Safe Use of Herbicides Around Water

  • Prevention and Containment

  • Surveying and small-scale eradication

  • Management

    • Chemical

    • Grazing management

    • Biological


Prevention and containment l.jpg

Prevention and Containment

  • Limit weed seed dispersal

    • Limiting vehicles

    • Washing vehicles and equipment

    • Weed free seed

    • Holding livestock before introducing

    • Education to land-users


Prevention and containment5 l.jpg

Prevention and Containment

  • Limit weed seed dispersal

  • Contain neighboring infestations

    • Contain the encroaching borders that can be easily controlled

    • Funnel livestock or wildlife to easily controlled areas


Prevention and containment6 l.jpg

Prevention and Containment

  • Limit weed seed dispersal

  • Contain neighboring infestations

  • Properly manage desirable vegetation

    • Competitive plants

    • Proper grazing management


Systematic surveys and then small scale eradication l.jpg

Systematic surveys and then small-scale eradication

  • Key point….systematic and methodical (2-3 times/year)

  • Early detection makes for easy eradication

  • Combine surveys and eradication with good record-keeping

    • Helps determine # of years for control

    • Effectiveness of control methods

    • Response of both weed and desirable vegetation


Management l.jpg

Management

  • Chemical

  • Biological

  • Prevention


Chemical management l.jpg

Chemical management

  • At best the most you can hope for is seed management.

  • Total eradication of large patches is almost impossible

  • Flowing water or ditchbank

Herbicides for ditchbanks l.jpg

Herbicides for Ditchbanks

  • Make sure its labeled for ditchbanks

  • Choose a herbicide with:

    • Low persistence

    • Low water solubility

  • Time your application when runoff is unlikely

  • Prevent physical drift


Solubility l.jpg

Amount of chemical that can be dissolved into a solution

Expressed as parts per million.

> 30 ppm means high solubility = high tendency to leach or runoff.

Tordon = 400- 430

2,4-D = 890

Assert = 1370

Ally/Escort

1750 (pH 5)

2790 (pH 7)

213,00 (pH 9)

Paraquat = 7000

Roundup = 12,000

Solubility

Salt – 900,000 ppm


Common herbicides used l.jpg

Common Herbicides Used

  • Some 2,4-D products

  • Rodeo

    Less commonly use products include:

    * Garlon

    * Krenite


Herbicides 2 4 d l.jpg

Herbicides – 2-4,D

  • Various labels in Montana

    • Amine 4 Selective Weed Killer – Wilbur-Ellis

    • 2,4-D Amine No.4 – Wilbur Ellis

    • Amine 400 – PBI Gordon

  • Some labels allow for overspray onto water


Herbicides rodeo l.jpg

Herbicides - Rodeo

  • Roundup labeled for aquatic uses

  • Do not apply within ½ mile of potable water intake

  • Must use approved (labeled) surfactants

  • Non-selective


Herbicides krenite l.jpg

Herbicides - Krenite

  • Do not apply to open water or where there is a danger of runoff.

  • Used mainly for woody and brushy species

    • Take care with non-target species


Herbicides garlon l.jpg

Herbicides - Garlon

  • Do not apply to open water or below the high water mark

Biological control l.jpg

Biological Control

  • Slow acting but reduces seed production and stresses plants

  • KP… A main goal of riparian weed management is to control weeds immediately to prevent seed dispersal by moving water
