Most state cooperative extension services now recommend a pre-emergent application strategy to control Roundup-resistant weeds. To make this strategy even more effective, you should add ORO-RZ to every pre-emergent application.

Hydrophobic soil areas left untreated can allow weed seeds to germinate, thus requiring a post-emergent application to control. A tank mix of ORO-RZ with a pre-emergent herbicide delivers a uniform soil treatment to provide even distribution, resulting in dramatically reduced weed growth.

ORO-RZ is the most advanced soil adjuvant for combating tough and Roundup-resistant weed growth, including broadleaf weeds like marestail. By delivering a uniform soil treatment of herbicide and providing even distribution, the ability of weed seeds to germinate is dramatically reduced. Improved weed control results are realized with a tank mix of ORO-RZ.

Broadleaf control on weeds in Alion trial

• Marestail
• Fleabane
• Spotted Spurge
• Redstem Filaree
• Common Chickweed
• Redmaids
• Shepherd’s Purse
• Annual Sow Thistle
• Little Mallow
• California Burclover
• Redroot Pigweed

IMPROVED PRE-EMERGENT HERBICIDE INFILTRATION

Soil-applied herbicides may not penetrate dense and hydrophobic pockets in soil, allowing weed seeds to germinate and grow. Mixed with ORO-RZ, herbicides infiltrate more thoroughly and penetrate pockets of denser soil delivering better control.

BROADLEAF CONTROL

ORO-RZ improved the efficacy of Alion herbicide from 71% to 95% across a variety of late winter broadleaf weeds.
