Improving barnyard grass control with Facet L + ORO-HSMOC

Share on:

Barnyard grass (Echinochloa crus-galli) is a major weed challenge in rice production, significantly impacting crop yield and quality. Traditional control methods often face application and efficacy limitations.

This field trial investigated the efficacy of Facet® L, a common herbicide, against barnyard grass in rice when partnered with ORO®-HSMOC, a high-performance methylated seed oil adjuvant. Different rates of ORO-HSMOC with Facet L were compared to Facet L in a tank mix with an industry standard COC.

What % of control on barnyard grass was achieved using ORO-HSMOC and Facet L?

A tank mix of ORO-HSMOC and Facet L, at lower rates demonstrated a significant control of barnyard grass compared to the COC in both applications, achieving over 85% control at 15 days after application (DAA) and maintaining over 90% control at 20 DAA.

These results show that ORO-HSMOC is a more effective tank mix partner with Facet L for weed management programs.
