Lecture 8 - Recommendations for Specific Species

Must kill the roots!

• Apply Picloram to soil or to foliage

• Power grubbing

Redberry Juniper

Kill the pads

• Spray with Picloram

• Be sure to cover all pads!

Best Option = Prescribed Fire + Herbicide

• Be sure you have ample grass to carry a high intensity fire

• Follow with Picloram application

Prickly Pear

Best option is Chemical (aerial)

2, 4‐D + Diesel between May & June

Sand Sagebrush

Topkilling works fine.

• Apply Picloram to soil or to foliage

• Power grubbing

Dozing, Blading, Chaining, Fire, etc.

Ashe Juniper

Mesquite resprouts, so you must kill the roots.

IPT: Basal spray w/Triclopyr

Foliar:

• Soil temp must be 75, Mesquite leaves must be dark green.

• Mix of Triclopyr and Clopyralid

Mechanical:

• Power grubbing, root plowing, etc.

Mesquite

Kill the stems and canes… and the roots

Herbicide

• Spray with Picloram

• Be sure to cover all stems!

Mechanical

• Power Grubbing when soil moisture is good (to ensure root removal)

Cholla

Aerial or IPT Chemical Application

Tebuthiuron Pellets applied in Oct‐April

Shin-Oak

Chemical Control

• Arsenal applied July‐Sept

Must revegetate with desirable species

Followup with control of regrowth

Salt Cedar

Chemical Control, either aerial or IPT

• But don’t IPT the dense “whorls” or colonies

Dicamba or Triclopyr

Yucca

Chemical:

• Apply Plateau or Round-up

Grazing

• Graze heavily in early spring (twice, with a short rest between)

Mechanical

• Till or disk in early spring

Cheatgrass

Chemical

IPT (Aerial is not consistently successful)

Mix of:

• GrazonNext HL 2.1pt/ac

• Tordon 22K 13oz/ac

• Grazon P+D 72oz/ac

Mechanical

• Get the roots out!

• Power Grubbing
