including a Jack Russell who sheds like Pig-Pen from Peanuts—basically a walking cloud of hair—and this thing handles it effortlessly. The vacuum + mopping combo is amazing, and it’s so easy to use and maintain. It truly does all the dirty work for me. I did have a small hiccup about two months in, but Narwal support helped me reset it quickly and it’s been perfect ever since (I definitely panicked for a minute 😅). Worth every penny. Highly recommend!
