Product Overview

Specticle is a new and innovative herbicide for warm-season turf that sets a new standard for pre-emergent weed control. It provides up to 8 months of pre-emergent control in warm-season grasses.  Now registered for general turf situations.


Product Description

Delivering an exceptional level of protection against Poa annua, Crowsfoot Grass and Summer Grass, and unmatched use flexibility with a wide application window, Specticle is a great choice as the foundation of your herbicide program.

Benefits of using Specticle include:

  • Superior turf quality and playability
  • Longer residual control
  • Easier application scheduling
  • A significant step for resistance management (new mode of action)
  • A significant reduction of herbicide placed in the environment
  • No concerns about stains or odour

The active ingredient in Specticle, Indaziflam, is a cellulose biosynthesis inhibitor (CBI) and is classified as a Group O herbicide. Specticle works by inhibiting crystalline cellulose deposition in the plant cell wall, affecting cell wall formation, cell elongation and division. Consequently, actively growing meristematic regions are affected.  Like other pre-emergent herbicides, CBIs do not prevent seeds from germinating. However, once the weed seedlings come into contact with the Specticle barrier, the growth is terminated by inhibiting the development of cells within the roots.

Application rates and delivery

As a pre-emergent herbicide, Specticle should be applied before weed seeds germinate.

1. Best practice is to irrigate with 3-6mm water as soon as practical after application.

2. Adequate soil moisture is needed to activate Specticle and provide maximum control. Clean-up with caution The sprayer must be thoroughly decontaminated before being used again to spray susceptible plants or turf. Ensure that the following operation is carried out in an area that is clear of waterways, desirable vegetation and tree roots, and preferably in an area where drainings can be contained.

See Product Label for further instructions.                           

Specticle is not expected to control weeds that have already emerged prior to application or perennial weeds emerging from rhizomes and roots.

Specticle may affect sensitive grasses down slope from treated areas after excessive rainfall. To minimize effects on sensitive grasses, irrigate after application as directed on the Specticle label. Local conditions such as soil compaction, slope, amount and timing of irrigation or rainfall and sensitivity and growth stage of non-target plant species may affect the severity of damage.
