Weed Killer – Selective and Non-Selective Herbicides

Weed killer is an important part of all grounds maintenance routines. The spring and summer months bring upon many unwanted weeds around desired vegetation including cropland areas and aquatic settings. Choosing the best weed killer for your specific application will ensure thorough and long lasting weed control.

Selective herbicides are used in delicate grassy areas to combat the problem of pesky weeds. Contained in their special formulas is the power to fight the toughest broadleaf weeds in lawn and ornamental turf without harming the surrounding vegetation. Selective weed killer is made for use against weeds like Dandelion, Ground Ivy, Johnsongrass, Morning Glory, Peppergrass, Poision Ivy/Oak, Primrose, Ragweed and Thistle.

Non-selective herbicides can achieve bare ground results in areas inundated with the most persistent unwanted weeds. The active ingredients in non-selective weed killers have been specially formulated to swiftly knock out the toughest perennial weeds and to prevent new weeds from growing for a long period of time. These herbicides are best for use in locations like ditches, brick paths, railroad tracks, fence rows, parking lots and patios. Some of these products only work on the plants they are sprayed on and they become inert when they come into contact with soil. Others will soak into the soil as well and prevent regrowth longer and more thoroughly.

Common weed killer ingredients include:

  • 2,4-D / 2,4-D Salts – Mimics the activity of a growth hormone inside the flora. It induces unusually speedy development which strains the life support system of the weed to a level where death takes place.
  • Bromacil – A residual weed killer which acts as a soil sterilant to prevent vegetation regrowth for a broadened time period. Acts slowly as it is channeled to the root zone by moisture and absorption.
  • Glyphosate – Enters the metabolism of the weed and suppresses its maturation. Systemic action kills the entire plant, roots and leaves. Becomes dormant upon touching soil.
  • Diquate Dibromide – Once ingested, it interrupts the photosynthesis process and kills the uninvited plant. This contact herbicide eradicates surface vegetation so replanting can take place shortly after application. Deactivates upon contact with the dirt. It can also be utilized to wipe out aquatic weeds.
  • MSMA – An active herbicide element formulated to interfere with the plants metabolism by causing excessive stress to the normal growth cycle.
  • MCPP / 2,4-DP / 2,4-D – A group of systemic weedkillers designed to kill particular broadleaf weeds. Once absorbed into the plant, they kill them by cutting off crucial metabolic processes within.
  • Prometon – Works through root and leaf absorption for “Total Kill” effects. This photosynthesis suppressing herbicide acts as a soil sterilant to contain regrowth and new seedlings.
