Molinate

Molinate (ethyl N, N’-hexamethylenethiolocarbamate) is a pre and post-emergent, systemic thiocarbamate herbicide used exclusively in rice growing for the control of barnyard grasses (Echinochloa spp.) and silver top or brown beetle grass (Diplachne fusca).

Molinate review


Status: Review in progress

Update:

  • June 2013—toxicological and occupational health and safety reports published following a targeted consultation with affected industry and State departmental agencies.

Molinate review process

This timeline provides an overview of the stages and dates of the molinate review. The review commenced in 2003. A review scope document was published in 2003. In 2004, the APVMA received a toxicology assessment report for molinate, whilst the molinate review advisory committee was formed. Between 2004 and 2012 revised component reports for occupational health and safety, and environment were received and assessed. In 2011, registrants voluntarily amended product labels for use in closed delivery and supply systems only to reduce worker exposure to molinate. In April 2013, the APVMA released the toxicological and occupational health and safety (OHS) assessments for molinate. These assessments did not support the ongoing ground or aerial application of molinate, based on human health concerns. After consideration of the component assessments of molinate (toxicology, revised OHS and environment), the APVMA will publish a preliminary review findings report that will outline the proposed final regulatory actions for molinate. Following consideration of any public comments, the APVMA will release the molinate review findings report which will finalise the review of molinate.

Background

In May 2003, the APVMA began a review of molinate because of toxicological, occupational health and safety and environmental concerns and released the Molinate Review Scope Document (PDF, 50Kb). The scope document outlined the information needed to conduct a comprehensive scientific assessment of molinate.

In June 2004, the Advisory Committee on Chemicals Scheduling (ACCS) reconsidered the scheduling of molinate. The ACCS included molinate in Schedule 7 of the Standard for the Uniform Scheduling of Medicines and Poisons (SUSMP) (external site).

In June 2011, registrants voluntarily amended product labels in a collaborative effort with the APVMA to reduce worker exposure to molinate. Molinate product labels were amended for use in closed delivery and supply systems only.

In June 2013, the APVMA released the toxicological and occupational health and safety (OHS) assessments for molinate in combination with a targeted consultation with affected industry and State departmental agencies. These assessments did not support the ongoing ground or aerial application of molinate, based on human health concerns.

The findings of all the component assessments of molinate (toxicology, revised OHS and environment) will be considered and the APVMA will publish a preliminary review findings report that will outline the proposed final regulatory actions for molinate. With a release of the preliminary review findings report, a period for public comment will follow. After consideration of any submissions and comments, the APVMA will release the molinate review findings report which will finalise the review of molinate and outline regulatory steps for existing products.
