Product Highlights
  • Knocking out tough and resistant weeds and damaging soil pathogens requires getting your pesticides evenly spread throughout your soil. Missed areas lead to nutrient-stealing weed growth and disease that hurts your bottom line.
  • The ability of ORO-RZ to deliver superior performance of soil-applied pesticides offers you a better return on your pesticide investment through better control of pre-emergent weeds and soil-borne diseases.
  • Get more from every acre by getting more from your pesticides with ORO-RZ.
  • Get the most out of expert-recommended pre-emergent weed control strategies with ORO-RZ soil adjuvant.
ORO-RZ Dramatically Improves Pesticide and Fertilizer Performance
  • Distributing pre-emergent herbicides evenly to prevent gaps that would otherwise allow weed growth.
  • Surrounding vulnerable in-soil portion of crops with pesticides to protect them against infestation.
  • Eliminating hydrophobic soil dead spots by allowing spray solutions to penetrate areas that may otherwise repel them.
Improving Soil Health

ORO-RZ® adjuvant improves the efficacy of soil-applied pesticides and nutrients. When tank mixed with pre-emergent herbicides it improves soil hydraulic conductivity, even in hydroscopic soils, to move the herbicide solution into soil pore spaces to lay down a uniform barrier of herbicide protection. ORO-RZ, when applied with nutrients such as NANOCAL, distributes the application uniformly throughout the soil profile boosting efficient uptake by the root system.

ORO-RZ for Pre-Emergent Weed Control

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.

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.

Applications & Uses

Applicable Crop
Application Instructions

ORO-RZ is a soil adjuvant to improve the distribution of pesticides and nutrients within the soil profile.


Use Rates

  • For Soil​​​​​​​

    • In furrow at planting with soil pesticides – Use 1 to 2 pints per acre
    • In pre-emergent herbicide sprays – Use 1 to 2 pints per acre
    • In broadcast tank mix solutions – Use 1 to 4 pints per acre
    • Through drip, microjet or sprinkler irrigation systems – Use 2 to 8 pints per acre
    • Through pivots – Use 2 to 8 pints per acre

  • For growing media​​​​​​​

    • 8 to 64 fluid ounces per ton of media (test rates prior to use)

Application directions

ORO®-RZ can be applied in-furrow, flood, microjet, sprinkler and other irrigation systems. It can also be applied in conjunction with most types of liquid fertilizer. In addition, it can be applied as a soil spray. When metering ORO-RZ directly into an irrigation system by means of a metering injection pump or suction regulated line, do not connect to an irrigation system used for chemical applications or directly to a public water system without a back siphon prevention system in place. Always connect to such systems in accordance with local and/or state regulations.
