Agrochemical update March 2015

Fenarimol (Rubigan SC) stocks to be used up

The registration for the powdery mildew active constituent Fenarimol (DuPont product Rubigan SC) has not been renewed. As such, growers have until 30 June 2016 to use up any stock they have of this agrochemical. After this date, leftover stock will need to be disposed of.

Some growers may wish to use up their stock of Rubigan SC by conducting a post-harvest application to control powdery mildew. When considering this option, growers should be aware of the CropLife Australia resistance management restrictions on the Group 3 fungicides. These state:

  • DO NOT apply more than two consecutive sprays of a Group 3 fungicide.
  • DO NOT apply more than three Group 3 sprays per season.
  • DO NOT use Group 3 fungicides curatively.

If disposal of unused stock is required, growers can register with ChemClear at or by calling toll free on 1800 008 182. Local Environment Protection Agencies may also be able to advise on other disposal mechanisms.

A list of alternative chemicals for the control of powdery mildew can be found on page 8 in the ‘Dog Book’ – accessible in several different formats on the AWRI website.
