ISP ProForce Numchuk Quad Herbicide

ISP ProForce Numchuk Quad Herbicide

Numchuk Quad is a non-selective knockdown and residual herbicide featuring Quad Control Herbicide Technology to provide effective post and preemergence weed control for up to 12 months.

Numchuk Quad contains 100g/L Glyphosate, 60g/L Amitrole, 15g/L Oxyfluorfen and 350g/L Terbuthylazine – 4 herbicides from different mode of action groups.

Numchuk Quad is registered to control most annual, perennial and broadleaf weeds in commercial and industrial areas including rights of way, roadsides, railway lines, guideposts, powerlines and substations, aerodromes, public utilities and fencelines.

Key Features

  • Contains Quad Control Technology, and multiple modes of action, reducing potential weed resistance issues.
  • Very effective on hard-to-kill weeds like Fleabane and Giant Rats Tail.
  • Substantial labour savings for weed management on road and rail situations.
  • Provides both knockdown and residual control – reducing the need for additional tank mixes.
  • Has strong activity on both grasses and broadleaf weeds.
  • Provides long-term residual control – up to 12 months or greater.
  • Can be used via handgun or boom application.
  • Safe to established trees and ornamentals, as long as spray drift doesn’t occur.

Mode of Action

GROUP C M Q G HERBICIDE

Glyphosate, one of the active ingredients in Numchuk Quad Herbicide, controls weeds by inhibiting the activity of the EPSP enzyme (5-enolpyruvylshikimic acid-3-phosphate synthase), which is necessary for the formation of the aromatic amino acids within the plant.

Amitrole’s mode of action isn’t well understood, but it is believed to be an inhibitor of several important enzymes. One of which is lycopene cyclase which is involved in carotenoid production. Carotenoids are essential components of photosynthesis, playing an important role in preventing photo-oxidative damage.

Oxyfluorfen targets a specific enzyme, protoporphyrinogen oxidase (PPO), in the chlorophyll pathway. Inhibiting PPO in plants leads to an accumulation of phototoxic chlorophyll precursors which, in the presence of light, rapidly disrupt cell membrane integrity.

The mode of action for Terbuthylazine appears to be due to a herbicide-produced deficiency in the growth regulator photosynthtate, caused by inhibition of photosynthesis.
