Triad QC Select combines quinclorac, 2,4-D and dicamba to provide broad-spectrum control of grassy and broadleaf weeds.

Triad QC Select

Triad QC Select has a powerful combination of three active ingredients ( 2-4, D, Quinclorac, and Dicamba) to provide post-emergent control of hard-to-control weeds. Use Triad QC Select to control broadleafs such as clover, chickweed, dandelion, knotweed, oxalis, plantain, black medic, thistle, cocklebur, henbit, plantain, spurge, and more listed weeds. The Quinclorac part of this formulation is absorbed through the foliage and roots to control grassy weeds like crabgrass, signalgrass, foxtail, and barnyardgrass.

It controls the crabgrass from newly germinated 1-2 leaf crabgrass, 1-tiller crabgrass, to mature crabgrass with 5-tillers or greater.

Triad QC Select is handy to use in the late season for areas that didn't receive a pre-emergent application in the spring months.

Triad QC Select-Broad-Spectrum Control of Grassy and Broadleaf Weeds

  • Post-emergent control of a comprehensive list of both grassy and broadleaf weeds.
  • Excellent clean up product for areas that did not receive a pre-emergent grass herbicide application in the spring.
  • Controls newly germinated 1- to 2-leaf crabgrass, to 1-tiller crabgrass and when crabgrass has matured to 5-tillers or greater.
  • Quinclorac contributes grassy weed control and is absorbed by foliage and roots and translocated throughout the plant.

Triad QC Select-Mode of Action and Herbicide Resistance Management

Triad QC Select belongs to the synthetic auxin Group 4 Herbicides that interfere with plant cellular development and growth.Susceptible grasses demonstrate stunting, chlorosis, and gradual reddening followed by necrosis and death.

To reduce the potential for weed resistance:

  • Ensure that good spray coverage is achieved with proper spray volumes and calibrated equipment.
  • Plant into weed-free fields and keep fields as weed-free as possible.
  • Where possible, avoid the repeated use of herbicides with the same mode of action (i.e., same group number) in successive seasons either in cereal crops or rotational crops.
  • See label for more tips for best management practices.
